Overview
- Diesel reached an all-time national average of roughly $5.85–$5.88 per gallon over the Labor Day weekend while regular gasoline hit a Labor Day record around $4.14–$4.15, according to AAA and multiple price trackers.
- The price spike traces to the U.S.-Iran war that disrupted tanker traffic through the Strait of Hormuz and to strikes on Russian refineries that cut refined-product flows, which together have kept crude above $90 per barrel.
- U.S. refiners are operating near full capacity—about 98 percent—while distillate inventories are well below year-ago and five‑year norms, limiting the ability to boost diesel output quickly, per EIA data cited across reports.
- Higher diesel raises costs for trucks, farm equipment and freight, which transmits into grocery, delivery and construction prices and could keep inflation and borrowing-cost pressures elevated.
- The White House has met with refiners and the Energy Secretary said demand typically falls after Labor Day, but officials warn that policy steps such as blend-waiver changes or reserve moves offer only gradual relief and political risk remains ahead of the midterms.
