The average cost of diesel fuel in the United States reached an unprecedented high on Friday, climbing to roughly $5.85 per gallon, according to AAA. That marks a staggering 58% increase from the same time last year, when diesel averaged about $3.71, and a nearly 9% jump from a month ago, when the price was around $5.37.
The surge is directly linked to the ongoing conflict with Iran, which has effectively shut down the Strait of Hormuz, a critical artery for global crude oil shipments. The disruption has tightened worldwide supply and sent energy prices climbing, a development that is now rippling through the American economy.
Because diesel is the primary fuel for commercial delivery trucks, the spike is expected to push up the cost of everyday goods, from groceries to retail items. This adds another layer of inflationary pressure on households already grappling with higher prices at the pump.
The record diesel price is a fresh political headache for the Trump administration, which has sought to downplay the domestic economic fallout from the war with Iran as the midterm elections draw near. The president's approval rating has taken a hit amid rising fuel costs, and a July poll from The Associated Press and NORC found that 66% of Americans disapproved of his handling of the economy.
In a bid to counter the political damage, President Trump directed the Department of Justice in June to investigate alleged gas price gouging. On Friday, White House spokesperson Taylor Rogers issued a statement defending the administration's approach, saying the president remains committed to "unleashing American energy dominance."
"This week the President met with nearly a dozen refiners to discuss ways to expand our refining capacity, which will lower prices at the pump," Rogers said. "As the U.S. military fully degrades the terrorist Iranian regime's ability to attack shipping vessels, oil and gas prices will fall back to pre-conflict levels."
The conflict, now in its sixth month, has also driven up regular gasoline prices. The national average for standard gas was about $4.18 per gallon on Friday, up from roughly $3.20 a year ago, according to AAA. In August, fuel price tracker GasBuddy reported that regular gas prices were the highest they had ever been this late in the year. Patrick De Haan, the group's top petroleum analyst, noted that the national average had never exceeded $4 per gallon after Aug. 12 in any prior year.
As the administration works to manage the economic and political fallout, the rising energy costs are becoming a central issue in the midterm campaign. The president's approval rating remains at a record low, with cost concerns dominating voter sentiment. Meanwhile, some voices are calling for more drastic measures to end the conflict, including a draft to spark antiwar protests. The administration, however, is betting on its military strategy to stabilize prices, and the president is set to press refiners on pump prices as the elections approach.
With no immediate end to the crisis in sight, consumers and businesses alike are bracing for continued volatility in energy markets. The record diesel price is a stark reminder of how geopolitical turmoil can quickly translate into financial strain at home.
