WASHINGTON (AP) — The Treasury Department wants U.S. banks and other financial institutions to monitor for suspected Iranian money laundering networks that use their funds to smuggle sanctioned oil through shell companies and crypto networks. The move, which effectively deputizes the global financial system to help disrupt Iran’s sanctions-evasion infrastructure, comes as the U.S. and Iran reached another impasse over how to end their war while their ceasefire has grown increasingly shaky.
