An OFAC enforcement action is the formal process by which the U.S. Treasury's Office of Foreign Assets Control investigates and penalizes violations of U.S. economic sanctions programs. OFAC administers sanctions authorized under statutes such as the International Emergency Economic Powers Act (IEEPA), the Trading with the Enemy Act (TWEA), and various country- or program-specific laws, along with executive orders issued by the President.
Enforcement actions typically arise from violations involving prohibited transactions with sanctioned jurisdictions (e.g., Iran, Cuba, North Korea, Syria, Russia), blocked persons on the Specially Designated Nationals and Blocked Persons (SDN) List, or sectoral sanctions targets. Common triggers include voluntary self-disclosures by companies, suspicious activity reports, whistleblower tips, and referrals from other agencies.
OFAC's response options range, in increasing severity, from:
- No Action Letters or cautionary letters
- Findings of Violation (public but non-monetary)
- Civil monetary penalties (settled via consent or imposed)
- Referral for criminal prosecution to the Department of Justice
Penalty amounts are calculated using OFAC's Economic Sanctions Enforcement Guidelines (codified at 31 C.F.R. Part 501, Appendix A), which weigh factors such as willfulness, harm to sanctions objectives, the violator's commercial sophistication, compliance program quality, and cooperation. Statutory maximums under IEEPA reach the greater of roughly $300,000 per violation (adjusted for inflation) or twice the value of the underlying transaction.
High-profile settlements have included BNP Paribas in 2014 (nearly $9 billion in combined penalties for sanctions-evading dollar-clearing), Standard Chartered, HSBC, ZTE, and tech firms such as Microsoft in 2023. OFAC publishes settlement summaries in its Recent Actions feed, which compliance officers treat as informal precedent.
For non-U.S. actors, OFAC asserts jurisdiction whenever transactions touch the U.S. financial system, involve U.S.-origin goods, or implicate U.S. persons—making sanctions enforcement a significant extraterritorial tool of American foreign policy.
Example
In 2014, OFAC and other U.S. authorities reached a roughly $8.9 billion settlement with BNP Paribas for processing dollar transactions involving Sudan, Iran, and Cuba in violation of U.S. sanctions.
