Global refined petroleum markets are tightening as disruptions across the Middle East, Russia and Asia constrain gasoline, diesel and jet fuel supplies. While crude oil prices have fluctuated amid the Iran conflict, refined products have moved sharply higher, widening the gap between crude prices and finished fuels. Gasoline prices are reportedly up 98% this year compared with a 44% increase in West Texas Intermediate (WTI) crude.

Middle East disruptions have had an outsized impact on fuel availability. The closure of the Strait of Hormuz and strikes affecting regional refineries have disrupted more than 20% of global seaborne petroleum product trade. Unlike crude oil, refined products have fewer options for rerouting volumes through pipelines, increasing the market impact when shipping and refining infrastructure is unavailable.
Additional pressure is coming from Russia, where Ukrainian drone attacks have reportedly taken more than 40% of the country’s refining capacity offline, equivalent to roughly 3% of global capacity. Russia has increased crude exports but restricted gasoline and diesel exports while importing some finished fuels. China has also reduced petroleum product exports to protect domestic supplies. That leaves the United States as one of the few major refining centers operating without comparable disruptions, but strong exports are drawing down already-tight U.S. inventories.
The supply squeeze is producing exceptionally strong refinery margins. Bank of America estimates diesel and gasoil crack spreads — the difference between crude oil costs and refined product prices — have increased more than 85% since June, while jet fuel cracks have climbed nearly 140%. The market is entering a seasonally strong period for diesel consumption, including agricultural harvest demand, with inventories across the U.S., Europe and Asia near multi-year lows. Capital Economics expects crude prices could ease as Strait of Hormuz traffic recovers, but refined product prices may remain elevated into 2027 if Russian refinery disruptions continue.
Industry Impact
For North American operators, drilling contractors, service companies and suppliers, higher diesel prices can increase drilling, completion, trucking, construction and field-service costs even if crude prices decline. The widening disconnect between crude and refined fuels means energy-sector operating costs may remain under pressure longer than headline oil prices suggest.
Two-Sentence Summary
Global refinery and shipping disruptions are tightening gasoline, diesel and jet fuel supplies, driving refined product prices significantly faster than crude oil. North American oilfield operators and service companies could continue facing elevated fuel and transportation costs even if crude prices retreat.
