Middle East conflict drives crude oil prices above $100/barrel in Q3 2026; refinery margins surge amid supply disruptions
Renewed military strikes in the Middle East pushed Brent crude oil to a quarterly peak of $109/barrel in September 2026, while U.S. refineries operated at 95% utilization with sharply elevated margins.
What happened
Brent crude oil prices climbed steadily through Q3 2026 following resumed military strikes on July 7, crossing $100/barrel on July 23 and again on September 9 after escalation against energy infrastructure in the Middle East and Russia. The front-month futures price peaked at $109/barrel on September 15, with spot prices reaching as high as $132/barrel around that time, before averaging approximately $104/barrel in the final two weeks of the quarter as markets weighed peace discussions against wider conflict risks. U.S. refinery utilization averaged 95%—the highest for a third quarter since 2019—processing crude oil at record levels, while crack spreads (refinery margins) for gasoline, distillate, and jet fuel all increased substantially compared to year-ago levels, with distillate and jet fuel spreads nearly tripling. U.S. distillate inventories fell to 13% below the five-year average as of late September due to high exports and elevated import costs, while gasoline and jet fuel inventories remained 7% below and 3% above their respective five-year averages.
Context
The supply disruptions reflect the intersection of reduced crude flows from major producers and capacity losses in refining infrastructure across Russia, China, and the Middle East. Earlier mitigating factors—notably reduced Chinese crude imports that had dampened global demand and U.S. Strategic Petroleum Reserve releases—began to reverse in Q3, with Chinese imports recovering modestly and SPR releases slowing significantly in September. The tightness in distillate and jet fuel supplies reflects their disproportionate loss from disrupted refineries in Russia and the Middle East, amplified by high U.S. exports to supply-constrained markets. The surge in crack spreads signals that refining capacity has become a constraining factor relative to crude supply, allowing refiners to capture higher margins on fuels even as crude prices elevated.
