Treasury Secretary Scott Bessent confirmed the White House is studying whether to block diesel exports, a move that could reshape energy markets but faces sharp opposition from the oil industry.
Bessent made the disclosure Tuesday at the United Nations, on the sidelines of a bilateral meeting between President Trump and Ukrainian President Volodymyr Zelenskyy. The Treasury secretary told reporters the administration is evaluating whether the country's refining capacity can support a full or partial ban on diesel shipments abroad.
"We're examining whether it's feasible in terms of the overall refining capacity and whether a full or partial ban would work," Bessent said.
Trump himself left little doubt about where he stands. The president told reporters he has pushed for the ban inside the administration and that a decision would come soon.
"I've said let's not send out the diesel. We make a lot of diesel."
The remarks land at a moment when American drivers, truckers, and farmers are absorbing the worst diesel prices on record. AAA data put the national price at $6.53 a gallon, roughly $3 higher than the same period last year. In California, drivers face $8.44 a gallon. At the wholesale level, diesel traded at approximately $207 a barrel Tuesday, more than $100 above the price of crude oil.
The price explosion did not happen overnight. Conflicts in Eastern Europe and the Middle East have steadily choked global refining output. Ukraine's strikes on Russian refineries forced Moscow to impose its own diesel export ban to keep domestic supply flowing. In the Middle East, Iran and its Houthi allies have attacked refineries and threatened tanker traffic through the Strait of Hormuz, tightening product exports further.
American refiners stepped into the gap, and profited handsomely. With global supply short and prices soaring, U.S. producers ramped up diesel exports to overseas buyers, reaping what the reporting describes as "sky-high profits." The result: record volumes leaving American ports while American consumers paid record prices at home.
That dynamic, domestic pain funding foreign supply, is exactly the kind of market distortion that draws political attention. The broader energy cost burden from the Iran conflict has only intensified the pressure on Washington to act.
Sen. Chuck Grassley of Iowa and other Republican lawmakers had already called for a diesel export ban before Bessent's announcement. Their argument is straightforward: farmers filling combine tanks and truckers hauling freight cannot absorb $6.53-a-gallon diesel, and neither can the consumers who pay higher grocery bills and shipping surcharges as a result.
With November midterm elections approaching, the political math is plain. Diesel prices feed directly into the cost of food, consumer goods, and construction materials. Every dollar added at the pump cascades through the supply chain. Diesel's climb past $6.20 a gallon had already handed the GOP an affordability crisis it could not ignore.
The fuel squeeze extends well beyond diesel. Airlines have slashed routes as jet fuel costs surge, and gasoline prices shattered records over Labor Day, hitting American drivers at the worst possible time.
The American Petroleum Institute fired back within hours. Mike Sommers, the oil industry lobby group's CEO, warned in a statement that restricting exports would deepen the very problem it aims to solve.
"Restricting U.S. energy exports would only compound the problem, exacerbating refining challenges and ultimately hurting consumers."
Sommers argued the administration should pursue the opposite approach.
"The answer is more supply and more flexibility, not new restrictions that risk making a difficult situation worse."
The API's position rests on a familiar free-market argument: export bans discourage investment in new refining capacity, reduce the incentive for producers to maximize output, and can trigger retaliatory trade measures from foreign buyers. A Dow Jones Energy analyst echoed part of that logic, noting a ban would offer short-term price relief but risk worse long-term consequences for the market.
That tension, short-term relief versus long-term market distortion, is the core policy question the administration must resolve. And the clock is ticking. Inflation data from August showed prices still climbing across the economy, with energy costs a primary driver.
Bessent's statement confirmed the administration is studying the idea. It did not reveal how a ban would work in practice. Several critical details remain unresolved.
No one in the administration has specified whether the ban would use executive authority or require congressional action. The scope, full ban versus partial restriction, is still under review. Neither the White House nor Treasury has offered a timeline beyond Trump's statement that a decision would come "one way or another." And no official has addressed how much diesel currently leaves the country or how quickly a ban would translate into lower pump prices for American consumers.
The fuel crisis has already rippled into sectors far removed from the highway. Airlines have cut flights heading into the holidays as jet fuel costs eat into already thin margins, a reminder that energy price shocks do not stay in one lane.
Russia's experience offers a cautionary data point. Moscow banned diesel exports only after its own refining infrastructure took direct hits from Ukrainian strikes. The move stabilized Russian domestic supply but removed a major source from global markets, pushing prices higher everywhere else, including in the United States.
A U.S. ban would carry even larger consequences. American refiners are among the world's most productive, and pulling their output from international markets could spike global diesel prices, strain allied economies, and invite retaliation, all while delivering uncertain relief at home.
The API and its allies will argue that the answer is more drilling, faster permitting, and fewer regulatory barriers. Grassley and the Republican lawmakers backing a ban will counter that American consumers should not subsidize foreign buyers while paying record prices themselves. Both sides have a point. The question is which pain the administration is willing to accept.
When American families are paying $6.53 a gallon so that refiners can chase higher margins overseas, the free-market argument, however sound in a textbook, has to compete with a kitchen-table reality that voters feel every time they fill a tank or buy a gallon of milk.
