Saudi Arabia is currently using a critical pipeline to prevent a severe global oil shock from becoming a full-blown crisis.
The heart of the problem is the effective closure of the Strait of Hormuz, the world's most important oil chokepoint. Following the outbreak of war in late February, Iran asserted control over the strait, causing tanker traffic to plummet by 90%. This has disrupted roughly 18 million barrels per day (mb/d) of oil flows, creating a massive hole in global supply and sending war-risk insurance costs soaring, making passage commercially unviable for many.
In response, Saudi Arabia has activated its primary backup plan: the East-West Pipeline, also known as the 'Petroline'. This pipeline stretches across the Arabian Peninsula, allowing Saudi Aramco to pump up to 7 mb/d of crude oil directly to the Red Sea port of Yanbu, completely bypassing the perilous Strait of Hormuz. This rerouting is the single biggest factor keeping the market from spiraling into chaos.
However, this solution has its limits. First, the pipeline's capacity, while substantial, only replaces about a third of the total oil flow disrupted at Hormuz. This leaves a staggering supply gap of around 11 mb/d. Recognizing this shortfall, the IEA (International Energy Agency) authorized a record-breaking release of 400 million barrels from emergency reserves to cushion the immediate blow. This strategic release provides a buffer, but it's a temporary fix, estimated to last just over a month at the current rate of disruption.
Second, there's a logistical bottleneck. Even if the pipeline carries 7 mb/d, the port of Yanbu must have the capacity to load that oil onto tankers. Current estimates suggest its practical loading capacity is closer to 3.8 mb/d, though this is being rapidly expanded. This constraint means some oil must be stored or production temporarily trimmed, even as the world desperately needs more supply.
Finally, the risk has merely shifted. The bypass route through the Red Sea is now facing new threats. Houthi rebels in Yemen have signaled their entry into the conflict, raising the possibility of attacks on tankers near the Bab el-Mandeb strait. This means the very lifeline preventing a crisis could itself become a target, moving the geopolitical flashpoint from the Persian Gulf to the Red Sea.
