Goldman Sachs warns US diesel export ban would spike gasoline prices

Key points

• Goldman Sachs estimates a diesel export ban would cut US diesel prices by $0.25/gallon weekly until storage capacity is reached.
• Once storage fills, Goldman predicts US gasoline prices will rise by $0.30/gallon weekly due to shared refinery production.
• The ban would increase European diesel prices by approximately $3 per barrel, or 2% of current prices, as Europe is the largest buyer of US energy commodities.
• An emergency inventory release could mitigate about 50% of the price increase in Europe, according to Goldman.
• US diesel prices recently hit a record high of $6.53 per gallon, averaging around $6.50 on Friday, driven by geopolitical conflicts in Ukraine and the Middle East.

Background

This debate follows weeks of rising fuel costs, with US diesel prices reaching record highs in September 2026. Farm-state Republicans have pushed for an export ban to help agricultural workers, while the White House has weighed restrictions rather than an outright ban. Previous warnings from the EU and UK highlighted concerns that a US ban would trigger severe price spikes in Europe and Latin America, where US diesel accounts for a major share of imports.

How outlets are covering it

Goldman Sachs and Morgan Stanley analysts agree that a US diesel export ban would backfire by raising gasoline prices due to the interdependence of refinery outputs. However, they differ slightly in emphasis: Goldman focuses on the specific weekly price increases for gasoline and the eventual rebound of diesel prices once the ban lifts, while Morgan Stanley highlights the broader global feedback loop and adverse downstream reactions. CNBC notes that European traders largely doubt the US will implement a ban, citing the difficulty for US oil companies, whereas the American Petroleum Institute (API) strongly opposes the move, arguing it would compound refining challenges. Conversely, farm-state Republicans support the ban to ease record-high costs for agricultural workers ahead of the midterm elections.

Why it matters

The potential diesel export ban could significantly impact global fuel markets, raising gasoline prices in the US and diesel prices in Europe. This move, driven by political pressure ahead of the November midterms, risks exacerbating a global fuel crisis already strained by conflicts in Ukraine and the Middle East. The decision could also affect US farmers and households facing higher costs, while European nations, which rely heavily on US diesel imports, may face severe price spikes and supply shortages.

What to watch

The White House is expected to make a decision on the diesel export ban in the coming weeks, with Energy Secretary Chris Wright indicating that restrictions are being considered. If implemented, the ban would likely last 90 days, after which diesel prices are expected to rebound. The outcome will depend on the balance between political pressure from farm states and opposition from energy industry groups and European allies.
