Saudi Arabia's east-west oil pipeline remains offline following a drone attack, and if operations are not restored within days, the global market could face a supply shortfall of roughly 4%. This threat is intensifying as energy prices fuel inflation and push US Treasury yields to their highest levels since the 2008 financial crisis.

Industry buyers and traders report that stockpiles at the Yanbu terminal can only sustain exports for five to seven days. Should the pipeline fail to restart promptly, shipments from that facility are expected to drop sharply, according to sources familiar with the matter.

Pipeline Shutdown Drains Export Reserves

The east-west pipeline, which traverses the Arabian Peninsula, was shut down last Friday after an aerial drone assault. The conduit typically moves approximately 4 million barrels per day to the Red Sea port of Yanbu, representing about 4% of global supply.

Saudi Arabia's energy ministry stated that the Riyadh and Medina sections of the pipeline were struck multiple times, prompting a precautionary closure. The statement did not detail the method of attack, the perpetrators, or a timeline for resumption. This artery serves as a crucial alternative route for moving crude from eastern oil fields to Red Sea export facilities, particularly vital amid ongoing navigation constraints in the Strait of Hormuz.

Three industry insiders confirmed that terminal inventories at Yanbu can cover no more than five to seven days of export activity under current conditions. Additional reserves exist at Egypt's Ain Sukhna port on the Red Sea and the Sidi Kerir terminal on the Mediterranean, which could buffer supply for several more days. However, all sources stressed these backstocks will eventually be exhausted if the pipeline remains inactive.

Storage capacity estimates place Yanbu at roughly 35 million barrels, with Ain Sukhna and Sidi Kerir holding 18 million and 20 million barrels respectively. None of these facilities are currently operating at full capacity.

Uncertain Repair Timeline Heightens Market Volatility

Assessments of the damage and recovery period vary significantly among informed parties. One source suggests repair work could take up to five to six weeks, while another indicates the fix may be completed faster, with partial pumping potentially resuming during maintenance.

The absence of official clarity from Riyadh leaves traders unable to price the situation effectively. Analysts highlight the repair duration as the single most critical risk factor for oil markets. A partial restart within days could contain the shortage, whereas a delay stretching to weeks would present a far more severe test for global demand.

Deepening Global Supply Crisis

This pipeline disruption arrives during a historic downturn in Middle East energy exports. The International Energy Agency noted that Saudi supply fell to a thirty-year low in August, hampered by restricted access through both the Strait of Hormuz and Red Sea shipping lanes. The agency projects global oil supply will decline by approximately 5.7 million barrels per day this year, a reduction of about 6%.

Saudi Arabia reported August crude production at 6.2 million barrels per day, a dramatic drop from the 10.9 million barrels per day recorded in February before the conflict escalated. The region previously contributed roughly 22 million barrels daily; now, flows through the Strait of Hormuz have collapsed to a range of just 6 to 9 million barrels per day.

Compounding the pressure, Houthi forces seized an island at the entrance to the Red Sea, posing an additional threat to tanker traffic. These cascading supply disruptions continue to lift fuel costs globally, feeding through to inflationary pressures and bond markets, with US Treasury yields reaching heights not seen since 2008.
