Economic Warfare in the 21st Century: How U.S. Sanctions Shape Global Politics
When headlines flash with missile launches or troop movements, the quieter battleground of economic statecraft often goes unnoticed. Yet, as Edward Fishman argues in his latest book, the United States’ most potent geopolitical tool today is not a carrier strike group but the ability to choke off access to the dollar, advanced semiconductors, and vital energy flows. Drawing on his firsthand experience shaping sanctions policy, Fishman shows how Washington has turned financial pressure into a decisive instrument of statecraft.
Who Is Edward Fishman?
Edward Fishman served on the Iran Sanctions Team at the U.S. Department of State from 2013 to 2014. After Russia’s annexation of Crimea in 2014, he became the inaugural Russia and Europe chief in the State Department’s Office of Economic Sanctions Policy and Implementation. In these roles he helped design and execute the secondary‑sanction regime that pressured Tehran into negotiations, giving him a unique vantage point on how economic tools are deployed against adversaries ranging from Iran to Russia and China.
The Mechanics of Modern Sanctions
Fishman emphasizes that contemporary sanctions rely less on outright bans and more on controlling “bottlenecks” that sit at the heart of the global economy:
- The U.S. dollar – most international trade is invoiced in dollars; cutting off dollar access forces firms to seek costly alternatives or cease transactions.
- Advanced microchip technology – export controls on lithography equipment and design software limit rivals’ ability to produce cutting‑edge semiconductors.
- Critical energy supply chains – restrictions on investment, technology, and financing for oil and gas projects can curtail a target’s revenue streams.
By leveraging these choke points, the U.S. can generate “shockwaves” that reverberate through global markets far faster than any military maneuver.
Case Study: Iran’s Nuclear Program and the JCPOA
After the 1979 Islamic Revolution, U.S.–Iran relations deteriorated sharply, especially as Iran pursued a nuclear enrichment capability. Fishman recounts how the Office of Foreign Assets Control (OFAC) became the linchpin of U.S. pressure:
- Primary sanctions barred U.S. persons from dealing with Iranian entities.
- Secondary sanctions threatened non‑U.S. firms that facilitated Iran’s oil, banking, or shipping activities with loss of access to the U.S. financial system.
- The result was a dramatic contraction in Iran’s oil exports: from roughly 2.5 million barrels per day in 2011 to just under 1 million bpd by 2019, according to the U.S. Energy Information Administration (EIA, 2020).
- Iran’s real GDP shrank by an estimated 9.5 % in 2018, a contraction the World Bank attributes largely to sanctions (World Bank, 2019).
Facing dwindling hard‑currency reserves, Iran entered multilateral talks that produced the 2015 Joint Comprehensive Plan of Action (JCPOA). Under the agreement, the U.S. lifted nuclear‑related sanctions while Iran agreed to curb its enrichment activities, reduce its stockpile of low‑enriched uranium, and submit to enhanced IAEA monitoring. Fishman notes that the deal illustrated how economic leverage could bring a reluctant adversary to the negotiating table without firing a shot.
Applying the Lesson: Russia, China, and Beyond
The Iran experience has informed subsequent U.S. strategies:
- Russia – Following Crimea’s annexation, the Treasury’s OFAC expanded sectoral sanctions targeting energy, finance, and defense. Secondary sanctions threatened European firms participating in the Nord Stream 2 pipeline, illustrating the extraterritorial reach of dollar‑based pressure.
- China – Export controls on advanced semiconductor equipment (e.g., EUV lithography tools) aim to impede Beijing’s drive for technological self‑sufficiency. The Entity List, maintained by the Bureau of Industry and Security, now includes over 300 Chinese firms (BIS, 2024).
- Global Supply Chains – Policies such as the CHIPS Act and the Inflation Reduction Act incentivize reshoring of critical industries, reducing adversaries’ leverage over essential inputs.
These measures reflect Fishman’s thesis: control over financial, technological, and energy bottlenecks enables the United States to exert influence far beyond traditional military power.
Why This Matters for Readers
Understanding the mechanics of economic statecraft helps citizens and policymakers alike assess the costs and benefits of sanctions—not only for target states but also for allied economies and global markets. Fishman’s work, grounded in years of frontline policy experience, offers a clear, evidence‑based framework for evaluating how economic warfare shapes the modern geopolitical landscape.
