Saudi Arabia is funneling crude oil shipments through the Strait of Hormuz after drone strikes knocked out its primary alternative export route, the East-West Crude Oil Pipeline known as Petroline. The pipeline, which stretches 1,200 km from eastern oil fields to the Red Sea port of Yanbu, was shut down on September 10 following attacks on pumping stations in the Riyadh and Medina regions.
What happened and why it matters
Saudi officials attributed the strikes to drones launched from Iraq’s Maysan province. Rather than retaliating immediately, the kingdom said it was respecting a request from Iraq’s prime minister for time to address the situation domestically. Satellite imagery confirmed major damage, including fires at pumping stations along the route.
Before the attack, the Petroline was moving 4 to 5 million barrels per day. That represents roughly 4% to 5% of global oil supply flowing through a single piece of infrastructure. Its design capacity is even higher, at up to 7 million bpd.
Repair estimates range from three to six weeks. Storage capacity at the Yanbu port, the pipeline’s western terminus, can only sustain five to seven days of exports at current consumption rates.
Brent crude responded the way you’d expect. Prices surged into the $105 to $110 per barrel range by September 14, crossing the psychologically significant $100 threshold for the first time in this cycle.
A supply picture that was already ugly
Saudi crude exports had already fallen to a 13-year low of 3.2 million bpd in August, the result of multiple overlapping disruptions that have squeezed the kingdom’s ability to get oil to market.
The Strait of Hormuz itself has been anything but calm. Escalating tensions involving the US, Israel, and Iran have created recurring friction in the waterway since late February. About a fifth of the world’s petroleum passes through that 21-mile-wide gap between Oman and Iran on any given day.
Market and geopolitical fallout
Saudi Arabia’s decision to hold off on retaliation adds a diplomatic dimension worth watching. The restraint buys Iraq’s government time but also creates an implicit deadline.
The repair timeline is the single most important variable for energy markets over the next month. Every additional week the Petroline stays offline compounds the pressure on Hormuz transit and tests the limits of Yanbu’s five to seven days of storage capacity.
