The US Treasury determined that Executive Order 13902 applies to Iran's automotive and rail sectors, effective October 1 with no wind-down period. The measures target Iranian manufacturers alongside international suppliers based in the UAE, Hong Kong, and mainland China. Foreign financial institutions facilitating transactions in these sectors now face secondary sanctions exposure.
The U.S. Treasury Department announced expanded sanctions under Operation Economic Outcast, designating Iran's rail and automotive sectors under Executive Order 13902. The measures penalize dozens of entities, including suppliers and financial intermediaries based in the UAE, China, Hong Kong, Turkey, and Germany. The action also targets heavy machinery, steel export channels, and the Russia-linked A7 shadow banking network.
US Treasury measures against Iran place an increasing investigative burden on foreign banks to monitor opaque cross-border transactions, including transfers disguised between Hong Kong and Dubai companies. Prior to the closure of the Strait of Hormuz, China bought an estimated 90% of Iran's oil exports, with trade largely settling in renminbi through shadow-banking channels. Secondary sanctions under Operation Economic Outcast threaten to cut non-compliant foreign institutions off from dollar clearing.
