The U. S. Department of the Treasury established the Financial Crimes Enforcement Network in 1990 to provide a government-wide multisource financial intelligence and analysis network. The organization's operation was broadened in 1994 to include regulatory responsibilities for administering the Bank Secrecy Act, one of the nation's most potent weapons for preventing corruption of the U. S. financial system. The mission of the Financial Crimes Enforcement Network is to enhance U. S. national security, deter and detect criminal activity, and safeguard financial systems from abuse by promoting transparency in the U. S. and international financial systems.
