Iraqi Drones Hit Saudi Hormuz Bypass Pipeline as Diesel Signals Deeper Supply Stress
Iraqi drone strikes shut Saudi Arabia's main Hormuz bypass on September 10, while Houthi attacks continue to constrain the Red Sea route it feeds.
Gasoline reached a national average of $4.44 a gallon on Thursday (2026-09-17), 49% above its pre-war level, while diesel is running 68% higher than before hostilities began in late February. ICE Brent crude front-month is trading at $104.40 a barrel on Friday (2026-09-18).3
Saudi Arabia's East-West pipeline, the clearest working reroute around the Strait of Hormuz, is offline after Iraqi drone strikes shut it down on September 10 (2026-09-10). Before that strike, the line moved roughly 4 million barrels per day to Yanbu on the Red Sea. The Red Sea route it terminates in remains contested: Houthi attacks have degraded it as an export corridor throughout the conflict. The bypass capacity that crude pricing has partially relied upon is under pressure from two sides simultaneously.3
The IEA estimates existing Saudi and UAE pipeline routes can reroute only 3.5 million to 5.5 million barrels per day, against the roughly 15 million barrels that moved through Hormuz daily before the war, around 34% of all global crude trade, most of it Asia-bound. That leaves a gap too wide for pipeline bypass alone to cover.3
Energy Secretary Chris Wright told CNBC on Wednesday (2026-09-02) that more than 17 million barrels transited Hormuz under US military protection on Monday (2026-08-31), a wartime record. Convoy-escorted passage has kept crude moving. But the Pentagon confirmed in writing this week (week of 2026-09-14) that the war has cost $38 billion in its first four months and produced a munitions shortfall. Military-protected transit through an active conflict zone cannot be assumed permanent.1,3
Kuwait illustrates the exposure of producers without a pipeline alternative. Output there collapsed from 1.16 million barrels per day in March to 573,000 barrels per day in May before a partial recovery. Qatar and Kuwait combined, neither of which has its own bypass pipeline, have pushed exports back to roughly 70% of the pre-war 2 million barrels per day using shuttle tankers through the strait. Regional forecasters project GDP contractions of 5.9% for Qatar and 2.9% for Kuwait in 2026, the steepest in the GCC. That degree of economic stress limits investment in production recovery.3
Diesel has moved further from pre-war levels than gasoline. Retail diesel reached a record $5.85 a gallon on Thursday (2026-09-03), exceeding the 2022 high and up 53% from the pre-war baseline of $3.76, according to the American Automobile Association. By Thursday (2026-09-17), the national average was still running 68% above pre-war, against gasoline's 49% gain over the same period. ING commodities analysts attribute much of the gap to Russia's position as the world's second-largest diesel exporter: the Gulf and Russia crises together have removed roughly 20% of the diesel that normally moves by sea, per ING's estimates.2,1,3
Consumer prices rose 3.4% year-on-year in August, up from 2.4% in February.3
ICE Brent crude front-month at $104.40 on Friday (2026-09-18) has absorbed the supply shock in headline terms. But the September 10 (2026-09-10) pipeline strike, simultaneous Houthi pressure on the Red Sea, and Kuwait's output falling to under half its March level through May are compounding rather than resolving. How long the East-West pipeline stays offline, and whether Red Sea conditions deteriorate further before it restarts, is the test for the IEA's 3.5 to 5.5 million barrel bypass ceiling. Diesel at 68% above pre-war, with Russian and Gulf disruptions layered together, is where that ceiling pressure shows most clearly.3,1
