WASHINGTON — The Treasury Department has directed U.S. banks and other financial institutions to actively monitor for suspected Iranian money laundering networks. These networks are reportedly using shell companies and cryptocurrency to facilitate the smuggling of sanctioned Iranian oil.
This directive effectively deputizes the global financial system to assist in dismantling Iran’s sanctions-evasion infrastructure. The move comes at a time of heightened tensions, with the U.S. and Iran at an impasse over ending their conflict, and a ceasefire described as increasingly fragile. President Donald Trump recently stated the Iran ceasefire is on ‘life support’ after rejecting Tehran’s latest proposal.
The Trump administration is urging banks to identify customers potentially laundering funds for Iran’s Revolutionary Guard. Key indicators include newly formed companies moving unusually large sums, firms routing payments through multiple intermediaries, and transactions linked to Iranian cryptocurrency firms.
Monitoring Sanctioned Oil Sales
As part of the U.S. initiative to track Iranian oil sales, financial institutions are also being asked to watch for specific deceptive practices. These include oil labeled as ‘Malaysian blend’ to obscure its Iranian origin, missing or falsified shipping documents, and ship-to-ship oil transfers designed to conceal cargo provenance.
Financial Activity and Sanctions Efforts
A report released by the Treasury’s Financial Crimes Enforcement Network (FinCEN) on Monday indicated that oil firms associated with Iran conducted approximately $4 billion in transactions in 2024. Furthermore, dozens of shipping companies based in Iraq, the United Arab Emirates, and Hong Kong, involved in transporting sanctioned Iranian oil, processed about $707 million through U.S. accounts during the same year.
The Trump administration’s strategy against Iran includes a significant economic focus, aiming to exert pressure through sanctions and the threat of secondary sanctions on countries allied with Tehran. In April, the Treasury Department sent letters to financial institutions in China, Hong Kong, the UAE, and Oman, warning of secondary sanctions for engaging in business with Iran and accusing these nations of enabling illicit Iranian activities through their financial systems.
