Yes. On Sept. 11, 2026, the U.S. national average retail diesel price reached about $6.06 a gallon, according to AAA data reported by CNBC — the first time the nationwide average has crossed the $6 mark. Truckers and farmers were paying roughly 63% more than a year earlier, and California’s average was near $8 a gallon.
Analysts tied the surge to supply disruptions from the Iran war and Ukraine’s strikes on Russian refineries, which have constrained diesel exports and left U.S. refining near full utilization. Higher diesel costs typically feed into food, freight, and consumer-goods prices because trucks, trains, ships, and farm equipment run on the fuel.
