US sanctions 35 entities in Iran shadow banking crackdown

The United States intensified economic pressure on Iran Tuesday, targeting a sprawling shadow banking network of 35 entities and individuals used to evade sanctions and simultaneously warning financial institutions of their exposure to Chinese refineries that purchase Iranian crude. The move aims to disrupt what officials called a critical financial lifeline for Iran's armed forces, contributing to a rise in oil prices already inflated by Middle East supply disruptions.

"Iran’s shadow banking system serves as a critical financial lifeline for its armed forces, enabling activities that disrupt global trade and fuel violence across the Middle East," Treasury Secretary Scott Bessent said in a statement. "Any institution that facilitates or engages with these networks is at risk of severe consequences."

The dual-pronged action pushed Brent crude futures for June up 0.47 percent to $111.78 a barrel, while U.S. West Texas Intermediate futures rose 0.57 percent to $100.50. The sanctions and advisory from the Treasury’s Office of Foreign Assets Control (OFAC) explicitly link Iran’s illicit oil sales, funneled through this network, to the funding of its military, the Islamic Revolutionary Guard Corps (IRGC), and various proxy groups.

This escalation represents the most significant US action against Iranian oil smuggling to China since attempts to restore the 2015 nuclear deal were abandoned. The targeting of so-called "tolls" paid to the IRGC for passage through the Strait of Hormuz—a chokepoint for about 20 percent of global oil supplies—directly threatens a key revenue stream for Tehran and exposes any foreign bank involved in such transactions to US penalties.

China's "Teapot" Refineries in Focus

A specific alert was issued to financial institutions regarding the sanctions risks of dealing with independent "teapot" refineries in China, primarily located in Shandong province. These smaller refiners have become central to China's oil trade with Iran, importing significant quantities of crude that is often rebranded as originating from other countries like Malaysia.

OFAC warned that banks facilitating transactions for these teapot refineries, some of which have used the US financial system for dollar-denominated trades, could face sanctions. The last major US action targeting these entities was in 2019, indicating a significant renewal of focus on this channel of Iranian oil exports.

Shadow Banking Network Targeted

Tuesday’s designations targeted key nodes in a network the Treasury says has moved tens of billions of dollars for Iran. Among those sanctioned are Farab Soroush Afagh Qeshm Company and two of its executives for their work with Iran’s Shahr Bank in facilitating oil sales.

OFAC also designated companies linked to Bank Sina, which is controlled by Iran’s Supreme Leader, and the military-affiliated Bank Sepah, a known financier of Iran’s ballistic missile program. The action seeks to sever the IRGC's access to the global financial system, which it uses to collect payments from illicit oil sales and procure components for weapons systems.
