BSA/AML regulations are designed to help identify the source, volume, and movement of currency and other monetary instruments. BSA/AML statutes require individuals, banks, and other financial institutions to file currency reports with the U.S. Department of the Treasury, properly identify persons conducting transactions, and maintain a paper trail by keeping appropriate records of financial transactions. Regulatory agencies and law enforcement networks use these records to investigate criminal, tax, and regulatory violations and, if warranted, provide evidence useful in prosecuting money laundering and other financial crimes.
