The U.S. Treasury Department sanctioned two networks tied to the Sinaloa Cartel on May 20, 2026, citing fentanyl trafficking and the conversion of illicit proceeds into cryptocurrency. The action freezes U.S.-based assets and bars U.S. persons from transacting with the designated parties, extending sanctions pressure directly into on-chain financial flows.
