Chokepoints Review: Sanctions, Financial Networks, and the Weaponization of Global Interdependence

Books / Economic Statecraft & Geopolitics

Chokepoints is most useful when it shows that globalization did not erase power; it concentrated power inside networks. Payments, chips, energy, shipping, and technology standards can become instruments of statecraft when access is asymmetric.

Edward Fishman’s Chokepoints is most useful as a map of hidden economic leverage. Chokepoints is most useful when it shows that globalization did not erase power; it concentrated power inside networks. Payments, chips, energy, shipping, and technology standards can become instruments of statecraft when access is asymmetric. The analysis below tests the network logic against financial data, sanctions policy, and the practical limits of coercion.

To test Chokepoints fairly, the review combines Fishman’s thesis with Treasury doctrine, IMF reserve data, and the mechanics of payments and export controls. Economic statecraft should be judged by the specific network dependency it exploits, not by dramatic rhetoric about ‘economic war.’

Economic leverage is never just a list of sanctions. It is a relationship between a scarce node, a target’s dependence, allied coordination, and the cost of substitution. Every section below asks which of those variables is doing the real work.

Globalization created networks, and networks created leverage

Fishman’s organizing idea is that interdependence did not make geopolitics obsolete. It created concentrated nodes—financial rails, reserve currencies, semiconductor tools, shipping services, and technology platforms—where a small number of governments and firms can impose disproportionate costs.

This is why the language of chokepoints is more useful than the language of simple trade dependence. A country may trade with hundreds of partners yet still rely on one settlement currency, one class of chipmaking tools, or a small group of insurers and logistics providers. For Chokepoints, that evidence changes the estimate of replaceability: a network node becomes coercive power only while the target cannot move transactions, technology, or trade elsewhere at tolerable cost.

Network power is not permanent. Once a chokepoint is used coercively, targets invest in bypasses, substitutes, reserves, and domestic capability. Leverage carries a depreciation rate. In Chokepoints, the counterfactual must separate visible economic pain from evidence that the target would otherwise have chosen a different political course.

Corporate strategists should map networks by replaceability, not spend. A component representing 2% of cost can still be existential if no substitute exists. The same logic that guides statecraft should guide supply-chain risk management. Chokepoints becomes operational when the exact network node, legal authority, target dependence, coalition, and credible escape route are written down explicitly.

For the Chokepoints section “Globalization created networks, and networks created leverage,” monitor network dependence before headline sanctions outcomes. Reserve composition, correspondent-bank access, export-license exposure, coalition breadth, and evasion cost indicate whether leverage is strengthening or decaying.

Dollar centrality remains a strategic asset

Fishman’s account of economic warfare depends heavily on the dollar and the legal-financial infrastructure around it. The IMF’s 2026Q1 COFER data still showed the dollar at 57.13% of allocated official foreign-exchange reserves, evidence that predictions of immediate displacement remain premature.

Reserve status matters because cross-border trade, funding, banking, and asset markets generate repeated contact with U.S.-linked institutions. That gives U.S. authorities jurisdictional and informational leverage that is much larger than America’s share of global merchandise trade alone would imply. For Chokepoints, that evidence changes the estimate of replaceability: a network node becomes coercive power only while the target cannot move transactions, technology, or trade elsewhere at tolerable cost.

De-dollarization is real at the margin. Central banks can diversify reserves, firms can invoice in other currencies, and sanctioned states have strong incentives to construct alternatives. But network effects make replacement slow. In Chokepoints, the counterfactual must separate visible economic pain from evidence that the target would otherwise have chosen a different political course.

For investors, the relevant question is not whether the dollar will ‘collapse.’ It is where dollar dependence intersects with sanctions exposure, refinancing risk, and cross-border liquidity. Currency architecture is part of geopolitical due diligence. Chokepoints becomes operational when the exact network node, legal authority, target dependence, coalition, and credible escape route are written down explicitly.

For the Chokepoints section “Dollar centrality remains a strategic asset,” monitor network dependence before headline sanctions outcomes. Reserve composition, correspondent-bank access, export-license exposure, coalition breadth, and evasion cost indicate whether leverage is strengthening or decaying.

SWIFT is powerful because messaging sits inside a wider system

Public debate often treats exclusion from SWIFT as if the messaging network itself were a magical sanction. Fishman’s framework is more precise: financial isolation works because messaging, correspondent banking, reserve assets, compliance rules, and legal jurisdiction reinforce one another.

A bank can theoretically communicate outside SWIFT, but replacing trusted counterparties, clearing relationships, and compliant access to major currencies is much harder than replacing one messaging protocol. For Chokepoints, that evidence changes the estimate of replaceability: a network node becomes coercive power only while the target cannot move transactions, technology, or trade elsewhere at tolerable cost.

Overstating SWIFT can lead policymakers to miss other nodes. Payments are a stack, and coercion can enter at clearing banks, custodians, exchanges, insurers, correspondent accounts, or export licensing. In Chokepoints, the counterfactual must separate visible economic pain from evidence that the target would otherwise have chosen a different political course.

Businesses should diagram their own payment stack with the same discipline. Which banks, currencies, jurisdictions, and service providers are necessary for a transaction to complete? A sanctions program can break the chain at any one of them. Chokepoints becomes operational when the exact network node, legal authority, target dependence, coalition, and credible escape route are written down explicitly.

For the Chokepoints section “SWIFT is powerful because messaging sits inside a wider system,” monitor network dependence before headline sanctions outcomes. Reserve composition, correspondent-bank access, export-license exposure, coalition breadth, and evasion cost indicate whether leverage is strengthening or decaying.

Iran showed that sanctions can create negotiating leverage

Fishman draws on his policy experience to explain how coordinated financial sanctions increased pressure on Iran before the 2015 nuclear agreement. The case illustrates the conditions under which economic coercion can support a diplomatic objective.

Multilateral participation matters because leakage determines pain. When allies restrict the same channels, evasion becomes more expensive and the target has fewer substitute markets. For Chokepoints, that evidence changes the estimate of replaceability: a network node becomes coercive power only while the target cannot move transactions, technology, or trade elsewhere at tolerable cost.

The causal claim should remain disciplined. Sanctions were one factor among domestic politics, oil markets, diplomacy, and security calculations. Economic pain does not automatically translate into the exact political concession a sender wants. In Chokepoints, the counterfactual must separate visible economic pain from evidence that the target would otherwise have chosen a different political course.

The operator lesson is analogous to commercial negotiation: leverage is useful only when tied to a credible deal structure. Pressure without an off-ramp can harden resistance and teach the counterparty how to operate without you. Chokepoints becomes operational when the exact network node, legal authority, target dependence, coalition, and credible escape route are written down explicitly.

Reserve composition, correspondent-bank access, export-license exposure, coalition breadth, and evasion cost indicate whether leverage is strengthening or decaying.

Russia exposed both the reach and limits of financial warfare

Sanctions after Russia’s invasion of Ukraine demonstrated how quickly major economies could freeze assets, restrict banks, target technology exports, and pressure energy-linked finance. The scale of coordination was historically significant.

At the same time, Russia adapted through trade rerouting, alternative payment channels, import substitution, third-country intermediaries, and continued commodity revenue. Economic warfare imposed costs without producing immediate strategic capitulation. For Chokepoints, that evidence changes the estimate of replaceability: a network node becomes coercive power only while the target cannot move transactions, technology, or trade elsewhere at tolerable cost.

This distinction is crucial. A sanction can be effective at reducing capacity or raising cost while failing to force a near-term policy reversal. Success must be defined against the objective. In Chokepoints, the counterfactual must separate visible economic pain from evidence that the target would otherwise have chosen a different political course.

Boards should apply the same metric discipline to geopolitical risk controls. ‘Compliant’ is not the same as ‘resilient,’ and ‘cost imposed’ is not the same as ‘risk removed.’ Define what outcome each control is meant to achieve. Chokepoints becomes operational when the exact network node, legal authority, target dependence, coalition, and credible escape route are written down explicitly.

For the Chokepoints section “Russia exposed both the reach and limits of financial warfare,” monitor network dependence before headline sanctions outcomes. Reserve composition, correspondent-bank access, export-license exposure, coalition breadth, and evasion cost indicate whether leverage is strengthening or decaying.

China changes the scale of the problem

Economic statecraft against a deeply integrated manufacturing power is harder than sanctions against a smaller, more isolated economy. China occupies important nodes of its own across manufacturing, batteries, minerals, electronics, and industrial inputs.

That mutual dependence turns coercion into a two-sided exposure. Export controls can slow access to frontier technology, but retaliation can target supply chains where the sender is dependent. For Chokepoints, that evidence changes the estimate of replaceability: a network node becomes coercive power only while the target cannot move transactions, technology, or trade elsewhere at tolerable cost.

The result is not symmetrical in every sector. Some chokepoints are concentrated in U.S.-allied technology ecosystems; others sit in Chinese manufacturing or processing capacity. Strategy must be sector specific. In Chokepoints, the counterfactual must separate visible economic pain from evidence that the target would otherwise have chosen a different political course.

For companies, ‘China risk’ should be decomposed into revenue concentration, supplier concentration, regulatory exposure, technology dependence, and substitution time. A single geopolitical label hides the operational mechanism. Chokepoints becomes operational when the exact network node, legal authority, target dependence, coalition, and credible escape route are written down explicitly.

For the Chokepoints section “China changes the scale of the problem,” monitor network dependence before headline sanctions outcomes. Reserve composition, correspondent-bank access, export-license exposure, coalition breadth, and evasion cost indicate whether leverage is strengthening or decaying.

Semiconductors reveal the difference between market share and chokepoint control

Advanced chips are produced through a globally fragmented chain involving design software, manufacturing equipment, foundries, materials, and packaging. No single country owns the entire stack, but certain nodes are highly concentrated.

That structure explains why export controls can have force even without a dominant share of final-chip assembly. Control over scarce upstream technology can constrain downstream production far away. For Chokepoints, that evidence changes the estimate of replaceability: a network node becomes coercive power only while the target cannot move transactions, technology, or trade elsewhere at tolerable cost.

Technology controls also accelerate substitution efforts. Every restriction changes capital allocation in the target country and can create political support for expensive domestic duplication. In Chokepoints, the counterfactual must separate visible economic pain from evidence that the target would otherwise have chosen a different political course.

Investors should value suppliers not only by revenue but by system criticality. A small company with unique process knowledge can carry geopolitical importance far beyond its market capitalization. Chokepoints becomes operational when the exact network node, legal authority, target dependence, coalition, and credible escape route are written down explicitly.

For the Chokepoints section “Semiconductors reveal the difference between market share and chokepoint control,” monitor network dependence before headline sanctions outcomes. Reserve composition, correspondent-bank access, export-license exposure, coalition breadth, and evasion cost indicate whether leverage is strengthening or decaying.

Overuse is the central strategic risk

The U.S. Treasury’s own 2021 sanctions review warned that digital currencies, alternative payment systems, and reduced use of the dollar could erode sanctions effectiveness. That is an institutional admission that coercive power can be overused.

A chokepoint is strongest when counterparties still want access. If policy makes exclusion feel routine or arbitrary, firms and governments gain an incentive to invest in alternatives before they are personally targeted. For Chokepoints, that evidence changes the estimate of replaceability: a network node becomes coercive power only while the target cannot move transactions, technology, or trade elsewhere at tolerable cost.

Restraint does not mean passivity. It means matching the tool to a clearly defined national-security objective and coordinating with allies so the cost of avoidance remains high. In Chokepoints, the counterfactual must separate visible economic pain from evidence that the target would otherwise have chosen a different political course.

Executives face an equivalent problem with platform power. Extract too much from a dependent partner and the partner funds a workaround. Sustainable leverage often requires leaving enough surplus for the network to remain attractive. Chokepoints becomes operational when the exact network node, legal authority, target dependence, coalition, and credible escape route are written down explicitly.

For the Chokepoints section “Overuse is the central strategic risk,” monitor network dependence before headline sanctions outcomes. Reserve composition, correspondent-bank access, export-license exposure, coalition breadth, and evasion cost indicate whether leverage is strengthening or decaying.

Allies multiply leverage and legitimacy

Fishman’s historical cases repeatedly show that sanctions are more powerful when major allied economies participate. Coordination expands the controlled network and reduces opportunities for simple substitution.

Alliance management also constrains policy. Partners have different exposure to energy, trade, banks, and domestic constituencies, so a theoretically maximal sanction may be politically impossible. For Chokepoints, that evidence changes the estimate of replaceability: a network node becomes coercive power only while the target cannot move transactions, technology, or trade elsewhere at tolerable cost.

Unilateral action can still matter where jurisdiction is uniquely concentrated, but it increases evasion incentives and diplomatic costs. In Chokepoints, the counterfactual must separate visible economic pain from evidence that the target would otherwise have chosen a different political course.

Corporate risk teams should track allied alignment, not just U.S. headlines. A measure supported by the EU, UK, Japan, and other advanced economies is operationally different from a restriction that major partners resist. Chokepoints becomes operational when the exact network node, legal authority, target dependence, coalition, and credible escape route are written down explicitly.

For the Chokepoints section “Allies multiply leverage and legitimacy,” monitor network dependence before headline sanctions outcomes. Reserve composition, correspondent-bank access, export-license exposure, coalition breadth, and evasion cost indicate whether leverage is strengthening or decaying.

Economic warfare changes corporate strategy even before sanctions arrive

Once governments treat technology, finance, data, and supply chains as security assets, companies cannot assume geopolitical neutrality. Investment reviews, export licenses, sanctions screening, procurement rules, and industrial subsidies all shape strategic options.

The cost appears before any enforcement action: duplicate suppliers, localized data, compliance teams, inventory buffers, and country-specific technology stacks increase operating complexity. For Chokepoints, that evidence changes the estimate of replaceability: a network node becomes coercive power only while the target cannot move transactions, technology, or trade elsewhere at tolerable cost.

Those costs can look inefficient in a spreadsheet built for a frictionless world. They may still be rational insurance in a fragmented one. In Chokepoints, the counterfactual must separate visible economic pain from evidence that the target would otherwise have chosen a different political course.

CEOs should maintain a geopolitical balance sheet: which revenues depend on one jurisdiction, which assets can be frozen, which suppliers can be licensed away, and how much capital is required to create a credible alternative. Chokepoints becomes operational when the exact network node, legal authority, target dependence, coalition, and credible escape route are written down explicitly.

For the Chokepoints section “Economic warfare changes corporate strategy even before sanctions arrive,” monitor network dependence before headline sanctions outcomes. Reserve composition, correspondent-bank access, export-license exposure, coalition breadth, and evasion cost indicate whether leverage is strengthening or decaying.

Verdict: Chokepoints is a manual for seeing hidden power in economic networks

Chokepoints succeeds because it explains why modern economic coercion works without pretending it is omnipotent. Networks create leverage, but every use of leverage changes the network.

The current dollar data reinforce Fishman’s point that U.S. financial centrality remains substantial. Treasury’s own review reinforces his caution that maintaining that centrality requires disciplined use of sanctions and cooperation with allies. For Chokepoints, that evidence changes the estimate of replaceability: a network node becomes coercive power only while the target cannot move transactions, technology, or trade elsewhere at tolerable cost.

The book is strongest on mechanisms and case history. Readers should remain skeptical of any policy argument that jumps from ‘we can impose cost’ to ‘the target will concede.’ Those are different claims. In Chokepoints, the counterfactual must separate visible economic pain from evidence that the target would otherwise have chosen a different political course.

For investors and operators, the transferable insight is immediate: dependency is power. Find the nodes your business cannot replace quickly. Those are your real geopolitical exposures, regardless of how small they look on the income statement. Chokepoints becomes operational when the exact network node, legal authority, target dependence, coalition, and credible escape route are written down explicitly.

Who should read this book?

Chokepoints is most useful to investors, CFOs, compliance leaders, policy professionals, and executives whose businesses depend on cross-border payments, semiconductors, energy, shipping, or regulated technology.

Millionaire Lesson verdict

Chokepoints earns a strong recommendation because it reveals economic networks as instruments of power while taking adaptation seriously. It is most useful when readers separate the ability to impose cost from the harder task of achieving political objectives.

Its main limitation is the temptation to treat sanctions as a universal substitute for diplomacy or military power. Economic pressure is a tool whose result depends on objective, coalition, time horizon, and adaptation.

Final takeaway from Chokepoints: dependency is power, but exercised power creates substitution incentives. The strongest chokepoint strategy includes a plan for how long the chokepoint will remain scarce.
