Trump Says He Wants a Diesel Export Ban. His Energy Secretary Says It Won't Work.

President Donald Trump said this week that he wants to ban exports of American diesel fuel to bring down record domestic prices, but within a day the White House was distancing itself from any formal plan, and his own energy secretary was telling industry audiences the idea would backfire. The reversal played out as the national average retail price of diesel climbed to the highest level on record, squeezing farmers heading into harvest, long-haul truckers, railroads and, with winter approaching, home heating oil customers across the Northeast.

Speaking to reporters at the United Nations in New York on Tuesday, where he also met with Ukrainian President Volodymyr Zelensky, Trump said he had already pushed the idea internally. "I've said let's not send out the diesel. We make a lot of diesel," he said. "I've called for it." The remark, combined with a Politico report that the administration was drafting a 90-day export ban, sent refiner stocks lower and set off two days of conflicting signals from Trump's own Cabinet.

By Wednesday, a White House official told reporters the Politico report was not accurate. Energy Secretary Chris Wright was more direct, telling an audience in New York that a blanket ban was not what officials were discussing and warning it would likely raise, not lower, prices at the pump.

The Numbers Behind the Squeeze

The political confusion is unfolding against a backdrop of extraordinary fuel prices. The Energy Information Administration's weekly national average survey put retail diesel at $6.529 a gallon for the week of September 21, up 24.4 cents from the previous week and the highest reading in a data series that stretches back more than three decades. The agency's numbers show diesel is now $2.78 higher than a year earlier. The pain is most acute in California, where the statewide average has pushed past $8.40 a gallon, with some individual stations posting prices just under $10.

The country consumes roughly 4.1 million barrels of diesel a day and exports about 1.5 million barrels daily, a share that makes the United States one of the world's largest suppliers of the fuel even as domestic prices spike. According to AAA figures cited in wire reporting, a gallon of diesel that cost $3.77 in late February, before the war between the United States and Iran began, now costs 73 percent more. In its Short-Term Energy Outlook, published September 9, the EIA forecasts the annual average retail diesel price will ease to $5.07 in 2026 and $4.40 in 2027, but it also projects that distillate inventories will fall below 100 million barrels this month and stay below their five-year low for much of next year, meaning relief is likely to be gradual rather than immediate.

How Diesel Got This Expensive

The price spike traces back to the war that began on February 28, when American and Israeli forces launched a joint air campaign against Iran. A ceasefire in April and a June memorandum meant to end the conflict both collapsed, and by late summer the fighting had settled into what analysts describe as a war of attrition. The Middle East supplies a disproportionate share of the crude used to make diesel worldwide, and the disruption to regional refining and shipping has driven distillate prices up faster than gasoline prices since the war began.

The war in Ukraine has compounded the shortage. Ukrainian strikes have repeatedly damaged Russian refining capacity, and Russia itself restricted diesel exports in July as domestic refinery outages reduced its own supply. With two of the world's major exporting regions constrained at once, global distillate markets have tightened sharply, pulling up prices even in a country, the United States, that refines and exports large volumes of the fuel itself.

A Fractured Response

The price surge has scrambled ordinary partisan lines less than three months before midterm elections that were once expected to hinge on other issues. Senator Chuck Grassley of Iowa has pressed Trump for weeks to act, telling the White House that a temporary embargo would help "family farmers who feed and fuel the world" and comparing it to existing restrictions on chip exports to China. Republican candidates in competitive races have echoed him; in wire coverage of the fight, Iowa Senate candidate Ashley Hinson said her constituents "shouldn't have to foot the bill at the pump or the checkout line for the war in Iran," and economist Joseph Brusuelas of RSM warned that "the price of diesel touches everything in our economy that needs to move, including groceries."

But Republicans from energy-producing states have pushed back just as hard, and the oil industry has warned the White House against acting at all. The American Petroleum Institute's chief executive, Mike Sommers, said restricting exports "would hit an already-tight market with another supply shock," and GasBuddy analyst Patrick De Haan said the fix would be worse than the ailment: if diesel exports were banned, he said, prices could climb toward new records because refiners would have nowhere to sell surplus fuel and would likely cut production, pushing up gasoline and jet fuel prices in the process.

Inside the administration, that same argument has come from Energy Secretary Wright, who has become the most visible internal skeptic of the president's stated position.

"The blunt tool of banning diesel exports definitely doesn't work," Wright told an audience in New York.

Wright argued that restricting exports would eventually force refiners to cut throughput, since diesel that cannot be sold abroad would fill storage domestically, and that a shutdown in diesel production would also curb the gasoline and jet fuel made in the same refining process. Treasury Secretary Scott Bessent has taken a more neutral position, saying only that the administration is studying whether a full or partial restriction would be workable given current refining capacity.

Democratic candidates in several battleground states have used the episode to tie fuel prices directly to the war, rather than to export policy. Kansas Senate candidate Adam Hamilton said of the fighting, "A war has sent up the price of diesel," while Virginia House candidate Elaine Luria has described the fallout as "an expanding economic crisis" for the districts she is campaigning in, according to wire service reporting on the political fallout.

What Happens Next

No policy has been signed, and officials have not settled on one path. A White House denial issued Wednesday rejected the specific 90-day framework reported by Politico, even as Trump continued to describe a ban as something he had personally called for. Wright has said the administration is instead working with refiners on voluntary steps to increase domestic diesel supply while keeping gasoline and jet fuel output flowing, and has suggested a policy announcement is coming within days. The legal mechanism for any mandatory restriction remains unclear; officials have not said whether they would rely on emergency economic powers, national-security authorities tied to the Defense Production Act, or seek congressional action, and any of those routes would likely draw legal challenges from exporters and refiners.

For now, the practical effect of the past three days has been political rather than regulatory: a president publicly at odds with his own energy secretary, Senate Republicans divided along regional lines, and diesel prices that, according to the government's own forecasters, are unlikely to fall substantially before next year regardless of what Washington decides. With midterm elections seven weeks away, both parties are treating the price at the pump, and at the diesel island, as a test of who voters will hold responsible.
