Crude oil prices climbed on Monday after Saudi Arabia shut down its vital East-West pipeline following a drone attack from Iraq. This pipeline, which circumvents the Strait of Hormuz, is a crucial artery carrying up to 7 million barrels per day from Saudi oil fields near the Persian Gulf to export terminals on the Red Sea coast. The attack caused significant damage to a pump station, forcing Riyadh to halt operations, though officials have not disclosed the full extent of the damage or the expected downtime. Brent futures rose about 1% to settle at $105.68 per barrel, with U.S. crude increasing 1.3% to $101.39 amid already tense market conditions.

The closure poses a substantial threat to global oil supply since the pipeline has been instrumental in bypassing the strategic Strait of Hormuz, a hotspot for geopolitical conflict. According to Matt Smith of Kpler, if the shutdown lasts a month and storage at Saudi Arabia’s Yanbu port is drawn down, the market could lose up to 120 million barrels of crude exports. Analysts note that the immediate market reaction has been measured partly because Saudi stockpiles could temporarily offset the disruption, but longer outages are expected to push prices significantly higher.

Tensions in the region have escalated with the recent drone strikes and Houthi militant advances in Yemen, where the Houthis have captured strategic locations near critical Red Sea shipping lanes. These developments increase the risk of further interruptions to Saudi oil exports and create added pressure on global energy markets already strained by ongoing conflicts and sanctions. The security situation prompted the postponement of a planned diplomatic meeting in Oman aimed at addressing the Strait of Hormuz tensions.

Saudi Aramco’s CEO, Amin Nasser, highlighted the pipeline's importance in stabilizing oil supplies amid the Iran war, emphasizing its role even greater than strategic reserve releases by the U.S. The shutdown reveals the vulnerabilities of alternative crude routes and signals heightened supply risks that could boost oil prices if repairs take months, as some experts predict. Market watchers will be closely monitoring the situation for further developments affecting output and regional stability.
