Ed Hirs Warns That Trump’s Diesel Export Ban Will Backfire
October 2, 2026 | Economy, News, Politics, USA
A U.S. diesel export ban could provide only temporary relief for consumers before refiners cut production, University of Houston economist Ed Hirs told Energi Media. He warns that restrictions would also worsen shortages for countries dependent on American fuel.
In an interview with Markham Hislop (see below), Hirs argued that attempts to lower domestic prices by keeping diesel inside the United States overlook how refineries respond to weaker sales opportunities. His warning centres on the possibility that lost exports would lead to lower output, eroding the initial increase in domestic availability.
The debate matters beyond truck stops. Diesel costs affect farming and freight, while households using heating oil face exposure to the same broader pressure on refined fuels.
“The global economy runs on diesel,” Hirs said.
How the diesel fuel crisis spreads
Hirs traced the pressure to disrupted energy trade through the Strait of Hormuz. In his account, countries unable to obtain their usual supplies of liquefied natural gas have switched to fuel oil and diesel, increasing competition for those products.
That links a disruption in gas supply to the cost of moving goods and producing food. Hirs said truckers and farmers were absorbing higher bills, with costs passing through the economy to consumers.
He also pointed to pressure on heating oil users in the northeastern United States. The interview’s central affordability concern was that households can face higher costs even when they do not buy diesel directly.
Why an export ban could backfire
Hirs described the Trump Administration’s proposed approach as an effort to force domestic prices down by preventing diesel from leaving the country.
Refiners, however, would adjust their operations, he argued. Facilities could reduce production or undertake maintenance, limiting the amount of fuel available. Refineries also produce gasoline, creating the possibility that a diesel restriction could affect another politically sensitive fuel.
“They will reduce supply to meet the demand,” Hirs said.
He acknowledged that keeping exports at home could give American consumers some initial relief. But he argued that the benefit would be limited and would not last, while trading partners would lose access to supplies.
Fewer exports leave importers exposed
Discussing China’s pause in diesel exports, Hirs said some Asian trading partners lack the refining capacity to replace those shipments simply by buying crude oil elsewhere.
For those buyers, access to finished fuel matters. Hirs argued that simultaneous restrictions by major suppliers would intensify competition for the diesel still available internationally.
His analysis points to a distinction between changing where existing fuel is sold and restoring the supply disrupted by conflict. Export restrictions can redistribute available barrels while leaving the underlying shortage unresolved.
Higher costs carry political consequences
The conversation also examined the pressure on American farmers and the possible consequences for Republicans in the midterm elections. Hirs argued that higher fuel and fertilizer costs, alongside trade problems, were hurting agricultural producers.
He offered no likely timetable for an end to the energy disruption. For consumers, his warning was that a policy promising cheaper diesel could lose its effectiveness once refiners respond, while leaving import-dependent countries facing an even tighter market.
