The USA PATRIOT Act is a comprehensive legislation that was enacted in 2001 to enhance the powers and tools of the US authorities to combat money laundering, terrorist financing, and other threats to the national security and the integrity of the financial system. The USA PATRIOT Act contains several provisions that affect the relationship between US banks and foreign banks that maintain correspondent accounts in the US.
One of these provisions is Section 319, which allows the US authorities to seize the funds of a foreign bank held with a US bank, if the foreign bank refuses to comply with a subpoena or a request for records related to the correspondent account. This provision is intended to prevent foreign banks from using their correspondent accounts in the US to facilitate transactions involving tainted funds, such as proceeds of crime, funds intended to support terrorism, or funds subject to sanctions or asset freezing orders. Section 319 also requires US banks to maintain records of the owners and agents of foreign banks that have correspondent accounts with them, and to terminate such accounts if requested by the US authorities.
Therefore, if a foreign bank maintains a correspondent account in the US, and the US authorities find out that the account has been used to facilitate a transaction involving tainted funds, the US authorities can seize the funds of the foreign bank held with the US bank, under the authority of the USA PATRIOT Act.

According to the Financial Action Task Force (FATF), a financial institution must take certain steps to fulfill its customer due diligence (CDD) obligations [1][2]. These steps include verifying the customer's identity, understanding the customer's business, and assessing the customer's risk profile. Additionally, the financial institution must verify that the customer is not on any sanction lists, such as the OFAC Specially Designated Nationals list. This step is important to ensure that the financial institution is not doing business with any individuals or entities that are subject to economic sanctions. Other steps include obtaining information on the intended nature of the banking relationship, securing a written declaration from the customer confirming the source of the funds, and identifying shareholders listed on the stock exchange of corporate entities holding fifty percent of the shares.
