Record $5.85 Diesel Price Hits Valley Shoppers Hard

Aspen —The number is ugly. $5.85. That is the new national average for a gallon of diesel. It happened on Friday. It is a record.

Vail Daily reported the spike, tracing it directly to the six-month war with Iran. The conflict has choked the global flow of fuel. Tanker traffic is bottlenecked in the Strait of Hormuz. Brent crude, the international standard, jumped from roughly $70 a barrel pre-war to more than $95 on Friday.

Diesel is the blood of American freight. It powers the trucks, trains, and boats that move everything from clothing to furniture. When diesel spikes, transportation costs follow. Some businesses have already reacted. They are adding fees to online orders and mailed packages. Shoppers will likely see this "sticker shock" on store shelves soon.

The grocery aisle feels the strain first. Produce, meat, and perishables require frequent hauling and restocking. Farm equipment running on diesel adds another layer of cost. It takes time for these expenses to trickle down to the consumer. But experts warn that price hikes will mount as long as diesel stays expensive. For folks in the valley, this hits close to home. The cost of getting fresh produce from local farms into our pantries will rise as haulers pass on their fuel bills.

Context matters. American diesel prices are now nearly 56% higher than before the U.S. and Israel launched their war against Iran in late February. Back then, the national average sat at about $3.76 per gallon, according to AAA.

Gasoline is rising too, though slower. The average price is $4.15 a gallon, up from $3.20 at this time last year. AAA notes that gas has never been above $4 a gallon on Labor Day.

Politically, this is a headache for Republicans ahead of November’s midterms. Many voters are already sour on President Donald Trump’s management of the economy and the fallout from the war he launched. AP-NORC polling this summer showed 2 out of 3 U.S. adults disapprove of how Trump is handling the economy.

History offers a grim comparison. The last time businesses and drivers saw sky-high fuel prices was in June 2022. Diesel reached nearly $5.82 a gallon on average, months after the Ukraine war began and sanctions hit Russia.

But inflation changes the math. Ahead of the 2008 financial crisis, diesel hit about $4.74 a gallon. Adjusted for inflation, that equates to $7.20 in 2026, according to government data. The 2022 record of nearly $5.82 would be
