Trump administration nears 90-day diesel export ban despite cabinet opposition

A ban on US diesel exports would further tighten a global middle-distillate market already under strain, leaving European and Asian buyers most vulnerable as cargoes intended for those regions are kept within the US. The near-term outcome would likely be a market that splits: domestic diesel prices in the US soften while overseas benchmarks strengthen, widening the differential between US and international product prices. Over a longer horizon, reduced refinery runs in the US would slightly lower crude demand while providing support for gasoline and jet fuel. Since damage from the Iran war has already hit Middle East refining and constrained product supply, traders are likely to view any announcement as an added source of instability in refined products rather than a permanent solution.

Historically high diesel costs and an approaching midterm election are driving the White House toward a 90-day export prohibition that Energy Secretary Wright has warned would be counterproductive, and a decision could come within days.

Summary:

• The White House is putting together a plan to prohibit US diesel exports for 90 days, according to Politico, while the legal framework is still being finalized.
• Trump is reportedly leaning toward making an announcement by the end of the week, and Energy Secretary Wright informed energy CEOs on Tuesday evening that a ban could come within days.
• Wright, Treasury Secretary Bessent and Interior Secretary Burgum have opposed a full ban; Wright suggested publicly that voluntary alterations to export destinations be considered instead, and a White House official dismissed the report.
• US diesel is averaging about $6.50 per gallon, according to AAA, an increase of roughly 90 cents over the past month and more than $2.80 year-over-year, driven by the Iran war and Ukrainian attacks on Russian refineries.
• Senator Grassley's support over the weekend prompted a surge of demands from farm-state Republicans, with the midterm elections less than seven weeks away.
• Such a ban would mark the first US energy export restriction since 2015, and the industry warns that it could eventually raise fuel prices by prompting refiners to reduce output.

The Trump administration is nearing a 90-day prohibition on US diesel exports, with the president reportedly leaning toward announcing the measure by the end of this week, according to a Politico report that cites five sources familiar with the discussions. The initiative is moving forward even as senior cabinet officials, refiners and some GOP lawmakers express opposition, and it builds on the proposal that we first reported earlier this week and then revisited in a follow-up piece.

Multiple indications suggest growing momentum for the measure. On Tuesday night, Energy Secretary Chris Wright called energy chief executives to inform them that a 90-day halt was probable within days, according to an energy adviser to the president, who noted the situation is still volatile. That adviser stated the turning point occurred last weekend when Iowa Senator Chuck Grassley, a prominent farm-state voice, publicly endorsed a ban because of the impact of high diesel prices on agricultural income, which triggered a flood of similar requests from other farm-state Republicans. An oil industry executive who has spoken with senior White House officials indicated that Trump seems ready to view any consequences as an issue to handle in December, as political pressure over fuel prices now outweighs the more cautious voices.

Significant opposition remains. According to people familiar with the discussions, Wright, Treasury Secretary Scott Bessent and Interior Secretary Doug Burgum have all opposed a full ban. In public remarks on Wednesday, Wright argued that since refineries produce diesel together with gasoline and jet fuel, blocking exports from the world's largest diesel exporter would eventually force production cuts once storage capacity is reached, pushing up prices for other fuels. At another event, he indicated that exports would not cease entirely, instead suggesting possible voluntary adjustments to the destinations of US diesel shipments. A White House official called the report fake news, and the legal pathway for any ban is still being developed.

The pressure originates from pricing. According to AAA, the average US diesel price was approximately $6.50 per gallon on Wednesday, an increase of about 90 cents over one month and more than $2.80 compared to a year ago. The Iran war, which started in February, has harmed refineries in the Middle East and cut regional oil flows, while Ukrainian attacks on Russian refineries have further constrained supply.

A ban would represent the first limitation on US energy exports since a long-standing crude export prohibition was removed in 2015. Redirecting cargoes intended for Europe and Asia back into the domestic market could initially lower US prices in certain areas, but refiners would likely reduce output after losing a key export market, eventually driving prices higher. A commodities economist cautioned that a ban would exacerbate already severe global diesel shortages and increase prices outside the US in the short run, while ultimately being counterproductive. An external adviser to the administration also expressed worries that a ban could be extended multiple times and create a precedent for state intervention in energy markets.

With midterm elections less than seven weeks off, the final decision may hinge on whoever is the last person to speak with Trump. Markets will be watching to see whether any announcement this week comes as a complete 90-day ban or the more limited, voluntary redirection that Wright has outlined.
