US Diesel Hits a Record $6.51 a Gallon

US diesel hit a record high of $6.51 per gallon on Monday¹. Agriculture Secretary Brooke Rollins said President Trump called her that day to discuss diesel prices¹, and she told reporters the call concerned the diesel issue⁴. The retail average has topped $6.50 a gallon, a spike attributed to compounding geopolitical conflict and supply chain disruption⁷. Two separate global conflicts are disrupting fuel supply chains, and economists and supply chain analysts are watching the consequences⁶.

The immediate constraint is refining and pipeline capacity. Energy Secretary Chris Wright expects a damaged pipeline back in operation within days, but one commodity strategist wrote that trading estimates range up to 8 weeks and warned of a deficit no handshake can refill². A global refinery crunch is pushing diesel prices to new records³.

The export-ban fight

Big agriculture and big oil are now head to head over a diesel export ban¹. Senator Chuck Grassley has asked why the president does not embargo diesel exports as presidents did in the ‘70s, while Senator Bernie Sanders cited pump prices of $4.44¹¹. A key ally is urging Trump to back US farmers amid anger over rising prices⁴.

The administration is not united. Energy Secretary Chris Wright and Interior Secretary Doug Burgum oppose an export ban as a bad idea that would ultimately backfire³. Burgum, at a G20 meeting in Houston last week, said the administration would consider an export ban if it thought that would actually work⁹, and has previously said it would not⁵. The Texas Oil and Gas Association’s president argues that a diesel ban today means a weaker America tomorrow⁹. Republicans are sweating over the price of diesel, with Treasury Secretary Scott Bessent also weighing in⁵.

What to watch

The pass-through runs through freight and farming. Diesel above $6 is a shock to US farms, with a global shortage threatening 2027 harvest costs; the eventual impact will depend on commodity prices, yields, regional fuel availability and how long the geopolitical disruptions last⁸. Scripps News is publishing an interactive tool on what the record price means for households⁶.

Departmental business has continued alongside the price fight, with Rollins announcing on Friday that New Mexico has USDA approval to join the State Meat and Poultry Inspection Program¹⁰. The open questions are whether the administration moves from considering an export restriction to imposing one^3,9, and how quickly refining and pipeline capacity returns, where official and trading estimates are days apart from each other².
