History of Anti-Money Laundering Laws

Money laundering is the process of making illegally-gained proceeds (i.e. "dirty money") appear legal (i.e. "clean"). Typically, it involves three steps: placement, layering and integration. First, the illegitimate funds are furtively introduced into the legitimate financial system. Then, the money is moved around to create confusion, sometimes by wiring or transferring through numerous accounts. Finally, it is integrated into the financial system through additional transactions until the "dirty money" appears "clean." Money laundering can facilitate crimes such as drug trafficking and terrorism, and can adversely impact the global economy.


In its mission to "safeguard the financial system from the abuses of financial crime, including terrorist financing, money laundering and other illicit activity," the Financial Crimes Enforcement Network acts as the designated administrator of the Bank Secrecy Act (BSA). The BSA was established in 1970 and has become one of the most important tools in the fight against money laundering. Since then, numerous other laws have enhanced and amended the BSA to provide law enforcement and regulatory agencies with the most effective tools to combat money laundering. An index of anti-money laundering laws since 1970 with their respective requirements and goals are listed below in chronological order.
