U.S. Imposes Sanctions on 35 Iran‑linked Entities Over Shadow Banking and Terrorism Funding (April 28, 2026)

Overview The U.S. Government on April 28, 2026 announced a new round of sanctions targeting 35 entities and individuals linked to Iran’s illicit financial networks. The move aims to curb the flow of tens of billions of dollars that finance sanctions evasion and what Washington describes as Iran’s sponsorship of terrorism . Key Developments Sanctions imposed on 35 entities and individuals involved in Iran’s shadow banking sector . The Treasury’s Office of Foreign Assets Control (OFAC) warned banks that transact with Chinese “teapot” refineries could face secondary sanctions. Chinese refineries, dubbed “teapot” refineries, are alleged to pay tolls for oil shipments that transit the Strait of Hormuz . OFAC estimates the sanctioned activities involve the equivalent of tens of billions of dollars in illicit financial flows. Important Facts The designated parties are accused of facilitating money‑laundering, front‑company operations, and procurement of dual‑use technology for Iran’s nuclear and missile programmes. The “teapot” refineries are small‑scale Chinese oil‑processing units that lack full licensing, making them attractive for covert oil purchases. By threatening secondary sanctions, the U.S. seeks to deter international banks from providing the financial infrastructure needed for these transactions. UPSC Relevance For aspirants, this development illustrates the interplay of sanctions with global energy security, highlighting the strategic importance of the Strait of Hormuz . It also underscores the role of financial watchdogs like OFAC in enforcing international norms, a point of interest for GS2: Polity (international relations) and GS3: Economy (global financial architecture). Understanding shadow banking mechanisms is essential for analysing how sanctioned states circumvent restrictions. Way Forward India’s diplomatic corps will need to monitor the impact on oil imports, especially if Iranian crude is rerouted through alternative channels. Policymakers should strengthen domestic AML (Anti‑Money‑Laundering) frameworks to avoid inadvertent breaches. Continued engagement with multilateral forums such as the UN and G20 can help shape a coordinated response to illicit financing while safeguarding energy supplies.
