The U.S. Treasury sanctioned Iran’s auto and rail sectors on Thursday, designating state-owned rail firms and suppliers across the UAE, Hong Kong, Turkey and Indonesia, and separately hit the A7 network — a Russia-linked financial channel Treasury says Iran uses to evade sanctions. The designations extend the pressure campaign from energy and shipping into Iran’s domestic industrial base and its sanctions-evasion plumbing.
Treasury Secretary Scott Bessent added a striking claim on social media: that Iran loaded “zero crude oil” onto tankers in September. If shipping data bears that out, seaborne Iranian exports have been squeezed to zero — the blockade’s financial weapon is working at full effect, and Iran’s only remaining leverage is the strait itself rather than its own barrels.
The verification matters. Iran’s historical sanctions evasion relied on ship-to-ship transfers, dark fleet tankers and renamed bills of lading; a true zero would mean the current enforcement regime has closed channels that survived every prior sanctions round. Tanker-tracking data in the coming days is the test.
