Under the guidelines of the BSA, the Treasury Department now requires broker-dealers to obtain and keep information relating to clients that make or receive funds transfers that involve $3,000 or more. If the transaction is a cash transaction over $10,000, the same rules apply, and a Currency Transaction Report must be filed with FinCEN. Under the USA Patriot Act, if the broker-dealer thinks that a transaction of $5,000 or more is suspect, the broker-dealer must file a suspicious activity report (SAR.)
