Taylor Force Martyr Payment Prevention Act of 2023

This bill amends U.S. financial sanctions law to require the Treasury Secretary to specifically consider whether foreign banks knowingly provide banking services (including personal accounts) to entities designated under the Taylor Force Act, which targets groups that murder U.S. citizens. It directs Treasury to designate as "of primary money laundering concern" foreign banks that facilitate terrorism payments, particularly those using U.S. correspondent accounts. The law adds two new factors for Treasury to evaluate: (1) whether a bank knowingly serves entities listed in the Taylor Force Act regulations, and (2) whether the bank’s accounts or transactions help fund acts of terrorism. This directly affects foreign financial institutions operating in the U.S. financial system that may inadvertently or intentionally support terrorist organizations.
