Anti-Money Laundering (AML)
The legal framework and institutional procedures designed to detect, prevent, and report the processing of criminally derived funds through the financial system.
Also known as: AML, anti-money laundering, KYC/AML
Last reviewed: 10 June 2026
Anti-money laundering refers collectively to the laws, regulations, and operational controls that require financial institutions and certain other businesses (accountants, lawyers, estate agents, gambling operators) to identify customers, monitor transactions, and report suspicious activity. Key international standards are set by the Financial Action Task Force (FATF); national regulators such as the FCA in the UK and FinCEN in the US enforce compliance.
Core AML obligations include Customer Due Diligence (CDD) — verifying the identity of customers, understanding the purpose of their account, and identifying beneficial owners; Enhanced Due Diligence (EDD) for higher-risk customers; Suspicious Activity Reporting (SARs) when a firm knows or suspects that a transaction involves criminal property; and transaction monitoring for unusual patterns.
For fraud victims, AML controls are a double-edged sword: they may slow or freeze legitimate transactions, but they are also the primary bank-level mechanism for detecting and interrupting money mule flows and scam proceeds. When a mule account receives stolen funds, a well-tuned transaction monitoring system should flag the unusual receipt pattern and file a SAR, which intelligence agencies may use to trace the fraud network.
Examples
- A bank's AML transaction monitoring detects that a newly opened account received £50,000 in small instalments over 48 hours and files a Suspicious Activity Report.
- An estate agent conducting EDD asks a buyer to explain the source of funds for a cash property purchase under UK Money Laundering Regulations.
