Saudi Pipeline Outage Hits an Oil Market Running Out of Buffers

After seven months of war-related disruptions, oil markets are running short of the stocks and logistical alternatives that cushioned prices early in the crisis. A drone strike that put Saudi Arabia’s East-West pipeline out of service has raised the prospect of weeks-long interruptions to roughly 4 million barrels per day (bpd) of shipments routed to the Red Sea, tightening already thin global supplies.

Why It Matters

The outage risks curtailing large flows that had helped Saudi Arabia bypass the Strait of Hormuz at a time when strategic reserves and floating crude holdings have been markedly depleted, increasing the chance of further price spikes and broader fuel-market stress.

Key Facts

Conflict duration: Seven months of disrupted oil flows through the Strait of Hormuz
Pipeline affected: Saudi East-West pipeline out of service after drone attacks at the end of last week
Volume at risk: About 4 million barrels per day of Saudi crude shipments from Yanbu potentially jeopardized

The Middle East oil disruption that began when the Strait of Hormuz was closed to tankers has entered its seventh month, and market buffers that absorbed early shocks have been largely exhausted. Floating inventories that had provided temporary oversupply were drawn down rapidly, and strategic stock releases from agencies including the IEA have cut into government reserves. In the United States, the Strategic Petroleum Reserve is at its lowest level since the early 1980s.

The situation worsened after drone strikes disabled Saudi Arabia’s East-West pipeline, a key route that allowed the kingdom to load much of its crude from the Red Sea port of Yanbu instead of using Gulf terminals. Analysts say the outage risks undermining roughly 4 million bpd of shipments from Yanbu; Saudi authorities could sustain exports from local stocks for a short period, but a prolonged stoppage would threaten those Red Sea flows already targeted by Iran-aligned Houthi attacks on shipments and tankers.

Market indicators are reflecting the tighter supply picture. The IEA reported global observed oil inventories fell by another 95 million barrels in August, bringing cumulative draws since February to about 507 million barrels (an average of 2.8 million bpd). Volumes of oil on water declined by 65 million barrels amid renewed attacks on tanker traffic. Price-sensitive signals have followed: U.S. average diesel topped $6 per gallon for the first time while industry executives and strategists warn risks are skewed to higher prices in the coming months.

Traders and refiners have tried to adapt by redirecting and replacing some flows; exports through the Strait of Hormuz have recovered to more than half of pre-war levels thanks to dark transits and U.S.-escorted passages. Still, with storages depleted, tanker and war-risk insurance costs up, and some Middle Eastern capacity effectively offline, market participants say the longer the conflict persists the more likely another significant price surge becomes. For now, analysts note demand destruction would be the primary mechanism to rebalance markets if supply disruptions continue.
