Which organization maintains a list of specially designated nationals (SDNs)?

The organization that maintains a list of specially designated nationals (SDNs) is the Office of Foreign Assets Control (OFAC). OFAC is a part of the U.S. Department of the Treasury and is responsible for enforcing economic and trade sanctions based on US foreign policy and national security goals. This includes identifying and listing individuals and entities that are considered to be involved in terrorism, narcotics trafficking, or other activities that threaten U.S. national security.

The SDN list includes individuals, groups, and entities that are subject to certain restrictions, including asset freezes and prohibition of transactions. It serves as a critical tool in the enforcement of anti-money laundering (AML) policies, as it helps financial institutions and businesses prevent inadvertently engaging with parties that have legal or reputational risks associated with them. By adhering to this list, organizations can ensure compliance with U.S. laws and regulations, thereby playing a role in the broader effort to combat money laundering and terrorist financing.

In contrast, the other organizations mentioned serve different purposes. The SDNL appears to not exist as a widely recognized institution related to sanctions. The International Association of Insurance Supervisors (IAIS) focuses on the regulation and supervision of insurance companies internationally and does not maintain lists like the SDNs. The
