U.S. Treasury orders banks to flag Iranian money‑laundering networks exploiting crypto and shell companies
The U.S. Treasury Department issued new guidance on May 11, requiring financial institutions to monitor and flag transactions linked to suspected Iranian money‑laundering networks, according to the South China Morning Post. The directive aims to disrupt schemes that use U.S. banks to funnel proceeds from sanctioned Iranian oil sales through shell corporations and cryptocurrency platforms.
Iran has repeatedly violated UN and U.S. sanctions by covertly selling oil on the black market, using complex financial structures to evade detection. The Treasury’s Office of Foreign Assets Control (OFAC) has intensified enforcement in recent months, following a series of high‑profile indictments against Iranian front companies.
The announcement details that banks must implement “enhanced due‑diligence” protocols, including real‑time transaction monitoring, customer risk‑scoring, and reporting of suspicious activity related to known Iranian entities. OFAC Director Karen Harris told reporters, “We are leveraging the entire financial system to choke off illicit revenue streams that fund destabilizing activities.” The SCMP notes that the move dovetails with ongoing diplomatic deadlock over Iran’s nuclear program, which has stalled cease‑fire talks.
Experts suggest the guidance could have broad repercussions for the global banking sector, especially those with heavy exposure to Middle‑East trade. Dr. Samuel Liu, a finance professor at NYU, warned that “over‑compliance could strain legitimate Iranian‑U.S. trade, but failing to act risks facilitating sanctions evasion.” International banking groups have begun revising compliance manuals to align with the new policy.
Implementation will be phased over the next 90 days, with Treasury slated to publish a detailed compliance handbook in early June. Stakeholders will watch for enforcement actions, including potential civil penalties, and for any diplomatic shifts that could affect the severity of the sanctions regime.
