Iran Evades Renewed US Blockade With 12 Million Barrels for China
Iran evaded a renewed US naval blockade to export 12 million barrels of crude, highlighting a resilient sanctions-busting supply chain that continues to feed Chinese refineries and limit oil price shocks.
Six sanctioned Iranian supertankers slipped past a renewed American blockade in the Strait of Hormuz earlier this month, carrying an estimated 12 million barrels of crude. The vessels transited outbound to the Gulf of Oman between July 7 and July 14 with their tracking transponders switched off, according to vessel-tracking data. The covert movement occurred precisely as the US announced the reinstatement of the blockade on Iranian ports and oil cargoes.
The brief export window opened amid a rapid military escalation. On July 7, Iranian attacks on three commercial vessels in the Strait of Hormuz prompted immediate US military strikes on multiple targets inside Iran. In tandem, the US Treasury cancelled a waiver on Iranian oil sales that had been scheduled to remain in place until August 21.
Rather than halting exports, Tehran used the resulting month-long gap between blockades to stage a massive logistical operation. Data shows Iran moved roughly 57 million barrels of crude out of the Persian Gulf between mid-June and July 13. This surge provided a critical lifeline for Iranian exports that had been severely compressed by the initial US naval blockade.
The physical destination of these cargoes underscores the durability of Tehran's pre-war export tactics. Nine sanctioned Iranian tankers went dark off Malaysia this week, carrying crude valued by Vortexa at $989 million. Maritime intelligence firm Windward reported these vessels are predominantly headed for Shandong teapot refineries at Dongjiakou, a route "consistent with the established Iran-to-Malaysian-blend-to-China laundering route."
For commodity markets, the successful transit signals that physical interdiction remains an imperfect tool for restricting Iranian supply. Independent Chinese refiners continue to absorb sanctioned barrels, softening the potential bullish shock to global oil prices that a total supply cutoff would otherwise trigger.
The window for these movements, however, appears to be shutting. TankerTrackers.com noted that Iran "managed to ship out 60 million barrels of crude oil since the US Navy blockade paused in mid-June 2026." Looking ahead, the firm warned that if the blockade fully resumes, "Iran would be stuck with ~50 million barrels of crude oil and refined products."
