The Power of Modern Chokepoints
How can you coerce an adversary without troops, tanks, or ships? In this book, Edward Fishman argues that twenty-first-century power runs through invisible gateways—financial rails, legal standards, and technology supply chains—that function as modern chokepoints. If you can control the dollar’s plumbing, the insurance contracts that let tankers sail, or the tools that etch semiconductors, you can project influence globally with regulations and export licenses instead of missiles.
Fishman contends that sanctions and export controls work when they exploit these chokepoints; they fail when they are symbolic or unilateral. To understand why, you need to see the system: correspondent banking in New York and London, SWIFT messaging, maritime insurance from a handful of British P&I clubs, and irreplaceable technology from firms like ASML, Applied Materials, and TSMC. He weaves a narrative from Iran to Russia to China, showing how policy entrepreneurs inside Treasury, State, and Commerce turned this system into a strategic toolkit.
What counts as a chokepoint
A chokepoint is an essential node whose control lets you shape cross-border flows. Fishman highlights three clusters. First, currency and payments: dollar dominance, correspondent banking, CHIPS/Fedwire, and central-bank reserves. Second, financial messaging and services: SWIFT, maritime insurance, shipping brokers, and flag registries. Third, technology and supply chains: advanced semiconductors, design software, lithography, and machine tools. Control of any one—especially in coalition—turns a guideline into a global constraint. (Note: This is a structural-power update to Susan Strange’s “power of finance” and resonates with Chris Miller’s Chip War on semiconductor leverage.)
Dollar rails as leverage
Fishman shows you the math: the dollar appears in ~90% of FX trades; ~60% of reserves are in dollars; ~70% of cross-border corporate debt is dollar-denominated. If a bank loses access to dollar clearing or a correspondent account in New York, its global business seizes up. That is why fines against BNP Paribas (~$8.9B) and HSBC (~$1.9B) bent foreign compliance worldwide. The threat of losing the U.S. market—and with it, the dollar—makes private intermediaries the enforcers of public policy.
Sanctions technocrats and the Iran laboratory
After 9/11, Treasury assembled the Office of Terrorism and Financial Intelligence (TFI) as a war room for financial pressure. Stuart Levey, Adam Szubin, David Cohen, and colleagues pioneered a method: map networks, declassify enough intelligence to persuade CEOs, and use credible penalties to make “voluntary” de-risking the rational choice. Iran became the proof of concept—from CISADA to escrow accounts that kept oil flowing while trapping Iran’s cash abroad. This was financial engineering as statecraft, not a blunt embargo.
From Crimea to full-scale war
Russia forced an upgrade. In 2014, Dan Fried, Victoria Nuland, and Daleep Singh crafted a “scalpel” of sectoral measures to constrict refinancing and advanced oil technology without detonating Europe’s economy. MH17’s tragedy broke EU resistance; the ruble’s plunge—compounded by an oil price collapse—showed timing matters. In 2022, the coalition vaulted to a new rung: immobilizing the Central Bank of Russia’s reserves, removing key banks from SWIFT access, and launching a price cap on Russian oil enforced by a cartel of service providers.
Tech controls and the chip battlefield
Export controls matured into a coequal pillar. ZTE’s denial order proved that shutting off U.S. chips and software can halt a firm overnight. Fujian Jinhua’s blacklisting and the Foreign Direct Product Rule (FDPR) extended U.S. reach through allied supply chains: if a product is made with U.S. tools or IP, Washington can condition its sale. Coordinating with the Netherlands and Japan to limit ASML and Tokyo Electron machinery transformed chokepoint theory into global practice.
Politics, coalitions, and backfill
Sanctions are political operations. Congress often plays bad cop (ILSA/ISA, CISADA, Menendez–Kirk), allies fear collateral damage, and markets look for backfill when firms exit. Fishman shows how diplomacy, waivers, and staging—paired with private-sector risk aversion—build staying power. He also charts countermoves: Russia’s SPFS and Mir, China’s CIPS and stockpiles, BRICS expansion, and a scramble for “economic security” and friendshoring.
Why this matters to you
If you run a business, invest, or advise policymakers, this playbook is your map. You learn where leverage actually lives (banks, insurers, fabs), how to calibrate pressure (scalpels before sledgehammers), and why market psychology multiplies legal authority. You also see the costs: humanitarian spillovers in Iran, price spikes in energy, and long-term questions about the dollar’s legitimacy when central-bank assets become sanctionable. Fishman’s conclusion is sober: economic power can deter and degrade, but it demands coalitions, enforcement muscle, and public willingness to absorb trade-offs.
Key idea
Modern chokepoints let you convert regulations into strategic effects—if you align law, intelligence, allies, and private intermediaries to do the work of enforcement.
