Summary

The Bank Secrecy Act (BSA), formally the Currency and Foreign Transactions Reporting Act of 1970, is a foundational United States anti-money laundering (AML) law. It mandates that financial institutions assist government agencies in detecting and preventing financial crimes by maintaining records of cash purchases and reporting suspicious activities. Key requirements include filing Currency Transaction Reports (CTRs) for daily aggregate cash transactions exceeding $10,000 and Suspicious Activity Reports (SARs) for transactions suggesting money laundering or tax evasion. The act has been significantly expanded by subsequent legislation, such as the USA PATRIOT Act of 2001, which introduced Customer Identification Programs (CIP). In recent legal history, the BSA was the central focus of a major enforcement action against Binance and its founder, Changpeng Zhao (CZ), who pleaded guilty to violating the act due to inadequate KYC/AML protocols and failure to register as a financial institution, resulting in a $4 billion fine and a four-month prison sentence.

Bank Secrecy Act

The Bank Secrecy Act of 1970 (BSA), also known as the Currency and Foreign Transactions Reporting Act, is a U.S. law requiring financial institutions in the United States to assist U.S. government agencies in detecting and preventing money laundering. Specifically, the act requires financial institutions to keep records of cash purchases of negotiable instruments, file reports if the daily aggregate exceeds $10,000, and report suspicious activity that may signify money laundering, tax evasion, or other criminal activities. The BSA is sometimes referred to as an anti-money laundering law (AML) or jointly as BSA/AML.

The BSA authorizes the Department of the Treasury to impose reporting and other requirements on financial institutions and other businesses to help detect and prevent money laundering. Specifically, the regulations implementing the BSA require financial institutions to, among other things, keep records of cash purchases of negotiable instruments, file reports of cash transactions exceeding $10,000 (daily aggregate amount), and to report suspicious activity that might signify money laundering, tax evasion, or other criminal activities.

[...] Congress passed the Bank Secrecy Act (BSA) in 1970 as the first laws to fight money laundering in the United States. The BSA requires businesses to keep records and file reports that are determined to have a high degree of usefulness in criminal, tax, or regulatory investigations, risk assessments, or proceedings; or in intelligence or counterintelligence activities, including analysis, to protect against terrorism. The documents filed by businesses under the BSA requirements are heavily used by law enforcement agencies, both domestic and international to identify, detect and deter money laundering whether it is in furtherance of a criminal enterprise, terrorism, tax evasion or other unlawful activity. [...] A financial institution must verify and record the name and address of the individual conducting the transaction, as well as record the identity, account number, and the social security or taxpayer identification number of any person on whose behalf such transaction is to be effected prior to concluding the transaction. ## Suspicious Activity Report (SAR) A financial institution must file FinCEN Form 111, Suspicious Activity Report on any transaction if the transaction is conducted or attempted by, at, or through the financial institution and involves or aggregates at least $2,000 for a money services business and $5,000 for a bank, credit union, or casino, and the financial institution knows, suspects, or has reason to suspect that the transaction or pattern of transactions:

    A suspicious activity report (SAR) must report any cash transaction where the customer seems to be trying to avoid BSA reporting requirements by not filing CTR or monetary instrument log (MIL), for example. A SAR must also be filed if the customer's actions suggest that they are laundering money or otherwise violating federal criminal laws and committing wire transfer fraud, check fraud, or mysterious disappearances. These reports are filed with FinCEN and are identified as Treasury Department Form 90-22.47 and OCC Form 8010-9, 8010-1. This requirement and its accompanying implied gag order was added by the Annunzio-Wylie Anti-Money Laundering Act § 1517(b) (part of the Housing and Community Development Act of 1992, Pub. L. 102–550, 106 Stat. 3762, 4060). [...] U.S. citizens and residents with a financial interest in or authority over foreign bank accounts or "foreign financial accounts" with an aggregate value of $10,000 or more are required to file a Foreign Bank Account Report (FBAR) with the U.S. Treasury by October 15 every year. It is identified as FinCEN Form 114 (formerly Treasury Department Form 90-22.1). Additionally, they must report the interest or dividend income from the accounts on Schedule B of the Form 1040 tax form and, if a higher threshold is exceeded, also report the amounts and interest on Form 8938. Proponents of FBAR argue that it helps the United States deter financial crimes and encourage whistle-blowing for financial crimes, while critics argue that FBAR wastes time and money, "perversely discouraging compliance" [...] The statute has been amended several times, including provisions in Title III of the USA PATRIOT Act, which amended the BSA to require financial institutions to establish anti-money-laundering programs by establishing internal policies, procedures, and controls, designating compliance officers, providing ongoing employee training, and testing their programs through independent audits. There was an attempt to include another amendment in 2018, called the Illicit Arts and Antiquities Trafficking Prevention Act (IAATP). As the name implies, its aim was to restrict illegal trafficking of art in the United States which has the highest rates of money laundering in the world. It was not passed in the United States House of Representatives. This was because the aim of the IAATP did not directly
