Saudi Oil Pipeline Inventories Down to Just 5-7 Days as 4% of Global Supply Faces Disruption
nashnova research
Saudi Arabia's East-West pipeline shut down after a drone strike, leaving Yanbu port with only 5 to 7 days of export inventory; if the line cannot restart within days, global oil supply faces an ≈4% gap — a direct supply-side blow to prices already at all-time highs and inflation already running hot.
Why does this one pipeline matter so much?
The East-West pipeline spans roughly 1,200 km across the Arabian Peninsula, carrying about 4 million barrels per day — roughly 4% of global supply.
After the Strait of Hormuz was disrupted by conflict, this pipeline became the sole major alternative route for Middle Eastern crude to reach the Red Sea via Yanbu. It has served that role for over six months.
This means → it is not an ordinary pipeline but the main artery of the current Middle East oil-export system. Nothing of comparable capacity can substitute.
How long can inventories last?
Yanbu's tank capacity is about 35 million barrels, but current stock levels are low — enough for only 5 to 7 days of exports.
Saudi Arabia holds additional reserves at two Egyptian ports: Ain Sukhna (Red Sea, ~18 million barrels) and Sidi Kerir (Mediterranean, ~20 million barrels). These buy a few more days but cannot sustain exports long-term.
In plain terms = add all three depots together and the "out of oil" deadline only shifts from one week to roughly two. If the pipeline stays down, depletion is a matter of when, not if.
When can the pipeline be repaired?
As of publication, the Saudi government had not disclosed the extent of damage or the expected duration of the shutdown. The energy ministry did not respond to requests for comment.
Sources disagree: one said repairs could take 5 to 6 weeks; another believed it could be faster, with partial pumping resuming during repairs.
This means → the best case is a gradual restart within days; the worst case is a shutdown exceeding a month, by which point all inventory buffers would be exhausted.
Is the Red Sea route also deteriorating?
Houthi forces seized Perim Island — a strategic island in the middle of the Bab el-Mandeb Strait — last Friday, further threatening the Red Sea shipping lane.
Oil flows through the Strait of Hormuz have already plunged from a pre-war level of roughly 22 million bpd across the Middle East to just 6–9 million bpd now.
This reflects a simultaneous narrowing of both major Middle Eastern export corridors — the strait and the pipeline — leaving almost no buffer for the global market.
What about Saudi Arabia's own production?
IEA data show Saudi oil output in August fell to its lowest level in 30 years.
The numbers: production dropped from 10.9 million bpd before the war began in February to 6.2 million bpd in August — a decline of more than 40%.
In plain terms = Saudi Arabia is not just struggling to ship oil out — its output itself has collapsed. The pipeline shutdown is another cut on top of a base that is already halved.
What does this mean for global oil prices and the economy?
The IEA forecasts global oil supply will fall by about 5.7 million bpd this year, a drop of roughly 6%. A prolonged pipeline shutdown would widen that gap further.
Global fuel prices have already hit all-time highs, driving inflation higher and pushing U.S. Treasury yields to their highest since the 2008 financial crisis.
This means → the pivotal question is singular: can the pipeline restore partial operations before inventories run out? If yes, the shock stays manageable. If no, the world faces a textbook supply-side oil crisis.
