US Treasury Orders Banks to Watch for Iranian Money Laundering Schemes

WASHINGTON — Federal officials are instructing American banks and financial institutions to keep watch for Iranian money laundering operations that utilize shell corporations and digital currency networks to illegally transport sanctioned petroleum products.

This directive essentially enlists the worldwide banking system to help dismantle Iran’s sanctions-dodging infrastructure, occurring as US-Iran relations have reached another deadlock regarding ending their conflict while their current truce becomes more fragile.

On Monday, President Donald Trump declared the Iranian ceasefire is on “life support” following his dismissal of Tehran’s most recent peace proposal.

The Trump administration is urging financial institutions to identify specific clients who might be washing money for Iran’s Revolutionary Guard — this includes recently established businesses transferring exceptionally large sums, organizations that channel payments through numerous middlemen, or deals linked to Iranian cryptocurrency companies, along with other warning signs.

Within the US effort to track Iranian petroleum sales, banks receive instructions to look for oil marked as “Malaysian blend” to hide its Iranian source, absent or fake transport paperwork, or vessel-to-vessel oil transfers that mask cargo origins.

A Monday report from Treasury’s Financial Crimes Enforcement Network indicates that petroleum companies tied to Iran handled approximately $4 billion in deals during 2024.

Additionally, multiple shipping firms headquartered in Iraq, the United Arab Emirates, and Hong Kong — all linked to moving sanctioned Iranian petroleum — moved roughly $707 million through American bank accounts in 2024.

Beyond conducting bombing operations in Iran, the Trump administration has shifted toward an economically-centered strategy designed to pressure Tehran into surrender through sanctions and threats of secondary penalties against Iran’s partners.

Last April, Treasury delivered correspondence to financial organizations in China, Hong Kong, the UAE, and Oman warning of potential secondary sanctions for conducting Iranian business and claiming these nations permit Iranian illegal operations to pass through their banking systems.
