The Department of the Treasury is an executive department of the United States federal government responsible for promoting economic growth and stability. Within the Treasury, the Financial Crimes Enforcement Network (FinCEN) is a bureau responsible for combating money laundering and other financial crimes. FinCEN provides regulations, reforms, and financial intelligence to law enforcement agencies, financial institutions, and the general public.

FinCEN also has investigative and enforcement authority to combat money laundering, terrorist financing, and other financial crimes. The agency collects, analyzes, and disseminates financial intelligence for law enforcement purposes and maintains a database of suspicious activities and transactions. FinCEN collaborates with federal agencies, state and local law enforcement, and foreign Governments to combat illicit financial activities. The agency also conducts outreach and education programs to educate financial institutions, regulators, and the public on emerging financial threats and risks. FinCEN’s mission is to safeguard the financial system from illegal activities and promote national security through financial intelligence. The agency’s work plays a crucial role in maintaining the integrity and credibility of the US financial system.
