Saudi Pipeline Shutdown Threatens 4% Global Oil Supply, Raises Prices Amid Middle East Attacks

A drone strike forced Saudi Arabia to temporarily close its East-West oil pipeline, cutting roughly 4% of global oil flow and prompting concerns of a multi‑week outage. Traders warn that limited storage at Yanbu could sustain exports for only 5‑7 days, while repair timelines stretch up to six weeks. A simultaneous vessel attack in the Strait of Hormuz adds further pressure, pushing Brent crude above $100 per barrel and stoking inflation and yield worries.

Saudi Arabia's key East-West oil pipeline was shut down after a series of drone attacks, sending the country's shares lower and sparking immediate market alarm. The pipeline, which normally transports 4 to 5 million barrels per day, about 4% of global oil supply, now faces an uncertain restart window, with repair estimates ranging from five to six weeks. Traders note that Saudi storage at Yanbu can only cover exports for five to seven days, and smaller reserves in Egypt offer limited relief, heightening the risk of a prolonged supply crunch.

Compounding the pipeline disruption, a vessel transiting the Strait of Hormuz was struck by a projectile, a development reported by Reuters and highlighted by market observers as a further escalation in regional tensions. This dual threat to two of the world's most critical oil transit routes has already pushed Brent crude futures back above the $100 per barrel mark, reviving concerns that sustained high oil prices could feed inflation and keep long‑term bond yields elevated.

The convergence of these events underscores the fragility of global oil logistics in the Middle East. Analysts will be watching closely for any signs of pipeline repair progress and for additional attacks that could further disrupt the Strait of Hormuz corridor. Should the outage extend beyond the estimated repair window, the market may see sharper price spikes and increased volatility as buyers scramble for alternative supplies.
