Diesel Prices Hit Record $6 Per Gallon, Stoking Inflation

Five California diesel pumps showed $9.999 per gallon, the ceiling their displays can handle. GasBuddy petroleum analyst Patrick De Haan reported the readings; the specific stations were not identified.

• $7.76 per gallon: California's diesel average as of Sept. 9, per EIA.
• 55 cents: California's diesel price increase in a single week.
• $5.98 per gallon: the new national diesel average, per AAA, topping the 2022 record.
• 98%: U.S. refinery utilization rate, leaving little buffer for supply shocks.

Why it matters: Higher diesel costs move through the economy via trucking, rail, farming, and construction — sectors that touch nearly every consumer good.

• Thomas Ryan, a senior North American economist at Capital Economics, said businesses are likely to start passing costs to consumers within months if prices hold.
• Producer prices in August showed more than a third of goods inflation came from diesel, which rose 24.1% that month, per the Department of Labor.
