NEW YORK / RankWire.AI / – As inventories tighten and refinery outages persist, diesel prices remain elevated in the United States and Europe. On Monday, U.S. ultra-low sulfur diesel futures surged 7.4% to close at $4.19 a gallon, marking the largest single-day increase since July 13. Early Wednesday, the contract traded near $4.28 a gallon, reflecting ongoing concerns over limited supply in key consuming regions.
The U.S. continues to see diesel stockpiles well below recent seasonal averages. According to the U.S. Energy Information Administration, distillate inventories for the week ending July 31 totaled 107.2 million barrels, which is 3.5 million barrels less than the previous week. These stocks are also 5.1% below the same period last year and 16.1% under the comparable figure in 2024. Distillates, encompassing diesel and heating oil, are vital for transportation, industrial use, and seasonal energy demands.
Despite a slight weekly dip, retail diesel prices have stayed high, with the national average reaching $5.257 a gallon on August 10, down from $5.348 the previous week. This price remains significantly above the $4.578 average recorded on July 6. In Europe, fuel markets face similar pressures, with margins for low-sulfur gasoil rising sharply. The premium over crude oil hit a record $74.66 a barrel on July 30, as finished diesel commanded higher prices in the market.
Refinery shutdowns contribute to a global diesel shortfall
Multiple refinery disruptions have further diminished the global supply of diesel available to international markets. A recent attack damaged a refinery in Russia’s Tatarstan region, compounding the decline in processing activity within the country. Meanwhile, Saudi Arabia’s Jazan refinery has remained offline since July 27 following an earlier attack, removing another source of refined products from international trade. During June, refinery runs in several producing regions had already fallen below last year’s levels, reducing the volume of fuel entering global markets.
Export restrictions have added to the constraints, with Russia extending restrictions on gasoline and diesel exports through January 31, 2027. Meanwhile, vessel traffic through the Strait of Hormuz has significantly decreased, affecting Middle East shipments. China has also reduced its supply of refined fuels amid weakened domestic refinery activity. The European Central Bank reported diesel pump prices near €1.98 per litre in the third week of July, with higher refining margins accounting for a larger share of retail fuel costs.
US refining activity remains robust despite low inventories
American refiners have processed record volumes of crude oil, yet diesel inventories have not recovered to typical seasonal levels. Crude input during the first seven months of 2026 reached their highest point since 2019 for that period. Refinery utilization rates have stayed high, supported by increased processing margins. Nonetheless, distillate stocks at the start of August were at their lowest for this time of year in nearly thirty years. This inventory shortfall coincides with reduced product flows from several overseas refining centers.
Crude oil prices also gained on Wednesday, with Brent near $89.81 a barrel and West Texas Intermediate around $84.08. The pressure on diesel prices is more driven by shortages of finished fuels than crude supply alone. Diesel supports essential sectors such as trucking, agriculture, construction, and manufacturing across both regions. The combination of limited U.S. inventories, high European refining margins, refinery outages, and export restrictions continues to sustain a tight global market for diesel and other middle-distillates.
