Where is the list of Specially Designated Nationals (SDNs) maintained?

The Specially Designated Nationals (SDNs) list is maintained by the Office of Foreign Assets Control (OFAC), which is a division of the U.S. Department of the Treasury. OFAC's primary role is to enforce economic and trade sanctions based on U.S. foreign policy and national security goals. The SDN list specifically identifies individuals, groups, and entities that are prohibited from engaging in transactions with U.S. persons, as these designated parties are considered to pose a threat to national security, foreign policy, or economy. This makes OFAC the authoritative source for information regarding SDNs.

The other options serve different purposes in the realm of financial regulation. FinCEN manages the enforcement of anti-money laundering (AML) regulations and oversees financial institutions to prevent illicit finance but does not maintain the SDN list. FATF, the Financial Action Task Force, is an international organization that develops policies to combat money laundering and terrorist financing but does not maintain a specific SDN list. Lastly, SDNL is not a recognized entity or organization relevant to the maintenance of the SDN list.
