The "Combatting Money Laundering in Cyber Crime Act of 2025" significantly expands the investigative authority of the United States Secret Service to combat financial crimes. It grants the Secret Service jurisdiction over unlicensed money transmitting businesses , money laundering , and structured transactions , particularly those involving digital assets and targeting all financial institutions, not just federally insured ones. The bill also extends the duration of the FinCEN Exchange program from 5 to 10 years, enhancing information sharing between law enforcement and financial institutions. Furthermore, it extends a related provision concerning international financial institutions under the North Korea Nuclear Sanctions and Enforcement Act. To assess effectiveness, the legislation mandates a Government Accountability Office (GAO) study within one year to evaluate law enforcement's ability to identify and deter money laundering in cybercrimes.
