A set of procedures, laws or regulations designed to stop the practice of generating income through illegal actions. In most cases money launderers hide their actions through a series of steps that make it look like money coming from illegal or unethical sources was earned legitimately.
Though anti-money-laundering laws cover only a relatively limited number of transactions and criminal behaviors, their implications are extremely far reaching. An example of AML regulations are those that require institutions issuing credit or allowing customers open accounts to complete a number of due-diligence procedures to ensure that these institutions are not aiding in money-laundering activities. The onus to perform these procedures is on the institutions, not the criminals or the government.
Anti-money laundering is a term mainly used in the finance and legal industries to describe the legal controls that require financial institutions and other regulated entities to prevent or report money laundering activities. Anti money-laundering guidelines came into prominence globally after the September 11, 2001 attacks and the subsequent enactment of the USA Patriot Act. Today, all financial institutions globally are required to monitor, investigate and report transactions of a suspicious nature to the financial intelligence unit of the central bank in the respective country. For example, a bank must perform due diligence by having proof of a customer's identity and that the use, source and destination of funds do not involve money laundering. United States federal law related to money laundering is implemented under the Bank Secrecy Act of 1970 as amended by anti-money laundering acts up to the present.
