US Diesel Prices Hit Record High, Squeezing Economy

Diesel prices in the United States have surged to an all-time high of $5.85 per gallon, according to AP News, as the six-month US-Israel war against Iran continues to disrupt global fuel supplies. The record price, which surpassed the previous peak of $5.82 set in June 2022, threatens to ripple through the American economy by raising costs for food, consumer goods, and transportation across nearly every sector.

What’s Driving the Surge

The price spike stems from a convergence of supply disruptions that began when the US and Israel launched their war against Iran on February 28. Diesel prices are now nearly 56% higher than the $3.76 per gallon national average recorded before hostilities began, according to AAA data cited by AP News.

The conflict has severely disrupted shipping through the Strait of Hormuz, a critical waterway through which roughly one-fifth of the world’s oil supply flows. Most tanker traffic has been bottlenecked, and Iran has re-imposed restrictions on the strait after Washington refused to lift its counter-blockade. Brent crude, the international oil benchmark, was trading above $95 per barrel on Friday, up from roughly $70 before the war began.

Adding to the strain, Ukrainian drone attacks on Russian refineries have led Moscow to ban diesel exports through September 30, according to USA Today. Around 900,000 barrels per day of diesel and 350,000 barrels per day of jet fuel moved through the Gulf before the war, equivalent to roughly 10% and 20% of global seaborne supply respectively.

Record-Breaking Numbers

The national average diesel price hit $5.820 per gallon on Thursday according to fuel price tracking service GasBuddy, beating the previous record of $5.819 set on June 17, 2022, as reported by USA Today. Average diesel prices have remained above $5 per gallon since July 15, and 2026 is on track to be the most expensive year for diesel in US history, according to Patrick De Haan, head of petroleum analysis at GasBuddy.

Regular gasoline has also climbed sharply, averaging $4.15 per gallon compared with $3.20 at this time last year. AAA noted that gas has never been above $4 per gallon on Labor Day before, as CBS News reported. The motor club stated: “Even though gasoline demand decreases this time of year, typically bringing down gas prices, this year is different due to the high cost of crude oil.”

US diesel inventories are at historically low levels, with distillate stocks averaging their lowest August levels since 1982, according to Energy Information Administration data. The East Coast has been hit particularly hard, with distillate inventories falling to a record low of 19.3 million barrels in the week ending August 28. The US diesel crack spread, a measure of refining profitability, surged to a record intraday high of $108.02 per barrel on Wednesday.

The Economic Toll on Consumers

The impact of high diesel prices extends far beyond the fuel pump. Diesel powers the trucks, trains, and ships that move goods across the country, and fuel accounts for roughly 15% to 30% of the total cost of food, according to the Independent Grocers Alliance.

David Ortega, a professor of food economics and policy at Michigan State University, told AP News that perishable items requiring refrigeration during transport are often the first to see price increases. In July, overall US grocery prices were up 2.7% year-over-year, but seafood prices rose 7% and fresh fruit prices climbed 4.9%.

“Early on, much of the cost increase gets absorbed along the supply chain through existing freight contracts and retailer margins,” Ortega said. “But as contracts reprice and fuel surcharges take hold, more of that cost makes its way to the grocery store.”

Ajesh Kapoor, CEO and founder of trucking technology company SemiCab, emphasized the breadth of the impact: “Diesel price has a very, very direct impact on everything that moves on pretty much any mode.”

Businesses Pass on Costs

Major carriers and retailers have already begun passing costs to consumers. Amazon rolled out a temporary 3.5% fuel and logistics surcharge on some third-party sellers in April, as AP News reported. The United States Postal Service imposed its first-ever 8% fuel surcharge on package deliveries, effective April 26 through January 17, 2027, according to CNBC. UPS and FedEx have also increased fuel surcharge rates and introduced temporary Middle East surcharges, as detailed by Supply Chain Dive.

Susan Bell, senior vice president of downstream research at Rystad Energy, told CBS News that the everyday consumer will feel the effects: “Think of the groceries that get shipped around the nation, and fruits and vegetables that come from California and move by truck or rail. It’s inflationary.”

The total consumer burden has been staggering. According to the Brown University Iran War Energy Cost Tracker, Americans have paid approximately $94.5 billion extra for gasoline and diesel since the war began, or roughly $721 per US household.

Political Fallout Ahead of Midterms

The diesel price spike adds to significant political challenges for Republicans ahead of November’s midterm elections, when the party will be defending narrow majorities in both houses of Congress. Al Jazeera reported that a late-August Reuters/Ipsos poll showed only 31% of Americans support the war, compared with 63% who oppose it. President Trump’s approval rating has fallen from 40% to 33% since the outbreak of hostilities.

A Politico poll conducted in August found that 61% of Americans believe the Iran war has made life more expensive for their families. West Virginia Sen. Shelley Moore Capito, a member of Republican leadership, told NOTUS that constituents are “just wearing out on it,” describing a “fatigue factor” around the prolonged conflict.

Senior advisers to Trump are seeking to prevent the conflict from returning to all-out war before the November 3 polls. However, analysts warn that Iran may have its own incentives to escalate. Trita Parsi, executive vice president of the Quincy Institute for Responsible Statecraft, told Al Jazeera that Iranian officials appear to believe Trump ultimately intends to restart the war on a larger scale after the midterms, creating a potentially dangerous calculation for Tehran to strike first.

What to Watch For

Industry experts warn that prices could climb further as seasonal demand picks up. Farmers harvesting crops in the Northern Hemisphere and preparations for planting in the Southern Hemisphere are expected to boost diesel consumption in the coming months. Demand for heating oil, a similar distillate fuel, also typically rises ahead of the winter heating season.

“We’re entering a key period for diesel consumption with the lowest inventories on record for early September,” David Russell, Global Head of Market Strategy at TradeStation, told USA Today. “Farmers and truckers typically use more diesel in the autumn, which raises the stakes for the current crisis and increases the risk of sharper price increases.”

President Trump met with US oil refiners earlier this week to discuss increasing capacity, and the administration has struck a deal with Venezuela to gain control of about 65 billion barrels of its proven oil reserves. However, energy experts caution that it could take years for those fields to yield enough crude to meaningfully affect fuel prices.

Neil Atkinson, energy analyst and senior fellow at the National Center for Energy Analytics, offered a stark assessment of the current situation: “This cannot go on forever.”

For American households already feeling the pinch of higher grocery bills and shipping costs, the question is how much longer the supply disruptions will last — and whether relief will come before the November elections or after.
