On June 25, 2025, the U.S. Department of Treasury’s Financial Crimes Enforcement Network (“FinCEN”) issued three orders designating two Mexico-based commercial banks—CIBanco and Intercam—and a Mexico-based brokerage firm, Vector, as being of “primary money laundering concern” in connection with their purported ties to opioid trafficking and international drug cartels. These orders, which are the first FinCEN has issued pursuant to a recently enacted fentanyl trafficking law, broadly prohibit domestic U.S. financial institutions and agencies from transferring any funds to or from the designated entities. The orders take effect 21 days after their publication in the Federal Register. Financial institutions and other companies worldwide should immediately be vigilant for potential money laundering risks relating to these entities.
