Stop Fentanyl Money Laundering Act of 2025

The Stop Fentanyl Money Laundering Act of 2025 would give the Department of the Treasury expanded powers to restrict financial activities linked to international fentanyl and narcotics distribution. If Treasury determines that a foreign financial institution, specific types of transactions, or certain accounts are primarily used for money laundering related to drug trafficking, the department could require U.S. financial institutions to implement special measures. These measures could include mandatory reporting of financial transactions involving those entities or activities.

The bill would also require the Financial Crimes Enforcement Network (FinCEN), a Treasury bureau that combats financial crimes, to issue guidance to banks and financial institutions. FinCEN would need to provide advisories on identifying money laundering schemes originating from China that facilitate fentanyl trafficking, as well as guidance on how to file reports about suspected narcotics trafficking by international criminal organizations. The practical effect would be stronger coordination between the government and financial institutions to track and block money flows supporting the fentanyl trade.
