Anti-Money Laundering (AML) is is a term used in the financial industry to describe a set of procedures, laws and regulations that require financial institutions and other regulated entities to prevent, detect, and report money laundering activities.
AML regulations require institutions allowing customers to open trading accounts to complete due-diligence procedures to ensure they are not aiding in money-laundering activities. The legal responsibility to perform these procedures is on the institutions, not on the criminals or the government.
