United States sanctions are financial and trade restrictions imposed against individuals, entities, and jurisdictions whose actions contradict U.S. foreign policy or national security goals. Financial sanctions are primarily administered by the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC), while export controls are primarily administered by the U.S. Department of Commerce's Bureau of Industry and Security (BIS).
Restrictions against sanctioned targets vary in severity depending on the justification behind the sanction, and the legal authorities behind the sanctions action. Comprehensive sanctions are currently in place targeting Cuba, Iran, North Korea, Russia, Syria, and certain conflict regions of Ukraine, which heavily restrict nearly all trade and financial transactions between U.S. persons and those regions. Targeted sanctions specifically target certain individuals or entities that engage in activities that are contrary to U.S. foreign policy or national security goals, rather than an entire country. The U.S. also implements "secondary sanctions", which risk a sanctions designation against a non-U.S. person who transacts with sanctioned parties in violation of U.S. sanctions law, even if no U.S.-nexus existed for the transaction.
The United States has imposed two-thirds of the world's sanctions since the 1990s.[1] In 2024, the Washington Post said that the United States imposed "three times as many sanctions as any other country or international body, targeting a third of all nations with some kind of financial penalty on people, properties or organizations".[2]
