OFAC Sanctions Law
The Office of Foreign Assets Control (OFAC) administers the most powerful economic coercion toolkit in the world — over 30 active sanctions programs targeting countries, entities, and individuals. OFAC sanctions are not symbolic: violating them is a federal crime. The legal architecture draws on IEEPA, the Trading with the Enemy Act, the International Emergency Economic Powers Act, and dozens of program-specific statutes. Understanding OFAC is essential to understanding how the US projects power without deploying military force.
Primary Text
50 U.S.C. § 1701 et seq. (IEEPA); 22 U.S.C. § 2370“Any authority granted to the President by section 1702 of this title may be exercised to deal with any unusual and extraordinary threat, which has its source in whole or substantial part outside the United States, to the national security, foreign policy, or economy of the United States, if the President declares a national emergency with respect to such threat. (50 U.S.C. § 1701)”
What It Means
OFAC — the Office of Foreign Assets Control within the US Treasury Department — administers sanctions that freeze assets, block transactions, and prohibit virtually all commerce with designated targets. As of 2025, OFAC maintains over 30 distinct sanctions programs covering countries (Iran, Russia, North Korea, Cuba, Venezuela, Syria), geographic regions (Balkans, Transnational Criminal Organizations), and individuals and entities from narcotics traffickers to weapons proliferators. OFAC's Specially Designated Nationals (SDN) list contains thousands of names — appearing on it can effectively cut an individual or entity off from the dollar-based global financial system. The legal basis for most programs is IEEPA (50 U.S.C. § 1701–1707), which requires the President to declare a national emergency involving an unusual foreign threat before exercising sanctions authority.
The penalties for OFAC violations are severe. Civil penalties can reach $1 million per transaction or twice the value of the transaction, whichever is greater, with no intent requirement — strict liability applies for some violations. Criminal penalties reach $1 million and 20 years imprisonment per willful violation. OFAC has assessed record penalties against major financial institutions: BNP Paribas paid $8.9 billion in 2014 for processing dollar-denominated transactions for sanctioned Sudan, Iran, and Cuba. HSBC, Standard Chartered, ABN AMRO, and dozens of other global banks have paid billions in OFAC settlements. The penalty regime creates powerful incentives for over-compliance — banks routinely decline transactions that have any possible sanctions nexus rather than risk investigation.
Secondary sanctions are OFAC's most legally contested tool. Traditional sanctions target the designated party's assets and transactions with US persons. Secondary sanctions threaten to sanction non-US persons who do business with the primary target — even in transactions that never touch the United States. The Countering America's Adversaries Through Sanctions Act (CAATSA, 2017) applied secondary sanctions to any entity doing significant business with Russia's defense sector, creating the threat that even European allies could face sanctions for legitimate commercial relationships. Secondary sanctions have been criticized as extraterritorial overreach incompatible with international law — and European governments have enacted 'blocking statutes' attempting to counteract their effect — but their deterrent impact on global business is undeniable.
Real-World Application
The Russia sanctions imposed after the February 2022 invasion of Ukraine represent the largest OFAC program in history. The US, EU, UK, and allied governments coordinated to impose sanctions freezing approximately $300 billion in Russian central bank assets, blocking major Russian banks from SWIFT, sanctioning hundreds of Russian officials and oligarchs, and imposing comprehensive export controls. The OFAC SDN list additions included previously untouchable figures at the apex of Russia's financial system. The sanctions package demonstrated both the unprecedented reach of coordinated Western economic warfare and its limits: Russia absorbed the initial shock, the ruble recovered, and commodity revenues continued flowing through non-sanctioned channels. The Russia sanctions remain the most important real-world test of OFAC's economic coercion toolkit.
