U.S. diesel prices reached a record $6.53 per gallon, increasing cost pressure on freight, trucking and agriculture as the Iran conflict raises concern over energy supplies.

The price was up 74% since the conflict began. The latest price is the highest nominal level in the historical series and the highest inflation-adjusted level since 2022.

Diesel is a key fuel for freight carriers, trucks and agricultural equipment, leaving transportation and farming businesses exposed to higher operating costs. The price surge comes amid concerns that the conflict could tighten energy supply chains.
