The Treasury Department is calling on U.S. banks and financial institutions to monitor for suspected Iranian money laundering networks that use their funds to smuggle sanctioned oil through shell companies and crypto networks. This move effectively deputizes the global financial system to help disrupt Iran’s sanctions-evasion infrastructure.
Background and Context
The initiative comes as the U.S. and Iran reached another impasse over ending their war, with the ceasefire growing increasingly shaky. President Donald Trump said on Monday that the Iran ceasefire is on “life support” after he rejected Tehran’s latest proposal to end the conflict.
Key Indicators for Banks
The Trump administration is asking banks to flag certain customers who may launder funds for Iran’s Revolutionary Guard. Red flags include newly formed companies moving unusually large amounts of money, firms routing payments through multiple intermediaries, and transactions connected to Iranian crypto firms.
As part of the U.S. initiative to monitor Iranian oil sales, banks are advised to watch for oil labeled as “Malaysian blend” to disguise its Iranian origin, missing or falsified shipping documents, and ship-to-ship oil transfers that obscure the cargo’s origin.
Financial Data and Enforcement
A Treasury Financial Crimes Enforcement Network report released Monday indicates that oil firms linked to Iran conducted roughly $4 billion in transactions in 2024. Dozens of shipping companies based in Iraq, the United Arab Emirates, and Hong Kong—all connected to transporting sanctioned Iranian oil—processed about $707 million through U.S. accounts in 2024.
Alongside a bombing campaign in Iran, the Trump administration has turned toward an economic-focused effort aimed at choking Tehran into submission through sanctions and the threat of secondary sanctions on Iran's allies. In April, Treasury sent a letter to financial institutions in China, Hong Kong, the UAE, and Oman, threatening to levy secondary sanctions for doing business with Iran and accusing those countries of allowing Iranian illicit activities to flow through their financial institutions.
