Bank Secrecy Act Regulations Explained
By Bonner & Partners analyst Joe Withrow
The Bank Secrecy Act (BSA) requires US financial institutions to assist federal agencies in preventing money laundering.
All financial institutions are required by law to keep records of all financial activity, including cash purchases of "negotiable instruments"—checks, money orders, etc.
These records are open to government inspection at any time. They are also subject to periodic audits by both federal and state governments.
All financial institutions must immediately file a Suspicious Activity Report (SAR) with the federal government whenever a customer engages in transactions the institutions deem strange or inconsistent with normal behavior. This is open to interpretation.
