Glossary › Bank Secrecy Act (BSA)

What is an Bank Secrecy Act (BSA) ?

The Bank Secrecy Act (BSA), enacted in 1970, is a cornerstone of U.S. anti-money laundering (AML) legislation. It requires financial institutions to keep records and file reports that could be helpful to detect and prevent money laundering, tax evasion, terrorist financing, and other financial crimes. These include Currency Transaction Reports (CTRs), Suspicious Activity Reports (SARs), and customer due diligence measures.

Within third-party risk management, the BSA is particularly relevant for organizations working with vendors or partners that handle financial transactions or sensitive customer data. TPRM programs may include screening for BSA compliance as part of onboarding or monitoring, especially in regulated sectors such as banking, payments, and financial technology. Failure to meet BSA obligations can lead to significant penalties and reputational damage.
