• Saudi Arabia has returned crude flows on the East–West pipeline to about 5.5 million b/d, freeing an estimated 4.0–4.5 million b/d for export from Yanbu on the Red Sea.
  • The recovery eases supply fears after a September drone attack shut the key bypass around the Strait of Hormuz, though Red Sea shipping risks persist.
  • Brent crude fell more than $2 toward $97 on the restart news, but traders remain cautious as the system runs on a temporary bypass.

Pipeline Back Online

Saudi Arabia has restored crude flows on its East–West pipeline to roughly 5.5 million barrels per day (b/d), according to industry estimates, leaving about 4.0–4.5 million b/d available for export from the Red Sea port of Yanbu. The recovery follows a September 10–11 drone attack that damaged three of the pipeline’s 11 pumping stations and forced a temporary shutdown of the 1,200-km link.

State-owned Saudi Aramco built a temporary bypass around the most affected pumping station, and tanker loading at Yanbu has resumed. By late September, throughput had climbed to 2.0–2.65 million b/d, with expectations of 3–4 million b/d shortly after. The latest rebound to 5.5 million b/d marks a significant step toward normalizing operations on the kingdom’s main alternative to the Strait of Hormuz.

Export Capacity Versus Pipeline Capacity

The distinction between pipeline capacity and export capacity is crucial. The East–West pipeline has a stated capacity of about 7 million b/d, but domestic refineries, power plants, and desalination facilities along the Red Sea coast consume a portion of that crude, reducing the volume available for export. Port and berth availability, as well as security conditions in the Red Sea, further constrain loadings.

“The recovery to around 5.5 million b/d is significant, but it does not necessarily mean a fully normalized system,” said one person familiar with the matter. “The temporary bypass may preserve flows while permanent repairs continue for weeks.”

Aramco had been rerouting around 4 million b/d through the pipeline—about 4% of global oil supply—even before the latest attacks, as conflict disrupted maritime movements through Hormuz. That makes the system a globally consequential piece of energy infrastructure.

Market Reaction and Implications

News of the pipeline restart and renewed Yanbu loadings contributed to lower oil prices. On September 22, Brent crude fell by more than $2 per barrel toward $97 as traders priced in a partial restoration of Middle Eastern supplies. The reduction in Red Sea refinery operations, including the shutdown of Aramco’s 400,000-b/d Jizan refinery after an early-September attack, has also raised the crude volume potentially available for export.

Asian refiners, especially those dependent on Saudi medium and heavy crudes, stand to benefit from greater delivery reliability. However, alternate delivery methods—such as ship-to-ship transfers in the Gulf of Oman—and route risk can increase freight and crude-acquisition costs.

Red Sea Risks Linger

Despite the pipeline restart, the Bab el-Mandeb route remains vulnerable to threats from Yemen-based Houthi forces. Restoring pipeline flow does not eliminate tanker, insurance, routing, and freight-rate risk. Shipping firms and crews continue to face elevated security risks in the Red Sea and nearby waters.

Saudi Arabia attributed the September drone attacks to Iraqi militias, according to Reuters (TRI). The episode demonstrates how energy infrastructure has become a direct target in the regional conflict. For Saudi policymakers, the restart supports export revenue, fiscal stability, and the kingdom’s reputation as a dependable supplier.

Aramco did not immediately respond to a request for comment.

What to Watch

Market analysts will watch whether exports shift back from Gulf-of-Oman ship-to-ship arrangements toward Yanbu. Argus cautioned that renewed Yanbu loadings may not fully displace alternative arrangements because Bab el-Mandeb risks remain. Meanwhile, Saudi exports through the Gulf port of Ras Tanura reportedly rose to 3.6 million b/d in September, from below 1 million b/d in August, reflecting efforts to compensate for the pipeline disruption.

The recovery to 5.5 million b/d is likely to ease the immediate supply shock and put downward pressure on the geopolitical risk premium in crude prices, assuming cargoes can move safely through the Red Sea. But the restoration will remain fragile if attacks recur, if port congestion develops, or if Red Sea vessel-security risks curtail tanker calls.
