The Office of Foreign Assets Control (OFAC) was established in 1950. The entity acts as an agency of the United States Department of the Treasury. OFAC’s objective is to impose sanctions on entities that pose a threat to U.S. national security. OFAC seeks to detect targeted entities, restrict illicit activity, and improve national and international security through administering and executing economic sanctions programs. OFAC is in charge of enforcing compliance with US sanctions laws and regulations, as well as maintaining a list of specially designated people and banned individuals.
