Hedge Funds Extend Gasoline Longs as Iran War Outlasts Market Expectations
Speculative money has flipped to a 177 million barrel net long in fuel markets as the Iran conflict proves more durable than traders priced.
RBOB gasoline front-month added 0.30% to $3.38 a gallon as of early Monday (2026-09-14), sustaining a rally built on a geopolitical supply squeeze that has proved far more durable than the market initially expected when the U.S.-Iran conflict began.6,7
For the first four months of the war between the United States, Israel, and Iran, the prevailing market view was bearish. Traders expected hostilities to end before summer, assumed Hormuz oil flows would recover, and kept fuel exposure light. Instead, the world is slipping into a deepening fuel shortage, oilprice.com reported on Tuesday (2026-09-08).6
By September 1 (2026-09-01), money managers had reversed course. Hedge funds built a combined net long of 177 million barrels across gasoline and diesel futures, having been short those same contracts for much of the preceding months, John Kemp reported in a recent column. In crude, their aggregate position remained "slightly bearish" even as they accumulated refined product exposure, a split that prices in a product squeeze while hedging against any sudden diplomatic resolution.6
ICE Brent crude front-month stood at $107.61 a barrel as of early Monday (2026-09-14), extending gains that began when oil crossed $100 for the first time in two months on Wednesday (2026-09-09). Goldman's head of oil strategy, Daan Struyven, said the intensity and geographical breadth of tanker attacks, which he called a "highly uncertain variable," would remain the principal driver of whether Gulf oil exports recover and at what pace.7
Brent's ascent this summer has been steep. After Iran-backed Houthi militants attacked two Saudi Arabian tankers in the Red Sea, ICE Brent front-month surged roughly 7% on July 23 (2026-07-23), extending its monthly advance to over 35% at that point.4
In refined products, tightness has been more acute than in crude. The RBOB-Brent crack spread reached $43.04 a barrel around June 24 (2026-06-24), the highest level cited in recent oilprice.com reporting. Diesel and gasoil have struggled under softer industrial demand, while gasoline has held up. U.S. gasoline inventories stood at 214.24 million barrels as of June 12 (2026-06-12), running 14.29 million barrels below the five-year seasonal average.3
GasBuddy warned on Monday (2026-08-03) that U.S. retail gasoline prices could hit a calendar record that week, citing the preceding month's crude market volatility. BMI, a unit of Fitch Solutions, projected at the same time that gasoline prices would remain elevated over the following three to six months, pointing to deteriorating U.S.-Iran relations as the key variable.5
The risk in the gasoline trade is that speculative positioning has grown crowded. Contrarian signals on RBOB gasoline front-month point bearish on a positioning basis, suggesting the 177 million barrel net long is now a potential source of selling pressure rather than fresh buying power if the geopolitical backdrop softens. The same bearish contrarian signal applies to ULSD heating oil front-month.6
Commerzbank analyst Norman Liebke noted on June 8 (2026-06-08) that inventories had lasted longer than many expected, even as some product stocks had already tightened considerably. He cited a reported decline in global oil production of approximately 10.5 million barrels per day for March as evidence that supply was strained before the conflict's latest phase.2
EIA data for the week of May 11 (2026-05-11) showed U.S. crude and petroleum product exports hitting a record 14.2 million barrels per day, 33% above the equivalent week in 2025. Total U.S. stocks, including the Strategic Petroleum Reserve, fell roughly 24.1 million barrels that week, one of the five largest weekly draws on record. Domestic supply was already stretched before the summer escalation compounded the pressure.1
For RBOB, the next catalyst runs through the Red Sea and Hormuz. If Houthi attacks intensify or widen geographically, a speculative crowd already carrying 177 million barrels of fuel exposure may push prices higher still. But a credible easing of hostilities would find that position with little room to move except lower, and the "slightly bearish" crude stance that hedge funds have maintained alongside their fuel longs suggests any unwind could be swift and broad.7,6
