Weaponized Interdependence and Financial Statecraft

LESSON METADATA

SECTION 0 — Why This Lesson Exists

The transition from the post-war institutional order to the contemporary era of financial statecraft represents a fundamental rupture in International Relations theory. For decades, the prevailing paradigm suggested that economic interdependence would act as a pacifying force, reducing the likelihood of conflict through mutual vulnerability. However, the architecture built at Bretton Woods evolved not into a system of shared security, but into a network topology where centrality conferred coercive capability rather than protection. This lesson confronts the central puzzle: how does the very connectivity that enables global trade become the mechanism for geopolitical coercion? Understanding this requires moving beyond traditional state-centric realism to analyze the networked nature of finance itself. The student will learn that financial power is not merely a function of GDP or reserve holdings, but a structural advantage derived from occupying key nodes in the global payment system. This distinction is critical for analyzing contemporary conflicts where economic warfare substitutes for kinetic force.

The theoretical lineage of this lesson traces from the institutionalism of L6 through to the network theory articulated by Farrell and Newman (2019). Early scholarship, such as Drezner (1999), treated sanctions as blunt instruments of state coercion, assuming rational actors who could calculate compliance costs. However, contemporary analysis reveals that the efficacy of sanctions depends on the structural position of the target within a network. The US dollar’s dominance in clearing and settlement is not an accident of history but a maintained position of structural power. This lesson interrogates how this centrality is weaponized, moving beyond the simple binary of “sanctions work” or “sanctions fail.” It asks instead how they function through specific mechanisms like secondary sanctions and SWIFT exclusions. The curriculum placement here follows L16 (Bretton Woods) to show how the original institutional design inadvertently created the vulnerabilities exploited today.

The African perspective is not merely a case study but the primary lens through which this structural violence must be understood. For the continent, financial statecraft is not abstract theory; it is the reality of debt distress, fuel insecurity, and fertilizer price volatility. When Western powers weaponize interdependence, the Global South faces the brunt of these shocks without political recourse. African scholarship, from Fanon to contemporary analyses by Grovogui and Mamdani, highlights how colonial-era financial structures persist in modern sanctions regimes. This lesson reconstructs that vantage point, showing how debt traps and currency volatility are not market outcomes but geopolitical choices. The student will recognize that “financial sovereignty” is the specific vocabulary African states use to describe their struggle against external coercion.

Furthermore, this lesson must address the distributional question: who bears the cost? Western perspectives often focus on compliance rates or target state behavior. However, an African vantage point reveals that the costs are distributed unevenly across the Global South. The impact of sanctions on food security, specifically through fertilizer imports priced in dollars, demonstrates a mechanism of indirect coercion. This lesson integrates these perspectives to show that the network is not neutral; it reflects historical power asymmetries. By mastering this material, students will be able to critique the normative claims of “smart sanctions” and understand why humanitarian carve-outs often fail to reach intended beneficiaries. The analysis extends beyond US policy to include Chinese parallel systems and UN resolutions on unilateral coercive measures.

The central capability developed here is the ability to distinguish between liquidity constraints and network topology constraints. A state may have reserves but still be cut off from the global system if its banks are disconnected from SWIFT. This distinction is vital for analyzing cases like Russia in 2022 or Iran in 2019. The lesson prepares the student for L19 (energy) and L48 (chokepoints), where physical infrastructure intersects with financial control. Without understanding the financial architecture, one cannot analyze energy geopolitics correctly. Therefore, this module serves as the foundational layer for geoeconomic analysis.

Finally, mastering this lesson allows the student to evaluate policy interventions critically. They will be able to predict how states adapt through parallel banking systems like CIPS or SPFS. They will understand the limitations of “de-dollarization” campaigns and why they are often defensive reactions rather than offensive strategies. The learning outcomes include the ability to map a sanctions regime, identify its network vulnerabilities, and assess the distributional impacts on third parties. This prepares the student for the complex reality where financial warfare is the new battlefield, requiring a sophisticated understanding of both economic mechanisms and political power dynamics.

SECTION 2.2 KEY IDEA 1 — Network Theory and the Structural Basis of Coercion

Bolded Causal Claim: The fundamental causal claim advanced by Farrell and Newman (2019) is that power in the contemporary international system derives not from material capabilities alone, but from the positionality within a network of interdependence. Specifically, centrality confers power because it allows the controller to influence the flow of goods, capital, and information. This relationship is asymmetric: A can punish B for non-compliance by cutting off access to the network, whereas B cannot reciprocate without suffering catastrophic systemic costs. The claim posits that “interdependence is a form of vulnerability,” meaning that the very integration that generates prosperity simultaneously creates the leverage points necessary for coercion. In the context of financial statecraft, this manifests as the ability to exclude non-compliant actors from the global payment system. This structural power operates independently of political will; it exists because the architecture itself relies on a few critical nodes (e.g., US dollar clearing) that process the majority of global transactions. Consequently, sanctions are effective not merely because of the threat of retaliation, but because the target is structurally dependent on the network for basic economic functionality. The claim implies that power is endogenous to the network design, not exogenous to state military or economic size.

Mechanism: The mechanism through which this causal claim operates involves two distinct but related topological features: the panopticon and the chokepoint. The panopticon effect occurs when a central node (like the US financial system) can observe and regulate all transactions passing through it, effectively creating an informational advantage that translates into coercive capability. When a state attempts to bypass this node, the system detects it because the flow of information is centralized. The chokepoint mechanism refers to specific nodes where the volume of traffic is so high that removing them causes systemic disruption for third parties. In financial terms, the US dollar clearing system serves as a chokepoint because nearly all international trade requires settlement in dollars or through correspondent banks domiciled in the United States. When the US freezes assets or excludes a bank from SWIFT, it does not just harm the target state; it threatens the liquidity of the entire global banking system if too many chokepoints are removed simultaneously. This creates a feedback loop where the defender of the network (the US) gains power by maintaining the system’s integrity, while challengers must choose between isolation or adaptation. The mechanism relies on trust: banks participate in the dollar system because they expect reciprocity and safety. Weaponization breaks this trust, forcing participants to weigh the cost of compliance against the risk of being cut off.

Scope Conditions: The efficacy of weaponized interdependence is contingent upon specific scope conditions that often limit its universal application. First, network density matters; if a target state has diversified its trade and financial partners sufficiently, the chokepoint effect diminishes. This explains why comprehensive sanctions against Iran were less successful than those against Russia in terms of regime change, though both faced severe economic pain. Second, the level of trust within the network is critical. If participants believe the hegemon will use the system for arbitrary coercion, they will seek alternatives (de-dollarization), which erodes the mechanism over time. Third, the legal and regulatory framework must support extraterritorial reach; US laws like the Helms-Burton Act or secondary sanctions rely on the assumption that foreign banks will comply with domestic US law to avoid reputational risk. If these laws are perceived as overly aggressive, they trigger resistance rather than compliance. Finally, the technological capacity of the target matters. A state without a sophisticated financial bureaucracy cannot easily build alternative systems (like SPFS) quickly enough to offset exclusion from the primary network. These conditions suggest that weaponized interdependence is most potent against states that are deeply integrated into the Western-led architecture but lack the resources to pivot rapidly toward alternative networks.

Observable Implications: The observable implications of this theory are found in the varying outcomes of sanctions regimes across different historical contexts. When a chokepoint is successfully weaponized, we observe a rapid contraction in the target’s access to global markets, often accompanied by capital flight and currency devaluation among trading partners fearing secondary liability. We also observe the emergence of parallel architectures, such as the creation of new clearinghouses or the shift toward commodity-backed currencies, indicating the network is fracturing under pressure. In cases where the panopticon effect dominates, we see increased surveillance and compliance monitoring by private banks to avoid sanctions violations, effectively privatizing enforcement. A critical implication is the emergence of “sanctions fatigue” among third-party states; as the cost of complying with US demands rises, they begin to seek alternatives, leading to a gradual erosion of the hegemon’s centrality. Empirical evidence from the Atlantic Council sanctions tracker shows that while comprehensive sanctions often cause humanitarian distress, targeted financial exclusions (like SWIFT bans) have higher success rates in altering behavior if the target lacks deep ties with non-aligned partners. However, we also observe resilience where targets rebuild capacity through regional partnerships, suggesting that network power is not permanent but must be constantly renewed.

Perspective Note (five traditions in brief): The African perspective views weaponized interdependence primarily through the lens of historical coloniality and the structural inequalities embedded in the global financial architecture. Scholars like Achille Mbembe and Amina Wadud argue that the current network topology is not neutral but reflects a post-colonial order where the Global South remains structurally dependent on Western nodes for liquidity and trade settlement. From this vantage point, sanctions are often viewed as a continuation of economic warfare that prioritizes geopolitical objectives over human rights and development needs in Africa. The African perspective emphasizes that while network theory explains the mechanics of exclusion, it obscures the historical context of why African economies were integrated into these networks on unequal terms. This is critical because it reveals that “interdependence” often masks dependency relationships established during the Cold War era, where infrastructure was built to serve Western interests rather than local development. Consequently, the African critique focuses on the distributive consequences: when sanctions are weaponized against a state with which Africa trades, African economies bear the brunt of inflation and food insecurity because they lack alternative payment channels. This perspective challenges the neutrality of the panopticon concept by arguing that the “view” is not equal; Western states see the network clearly, while African states often operate in the blind spots of surveillance and compliance regimes designed to protect their own citizens from liability.

The Chinese perspective interprets weaponized interdependence as a challenge to financial sovereignty and a driver of de-dollarization strategies. Beijing views US-centric financial networks as tools of containment rather than neutral infrastructure, leading to investments in alternative systems like CIPS (Cross-Border Interbank Payment System). The Chinese stance emphasizes the need for multipolarity where no single state can dictate the rules of global finance, advocating for local currency settlement to reduce vulnerability to unilateral coercive measures.

The Russian perspective frames sanctions as a form of economic warfare that threatens national survival and seeks to build a parallel financial architecture insulated from Western influence. Moscow argues that the US weaponization of its dollar hegemony violates international law and necessitates a defensive response through gold-backed settlements and bilateral trade agreements, viewing centrality not as power but as an existential threat.

The Western perspective generally defends sanctions as a tool of coercive diplomacy within a rules-based order, arguing that they are necessary to enforce international norms while minimizing humanitarian impact. However, internal critiques acknowledge the collateral damage and the risk of undermining the legitimacy of the financial system itself, leading to debates over proportionality and the effectiveness of secondary sanctions on third-party states.

The UN perspective focuses on humanitarian carve-outs and the Special Rapporteur’s role in monitoring unilateral coercive measures, emphasizing that financial restrictions must not violate international human rights law or impede the delivery of essential goods like food and medicine. The UN seeks to balance security concerns with the obligation to protect vulnerable populations from the fallout of geopolitical conflicts played out in financial markets.

SECTION 2.3 KEY IDEA 2 — SWIFT and Dollar Clearing: How the US Converts Financial Centrality into Coercive Power

Bolded Causal Claim: The United States converts its structural centrality in global financial networks into coercive power by leveraging the U.S. dollar as the primary medium of exchange and clearing currency, allowing it to exclude non-compliant states from the international payment system via SWIFT (Society for Worldwide Interbank Financial Telecommunication) membership termination or freezing assets held in U.S. jurisdictions.

Mechanism: This coercion operates through a network theory framework articulated by Farrell and Newman (2019), where the “panopticon” of global finance relies on intermediary banks that must choose between their own commercial interests and alignment with U.S. security priorities. The mechanism functions because the majority of global transactions are denominated in USD, processed through New York clearing houses, or routed through correspondent accounts held at U.S. banks (e.g., JP Morgan Chase, Citibank). When a state like Iran is targeted, the U.S. does not need to physically block funds; it instructs intermediary banks to cease processing transactions involving that target. The cost of compliance for these banks—loss of access to the dollar liquidity pool—is so high that they self-regulate before explicit orders are given. This creates a “chokepoint” effect where the network architecture itself becomes the weapon. In the 2012 case against Iran, the U.S. utilized this mechanism to restrict oil exports by freezing Iranian Central Bank assets and threatening correspondent banks. Similarly, in February 2022, following Russia’s invasion of Ukraine, the U.S. Treasury Department moved to cut off Russian state-owned enterprises from SWIFT. This action severed the ability of the Russian state to receive international payments for gas or trade goods, effectively weaponizing the network’s topology. The mechanism relies on the assumption that no viable alternative payment system exists with sufficient liquidity depth to replace the dollar clearing infrastructure.

Scope Conditions: The efficacy of this mechanism is contingent upon three specific conditions: first, the global dominance of the U.S. dollar in foreign exchange reserves and trade invoicing; second, the lack of a credible alternative interbank messaging or clearing system that has achieved universal adoption (prior to 2022); and third, the legal jurisdiction of U.S. courts over non-U.S. entities that interact with the U.S. financial system. If a target state possesses significant hard currency reserves denominated in non-dollar assets (e.g., gold or yuan) and can access a parallel network like China’s CIPS without friction, the mechanism weakens. Furthermore, this power is asymmetric; it cannot be reciprocated by smaller states because they lack the network centrality to impose comparable costs on others. The scope condition also depends on the willingness of Western banks to comply with U.S. secondary sanctions, a factor that fluctuates based on political pressure from Washington and the risk of losing access to New York markets.

Observable Implications: Empirically, the weaponization of financial networks manifests as immediate liquidity shocks for targeted states. Following the 2012 sanctions on Iran, oil exports dropped significantly not because of a physical blockade but because buyers could not settle payments in dollars without risking U.S. asset freezes. In 2022, Russia’s exclusion from SWIFT for major banks led to a fragmentation of its payment system, forcing Moscow to rely on barter trade and the CIPS platform for settlement. The observable outcome is a bifurcation of the global financial system: a “compliant” dollar network and an emerging “non-compliant” parallel architecture. This also triggers secondary effects such as inflation in targeted economies due to supply chain disruptions, capital flight, and devaluation of local currencies. In 2023, analysts noted that while Russia’s economy remained resilient in the short term, the long-term cost was reduced access to Western technology and insurance markets, compounding the financial isolation initiated by SWIFT cuts.

Perspective Note (five traditions in brief): African Perspective: For African states, the weaponization of dollar clearing represents a continuation of colonial-era financial dependency where sovereignty is subordinated to the security interests of a distant hegemon. Scholars like Amina Mama and Mahmood Mamdani argue that this architecture reproduces neo-colonial hierarchies where Global South nations are treated as subjects rather than equals, unable to participate in global finance without U.S. permission. This impacts food security directly; when fuel or fertilizer payments are blocked via dollar clearing, rural livelihoods collapse regardless of the geopolitical justification. Chinese Perspective: Beijing views this mechanism as a demonstration of American hegemony that threatens the multipolar order. China interprets SWIFT exclusions not merely as legal enforcement but as political coercion that undermines the principle of non-interference in domestic affairs. Consequently, China advocates for de-dollarization and alternative settlement systems to protect its Belt and Road Initiative partners from similar vulnerability. Russian Perspective: Moscow frames this power as “economic warfare” designed to strangle a sovereign state’s ability to govern. Russian analysts emphasize that SWIFT cuts are an illegal use of force under international law, violating the principle of economic sovereignty. They view the mechanism as a tool for regime change rather than legitimate statecraft, arguing that it destabilizes global markets by creating artificial scarcity in energy trade. Western Perspective: Washington justifies these actions as necessary to enforce international norms and protect national security interests against malign actors. Western analysts emphasize the distinction between targeted sanctions and comprehensive embargoes, arguing that cutting off specific entities minimizes humanitarian harm while maximizing pressure on regimes violating human rights or international law. However, critics within the West acknowledge the collateral damage to innocent populations and the risk of eroding trust in the financial system itself. UN Perspective: The United Nations emphasizes the need for humanitarian carve-outs and adherence to international human rights law when implementing financial restrictions. UN Special Rapporteurs monitor unilateral coercive measures to ensure they do not impede the delivery of essential goods like food and medicine. The UN seeks to balance security concerns with the obligation to protect vulnerable populations, often calling for a moratorium on sanctions that violate the sovereignty of non-targeted states or disrupt global supply chains necessary for basic survival.

SECTION 2.4 KEY IDEA 3 — Sanctions Design: Smart vs Comprehensive, Secondary Sanctions, and Extraterritorial Reach

Bolded Causal Claim: The design of sanctions—specifically the use of secondary sanctions and extraterritorial jurisdiction—significantly increases coercive leverage by penalizing third-party entities that engage with a targeted state, thereby expanding the reach of U.S. law beyond its borders to coerce non-targeted nations into compliance.

Mechanism: This mechanism relies on “long-arm” jurisdiction where U.S. laws (such as those enforced by the Office of Foreign Assets Control) assert authority over foreign entities that interact with the U.S. financial system or use U.S.-origin technology. Secondary sanctions threaten to cut off these third parties from dollar access if they trade with a sanctioned target, like Russia or Iran. The mechanism functions through “compliance costs”: banks and corporations calculate that the cost of violating U.S. law (asset freezes, reputational damage) exceeds the profit gained from trading with the target. In the case of maximum pressure on Iran (2018-2019), the U.S. threatened secondary sanctions on Indian oil importers who bought discounted Iranian crude. The mechanism works by creating a “compliance cascade” where intermediaries self-censor to avoid risk, effectively extending the reach of U.S. policy without direct military or physical intervention.

Scope Conditions: This design is effective only when the target state lacks sufficient trade alternatives and when third-party states fear retaliation from the U.S. more than they value their economic ties to the target. The mechanism weakens if the target state develops parallel financial channels (e.g., Russia’s SPFS) that bypass SWIFT, or if third parties are willing to accept the risk of sanctions evasion. Additionally, the scope condition depends on the global demand for specific commodities; if a target state offers unique resources (like rare earth minerals or discounted energy), third parties may ignore secondary sanctions despite the risks. The mechanism also has limits regarding humanitarian exemptions; if food and medicine trade is legally protected, the coercive pressure on the target regime diminishes because the economic pain cannot be fully transmitted to the population without violating international norms.

Observable Implications: In practice, secondary sanctions lead to observable shifts in trade patterns and corporate behavior. During the 2018-2019 Iran sanctions, India significantly reduced its oil imports from Tehran due to fears of being cut off from dollar clearing, even though the U.S. did not formally sanction Indian banks directly. Similarly, Iraq faced difficulties paying for electricity imports because Western suppliers feared secondary sanctions liability. The observable outcome is often a “de-risking” phenomenon where banks close accounts in sanctioned countries entirely, rather than just restricting specific transactions. This leads to market fragmentation and higher transaction costs globally. Over time, this design can backfire by incentivizing the creation of non-dollar payment systems, thereby accelerating the very de-dollarization that Western policymakers seek to prevent.

Perspective Note (five traditions in brief): African Perspective: African scholars and policymakers view secondary sanctions as a violation of the principle of non-interference and a threat to food security. For nations like Ethiopia or Kenya, which rely on imported fuel and fertilizer, U.S. pressure on third parties disrupts essential imports without targeting the specific regime responsible for instability. This perspective highlights how financial coercion disproportionately affects the Global South, where states lack the diplomatic leverage to negotiate exemptions and suffer collateral damage in terms of debt distress and inflation. Chinese Perspective: China critiques secondary sanctions as a violation of international law and an infringement on national sovereignty. Beijing argues that such measures undermine the multilateral trading system by allowing one nation to unilaterally dictate trade rules for others. Consequently, China promotes alternative payment systems like CIPS to provide a sovereign-safe haven for nations unwilling to submit to U.S. extraterritorial jurisdiction, framing this as a defense of the multipolar order. Russian Perspective: Moscow characterizes secondary sanctions as “economic warfare” and an illegal extension of military force. Russian analysts argue that these measures violate the UN Charter by imposing unilateral coercive measures without Security Council authorization. They view the threat of asset freezes against third parties as a tool to destabilize global markets and punish states for maintaining diplomatic ties with Russia, framing it as a breach of fundamental international norms. Western Perspective: Washington defends secondary sanctions as a necessary tool for enforcing compliance and protecting national security interests. Western policymakers argue that these measures are proportional and targeted, distinguishing them from comprehensive embargoes that harm civilian populations. However, internal critiques within the West acknowledge that extraterritorial reach can damage U.S. reputation and lead to trade wars with allies who feel coerced into violating their own economic interests for American security goals. UN Perspective: The United Nations advocates for a strict adherence to international human rights law when designing sanctions regimes, emphasizing the need for humanitarian carve-outs. UN bodies monitor the impact of secondary sanctions on third-party states, warning against measures that violate the sovereignty of non-targeted nations or impede essential trade in food and medicine. The Special Rapporteur on unilateral coercive measures calls for a moratorium on such practices unless they are approved by the Security Council, ensuring that financial restrictions do not become tools of regime change rather than instruments of peace enforcement.

SECTION 2.5 — KEY IDEA 4: Evasion and Adaptation in Financial Architecture

Bolded Causal Claim: When hegemonic financial coercion targets a state’s access to the global payment system, target states will not remain passive; they will actively construct parallel architectures or utilize alternative settlement mechanisms, though the efficacy of these adaptations is strictly bounded by liquidity constraints and network depth.

Mechanism: The mechanism operates through institutional bifurcation. Following Farrell and Newman’s (2019) framework of weaponized interdependence, states seek to decouple from the “panopticon” of U.S.-centric financial governance. Russia’s creation of the System for Transfer of Financial Messages (SPFS) following its 2022 exclusion from SWIFT demonstrates this adaptive capacity. SPFS functions not merely as a messaging tool but as a signaling device to partner states that they may transact without relying on correspondent banks vulnerable to U.S. secondary sanctions. Similarly, China’s Cross-Border Interbank Payment System (CIPS) offers an alternative clearing channel, though it remains smaller than SWIFT and lacks the deep liquidity of the U.S. dollar market. The European Union attempted this through INSTEX in 2019 to trade with Iran without dollars, but its limited scope revealed that adaptation is often a defensive posture rather than a strategic offensive one. Furthermore, non-architectural adaptations include the use of commodity-backed currencies (gold) and decentralized finance (crypto), which bypass traditional banking rails entirely. However, these methods carry high transaction costs and volatility risks. The mechanism relies on “networked sovereignty,” where states leverage existing bilateral trade relationships to create a new web of payment settlements that do not rely on the hegemon’s central bank or clearinghouses.

Scope Conditions: This adaptation is viable only when three conditions are met: first, the target state must have sufficient foreign exchange reserves in non-dollar assets (euros, yuan, gold) to facilitate bilateral settlement; second, there must be a critical mass of trading partners willing to accept parallel systems without fear of secondary sanctions; third, the global network topology must contain enough “weak links” or chokepoints that can be bypassed. If the hegemon controls the majority of global reserves (as with the USD’s ~60% share in M2 money stock per COFER data), adaptation is limited to niche markets rather than broad systemic replacement. The scope condition also depends on the political will of intermediaries; for instance, Indian banks may process transactions for Russia via SPFS but may avoid doing so if U.S. regulators threaten their correspondent accounts. Consequently, adaptation is often partial and fragmented rather than total systemic replacement.

Observable Implications: Observable indicators of this dynamic include a measurable increase in bilateral trade settlement agreements excluding the dollar, such as China-Russia oil trades settled in yuan or rubles post-2022. Another indicator is the volatility of alternative currencies; when CIPS usage spikes, it often correlates with a decline in SWIFT transaction volume for specific corridors. Furthermore, the emergence of crypto-assets as a settlement layer creates new regulatory challenges, observable through the rise of stablecoins pegged to non-dollar reserves in sanctioned jurisdictions. The fragmentation of the financial system is also visible in the “shadow banking” sector, where states use private blockchain networks or messaging apps (like Telegram-based payment systems) to move value. These implications suggest a trend toward a multipolar financial architecture, though one that remains deeply hierarchical with the U.S. dollar still at the apex of liquidity.

Perspective Note (five traditions in brief): African Perspective: African scholars like Jean-Loup Amselle and Achille Mbembe argue that this adaptation is not merely technical but a matter of survival against structural violence. Bayart’s concept of “politics of the belly” suggests that for Global South states, financial sovereignty is not an abstract legal right but a prerequisite for feeding populations; therefore, reliance on Western payment systems is seen as a form of colonial dependency that must be severed through whatever means necessary, even if it fragments global liquidity. The African Union’s stance prioritizes food security over financial orthodoxy, viewing parallel systems as essential to prevent the weaponization of food imports (fertilizer, fuel) which are cleared via these networks. Chinese Perspective: Beijing views CIPS and SPFS partnerships as legitimate exercises in “financial sovereignty” rather than geopolitical aggression. The narrative emphasizes that no state should be forced to choose between economic development and national security, framing parallel architecture as a defensive measure against unilateral coercion. Russian Perspective: Moscow frames the creation of SPFS as a necessary response to Western hostility, justifying the bifurcation of financial infrastructure as a legitimate exercise of sovereign rights under international law. They argue that the West’s refusal to grant equal access constitutes an illegal embargo rather than a standard sanction. Western Perspective: U.S. policymakers and think tanks (e.g., Atlantic Council) often describe parallel systems as inefficient and risky, arguing they fragment global liquidity and increase transaction costs for everyone. The Western view prioritizes the integrity of SWIFT and the rule-based order, viewing fragmentation as a threat to financial stability rather than an acceptable adaptation. UN Perspective: UN agencies emphasize that while sovereignty is respected, fragmentation must not violate humanitarian obligations. The Special Rapporteur on unilateral coercive measures notes that parallel systems should not be used to circumvent sanctions regimes that target individuals or groups involved in human rights abuses, balancing the right to financial autonomy with the imperative of preventing illicit finance and funding terrorism.

SECTION 2.6 — KEY IDEA 5: The Distributional Question of Coercion

Bolded Causal Claim: Weaponized interdependence imposes asymmetric costs on third-party states, particularly those in the Global South, where the economic fallout from financial coercion against a primary target is redistributed through global supply chains and financial markets, disproportionately affecting food security and debt stability.

Mechanism: The distributional mechanism operates through price transmission and liquidity shock. When a major economy like Russia or Iran is sanctioned, its exports (oil, gas, wheat) are priced in dollars but paid for with non-dollar currencies that may be scarce elsewhere. This forces importing nations to pay premiums to secure supply, effectively transferring wealth from the Global South to the sanctioning hegemon or neutral intermediaries. For example, when U.S. sanctions restricted Russian oil sales after 2022, global prices shifted; while some states secured discounts, others faced higher costs due to insurance and shipping risks (the “Arctic route” premium). This is compounded by debt distress: African nations holding bonds in dollars face higher borrowing costs as investors flee riskier assets. The mechanism also involves “secondary sanctions,” where non-targeted firms are penalized for transacting with the target, forcing them to exit markets regardless of their own compliance posture. This creates a “spillover effect” where the cost is borne by citizens in countries that never sanctioned the primary target but rely on global markets.

Scope Conditions: The severity of distributional costs depends on the degree of dependency on the sanctioned commodity or currency. States heavily reliant on Russian energy (like Turkey or Egypt) face higher inflationary pressure than those with diversified suppliers. Additionally, the scope is conditioned by the depth of the global financial system; if a large portion of trade is dollar-denominated, any disruption causes systemic volatility affecting all non-dollar economies. The mechanism also depends on the political economy of the importing state; authoritarian regimes may absorb costs through subsidies (like Egypt’s fuel subsidies) while democracies face electoral backlash from inflation. Furthermore, the condition of “humanitarian carve-outs” matters; if food and medicine are exempted from sanctions, distributional harm is mitigated. However, enforcement gaps often mean that essential goods are still blocked or delayed, exacerbating the cost for the vulnerable.

Observable Implications: Empirical evidence includes rising inflation rates in African nations post-2022, correlating with global energy price shocks and dollar volatility. The volume of local currency settlements (LCS) in BRICS+ countries has expanded, indicating a shift away from dollar dependency as a response to distributional harm. Another observable metric is the increase in debt restructuring requests by low-income countries facing higher interest rates due to U.S. Treasury bond issuance dominance. Furthermore, the “cost of compliance” for multinational corporations is visible through reduced market access in sanctioned regions, leading to layoffs and wage stagnation in third-party countries. The distributional question also reveals a divergence in wealth accumulation: while the sanctioning state may achieve security goals, its allies often face higher prices, creating internal friction within alliances.

Perspective Note (five traditions in brief): African Perspective: Drawing on Mamdani and Grovogui, African scholars argue that the distributional costs of sanctions are a form of “structural violence” that disproportionately impacts the poor. The African Development Bank (AfDB) data highlights how fertilizer shortages from sanctioned Russian exports directly threaten food security, leading to malnutrition rates that cannot be offset by diplomatic rhetoric. For Africa, the question is not about abstract financial sovereignty but about the right to survival; sanctions that disrupt global fertilizer markets are viewed as an existential threat that overrides geopolitical calculations. Chinese Perspective: Beijing frames distributional costs as a consequence of Western hegemony and advocates for “de-dollarization” to mitigate these harms. The narrative suggests that a multipolar currency system would distribute risks more evenly, preventing any single state from imposing economic warfare on others. Russian Perspective: Moscow attributes the distributional harm to Western monopoly power over global finance, arguing that their sanctions regime transfers wealth from the Global South to the U.S. Treasury. They posit that breaking this dependency is necessary to restore a fairer global order where costs are not externalized onto peripheral states. Western Perspective: The United States and EU typically argue that sanctions are targeted and that distributional costs are unintended side effects they seek to minimize through humanitarian exemptions. However, critics within the West note that “smart sanctions” often fail due to network effects, meaning that civilian populations in third countries still suffer from supply chain disruptions, challenging the claim of minimal collateral damage. UN Perspective: The UN Special Rapporteur on unilateral coercive measures emphasizes that distributional harms violate the right to food and health under international law. The UN argues that sanctions regimes must include rigorous human rights impact assessments before implementation to ensure that the costs do not fall disproportionately on vulnerable populations in non-targeted states.

SECTION 2.7 — FIVE PERSPECTIVES IN DEPTH

2.7.1 African Perspective (PRIMARY)

The African perspective on weaponized interdependence does not merely accept the premise that financial networks are neutral infrastructure; rather, it reconstructs them as a continuation of colonial extraction mechanisms. This vantage point contributes a critical epistemological correction: sovereignty is not an abstract legal status but a material capacity to control economic flows, which has been systematically eroded by the architecture of the US dollar and SWIFT. Where Western theories often treat sanctions as tools of “coercive diplomacy,” African scholarship frames them as instruments of “necro-economics” that determine who can access life-sustaining resources (Mbembe 2003; Grovogui 1995). This perspective reveals that the distributional costs borne by the Global South are not “collateral damage” but intentional features of a system designed to maintain hegemony.

Achille Mbembe’s concept of necropolitics provides the foundational theoretical lens for understanding financial exclusion in Africa. Necropolitics describes the power to dictate who may live and who must die, extending beyond physical violence to economic suffocation. When a state is excluded from SWIFT or frozen by asset freezes, its population enters a state of suspended animation where food security becomes a matter of survival rather than policy (Mbembe 2013). This perspective occludes the Western claim that sanctions are “smart” and targeted; instead, it argues that in an interdependent world, targeting a central bank inevitably targets the population’s access to fertilizer, fuel, and medicine. The African contribution is the insistence on “food sovereignty” rather than “food security.” Food security implies receiving aid or market goods from outside; food sovereignty implies control over local production and distribution (Nkrumah 1970). Weaponized interdependence undermines sovereignty by making African economies dependent on US-controlled payment rails, rendering them vulnerable to external coercion.

The theoretical lineage here draws heavily from dependency theory and structuralism, updated for the digital age. Walter Rodney’s analysis of how capital accumulation in the metropole requires underdevelopment in the periphery (Rodney 1972) finds its modern expression in financial sanctions. When the US freezes assets or restricts dollar clearing, it effectively weaponizes the historical asymmetry of trade relations. This is not a neutral enforcement of rules but an application of power through infrastructure. Francis Ng’etich and others argue that this dynamic reproduces colonial hierarchies where the Global North sets the terms of engagement (Bayart 2013). Bayart’s work on the “political economy of aid” suggests that sanctions are merely a more aggressive form of structural adjustment, imposing austerity through exclusion rather than conditionality.

A critical distinction emerges when analyzing evasion and adaptation. Western observers often view parallel systems like CIPS or SPFS as purely strategic alternatives. The African perspective views them as necessary acts of resistance to maintain sovereignty against external coercion (Mamdani 2016). For African scholars, the choice between the dollar and local currency is not just economic but political: it is a choice between subordination and autonomy. The creation of BRICS+ payment mechanisms is not merely trade diversification; it is an assertion of the right to define one’s own financial destiny. This aligns with Amílcar Cabral’s argument that liberation requires the construction of new institutions, not just the rejection of old ones (Cabral 1973).

The distributional question is central to this perspective. The cost of sanctions falls disproportionately on the most vulnerable: smallholder farmers who cannot access fertilizer due to frozen supply chains, and consumers facing inflation spikes from fuel shortages. This is analyzed through the lens of human rights law as interpreted in African contexts (Tamale 2018). The Special Rapporteur on unilateral coercive measures highlights this, but African scholarship goes further by questioning the legitimacy of the sanctions regime itself. If a sanction regime violates the right to food and health under international law, then participation in it is complicit in human rights violations (Aning 2020). This perspective challenges the Western notion that economic pressure is a legitimate tool of statecraft when it results in civilian suffering.

Furthermore, the African vantage point reveals what the other four perspectives miss: the internal dynamics of the Global South. The West focuses on US interests; China on strategic autonomy; Russia on survival; the UN on humanitarian carve-outs. Africa focuses on interdependence itself as a trap. The “network theory” proposed by Farrell and Newman (2019) describes how centrality creates power, but African scholars argue that this centrality was never built for equality; it was built for extraction. The network is designed to keep the periphery dependent. When a state like Iran or Russia is sanctioned, the West claims to punish them, but in reality, the system punishes the entire network of developing nations that rely on those states for trade. This “third-country effect” is not an accident; it is a structural feature of the dollar hegemony (Grovogui 2018).

Finally, this perspective offers a normative alternative: the right to self-determination in economic affairs. The African Union’s push for local currency settlement and the expansion of AfCFTA are not just trade agreements but constitutional attempts to build sovereignty outside the Western-dominated financial order. This is distinct from the Chinese narrative of “non-interference” because it explicitly links sovereignty to human survival and development rights. It challenges the UN to move beyond humanitarian exemptions toward a fundamental restructuring of global financial governance. The African perspective concludes that weaponized interdependence is not a bug of the system but its operating feature, and that true security requires breaking the dependency on the dollar, not just managing it.

2.7.2 Chinese Perspective

The Chinese perspective treats weaponized interdependence as a strategic vulnerability to be neutralized through financial sovereignty and multipolarity. Beijing views the US-dominated financial architecture, particularly SWIFT and USD clearing, not merely as a network but as a tool of geopolitical containment. This view is rooted in the principle of “non-interference” and the defense of national sovereignty against external coercion (Drezner 1999). For China, sanctions are not legitimate diplomatic tools but acts of economic warfare that violate the norms of international trade. Consequently, the Chinese response focuses on building parallel infrastructure to ensure resilience.

Key mechanisms in this perspective include the development of CIPS (Cross-Border Interbank Payment System) and local currency settlement agreements within BRICS+. The logic is straightforward: if the US can weaponize the dollar, China must build a system that cannot be weaponized against it. This is not merely about trade; it is about ensuring that China’s economic integration does not expose it to unilateral coercion. The Chinese perspective contributes the concept of “financial sovereignty” as a prerequisite for national security. It argues that interdependence should be based on mutual benefit rather than hierarchy, though in practice, this often means building alternative systems to avoid US reach.

However, this perspective occludes the distributional costs borne by third parties. While China advocates for local currency settlement, it does not explicitly address how this shifts risks to non-aligned states or smaller economies that lack the capacity to manage multi-currency clearing. The Chinese narrative focuses on strategic autonomy and resilience, often framing sanctions as a breach of international law rather than a systemic issue requiring structural reform. This occlusion is evident in the reluctance to acknowledge the humanitarian impact of sanctions regimes unless directly threatened themselves.

The evidence for this perspective includes China’s rapid expansion of trade in local currencies with Russia, Iran, and African nations following 2022. The creation of CIPS demonstrates a commitment to reducing reliance on US clearing houses. However, strong objections exist: critics argue that building parallel systems creates fragmentation that reduces overall global efficiency. Furthermore, while China promotes “win-win” cooperation, its own trade practices have been accused by Western observers of state-led industrial policy that distorts markets (Atlantic Council sanctions tracker). The Chinese perspective thus contributes a model of resilience but occludes the potential for reduced global liquidity and increased transaction costs in a fragmented world.

2.7.3 Russian Perspective

The Russian perspective frames weaponized interdependence as “economic warfare” and a direct attack on national sovereignty. Following the 2022 sanctions, Moscow views the exclusion from SWIFT and asset freezes not as diplomatic pressure but as an existential threat requiring total mobilization of domestic industry and alternative financial channels (Nephew 2018). This view is rooted in a realist understanding of international politics where power dictates security. For Russia, the US dollar is not a neutral medium of exchange but a weaponized asset that can be used to strangle an adversary.

The mechanism of adaptation here is the creation of parallel financial architecture: SPFS (System for Financial Messages) and the use of gold or crypto as settlement mediums. The Russian argument is that reliance on Western finance was always a vulnerability, and true security requires autarky in critical sectors. This perspective occludes the long-term economic costs of isolationism, such as technology stagnation and inflation, framing them as necessary sacrifices for survival. It also occludes the suffering of Russian civilians under price controls and rationing, prioritizing regime stability over domestic welfare in the short term.

The evidence includes Russia’s pivot to trading with China, India, and Central Asia using non-dollar currencies. This demonstrates a successful evasion strategy but highlights the limits of adaptation: without access to advanced Western technology (semiconductors, chips), industrial growth is constrained regardless of currency choice. Strong objections include the risk that this fragmentation creates a “two-tier” global economy where only major powers can afford isolationist strategies. The Russian perspective contributes a stark warning about the dangers of financial hegemony but occludes the moral imperative to protect human rights from economic coercion.

2.7.4 Western Perspective

The Western perspective, primarily US and EU, views sanctions as a legitimate tool of “coercive diplomacy” within the rule-based international order. The core claim is that weaponized interdependence can be managed through “smart sanctions” that target elites rather than populations (Farrell & Newman 2019). This view relies on the premise that financial networks are neutral infrastructure that can be regulated to serve democratic values. The mechanism is secondary sanctions: using US law to penalize third parties who trade with sanctioned entities, thereby extending reach beyond territorial borders (Drezner 1999).

However, this perspective increasingly acknowledges its own failures. Critics within the West note that “smart sanctions” often fail due to network effects; cutting off a bank in Iran or Russia inevitably disrupts supply chains for food and fuel in third countries like India or Iraq. The Atlantic Council sanctions tracker documents these unintended consequences, leading to self-critique on collateral damage. The Western view also emphasizes humanitarian carve-outs, arguing that exemptions are necessary to protect civilians. This occludes the fact that exemptions are often bureaucratic hurdles that still result in delays and shortages for vulnerable populations.

The evidence includes the 2018-19 maximum pressure campaign on Iran and its effects on third countries like India (oil imports) and Iraq (electricity payments). Western policymakers argue these are unintended side effects, but critics point out they were foreseeable given the centrality of the dollar clearing system. Strong objections include the claim that unilateral sanctions violate international law and undermine multilateralism. The Western perspective contributes a framework for humanitarian protection but occludes the structural reality that the financial architecture itself is inherently coercive when one currency dominates global trade.

2.7.5 UN Perspective

The UN perspective, articulated through the Special Rapporteur on unilateral coercive measures, emphasizes that distributional harms violate fundamental human rights under international law. The core claim is that sanctions regimes must include rigorous human rights impact assessments before implementation to ensure costs do not fall disproportionately on vulnerable populations in non-targeted states. This view treats financial coercion as a potential violation of the right to food and health (UN Human Rights Council).

The mechanism here is legal: the UN General Assembly resolutions calling for an end to unilateral coercive measures that violate international law. The perspective argues that sovereignty includes the right to economic development without external interference, provided human rights are respected. This occludes the political reality that major powers often ignore these resolutions when it suits their strategic interests. The evidence includes reports from the UN Office on Drugs and Crime (UNODC) tracking the impact of sanctions on civilian populations in Syria, Iran, and Venezuela.

Strong objections include the argument that the UN lacks enforcement power; without compliance from major financial centers like New York or London, resolutions remain symbolic. The UN perspective contributes a normative framework for human rights protection in finance but occludes the structural limitations of international law against state power. It calls for a shift from “smart sanctions” to “humanitarian-first” regimes, arguing that security cannot come at the cost of basic survival rights.

2.7.6 Comparison Matrix

2.8 WORKED EXAMPLE (I do)

The 2022 sanctions against Russia following its full-scale invasion of Ukraine illustrate how financial centrality is converted into coercive power and how a targeted state adapts. Within days, G7 and EU actors froze a large share of Russia’s central-bank reserves and excluded selected Russian banks from SWIFT, while also restricting technology and energy-related finance. The case is analytically useful because it combines a classic chokepoint intervention with an unusually rapid attempt to build parallel financial infrastructure.

Levels of analysis. At the individual level, the sanctions worked through compliance incentives: risk-averse bankers, lawyers, and corporate officers de-risked Russian counterparties beyond the legal minimum, while Russian citizens faced inflation, capital controls, and restricted access to foreign currency. At the state level, the Central Bank of Russia, the Finance Ministry, state energy firms, and Western treasuries and central banks were the principal actors; Russia raised interest rates, imposed capital controls, and redirected trade, while the United States and European Union coordinated designations and exemptions. At the systemic level, the episode tested dollar hegemony, SWIFT’s role as a network hub, and the post-Cold War security order; it accelerated debates about multipolarity without immediately displacing the dollar. At the transnational level, correspondent banking chains, multinational firms, commodity traders, diaspora remittances, and humanitarian organizations transmitted both coercion and spillover costs across borders.

Mechanism. The mechanism is Farrell and Newman’s chokepoint effect amplified by secondary sanctions. SWIFT is not itself a payment system, but its messaging standard and network position make it a coordination device for correspondent banking; exclusion raises transaction costs and uncertainty. Dollar clearing through New York adds a second chokepoint because most global trade and reserve management still depends on access to US financial infrastructure. The freeze of central-bank assets attacked Russia’s macroeconomic buffer, while export controls and financial sanctions aimed to degrade military-industrial capacity. The panopticon effect mattered too: because transactions are visible through compliance systems, private actors over-complied, extending state coercion through market discipline. Russia’s countermeasures—SPFS messaging, CIPS linkage, yuan invoicing, gold accumulation, crypto channels, and shadow-fleet logistics—were attempts to reroute around these chokepoints. The result was not immediate collapse but a bifurcated adaptation: Russia retained energy revenues during the initial price spike, yet faced long-term constraints in aviation, semiconductors, and advanced manufacturing.

Perspective reconstruction. From an African vantage, the 2022 sanctions are legible as another instance in which financial decisions taken in the North become terms-of-trade and debt shocks in the South. African economies dependent on imported wheat, fuel, and fertilizer faced price spikes and tighter dollar liquidity, while AfDB analyses documented rising food insecurity and fiscal pressure; many African governments therefore treated non-alignment as a material necessity rather than mere diplomatic hedging. The case also resonates with longer African critiques of external economic coercion, from Nkrumah’s neo-colonialism to Rodney’s underdevelopment thesis, because it shows how control over payment rails can discipline states without formal colonial rule. At the same time, African perspectives must acknowledge that Russia’s invasion itself disrupted Black Sea grain exports, so not all cost can be attributed to sanctions. The African view contributes a distributional lens that the other four often underweight, but it can understate the security aims of Ukraine’s partners.

From a Chinese perspective, the case confirms that financial centrality is a strategic weapon and that dependence on dollar clearing creates vulnerability. Beijing’s response has been cautious: it has expanded CIPS and yuan settlement while avoiding full exposure to secondary sanctions, suggesting that de-dollarization is incremental and interest-driven rather than revolutionary. Chinese analysts often frame the sanctions as accelerating multipolarity, but the continued dominance of the dollar in reserves and trade shows that alternatives remain partial.

From a Russian perspective, the sanctions are economic warfare waged by an adversarial coalition, and adaptation is presented as evidence of sovereign resilience. Moscow’s creation of parallel payment channels, capital controls, and import-substitution programs demonstrates state capacity under pressure, while its rhetoric blames Western measures for global inflation and food insecurity. This perspective explains the mechanics of evasion but often obscures the causal role of the invasion and the domestic costs of militarization.

From a Western perspective, the sanctions are coercive diplomacy designed to raise the cost of aggression, degrade Russia’s war capacity, and signal commitment to Ukraine. Policymakers emphasize targeted design, humanitarian exemptions, and coordination among allies, while self-critique focuses on overcompliance, third-country spillovers, and the risk of overusing financial tools. This perspective best captures intent and institutional design, but it can understate how extraterritorial enforcement coerces non-targeted actors.

From a UN perspective, the case raises questions of proportionality, civilian protection, and the legality of unilateral coercive measures. UN actors have emphasized humanitarian carve-outs, food and energy access, and the need to prevent sanctions from undermining basic rights, while noting that major powers often ignore resolutions when strategic interests are at stake. The UN perspective supplies normative guardrails but lacks enforcement against dominant financial centers.

Adjudication. The Western perspective best explains the immediate coercive mechanism: it accurately identifies how SWIFT exclusion, reserve freezes, and secondary sanctions were designed to constrain Russia’s fiscal and military capacity. However, it misses the transnational distributional costs and the long-term incentive structure for parallel financial architecture, which the African and Chinese perspectives foreground. The African perspective best explains who bears the cost and why Global South states resist alignment, but it can underweight Russian agency and the security rationale of Ukraine’s supporters. The Chinese perspective best explains systemic incentives for de-dollarization, yet it risks overstating the pace of change and understating China’s own stake in dollar liquidity. The Russian perspective explains adaptation but functions partly as legitimation of aggression. The UN perspective is indispensable for humanitarian limits but cannot by itself explain power. On balance, the case is best explained by a synthesis in which Western mechanism analysis is retained, African distributional analysis is added, and Chinese systemic analysis is used to qualify claims about durability; no single perspective is sufficient.

SECTION 2.9 PROBLEM PAIR (We do)

Tasks

1. Distinguish primary, secondary, and extraterritorial sanctions in the 2018-19 Iran maximum-pressure case, and identify whether US power in this episode operated mainly through law, markets, or military threat.
2. Trace the causal chain from US withdrawal from the JCPOA to India’s cessation of Iranian oil imports and Iraq’s electricity-payment arrears; identify the chokepoint and the point at which private actors, not states, became the effective enforcers.
3. Apply the four levels of analysis—individual, state, systemic, and transnational—to explain why the same US policy produced different outcomes in India and Iraq.
4. Reconstruct how the African/Global South, Chinese, Russian, Western, and UN perspectives would each evaluate the case, including what each perspective reveals and what it occludes.
5. Compare India and Iraq as cases of differential vulnerability: why was coercion more complete in Indian oil imports and more destabilizing in Iraqi electricity supply?
6. Specify scope conditions and falsifiers: under what conditions would secondary sanctions fail to coerce third countries, and what evidence would show that they did fail?

MODEL ANSWER

The 2018-19 maximum-pressure campaign against Iran is a canonical case of weaponized interdependence because the coercive effect on third countries was produced less by direct US-Iran bilateral measures than by the extraterritorial reach of US financial law. After the United States withdrew from the JCPOA and reimposed sanctions, secondary sanctions threatened foreign persons and firms with exclusion from US markets and the dollar-based financial system if they continued to transact with Iran. This converts US centrality in clearing, correspondent banking, and dollar liquidity into coercive power: the chokepoint is not a physical strait but the institutional architecture through which most international payments are cleared and most trade is financed. Farrell and Newman’s framework helps explain why the threat need not be executed to be effective; the panopticon effect means that private actors, uncertain about enforcement but aware of catastrophic downside risk, self-censor and de-risk. Nephew’s analysis of sanctions design underscores that modern sanctions are calibrated to exploit this anticipatory behavior, while Drezner’s earlier work reminds us that sanctions effectiveness depends on target vulnerability and sender credibility, not merely on legal authority.

India’s oil imports illustrate the mechanism. New Delhi had strategic and commercial reasons to maintain Iranian crude purchases, and it initially benefited from temporary waivers. Yet after waivers expired in 2019, Indian refiners and banks faced the prospect that any Iran-related transaction could trigger US penalties, loss of dollar access, or exclusion from US markets. The result was not simply a negotiated bilateral concession by India to Washington, but a compliance cascade through refiners, insurers, shippers, and state-owned banks. India diversified toward other suppliers because the cost of maintaining the Iran channel exceeded the benefit once private financial intermediaries withdrew. Iraq presents a harder case: Iranian electricity and gas imports were embedded in Iraq’s power system, and payment channels were constrained by sanctions-related restrictions and banking de-risking. Arrears and supply interruptions followed, translating a financial dispute into domestic electricity shortages and political instability. The contrast matters: coercion was more complete where substitutes existed, as in Indian crude sourcing, and more destabilizing where infrastructure dependence was high, as in Iraqi power.

The levels of analysis clarify why the same policy had different effects. At the individual level, compliance officers, bank risk committees, and corporate counsel became the operational enforcers of US policy; their incentives favored over-compliance because the cost of a false negative, a sanctions violation, far exceeded the cost of a false positive, lost business. At the state level, India and Iraq made different calculations: India could absorb diversification costs and preserve broader US ties, while Iraq faced immediate energy-security and fiscal constraints. At the systemic level, dollar centrality and payment messaging created the coercive architecture; even where alternative currencies existed, the marginal cost of exiting the dollar channel was high. At the transnational level, shipping, insurance, marine finance, and commodity trading transmitted pressure across jurisdictions, so that a US legal threat became a global market signal.

Perspective reconstruction shows why the case is contested. The Western perspective frames maximum pressure as coercive diplomacy intended to change Iranian nuclear and regional behavior, while also generating self-critique about humanitarian costs, overreach, and the erosion of trust in diplomatic agreements. The Russian perspective interprets such measures as economic warfare and uses them to justify building parallel payment systems and closer ties with sanctioned states. The Chinese perspective treats extraterritorial sanctions as an infringement on financial sovereignty and a reason to accelerate de-dollarization, local-currency settlement, and alternative clearing arrangements. The African and broader Global South perspective emphasizes distributional asymmetry: states not party to the US-Iran dispute bear costs through fuel prices, fertilizer markets, food insecurity, debt stress, and constrained development finance. The UN perspective, including the work of special procedures on unilateral coercive measures, stresses that humanitarian carve-outs for food, medicine, and essential services often fail in practice because banks over-comply and payment channels collapse, so legal exemptions do not guarantee access.

Adjudication requires separating effectiveness from legitimacy. On effectiveness, the evidence supports a conditional conclusion: secondary sanctions coerced third-country behavior in 2018-19, especially where private actors faced high US market exposure and where substitutes were available. On legitimacy, the same mechanism is more contested because it imposes costs on non-targeted populations and undermines the principle that sanctions should be targeted, proportionate, and subject to humanitarian safeguards. Early’s work on third-party sanctions suggests that coercion of bystanders is not an accidental byproduct but a structural feature of financial statecraft. The strongest counterargument to the effectiveness claim is that coercion may be temporary and self-undermining: as targeted and third countries invest in alternative payment systems, non-dollar settlement, and barter or gold workarounds, the sender’s network advantage erodes. Falsifiers would include sustained India-Iran trade despite US threats, functioning humanitarian payment channels with minimal arrears, or evidence that maximum pressure accelerated rather than constrained Iran’s nuclear program. The case therefore supports the narrower theoretical claim that weaponized interdependence is powerful but path-dependent: it works through network centrality and private anticipation, and its durability depends on whether the targeted network remains indispensable.

SECTION 2.10 INDEPENDENT MEMO (You do)

(a) Case description

In 2023, the United States expanded secondary sanctions against non-Russian entities accused of facilitating Russia’s war economy, including banks, shipping intermediaries, and commodity traders in third countries. Several Global South economies that had increased trade with Russia after 2022 faced heightened compliance costs, delayed payments, and de-risking by correspondent banks. Some governments argued that the measures were necessary to close sanctions loopholes; others argued that they imposed extraterritorial obligations on states not party to the Russia-Ukraine conflict and disrupted legitimate trade, energy imports, and development finance. The case is analytically useful because it separates the question of whether secondary sanctions change behavior from the question of who bears their costs, and because it tests whether alternative payment systems and non-dollar settlement can reduce US leverage over time. It also raises the problem of over-compliance: private banks may refuse even legally permitted transactions, producing humanitarian and commercial effects that exceed the stated scope of sanctions. Analysts disagree over whether such measures strengthen coercive diplomacy or accelerate the fragmentation of global finance.

(b) Required memo headings as prompts

• Mechanism: Identify the specific channel through which US sanctions threats alter third-country behavior—legal, financial, or market—and specify the scope conditions under which that mechanism fails.
• Perspective reconstruction: Reconstruct how the African/Global South, Chinese, Russian, Western, and UN perspectives would each evaluate the 2023 expansion, stating what each perspective contributes and what it occludes.
• Historical analogue: Compare this case to a prior episode of secondary sanctions or financial coercion, such as the 2018-19 Iran maximum-pressure campaign or the 2014 Russia sanctions, and state what is similar, what differs, and what the analogy cannot explain.
• Falsifiers: List two observable developments that would weaken your explanation and two that would strengthen it.

(c) Self-check

Self-check: Did you distinguish description of the 2023 sanctions expansion from explanation of its effects, prediction about future de-dollarization, and prescription about whether the policy should continue?

SECTION 2.11 HINGE QUESTION

Question: In the 2018-19 Iran maximum-pressure case, what best explains why India halted Iranian oil imports after waivers expired?

A. The United States threatened direct military action against Indian refineries.
B. Secondary sanctions threatened foreign firms with loss of US market access and dollar-clearing privileges, producing anticipatory compliance by private actors.
C. Iran refused to continue selling oil to India at discounted prices.
D. UN Security Council sanctions made all Iranian oil purchases illegal for UN member states.

Correct answer: B.

Distractor diagnoses

• A: This option conflates financial coercion with military coercion. The mechanism in the case was not a threat of force against Indian infrastructure but the extraterritorial reach of US financial law and the risk of exclusion from dollar markets.
• C: This option reverses causality. Iran sought buyers for its oil; Indian refiners and banks withdrew because compliance risk and loss of dollar access made the Iran channel unsustainable, not because Iran refused to sell.
• D: This option misstates the legal basis. The 2018-19 measures were primarily US sanctions reimposed after withdrawal from the JCPOA, not a new UN Security Council prohibition binding all member states; it overstates multilateral authority and understates unilateral financial leverage.

Five numbered analysis questions

1. Trend. Looking at Tables 1 and 2 together, describe the trajectory of USD dominance in global finance from 2000 to 2023. Is the evidence more consistent with (a) a structural collapse of dollar hegemony, (b) a slow, contested diversification, or (c) stability with marginal erosion? Justify with two specific data points and note what the data cannot show.

2. Level of analysis. Weaponized interdependence is sometimes described as a “systemic” phenomenon and sometimes as a “state” phenomenon. Using the tables, identify at least two levels of analysis at which the data operate (individual/bank, state, systemic, transnational), and explain why the COFER series is a systemic-level indicator while the India–Russia rupee settlement is a state-level adaptation.

3. Perspective reconstruction (all five). Reconstruct how each of the five perspectives would read Tables 3 and 4: (a) African — cost-bearing and food/fuel/fertilizer shocks; (b) Chinese — de-dollarization opportunity and CIPS growth; (c) Russian — sanctions as economic warfare and SPFS; (d) Western — coercive diplomacy plus self-critique; (e) UN — humanitarian carve-outs and the Special Rapporteur on unilateral coercive measures. Which perspective best explains the wheat-price and fertilizer rows, and why?

4. Interpretation. Does the BRICS/local-currency data in Table 4 support the claim that sanctions on Russia in 2022 “broke” dollar dominance? Adjudicate between the “acceleration” thesis (sanctions sped up pre-existing diversification) and the “rupture” thesis (sanctions created a new non-dollar order), citing the CIPS, SPFS, and INSTEX rows.

5. Limitation. Identify three specific limitations of these data for testing claims about weaponized interdependence: one concerning measurement (what SWIFT/COFER do not capture), one concerning causal identification (why the Russia GDP figure does not isolate sanctions), and one concerning perspective bias (whose costs are and are not counted in Table 3).

SECTION 3 — DUAL-CODED VISUAL ANCHOR

Visual 1 — “The Chokepoint Network” (hand-drawn graph)

What to draw. A hub-and-spoke network on an A4 page. Draw one large central circle (≈6 cm diameter) labeled “SWIFT / CHIPS / USD clearing”. Around it, draw eight to ten smaller circles (≈2 cm) representing peripheral nodes: label them US Treasury, Federal Reserve, Major US banks, EU banks, Asian banks, Iran (2012), Russia (2022), Global South importer, Commodity trader, Correspondent bank. Draw straight lines from each peripheral node to the central hub. Thicken the lines into the hub to suggest traffic concentration.

Labels to place. On the central hub, write “CHOKEPOINT” in red. Above the hub, draw a stylized eye (an oval with a pupil) labeled “PANOPTICON: transaction visibility”. On two peripheral nodes (Iran, Russia), draw a red “X” or a broken line to indicate exclusion. Add a small legend box: solid line = normal traffic; broken line = sanctioned/excluded.

Perspective overlay to annotate. In the margin, write two short annotations: (Western) “Efficiency + compliance leverage: the hub lowers transaction costs and enforces rules.” (African) “Vulnerability: peripheral nodes cannot route around the hub; exclusion is collective punishment of non-targets.” Draw a dashed arrow from the African annotation to the Global South importer node.

Visual 2 — “Sanctions Escalation Ladder” (hand-drawn vertical ladder)

What to draw. A vertical ladder with six rungs, bottom to top, drawn as horizontal bars connected by two vertical rails. Label each rung from bottom to top: (1) Diplomatic protest, (2) Targeted / “smart” sanctions (individuals, entities), (3) Sectoral sanctions (energy, finance, defense), (4) Comprehensive sanctions (trade embargo), (5) Secondary sanctions (extraterritorial reach), (6) Financial exclusion (SWIFT cutoff, central-bank asset freeze). Draw an arrow on the left rail pointing upward labeled “Escalation.”

Labels to place. On the right side, place two timeline markers with leader lines: a dot on rung 2–3 labeled “Iran 2012 (EU oil embargo + SWIFT)” and a dot on rung 6 labeled “Russia 2022 (SWIFT + ~$300bn freeze)”. At the top, write “Ceiling: military force” in grey. At the bottom, write “Floor: diplomacy”.

Perspective overlay to annotate. Annotate rung 5 (secondary sanctions) with a bracket and the note: “Coerces third countries (India, Iraq) without their consent — the extraterritorial mechanism.” Annotate rung 6 with: “UN perspective: humanitarian carve-outs required; Special Rapporteur on unilateral coercive measures.” Add a small African-perspective note at the bottom: “Costs fall on food/fuel/fertilizer importers not on the ladder.”

Visual 3 — “Distributional Cost Map” (hand-drawn world map)

What to draw. A simplified world map (continents as rough outlines). Shade the Global South (Africa, parts of Latin America, South/Southeast Asia, Middle East) in a gradient: light yellow = low cost exposure, deep orange/red = high cost exposure (food, fuel, fertilizer). Shade the US and EU in light blue (sanctioning states). Shade Russia in grey (target). Draw thick arrows from Russia/Ukraine grain regions and from Gulf fertilizer regions toward Africa and South Asia, with a red “X” or break symbol on the arrows to indicate disrupted flows. Draw a separate thin arrow from the US/EU toward the Global South labeled “humanitarian carve-outs (partial).”

Labels to place. Legend: Red/Orange = cost-bearing (food, fuel, fertilizer, debt); Blue = sanctioning states; Grey = target state. Title: “Who bears the cost of weaponized interdependence?” Add three callout boxes: (Africa) “AfDB: fertilizer 2–3× price spikes”; (South Asia) “India: oil import disruption, rupee settlement”; (Middle East) “Iraq: electricity payments blocked.”

Perspective overlay to annotate. In the margin, write the five perspective one-liners: African — “Costs are externalized to non-targets”; Chinese — “Opportunity for de-dollarization”; Russian — “Economic warfare”; Western — “Coercive diplomacy with self-critique”; UN — “Humanitarian carve-outs and due process.” Draw a bracket grouping the African and UN notes as “cost-bearing / protective” perspectives.

Summary (3–5 sentences)

Weaponized interdependence describes how states occupying central positions in economic networks—especially the US in dollar clearing and SWIFT—convert structural centrality into coercive power through panopticon (visibility) and chokepoint (exclusion) effects. The 2012 Iran and 2022 Russia cases show escalation from targeted sanctions to financial exclusion, with secondary sanctions extending US reach to third countries such as India and Iraq. Evasion efforts (CIPS, SPFS, INSTEX, gold, crypto) have produced parallel architecture but not yet a systemic alternative, as COFER data show slow USD erosion rather than collapse. The distributional costs fall disproportionately on the Global South through food, fuel, fertilizer, and debt channels, generating African, Chinese, Russian, Western, and UN perspectives that disagree on legitimacy, efficacy, and remedy. The data support a “slow diversification” reading, not a “dollar collapse” reading, but measurement and causal-identification limits remain severe.

SECTION 5 — FEYNMAN COMPRESSION

Step 1 — Explain without jargon. Imagine a town where every shop, bank, and household must use one central switchboard to make payments. The switchboard operator can see every transaction (that is the panopticon) and can cut off anyone’s line (that is the chokepoint). If the operator is a powerful country, it can punish a rival by cutting its line—and because everyone else also needs the switchboard, the operator can threaten them too if they keep trading with the rival. That is weaponized interdependence: power comes not from owning the goods but from sitting at the center of the network everyone must use. The 2022 Russia case is the clearest example: Russia was cut off from SWIFT and had roughly $300 billion of central-bank reserves frozen, and other countries felt pressure to stop buying Russian oil or face US penalties.

Step 2 — Mark gaps. (a) I initially conflated SWIFT (messaging) with CHIPS/Fedwire (settlement); the lesson distinguishes them—SWIFT exclusion raises costs and signals risk, but dollar clearing is the deeper chokepoint. (b) I under-specified the African perspective: it is not merely “costs exist” but a claim about externalization and voice, grounded in AfDB food/fuel/fertilizer/debt analyses. (c) I treated “de-dollarization” as a single trend; the data show it is fragmented—CIPS grows, SPFS stalls, INSTEX failed, BRICS Pay is not operational. (d) I did not yet specify the falsifiers that would change the conclusion.

Step 3 — Reread verification. Re-reading Farrell and Newman (2019, 2023): confirmed that panopticon and chokepoint are network-structural effects, not just policy choices, and that they depend on hub centrality and the absence of ready substitutes. Re-reading Drezner (1999) and Nephew (2018): confirmed that “smart” sanctions are designed to reduce humanitarian harm but that comprehensiveness and secondary reach often reintroduce broad costs. Re-reading Early (2015): confirmed that evasion is systematic and that sanctions-busting networks (front companies, re-flagging, alternative messaging) are a predictable adaptation. Re-reading the AfDB analyses and FAO data: confirmed the food/fuel/fertilizer/debt channel as the primary African cost vector. The COFER and SWIFT figures support “slow diversification, not collapse.”

Step 4 — Analogy with explicit limits. Analogy: a single dominant railway hub through which all freight must pass; the hub owner can inspect cargo (panopticon) and close the yard (chokepoint), and can threaten shippers who route to a rival. Limits: (i) railways are physical and slow to reroute, whereas financial networks can in principle be re-wired faster—yet in practice network effects and trust make rerouting hard; (ii) the analogy implies a single owner, whereas financial centrality is a public-private hybrid (US state + private banks + SWIFT cooperative); (iii) the analogy omits the legal dimension—extraterritorial US law, not just network position, does much of the coercive work; (iv) the analogy cannot capture the distributional asymmetry: railway closure hurts the hub’s customers, but financial exclusion’s worst costs fall on third parties (Global South importers) who are not parties to the dispute.

Step 5 — Rewrite. Weaponized interdependence is the conversion of structural centrality in economic networks into coercive power, operating through two mechanisms: the panopticon effect (visibility into transactions) and the chokepoint effect (the ability to deny access). The US occupies the central hub in dollar clearing and SWIFT, which it used against Iran (2012) and Russia (2022), escalating from targeted sanctions to financial exclusion and secondary sanctions that coerce non-targeted states such as India and Iraq. Evasion has produced partial alternatives—CIPS grows, SPFS and INSTEX faltered, BRICS Pay is not operational—so the data show slow diversification of reserves and settlement, not a collapse of dollar dominance. The costs are distributed asymmetrically: food, fuel, fertilizer, and debt burdens fall on the Global South, which is why African, Chinese, Russian, Western, and UN perspectives diverge on legitimacy, efficacy, and remedy. The conclusion is falsifiable: a sustained collapse of the USD reserve share, a functioning large-scale non-dollar settlement system, or sanctions with no third-country spillover would each overturn it.

7.2 Three-Question Debrief

1. Which mechanism in this lesson did you initially treat as an outcome rather than a process, and how would you now describe its causal chain?
2. Which perspective did you find most difficult to steel-man, and what evidence would be needed to make that reconstruction more credible?
3. What is one falsifier that would weaken your current conclusion about whether sanctions are coercively effective in a given case?
