US diesel price tops $6 a gallon
Archived — this story has rotated out of today’s deck. It is kept here in full.
The gist
US diesel topped $6 a gallon for the first time, with records in 28 states.
It raises delivery, farming and heating costs, feeding inflation across the economy.
Background
Diesel prices have climbed as crude oil surged above $100 a barrel amid intensified fighting between the U.S. and Iran and Ukrainian attacks on Russian refineries, which squeezed fuel supply. Diesel inventories are 13% below the five-year average, and analysts say refining constraints may persist. Because diesel powers trucking, rail, farming and construction, higher prices ripple into groceries, deliveries and household goods.
How it unfolded
- Sep 8, 2026Brent crude crossed $100 a barrel and has climbed since.
- Sep 10, 2026The US national average diesel price surpassed $6 a gallon for the first time, according to GasBuddy; AAA put it at $5.98, up 61% from $3.71 a year earlier.

Who’s saying what
- Analysts
- GasBuddy's Patrick De Haan called record diesel prices a "silent killer" for the economy that will reignite inflation up and down the supply chain.
- Public
- A North Carolina farmer said diesel now costs about twice what it did a year ago, and a local truck driver said the cost is passed down to businesses and then to consumers.
Still unverified
A social media post attributed the price surge to "Donald Trump's war with Iran," and reports describe the conflict as a "U.S.-Israeli war on Iran"; these characterizations are not confirmed by the cited sources.
