Trump’s Diesel Export Plan Could Raise Prices in the Long Run

President Donald Trump’s proposal to curb diesel exports could fail to produce lasting price reductions, as US refiners could reduce production in response to an oversupply in the domestic market, Sean Williams reported for Motley Fool.

US President Donald Trump has proposed restricting diesel exports as the administration seeks ways to reduce record-high fuel prices.

The trailing 12-month inflation rate reached a three-year high of 4.2% in May, while energy prices have remained elevated amid disruptions linked to the conflict involving Iran and the Strait of Hormuz.

AAA reported that diesel reached a record $6.53 per gallon on Sept. 22, up roughly 77% from a year earlier.

Trump has proposed restricting diesel exports as a way to increase domestic supply and lower prices.

However, the effects of an export ban would be more complicated than a simple increase in domestic supply. The US is a major exporter of distillate fuel, and EIA data show that US distillate exports have remained elevated in 2026.

The EIA also projects that low distillate inventories will continue contributing to higher domestic diesel prices through the end of the year.

Energy Secretary Chris Wright has said a diesel export ban would be ineffective and could be counterproductive, while refiners and industry groups have warned that restricting exports could reduce refinery operations and create supply problems.

Reuters reported that US refineries were operating at about 94% of capacity and that the administration was considering other measures to ease fuel prices.

A partial or full export ban could initially increase the amount of diesel available domestically, potentially putting downward pressure on prices. But if refiners responded by reducing output, that effect could diminish.

At the same time, limiting US exports would reduce supplies available to international markets and could contribute to higher global prices. The EIA reported that US distillate exports were 1.331 million barrels per day in the week ending Sept. 18.
