The United States is embroiled in a war that has thrown global petroleum supplies into turmoil, all while it confronts soaring domestic diesel prices and faces historically tight inventories. It is also positioned as a crucial diesel supplier to the world, yet there are talks of restricting those exports. This situation is a perfect storm, and Trump is poised to tackle it incorrectly.
Despite Trump's diesel-export idea looking superficially logical — America produces diesel, Americans are paying record prices, so keep the diesel at home — refinery economics make the situation much more complicated and even worse, the timing could not be worse: the diesel crisis is partly a consequence of the Iran war and the disruption of Middle Eastern refined-product supplies. At the same time, Trump is considering a policy that could disrupt the very refining system that is supplying the United States and its allies. Or maybe we should call them conditional allies?
What is happening right now?
A week ago, Trump said that he supports restricting U.S. diesel exports as diesel prices hit records. The administration initially said it was examining whether a full or partial restriction would work. But within a day, Energy Secretary Chris Wright publicly pushed back. He said a blunt export ban “definitely doesn't work” because if refiners cannot export diesel, storage fills, forcing refiners to cut production — and that means less gasoline and jet fuel as well.
Then the White House denied that it was preparing the reported 90-day blanket ban, although the administration is still considering measures to increase domestic diesel availability. Well, at least, this is not yet a settled policy.
Would banning exports lower American diesel prices?
In the first stages, probably yes — but not necessarily by much, and potentially only temporarily. According to Reuters, Goldman Sachs now estimates that an export restriction could initially put moderate downward pressure on U.S. diesel prices. That's the immediate political attraction for Trump. More diesel trapped inside the United States means more domestic supply and downward pressure on the Gulf Coast price. But there's a catch that is fundamental to the petroleum business: You don't run a refinery just to make diesel, Mr President.
Refineries produce a basket of products — gasoline, diesel/distillates, jet fuel, and others. If diesel exports are suddenly prohibited, inventories can build rapidly. Once storage becomes constrained, refiners have an incentive to reduce crude throughput. And then America produces less gasoline and less jet fuel too.
S&P Global's analysis estimates that a complete export ban could eventually force U.S. refinery runs down by roughly 1.9 million barrels per day, about 12% of total U.S. refinery throughput. It estimates gasoline production could fall by as much as 750,000 barrels per day, potentially turning the United States from a gasoline exporter into a net importer during the fourth quarter.
That's the paradox of Trump's plan: A policy intended to make one fuel cheaper could make several fuels scarcer. Now, there is a twist here, because this is where Iran enters the story. The United States isn't experiencing a normal diesel shortage. The international diesel market has been badly disrupted by the Iran war, the damage to Middle Eastern refineries, Ukrainian attacks on Russian refining capacity, and already-low inventories. U.S. diesel inventories are forecast to remain below the five-year average through the end of 2026 and much of 2027.
The EIA says something particularly important: U.S. diesel exports have been unusually high because the rest of the world needs the fuel. Net U.S. distillate exports have been at or near five-year highs throughout 2026. In other words, America isn't exporting diesel because it has made too much of it by accident. The world is buying it because the world has a diesel problem. And the United States has become one of the suppliers filling that hole.
So who gets hurt?
Europe is particularly exposed, and Trump definitely likes it. A U.S. export ban would remove a major source of diesel from the Atlantic Basin precisely when Europe is already short of the fuel. Latin America would also be affected. Analysts quoted by Reuters say the result would likely be higher global diesel prices and greater economic disruption. It would be like Washington would essentially be saying: We have an international energy crisis. We are one of the countries capable of supplying the missing fuel. But, you guys lucked out, because we are going to stop supplying it. Guess what happens now? That might lower the American Gulf Coast price temporarily. But it would raise the world price.
And the United States doesn't exist economically outside the world bubble. Higher European and Latin American diesel prices eventually feed into shipping, agricultural commodities, manufactured goods, and other costs. And this is where I think Trump's idea meets the socioeconomic and political quagmire. Trump is trying to solve a global supply shock with a domestic trade restriction. He knows so much about economics that he fails to see that diesel is not merely a consumer product. He is unaware that it is the bloodstream of the physical economy. Trucks, farmers, construction, mining, railways, ships, even backup generators use it. So, a diesel shock eventually becomes a food-price shock, transportation shock, and inflation shock, everywhere. Fortune made essentially this point today: diesel costs propagate through freight, agriculture, construction and other sectors.
Trump's own energy secretary is saying the policy is wrong
Chris Wright isn't some environmental critic of the administration. He's Trump's energy secretary. Yet he is arguing that an export ban would undermine refinery economics and could increase gasoline and jet-fuel prices. Interior Secretary Doug Burgum has similarly argued that an export ban is unlikely to lower petroleum prices. Wright and Burgum make this more than just another partisan argument by highlighting how an oil-producing superpower should behave during a global energy crisis.
So ask yourelves: Should we maximize domestic isolation — keep American fuel at home, like Trump says — or maximize production and allow American refiners to supply the global market while letting the market determine where the marginal barrel goes?
But also consider today's Iran development. This morning, Brent jumped above $107–108 a barrel after Trump rejected an Iranian proposal to reopen the Strait of Hormuz within seven days. By definition, this development makes the diesel question even more consequential, because the United States is simultaneously navigating a conflict that has strained global oil supplies, contending with unprecedented domestic diesel costs, observing inventories stay at historically low levels, emerging as a vital diesel supplier for the global market, and evaluating the possibility of limiting those exports, creating another world shock.
I'm unsure if the world can sustain Trump's drastic measures, and it’s perplexing why the international community hasn't taken significant action in response. At the very least, we need to confront this extraordinary set of circumstances with a level-headed approach, rather than succumbing to the political pressures emanating from the American administration.
So, what we need is a carefully designed, temporary mechanism to prioritize that domestic supply could provide some short-term relief, particularly in regions physically close to the export surplus. But not a blanket export ban that risks damaging U.S. refining economics, raising gasoline and jet-fuel prices, hurting American refiners and farmers, aggravating allies' shortages and ultimately adding to global inflation. And that's before we even get to the geopolitical cost.
Like, what exactly is the message if Trump is asking Europe and other conditional allies to stand with it against Iran and Russia, while simultaneously cutting off one of their most important alternative diesel supplies?
