Why Saudi Arabia’s East-West pipeline matters for global oil

The temporary closure of Saudi Arabia’s 1,200km East-West pipeline has sent shockwaves through the global oil market, raising concerns about the fragility of the industry’s supply chain. The suspension of the pipeline, which affects up to 5% of global oil supply, comes at a critical time for an already tight market.

The attack on the pipeline by drones, allegedly launched from southeastern Iraq, is just one in a series of incidents disrupting oil flows through the Middle East. The US-Israel war on Iran has severely reduced oil exports through the Strait of Hormuz, while Houthi forces in Yemen have intensified attacks around the Red Sea and Bab al-Mandeb.

The East-West pipeline’s significance lies in its ability to bypass the Strait of Hormuz, allowing Saudi Arabia to maintain a significant share of global oil supply. With the pipeline carrying approximately 4-5 million barrels per day (bpd), it represents about 4% of global oil exports. However, the closure has exposed the vulnerability of this crucial infrastructure.

The International Energy Agency warned earlier this year that global inventories have been falling, with Saudi oil supply reaching a more than three-decade low in August. If the pipeline remains shut, prices are likely to rise, potentially hitting critical levels.

This incident highlights the interconnectivity and fragility of global energy systems. As Gavekal Research noted, if Yanbu were to go offline due to Houthi drone attacks, it would be a disaster for the world at a time when global refining capacity is already critically tight.

The East-West pipeline shutdown serves as a reminder that the global oil market faces unprecedented challenges. Regional conflicts, security threats, and logistical disruptions are taking their toll on supply chains, making them increasingly vulnerable to shocks.

The world’s reliance on Middle Eastern oil, particularly from Saudi Arabia and the Gulf states, has long been a concern for global stability. The closure of the East-West pipeline demonstrates that these concerns are not unfounded. As the market adjusts to this new reality, it is essential to consider alternative scenarios, such as increased investment in renewable energy sources or development of new supply routes.

The longer-term consequences of this incident will depend on the extent of the damage and the duration of the shutdown. However, one thing is clear: the East-West pipeline closure has exposed a critical vulnerability in the global oil supply chain, underscoring the need for greater resilience and adaptability in an increasingly uncertain world.

Policymakers must prioritize dialogue, cooperation, and diplomacy to prevent further disruptions. The stakes are high, not just for the global economy but also for global stability itself.
