Yuan-denominated crude futures on the Shanghai International Energy Exchange surged to 929.4 yuan, roughly $138.50 per barrel, on September 15, their highest level since the contract launched in March 2018. The rise followed drone attacks on Saudi Arabia's East-West pipeline, which had been moving about 4 million barrels per day, equivalent to roughly 4% of global oil supply. Saudi Arabia temporarily halted the entire route, with repairs estimated to require four to six weeks. The pipeline had become an important alternative to the Strait of Hormuz, allowing Saudi crude to reach Red Sea terminals amid heightened US-Iran tensions. Brent reached about $107 to $108 per barrel, while Oman and Murban traded above $126. Chinese refiners, which process roughly 14 million barrels per day, have paid higher premiums to secure supplies, although China's immediate import volumes had not been drastically affected. Markets are focused on whether the pipeline can return within the repair window and whether sustained prices will pressure Chinese refining demand. If the attacks are confirmed as originating from Iraq, they could also raise broader security concerns across Saudi Arabia's pipeline network.
