In this article, Matteson Ellis analyzed the implications of the Trump administration's intensified enforcement efforts targeting Mexican firms – particularly the U.S. Department of the Treasury's Financial Crimes Enforcement Network (FinCEN) sanctions against three Mexican financial institutions. These sanctions prohibit U.S. financial institutions from transmitting funds to or from the designated entities. "Traditional corporate controls designed to prevent illicit payments and dealings with sanctioned entities, while playing an important role in managing these new risks, might not be sufficient," Ellis wrote. "Companies doing business in Mexico should actively assess their current controls against new risks to ensure compliance programs are effectively calibrated."
