Which organization maintains the blocked person's list of specially designated nationals?

The organization that maintains the blocked person's list of specially designated nationals is the Department of Treasury. This list is part of the Office of Foreign Assets Control (OFAC), which operates under the Department of Treasury. The purpose of this list is to identify and block the assets of individuals and entities that are involved in activities such as terrorism, drug trafficking, or the proliferation of weapons of mass destruction. By maintaining this list, the Department of Treasury helps to enforce economic and trade sanctions based on U.S. foreign policy and national security goals.

The role of the Department of Treasury is crucial in combating financial crimes and ensuring compliance with U.S. laws relating to sanctions and financial transparency. This duty is not carried out by organizations like HUD, FDIC, or CFPB, which focus on housing, banking regulation, and consumer financial protections, respectively. Therefore, the Department of Treasury's responsibility in this context highlights its central role in national security measures and protecting the integrity of financial systems.
