Overview
- This Labor Day weekend the U.S. national average for regular gasoline rose to about $4.13–$4.15 per gallon, a record for the holiday, while diesel hit all‑time national highs around $5.85–$5.88 per gallon.
- Diesel's surge matters beyond the pump because trucks, trains and farm equipment run on distillates, so higher diesel is already driving up freight and farm fuel bills and will likely raise food and shipping costs over coming months.
- Analysts link the jump to renewed U.S.-Iran fighting that has disrupted tanker traffic through the Strait of Hormuz, plus attacks and export curbs that have reduced global refined‑product flows.
- Domestic supply can’t easily fill the gap: U.S. refineries are running near capacity, exports of refined fuel are elevated, and distillate inventories sit unusually low for the season.
- Rising fuel costs are creating clear political and economic pressure before November, with some GOP operatives and internal polling saying voters blame President Trump’s war policy, and relief dependent on de‑escalation or policy changes that boost supply.
