US and allied rules that freeze assets and bar targets from the dollar-based banking system.
See it on the Money & Finance map →How it works
Nearly all dollar payments clear through US banks, so the Treasury's Office of Foreign Assets Control (OFAC) can block anyone it lists and penalize foreign banks that deal with them. The main legal basis is the 1977 International Emergency Economic Powers Act. After Russia invaded Ukraine in 2022, the G7 and EU froze roughly $300 billion of Russia's central-bank reserves, mostly at Euroclear in Belgium. In 2024 the G7 used interest earned on them to back a $50 billion loan to Ukraine.
Why it matters
They let Washington punish without military force, but each use gives other countries a reason to hold fewer dollars.
Facts, rules and data
OFAC's public sanctions lists, presidential executive orders, EU Council regulations and record bank penalties, such as BNP Paribas's $8.9 billion in 2014.
Debates and risks
How well sanctions change behavior is debated; studies find mixed results, and Russia's economy adapted more than many expected.

▸Financial sanctions and 'weaponizing' the dollar can cut banks off from SWIFT: the bank messaging networkFact, law or data
The connection
Banks send cross-border payment orders as SWIFT messages, so a bank cut off from SWIFT struggles to send or receive international payments, slowing a country's trade. SWIFT is a Belgian cooperative under EU law, so disconnections come through EU regulations, often after US pressure. The US's stronger tool is dollar clearing: OFAC can bar US banks from dealing with targets.
When and why
Iranian banks were cut off in March 2012 and again in 2018; seven Russian banks in March 2022, with Sberbank added in June 2022.
How we know
EU Council regulations naming the banks, and SWIFT's own public statements confirming it complied.
Debates and risks
How much damage disconnection does when targets reroute through Russia's SPFS, China's CIPS or third-country banks is debated.
▸Financial sanctions and 'weaponizing' the dollar are enforced by OFAC: Office of Foreign Assets ControlFact, law or data
The connection
The President declares a national emergency under the 1977 IEEPA law and issues an executive order; OFAC then names targets, publishes rules and licenses exceptions. US banks must freeze targets' assets and block their payments. Foreign banks usually comply too, because losing access to US dollar accounts would cripple them.
When and why
Since the Korean War freeze of December 1950; recent waves targeted Iran, North Korea and, after February 2022, Russia, with thousands of new designations.
How we know
OFAC's published SDN list and penalty notices; BNP Paribas's $8.9 billion settlement with US authorities in 2014; Binance's 2023 settlement, which included OFAC violations.
Debates and risks
Whether 'secondary sanctions' on foreign firms are legitimate under international law is disputed, and evasion through shadow oil tankers and front companies is widespread.
▸Financial sanctions and 'weaponizing' the dollar accelerate talk of De-dollarization and BRICS alternativesExperts disagree
The connection
When the dollar system is used to punish, potential targets see risk in holding dollars. The 2022 freeze of about $300 billion of Russia's central-bank reserves was a turning point: assets assumed safe became unusable overnight. Russia, China and others expanded local-currency trade, alternative payment systems and gold buying in response.
When and why
After Russia's February 2022 invasion of Ukraine; Russia–China trade shifted mostly to rubles and yuan by 2023–24.
How solid is the link?
Russian officials have said over 90% of Russia–China trade settles in rubles and yuan; central-bank surveys cite sanctions as a reason to buy gold.
Debates and risks
Whether talk becomes action: the dollar's share of currency trading and trade invoicing has barely changed since 2022.
▸Correspondent banking: nostro and vostro accounts is the choke point for Financial sanctions and 'weaponizing' the dollarFact, law or data
The connection
Foreign banks need US correspondent accounts to pay in dollars, and those US banks must block payments involving anyone on the Treasury's sanctions lists. Cutting a foreign bank off from correspondent access shuts it out of most dollar trade, so the threat reaches banks far beyond US borders.
When and why
Enforced by Treasury's OFAC; BNP Paribas agreed to pay about $8.9 billion in 2014 for moving dollars through US banks for Sudan, Iran and Cuba.
How we know
OFAC regulations and enforcement actions, the BNP Paribas guilty plea, and Treasury's 2005 action against Banco Delta Asia over North Korean funds.
Debates and risks
Whether heavy use of this choke point speeds 'de-dollarization' as targets build alternatives, or shows the dollar system is too useful to leave.
▸Oil paid in yuan: Russia, Iran and the Saudi talks grew as Russia and Iran dodged Financial sanctions and 'weaponizing' the dollarFact, law or data
The connection
US and EU sanctions cut Russian and Iranian banks off from dollar and euro payments and froze Russia's central-bank reserves. Selling oil for yuan to China, through Chinese banks outside US reach, became their workaround. US threats since late 2023 to sanction foreign banks that help Russia have slowed some payments.
When and why
Iran since US sanctions returned in 2018; Russia since 2022.
How we know
OFAC actions, Treasury statements, and reports of delayed Russia–China payments in 2024.
Debates and risks
Whether sanctions are speeding a lasting move away from the dollar, a cost critics say Washington underestimates.
