Analysis: U.S. Diesel Export Ban Risks Gasoline Shortage

   VIENNA (DTN) -- The implementation of a U.S. diesel export ban to tame 
surging retail prices is not only doubtful to achieve the desired effect, but 
carries every potential to make other fuels more expensive and less available.

   The U.S. is sitting on a sizeable diesel surplus, one that is baked into 
domestic demand and refining fundamentals. Averaged over the year, diesel and 
heating oil production outpaces demand by around 1.1 million bpd. In absence of 
an export outlet, this large surplus would result in crashing crack spreads, 
forcing refiners to drastically throttle runs. Less crude processing, in turn, 
means less production of not just diesel, but all refined products. Gasoline 
would be the fuel most impacted, given that it represents the by far largest 
share of U.S. refiners' output.

   Gasoline Supply Shock

   Experts estimate that the consequent reduction in crude oil net inputs would 
amount to anywhere from 1.5 to 2 million bpd. Last year, domestic refinery 
gasoline yields averaged just shy of 46%, according to U.S. Energy Information 
Administration data. Incentivized by the outsized surge in diesel and jet fuel 
crack spreads, refiners have since the start of the Hormuz supply disruption 
tweaked operations to maximize production of these products beyond seasonally 
normal adjustments, pushing gasoline yields to a post-COVID low of 43.8% in 
July, the latest month with available data. In the best-case scenario, and 
ignoring a not unlikely return to pre-war yields, a 1.5 to 2 million bpd 
reduction in crude oil runs equates to a drop in nationwide gasoline supply to 
the tune of 650,000 to 900,000 bpd.

   Import Dependence

   The sudden loss of 7-10% of gasoline supply would send shockwaves through a 
market already plagued with depleted inventories and high prices, and is just 
large enough to potentially render the country import dependent to meet 
domestic gasoline demand. The U.S. has been a net exporter of gasoline for the 
past 16 years, with gasoline exports outpacing imports by 654,000 bpd last year 
and 725,000 bpd in the first seven months of 2026.

   A higher need for imports, especially at a time when international supply is 
more restricted than usual, means higher prices at the pump. For already import 
reliant regions like the U.S. East Coast, the unintended consequences of a 
diesel export ban may even go beyond surging retail prices. This year's global 
supply crunch has resulted in a prolonged import dearth, with gasoline receipts 
in the region clocking in 200,000 bpd below typical levels, a 30-40% reduction 
depending on the time of year. This phenomenon contributed to a much 
steeper-than-usual decline in gasoline inventories, which are currently 9% less 
well stocked than at the same time last year, and nearly 12% below the seasonal 
five-year average.

   Realpolitik

   Risking higher gas prices in return for a potential reduction in diesel 
costs may not be a recipe for electoral success one month ahead of the 
midterms. The White House may instead be using the specter of a diesel export 
ban as leverage on the geopolitical front. On Friday, one day after the Trump 
administration threatened European countries with cutting off flows of U.S. 
diesel unless they released fuel from emergency stockpiles, the EU was 
considering the joint release of 50 million bbl of diesel, which would, at 
least temporarily, ease the global supply tightness and associated high prices.
