Tight refining capacity is keeping fuel prices stubbornly high even as crude oil costs have pulled back from recent peaks.
Gasoline was averaging roughly $4.40 per gallon nationally last week, while diesel climbed to around $6.37 per gallon, a dramatic rise from $3.70 just one year earlier.
West Texas Intermediate crude oil had meanwhile fallen to approximately $90 a barrel after surging to $119 back in March, creating an apparent contradiction in energy markets.
If crude oil prices were the primary driver of what consumers pay at the pump, the gap between falling crude and rising fuel costs would make little sense.
The real problem lies not in finding oil but in converting it into usable products like gasoline, diesel, and jet fuel, a process that depends entirely on refinery operations.
Crude oil cannot travel directly from a wellhead into a vehicle’s fuel tank, as it must first be processed through a refinery before it becomes any kind of usable fuel product.
The United States had 130 operable refineries at the start of 2026, with total operable distillation capacity sitting at approximately 18.2 million barrels per day.
That capacity figure represents a decline of more than 250,000 barrels per day compared to the previous year, driven largely by two refinery closures during 2025 that removed roughly 400,000 barrels per day from the network.
Smaller expansions at other facilities offset only part of that lost capacity, leaving overall domestic refining capability meaningfully reduced heading into 2026.
The global picture has grown even more constrained, with attacks on Russian refineries reducing worldwide supplies of finished fuel products at a critical moment for energy markets.
Disruptions in the Persian Gulf have further restricted international shipments of diesel and jet fuel, adding another layer of pressure to an already strained global supply chain.
Chinese refiners compounded the situation further by suspending exports of oil products to destinations outside Hong Kong and Macao, tightening global fuel supplies even further.
These converging pressures illustrate precisely why crude oil prices and fuel prices at the pump can move in opposite directions for extended periods of time.
When refining capacity is constrained, the ability to transform raw crude into consumer fuel becomes the critical variable that determines what drivers ultimately pay, not the price of oil itself.
Understanding this distinction is essential for anyone trying to make sense of energy costs in 2026, particularly as the refining industry continues to navigate closures, geopolitical disruptions, and capacity shortfalls.
