The U.S. blockade on Iranian oil exports has significantly reduced the availability of crude for Chinese buyers, with only 10% of 40 million barrels offshore Singapore remaining unsold. This situation has led to a sharp increase in prices, with Iranian Light crude now offered at a premium of $3.50 over ICE Brent, compared to a discount of $3.50 just a week prior.34

According to data from Kpler, Iranian oil exports have plummeted since mid-July, with no supertankers crossing the Strait of Hormuz recently. The blockade has effectively stifled shipments from Kharg Island, Iran's primary export terminal, which handles 90% of its oil exports. As a result, the number of offers for Iranian oil cargoes to China has declined, forcing independent Chinese refiners to consider alternatives such as Brazil's Lapa crude and Iraq's Basrah crude.579

Muyu Xu, a senior crude oil analyst at Kpler, noted, “This suggests buyers could face virtually no new Iranian supplies available for late-September delivery onwards since no laden Iranian tankers have so far managed to break through the US blockade.” The total volume of Iranian crude outside the Persian Gulf has dropped to about 83 million barrels, down from over 100 million barrels before the blockade was reinstated. As the situation evolves, Chinese refiners are on alert for potential new sanctions, which could further complicate their supply chains.18

The U.S. Treasury Secretary has threatened Iran with “the most crushing economic operation ever taken against any country,” indicating that the pressure on Iranian oil exports is likely to intensify, leaving Chinese buyers scrambling for alternatives.

Key Insight
“Kpler data shows floating storage outside the blockade zone has fallen to about 80 million barrels from 105 million, with only two cargoes unsold near Singapore. Chinese teapots are now eyeing Brazil's Lapa and Iraq's Basrah crude, while Kpler's Muyu Xu warns they may cut throughput in October if inventories run thin.”
