Saudi Arabia shut the Petroline, its main oil export bypass, on September 11, 2026, after drone attacks damaged pumping stations along the route the previous day. The East-West pipeline moves roughly 4 million to 5 million barrels per day from Abqaiq in the eastern oil fields to Yanbu on the Red Sea, representing about 4% to 5% of global oil supply. Brent crude surged above $100 per barrel and touched $110 before stabilizing. The 1,200-kilometer pipeline avoids the Strait of Hormuz, through which roughly one-fifth of global oil flows, an increasingly important advantage since the US-Israel-Iran war began in February 2026. Saudi Aramco expects to restore about half of recent throughput within days, while full repairs could take five to eight weeks. Yanbu's approximately 15 million barrels of storage could support exports for roughly five to seven days at current extraction rates, making the repair timeline the central issue for oil markets.
