Asian refiners are waiting for clearer guidance from Saudi Arabia on the impact of the temporary shutdown of the kingdom’s East-West oil pipeline, a critical route that has allowed crude exports to bypass the Strait of Hormuz, after a major drone attack. The pipeline’s closure has created uncertainty over future loadings at Yanbu, Saudi Arabia’s major Red Sea export port, and raised fresh concerns about global oil supplies.
Saudi Arabia halted operations after drone attacks launched from Iraqi territory near the Iranian border damaged parts of the pipeline system and caused injuries. Riyadh described the shutdown as a precautionary measure while authorities assess the damage and secure the facilities.
East-West Pipeline Bypasses Hormuz
The East-West pipeline, also known as Petroline, transports crude from Saudi Arabia’s oil-producing regions near the Persian Gulf to Yanbu on the Red Sea coast. The roughly 750-mile system has a maximum capacity of about 7 million barrels per day, although recent flows were estimated at approximately 4 million barrels per day.
The pipeline became particularly important after the Strait of Hormuz was closed to shipping traffic amid the escalating Middle East conflict. By routing crude across Saudi Arabia by land, the system allowed the kingdom to continue exporting oil without relying on tankers passing through the heavily contested waterway.
Much of the crude previously loaded at Saudi Arabia’s Persian Gulf ports was redirected to Yanbu. However, the pipeline shutdown has now placed approximately 4 million barrels per day of Saudi crude shipments at risk, equivalent to around 4% of global oil supply.
| Key pipeline detail | Information |
|---|---|
| Name | Saudi East-West Pipeline, or Petroline |
| Route | Eastern Saudi Arabia to Yanbu on the Red Sea |
| Maximum capacity | Up to 7 million barrels per day |
| Recent estimated flows | About 4 million barrels per day |
| Strategic purpose | Bypasses the Strait of Hormuz |
| Current status | Temporarily shut after drone attacks |
Asian Refiners Face Delivery Uncertainty
Asian refiners have only recently adjusted to longer shipping routes and extended delivery times for Saudi crude. Some cargoes have been transported through the Mediterranean, while other tankers have been rerouted around Africa because of Houthi attacks and security threats near the Bab el-Mandeb Strait.
The latest shutdown creates uncertainty over whether cargoes scheduled for Yanbu will load on time, be delayed or be redirected to other Saudi export terminals. Refiners are also trying to determine whether Saudi Arabia will use stored crude at Yanbu to maintain shipments while repair crews work on the pipeline.
Industry sources estimate that Yanbu has enough inventories to maintain exports for only five to seven days if the pipeline remains offline. Saudi Arabia may also draw on supplies held at Egypt’s Ain Sukhna and Sidi Kerir terminals, which could provide additional flexibility for a limited period.
South Korean refiners are among the buyers monitoring the situation closely. The country’s authorities said domestic refiners had already secured more than 90% of their expected crude requirements for September and October, suggesting that the immediate impact may be limited. However, a prolonged outage could still force companies to seek alternative grades and suppliers.
Oil Prices Rise on Supply Risk
The pipeline closure triggered a fresh jump in crude prices. Brent crude rose more than 3% on Monday, approaching $108 a barrel, while U.S. West Texas Intermediate crude also moved higher. Traders are pricing in the possibility that Saudi exports could fall if the pipeline is not restored before Yanbu inventories are depleted.
The impact on oil markets will depend largely on the duration of the outage. A short shutdown would likely create delays and increase shipping costs, but a prolonged closure could remove millions of barrels per day from global supply at a time when other Gulf routes are already constrained.
The closure also highlights the vulnerability of infrastructure designed to bypass maritime chokepoints. The East-West pipeline was intended to protect Saudi exports from a Hormuz disruption, yet the land-based alternative has now become a target in the expanding regional conflict.
Repair Timeline Is Crucial
Saudi Arabia has not announced when the pipeline will resume normal operations. Traders and refiners will therefore focus on damage assessments, inventory levels at Yanbu and any changes to official loading schedules.

If the pipeline restarts quickly, the disruption may remain manageable. If repairs take weeks, Asian refiners could face tighter supplies, higher freight costs and increased competition for alternative crude grades. The uncertainty is already adding a geopolitical risk premium to oil prices.
For global markets, the key question is whether the shutdown remains a temporary precaution or develops into a sustained interruption affecting roughly 4 million barrels of daily exports. Until Saudi Arabia provides greater clarity, Asian refiners are likely to remain cautious about Yanbu cargoes and prepare for additional delays across an already strained energy-supply network.
