U.S. blockade squeezes Iranian crude offers to Chinese refiners, prices surge

Iranian oil proposals to Chinese buyers have fallen sharply as the U.S. blockade curtails shipments, pushing prices higher.

Offers of Iranian crude to Chinese purchasers have dropped markedly this week, and prices have risen as the U.S. blockade limits Tehran's export capacity, according to trade insiders. The blockade, re-imposed on July 13, has halted most supertanker traffic carrying Iranian oil through the Strait of Hormuz, with ship-tracking data showing a sharp decline in floating storage volumes. While some Iranian grades are now priced above ICE Brent futures, earlier this week they were offered at a discount of about $3 a barrel.

Chinese “teapot” refiners in Shandong, which handle roughly a fifth of the country's refining, are seeking other sources, including Brazil's Lapa crude and Iraq's Basrah oil. U.S. Treasury Secretary Scott Bessent warned of forthcoming severe sanctions, prompting Chinese refiners to brace for possible buyer-specific measures, though past sanctions have not stopped processing Iranian oil. China remains the largest importer of Iranian shipments, accounting for over 80% of Tehran's oil exports.

Why it matters

The tightening U.S. embargo reduces Iranian oil flow to China, reshaping global crude markets and affecting energy prices.
