Treasury Targets Iran’s Exchange Houses in Aggressive Sanctions Push

*TL;DR Treasury Secretary Scott Bessent labels Iran the “head of the snake” for global terrorism and announces sanctions on more than 1,000 Iran‑linked individuals, vessels and exchange houses that move billions of dollars of oil revenue.

Context The U.S. Treasury’s Office of Foreign Assets Control (OFAC) has intensified its campaign against Iran’s financial network. Since February 2025, OFAC has added over 1,000 Iran‑related parties to its sanctions list, including exchange houses that convert oil sale proceeds from Chinese yuan into other currencies.

Key Facts - Treasury Secretary Scott Bessent warned that Iran “is the head of the snake for global terrorism” and that the Treasury is using “Economic Fury” to sever the Iranian military’s financial lifelines. - The latest designations target Opal Exchange, Radin Exchange and Tahayyori Guarantee Society (also known as Arz Iran Exchange), plus their owners and associates. - Iranian exchange houses handle billions of dollars in foreign‑currency transactions each year, primarily converting oil revenues paid in yuan into currencies usable by Iran’s military, partners and proxies. - OFAC identified individuals such as Pedram Pirouzan, Hossein Mohammad Rezaei, Masoud Mohammad Rezaei, Nasser Ghasemi Rad and Ehsan Tahayyori, many of whom used citizenship from Dominica or Saint Kitts and Nevis to hide Iranian ties. - Front companies registered in the United Arab Emirates and other jurisdictions facilitated transactions worth hundreds of millions of dollars on behalf of sanctioned Iranian persons. - The Treasury estimates Iran’s shadow banking networks move tens of billions of dollars in trade annually, much of it linked to overseas oil and petrochemical sales.

What It Means The sanctions aim to cut off the flow of oil money that funds Iran’s regional proxies and weapons programs. By targeting exchange houses that convert yuan‑denominated oil revenue, the Treasury seeks to make it harder for Tehran to access hard currency for procurement and payments. The designation of over 1,000 entities signals a broadening of the U.S. strategy from direct sanctions on Iranian officials to the financial infrastructure that sustains the regime’s illicit activities.

Watch for how Iran’s shadow banking network adapts, and whether additional sanctions will extend to banks and fintech platforms that facilitate the remaining currency conversions.
