How Much Worse Could Diesel Prices Get? Land Line Media Explains
Diesel prices have climbed sharply in the United States and Europe amid refinery disruptions, reduced inventories and geopolitical supply concerns, raising transportation costs and prompting President Donald Trump to consider restricting U.S. diesel exports.
Export restrictions could reshape diesel markets
Trump has said he is “very seriously” considering a ban on diesel exports. Supporters of the measure argue that keeping more fuel in the United States could increase domestic supply and reduce prices for American drivers and fleets.
Energy analysts have warned, however, that an export ban could create significant regional and international disruptions. Patrick De Haan and other market analysts have noted that restricting exports could push global diesel prices higher by reducing supplies available to overseas buyers. The impact also could vary across the United States.
States near major refining centers, including Mississippi and Louisiana, could see short-term relief if more diesel remains in domestic markets. The Northeast, which relies more heavily on imported diesel, could face higher costs over the longer term.
Diesel prices weigh on transportation and industry
Diesel fuels the trucking, agricultural, construction and industrial sectors, as well as school buses and backup generators. Higher prices typically increase fuel surcharges and place upward pressure on freight rates and the cost of consumer goods.
Analyst Tom Kloza said diesel prices often receive less public attention than gasoline prices, even though diesel is closely tied to the cost of transporting and producing everyday goods. He warned that a colder-than-normal winter could add further pressure to fuel markets.
The national average price of diesel was reported to have exceeded $6 per gallon for the first time, reaching approximately $6.52 per gallon in one recent measurement. That compares with an average of about $3.63 per gallon at the beginning of 2025 and a reported February 2025 average of $3.68.
Supply disruptions drive prices higher
Analysts have pointed to refinery outages, reduced inventories, Russian supply restrictions and broader geopolitical tensions as factors contributing to the increase. U.S. diesel inventories were also described as being at their lowest seasonal level since records began in 1982.
Diesel production is affected by the refining process and by the mix of products produced from each barrel of crude oil. Agricultural economist Gregg Ibendahl of Kansas State University said economic pressures and supply constraints can amplify the difference between gasoline and diesel prices.
European markets have experienced similar pressure. Diesel prices in the European Union were reported to be about 40% higher since the beginning of the year, compared with an increase of roughly 29% for gasoline. In the United Kingdom, the RAC reported an average diesel price of 200.01 pence per liter, an all-time high.
Diesel powers about 38% of heavy goods vehicles in the United Kingdom, meaning sustained price increases could affect freight costs and the prices paid for goods across Europe. Analysts say the effects of any U.S. export restriction would depend on how long it remained in place and how quickly refiners and international suppliers could respond.
