White House Weighs 90-Day Diesel Export Ban as Energy Sec Warns of Backfire, Global Markets Seize

U.S. diesel futures sank more than 7% and European contracts jumped over 7% Wednesday after Politico reported that the White House is preparing a potential 90-day ban on diesel exports ahead of November's midterm elections, a measure energy officials and analysts say could amplify supply problems rather than ease them.

The proposal remains under discussion with its legal framework unresolved, Politico reported, citing five people familiar with the talks. A White House official dismissed the report as "another fake news story from Politico."

The market split was immediate and stark. While U.S. diesel futures hit an intraday low, European diesel’s premium to Brent crude — the crack spread — surged to more than $95 a barrel, a record in Bloomberg data extending back to 2011. The equivalent U.S. measure weakened.

**Energy secretary publicly opposes ban**

U.S. Energy Secretary Chris Wright publicly rejected the idea Wednesday, putting him at odds with President Trump, who signaled support for the concept on Tuesday and assigned Treasury Secretary Bessent to explore its feasibility.

"The blunt tool of banning diesel exports definitely doesn't work," Wright said at an event in New York, as reported by Reuters. He argued that restricting exports would leave refiners with excess diesel inventories, forcing them to cut output. Lower refinery runs would tighten supplies of gasoline and jet fuel, ultimately driving up costs for consumers and businesses.

Trump’s earlier signal had already roiled European markets, which depend heavily on U.S. diesel. The U.S. has become Europe’s main overseas supplier after the loss of shipments from the Middle East and Russian export curbs tightened global supply. American exports of the workhorse fuel surged to a weekly record near 2 million barrels a day last month, according to Bloomberg.

**Industry and analyst warnings**

The American Petroleum Institute cautioned against the move, saying it could lower U.S. fuel production and damage the global economy. "Restricting exports is not a solution to high prices," the API said. "Removing US diesel from the market could instead result in reduced refinery runs, global economic damage and even higher US prices."

Of the roughly 8 million barrels of diesel traded globally by sea each day, the U.S. supplies about 1.5 million — roughly 20%. An export ban would remove the single largest source from the market.

Barclays refining and midstream analyst Theresa Chen warned clients that a proposed ban would be "detrimental to the US refining complex and unlikely to provide the intended price relief," adding that keeping diesel inside the country does not guarantee it can reach gas pumps.

Goldman Sachs energy analyst Nikhil Bhandari told clients the global refining system will remain stretched through 2027, keeping diesel and gasoline prices elevated.

Apollo chief economist Torsten Slok had earlier warned that record diesel prices could spark a core inflation shock.

**Global supply risks intensify**

Bloomberg macro strategist Michael Ball wrote that while the White House might engineer a brief drop in U.S. diesel prices by limiting exports, it risks creating a bigger supply problem down the road, with distillate stocks at seasonally record lows.

The EIA’s latest data, cited by Zero Hedge, shows Mexico is the largest buyer of U.S. diesel, taking about 220,000 barrels per day (17% of total distillate exports) — though that is down 18% from 2024. Chile is the second-largest destination; Brazil third at roughly 103,000 b/d, well below earlier peaks near 200,000 b/d after Brazil took more discounted Russian barrels following 2022 sanctions. The Netherlands and the UK round out the top five.

Europe is already grappling with the loss of diesel shipments from the Middle East and tightening Russian export curbs. A U.S. ban would hit the region at its most vulnerable moment, with American exports having become a critical supply line.

The political pressure for action is intense. As one person familiar with the internal White House discussions told Politico, granted anonymity to describe the talks: "What has overpowered cooler heads [in the White House] is the absolutely, sky-is-falling, we-have-to-do-something concern about prices at the pump...
