The U.S. dollar and the institutions built around it — SWIFT, the WTO, the IMF — are not just economic infrastructure. They are tools of geopolitical power that can be deployed, and have been, as weapons.

The global financial system's infrastructure — SWIFT for payment messaging, the WTO for trade rules, dollar-denominated commodity markets, and correspondent banking networks — was built as neutral plumbing for the global economy. It has increasingly been weaponized as a tool of geopolitical coercion, most aggressively by the United States and its allies, and most consequentially against Russia following the 2022 invasion of Ukraine.
This weaponization has produced a significant strategic shift: countries that observe these tools being deployed against adversaries are investing in alternative infrastructure to reduce their own exposure, creating a slow fragmentation of the previously unified global financial system.
SWIFT (Society for Worldwide Interbank Financial Telecommunication) is a messaging network that facilitates approximately 40 million financial messages daily between 11,000+ financial institutions in 200+ countries. It is not a payment system itself — it is the secure messaging layer that enables payment orders to move between banks. Without SWIFT access, a bank cannot easily communicate payment instructions to foreign counterparties, effectively isolating it from the international financial system.
SWIFT exclusion was first used meaningfully against Iran in 2012, cutting Iranian banks off from international dollar transactions as part of nuclear program sanctions. The effect was severe: Iranian oil exports dropped sharply, the rial collapsed, and economic pressure mounted. The Iran precedent demonstrated SWIFT exclusion's effectiveness and its limits — Iran found workarounds through informal hawala networks, Chinese and Turkish intermediaries, and barter arrangements for oil.
In March 2022, seven major Russian banks were excluded from SWIFT following Russia's invasion of Ukraine. The impact was significant but incomplete: Sberbank (Russia's largest bank) was initially excluded while Gazprombank (which handled European energy payments) was exempted to avoid disrupting European gas imports. Russia developed SPFS (its own payment messaging system) as a partial alternative, though it covers only a fraction of SWIFT's global reach.
The World Trade Organization provides the rules-based framework for international trade — binding tariff schedules, dispute resolution, and the legal framework within which trade policy must operate. WTO membership means committing to Most Favored Nation treatment (tariff rates applied to all members equally) and accepting binding dispute resolution.
The U.S.-China trade conflict has severely strained the WTO system. The U.S. imposed Section 301 tariffs on $360 billion of Chinese goods, arguing China's IP theft and forced technology transfer justified departure from WTO rules. China filed WTO complaints and won — but the U.S. refused to comply, arguing the WTO dispute system couldn't address the structural issues at stake. The WTO's appellate body has been effectively paralyzed since 2019 after the U.S. blocked the appointment of new judges, leaving dispute resolution incomplete.
The practical consequence: the rules-based trading system is increasingly governed by power dynamics and bilateral negotiations rather than the multilateral legal framework built since 1947. This shift advantages large economies (which have leverage in bilateral negotiations) and disadvantages small ones (which depended on multilateral rules for protection against powerful trading partners).
