Saudi pipeline outage risks 4% cut to global oil supply within days
Published 14 September 2026
Saudi Arabia could exhaust its Red Sea export stocks within five to seven days unless its east-west pipeline restarts, putting roughly 4% of global oil supply at risk.
Saudi Arabia's east-west pipeline, which normally carries around 4 million barrels a day across the Arabian Peninsula to the Red Sea port of Yanbu, has been offline since a drone attack forced its closure last Friday. Yanbu holds enough stock to cover only five to seven days of shipments, according to three industry sources cited by Reuters, and Saudi Arabia has not disclosed the extent of the damage or a firm restart date.
The closure matters because this pipeline has been the kingdom's workaround for the wartime disruption to the Strait of Hormuz, rerouting crude away from a chokepoint where flows have already fallen to between 6 million and 9 million barrels a day. Houthi fighters in Yemen also seized an island at the entrance of the Red Sea on the same day, adding a second layer of risk to the route. Repair estimates vary widely: Reuters reported one source suggesting five to six weeks, another suggesting partial pumping could resume sooner.
What this means for UK buyers
A 4% cut to global oil supply does not move UK wholesale gas or power markets directly, but it tightens the same physical and financial conditions that shape NBP gas and Season-1 power pricing: freight, insurance, and crude-linked LNG contracts all reprice on Hormuz and Red Sea risk. The International Energy Agency (IEA) already estimates a 5.7 million barrel-a-day fall in global supply this year, roughly 6%, and Saudi output has dropped from 10.9 million barrels a day in February to 6.2 million in August. For buyers renewing fixed contracts through Q4, this is a moment to watch crude benchmarks closely rather than react to headlines alone.
The chart below tracks Brent crude over recent months, giving UK buyers a benchmark against which this supply scare can be measured.

Why this window: Last 7 days — 7.3% range, 1.8% net move higher. Tight window picked so the week's price action is visible.
- Yanbu storage capacity: approximately 35 million barrels
- Ain Sukhna and Sidi Kerir (Egypt) combined capacity: approximately 38 million barrels
- Strait of Hormuz flows: down to 6-9 million barrels a day from a pre-war 22 million
- Saudi crude output: 6.2 million barrels a day in August, versus 10.9 million in February
- Pipeline repair estimates: five to six weeks per one Reuters source, faster if partial pumping resumes
The Financial Times reported that the shutdown has already raised fears over global supply resilience, while Bloomberg noted the pipeline's role as the kingdom's main bypass for Hormuz-related disruption. Egypt's Ain Sukhna and Sidi Kerir ports can support customers for several days, but none of these buffers are fully replenished, and all four sources cited by Reuters agree stocks run out if the pipeline stays down.
The repair timeline is the number to track. A restart within days would limit the damage to a supply scare; five to six weeks offline, as one source suggested, would test the storage buffers directly and pass through to freight and crude-linked pricing that UK buyers see in their gas and power renewals.
