Saudi East-West pipeline shutdown threatens ~4% of global oil supply
A vessel was struck by an unidentified projectile in the Strait of Hormuz [C005]. Separately, drone attacks forced Saudi Arabia to shut its East-West pipeline on Friday, cutting a route carrying around 4 million bpd to Yanbu [X215]. Traders and sources say Saudi Arabia could lose up to 4 million bpd of exports — roughly 4% of global supply — if pumping does not resume within days, with Yanbu storage covering only 5–7 days of exports plus smaller volumes in Egypt [X213, X214]. Repair estimates range up to 5–6 weeks, and Iran-allied Houthi forces continue pushing toward Bab el-Mandab [X226].
- Mechanism
- If the pipeline stays offline beyond the Yanbu storage window, crude and diesel prices would likely reprice higher, feeding inflation and bond yields.
- Wider market or sector impact
- A prolonged outage would deepen the global oil crunch and pressure inflation and bond yields [X214].
- Wider-impact evidence
- The pipeline had been Riyadh's bypass around the wartime Strait of Hormuz closure, so its outage removes the redundancy that had been keeping barrels flowing to the Red Sea.
- Countercase
- TankerTrackers argues Saudi Arabia historically seesaws exports between coasts and had Petroline at full capacity within 12 days of the conflict's start, with a +77% jump in combined exports over the past two weeks [X216].
- Next test
- Whether Aramco restarts the East-West pipeline within the 5–7 day Yanbu storage window [X213, X214].

SAUDI PIPELINE OUTAGE THREATENS LOSS OF 4% OF GLOBAL OIL SUPPLY UNLESS PUMPING RESUMES WITHIN DAYS, SAY TRADERS, SOURCES SAUDI ARABIA HAS STORAGE AT YANBU FOR JUST 5-7 DAYS OF EXPORTS, PLUS SMALLER AMOUNT STORED IN EGYPT, THREE SOURCES SAY

SAUDI PIPELINE OUTAGE THREATENS 4% OF GLOBAL OIL SUPPLY Saudi Arabia could lose up to 4 million barrels per day of exports — roughly 4% of global supply — if its critical East-West pipeline does not restart within days, Reuters reports. Saudi storage at Yanbu can sustain exports for only 5-7 days, according to sources. With repair estimates potentially stretching to 5-6 weeks, a prolonged outage risks deepening the global oil crunch and adding further pressure to inflation and bond yields.

Saudi Arabia risks losing up to 4% of global oil supply unless it restarts its major east-west pipeline to the Red Sea within days, threatening a key export route that has helped the kingdom bypass the wartime shutdown of the Strait of Hormuz, Reuters reported on Sunday. Drone attacks forced Riyadh to shut the pipeline on Friday, cutting a route that had been carrying around 4 million barrels per day to the Red Sea port of Yanbu. Yanbu has enough oil stocks to maintain exports for only five to seven days, three industry sources told Reuters, while smaller volumes are also stored at Egyptian

BREAKING: The closure of Saudi Arabia's East-West pipeline after recent strikes is set to remove 4% of global oil supply if it is not reopened this week, per Reuters. Currently, repair estimates are ranging up to 6 weeks, meaning we are set to lose another ~4 million barrels of daily oil supply. Iran-allied Houthi forces also continue to push toward the Bab el-Mandab Strait. Oil markets open in under 9 hours.
