U.S. diesel prices hit another record Friday, surging past $6 a gallon nationally amid escalating Middle East conflict and refinery disruptions.
AAA Data
The nationwide average for a gallon of diesel climbed to $6.05, representing an increase of more than 60% over the previous year, according to data from AAA. Diesel prices in the U.S. have hit a painful new milestone for the transportation industry: $6 a gallon, a surge experts said is likely to have ripple effects for consumers as businesses pass on their higher energy costs. The national average of $6.05 represents an increase from $5.85 the previous week and $3.70 from the same period last year, based on motor club AAA data.
While regular gasoline prices have also risen—hitting an average of roughly $4.30 a gallon—analysts note that diesel is the fundamental fuel of commercial transit. It powers the freight trucks, locomotives, agricultural equipment, and construction machinery behind almost every physical product sold in the United States.
Supply Shocks and Middle East Conflict
The price surge stems from disruptions to the global distillate pool, driven largely by the ongoing war between the United States, Israel, and Iran. That conflict has effectively closed the Strait of Hormuz, a critical chokepoint through which roughly one-fifth of the world’s oil transits during peacetime. The war in Iran had already sent fuel prices soaring as Tehran essentially closed the Strait of Hormuz, a critical waterway through which a fifth of the world’s oil transits during peacetime.
Yemeni Houthis and Saudi Crown Prince Mohammed bin Salman
At the same time, geopolitical and military friction has compounded fuel scarcity globally. Ukrainian drone strikes have damaged Russian refining infrastructure, prompting Moscow to impose a sweeping diesel export ban. In Yemen, the Houthis have seized control of the Bab al-Mandab Strait and the port city of Mokha, adding another layer of risk to maritime shipping lanes in the Red Sea. Yemen’s Houthis have seized the key Red Sea port of Mokha, according to numerous reports, as well as the strategic island of Perim. They also seized the last two islands that were not under their control in the Bab el-Mandeb Strait, a military official in the Yemeni government told the AFP news agency. The moves make it easier for the Houthis to target ships transiting the crucial strait for Saudi Arabian oil exports. Saudi Crown Prince Mohammed bin Salman has personally pressed President Trump to take military action against the Houthis as forces have advanced rapidly along Yemen’s Red Sea coast, two sources familiar with the matter told CBS News, adding Mr. Trump and the crown prince have spoken multiple times in recent days about the escalating situation. The Iran-backed militant group took over Yemen’s port city of Mokha, an area vital for control of shipping via the Red sea, Houthi and Yemeni officials said on Thursday.
Sticker Shock Reaching Farms, Groceries, and Supply Chains
The downstream consequences of six-dollar diesel are moving rapidly from commercial transport into household budgets. Because diesel fuels the heavy machinery used on farms, the trucks hauling perishable items, and the trains distributing consumer goods, businesses are passing higher energy costs down to consumers through delivery fees and elevated retail prices. The cost of diesel gets into just about everything,
KPMG chief economist Diane Swonk said in a recent interview. From running a farm … [to the] cost of food, but also everything across the economy that’s shipped,
she said. When diesel prices rise, everything gets that extra fee tacked onto it.
Swonk predicted that the high cost of diesel will be an inflationary problem
for months to come.

Groceries face immediate upward pressure, particularly fresh meat and produce that require frequent restocking and intensive distribution. Shoppers may feel more and more sticker shock, particularly in the grocery aisle. Perishable foods, like meat and produce, face one of the most immediate strains of expensive diesel because they need to be hauled in and restocked frequently — or may be harvested using farm equipment powered by the fuel. U.S. stocks are rebounding Friday and clawing back much of their losses for the week as U.S. stocks jump after oil prices ease and inflation update comes in near expectations.
