Types of Suspicious Activities or Transactions
Under 12 CFR 21.11, national banks are required to report known or suspected criminal offenses, at specified thresholds, or transactions over $5,000 that they suspect involve money laundering or violate the Bank Secrecy Act.
The $10,000 threshold was created as part of the Bank Secrecy Act, passed by Congress in 1970, and adjusted with the Patriot Act in 2002. The law is an effort to curb money laundering and other illegal activities. The threshold also includes withdrawals of more than $10,000.
