• Saudi Arabia has resumed crude flows through the East–West Pipeline after drone attacks, but the restart is partial: oil is reaching Red Sea refineries while tanker exports from Yanbu have not yet resumed.
  • The pipeline, which bypasses the Strait of Hormuz and normally carries about 4 million barrels per day, remains a critical supply route. Full restoration could take six weeks or more, according to industry and security sources.
  • The cautious restart limits immediate relief for global oil markets, with Brent crude initially falling more than $2 per barrel on the news but physical supply still constrained.

Cautious Restart

Saudi Arabia has restarted its East–West Pipeline after a drone attack earlier this month forced a shutdown, but the recovery is far from complete. Crude is flowing toward Red Sea refineries, yet commercial tanker loadings from the Yanbu terminal have not resumed, according to people familiar with the matter and shipping data. Two tankers scheduled to load on September 23 had not loaded as of September 24, and about six tankers are expected at Yanbu during September 24–27.

The pipeline, which spans 1,200 kilometers (745 miles) from eastern oil fields to Yanbu on the Red Sea, had been carrying roughly 4 million barrels per day—about 4% of global oil supply—as a bypass to the Strait of Hormuz during regional conflict. The September 22 restart was initially at low rates, with operators building enough inventory, or "critical mass," at Yanbu before resuming commercial deliveries.

Three pumping stations were damaged in the attacks, which Saudi Arabia attributed to Iraqi militia. Satellite imagery showed repair and bypass work, and sources estimate that full restoration could require six weeks or more. Iraq has acknowledged that the attack originated in its Maysan governorate, removed a military commander, and opened an investigation.

Market Impact

The pipeline restart initially pushed Brent crude down more than $2 per barrel as traders interpreted it as a step toward restoring Middle Eastern supply. However, the lack of tanker loadings limited the immediate physical-supply benefit. Oil prices had already risen above $100 per barrel amid the regional conflict, and the pipeline outage exacerbated concerns about supply disruptions.

The route is strategically vital because it avoids the Strait of Hormuz, but its vulnerability shows that rerouting away from one chokepoint does not fully resolve regional security risk. The restart reduces a key operational threat for Saudi Aramco (2222.SR), the state-controlled oil giant, but does not eliminate it. Exports require both safe pipeline throughput and dependable access to Yanbu’s marine terminals.

Aramco reported strong Q2 2026 results, with adjusted net income of $33.4 billion, up from $25.2 billion a year earlier, supported by an average realized crude price of $108.10 per barrel. The company’s net gearing stood at 6.2% at June 30, and the board declared a $21.9 billion Q2 base dividend. The pipeline is a core part of Aramco’s logistical network, enabling exports through Yanbu and supplying Red Sea refineries.

Broader Implications

The incident underscores the value of redundant infrastructure—pipelines, storage, multiple ports, and flexible refining systems—over reliance on a single shipping chokepoint. The Gulf Cooperation Council condemned the attack as an escalation against Saudi infrastructure and sovereignty. Saudi Arabia has so far sought accountability and prevention measures from Iraq rather than announcing immediate retaliation.

European refiners were told Aramco was still accumulating volumes at Yanbu, delaying deliveries and raising procurement uncertainty. Shipping and insurance markets face higher risk premia and possible rerouting, with longer voyages adding roughly 30 days in some cases, according to Energy Aspects cited by the BBC.

The broader conflict has a severe humanitarian dimension. The UN reported at least 76,000 people displaced in Yemen since July, with the number rising sharply amid recent fighting.

What to Watch

Short term, pipeline flows should gradually rise, but commercial exports from Yanbu depend on successful pressure testing, inventory accumulation, and safe loading operations. The immediate signal to monitor is confirmed tanker loading—not merely pipeline restart. Full throughput is not expected quickly; sources estimate at least six weeks, potentially longer, for full recovery.

Medium term, if repairs hold and the Red Sea remains navigable, renewed Yanbu exports would improve supply availability and ease some upward pressure on oil and diesel prices. Conversely, further attacks on pumping stations, Yanbu facilities, or Red Sea shipping could reverse those gains quickly.

Aramco did not immediately respond to a request for comment on the tanker loading delays. The central uncertainty is not Aramco’s ability to repair the pipeline—it is whether the surrounding regional conflict continues to threaten the entire export chain from fields to pipeline to Red Sea tanker routes.
