Goldman Sachs Models Five Transmission Effects of a U.S. Diesel Export Ban
nashnova research
Trump backed a ban on U.S. diesel exports; Goldman immediately modeled the fallout — diesel drops $0.25/gal per week for the first ten weeks, but once tanks fill, gasoline faces $0.30/gal per week of upward pressure. A short-term diesel cut buys a broader price spike.
Can the ban actually lower fuel prices?
U.S. retail diesel has hit a record $6.53 per gallon and still sits near $6.45 — up roughly 75% year-on-year, per AAA data.
Goldman calculates that while storage tanks still have room, the ban would push U.S. diesel down by about $0.25/gal per week.
But this "discount window" lasts only nine to ten weeks — Goldman estimates tanks will be full by then, and the dynamics reverse.
In plain terms = the ban is like filling a bathtub: prices fall while the tub has room, but once it overflows, the mess is worse than before.
Why would gasoline rise after tanks fill?
Diesel, gasoline, and jet fuel are tightly linked in the refining process — refiners have limited ability to shift the output mix.
This means → once diesel inventories hit tank ceilings, refiners are forced to cut run rates, squeezing gasoline and jet-fuel supply in lockstep.
Goldman estimates that after tanks fill, every additional week of the ban puts roughly $0.30/gal of upward pressure on U.S. retail gasoline.
Goldman adds that refiners will start cutting output before tanks are truly full — so gasoline price pressure arrives earlier than the headline timeline suggests.
How hard does this hit Europe and Asia?
Europe and Latin America are the main destinations for U.S. diesel exports. Each week the ban persists, European wholesale diesel prices rise about 2%.
Europe's strategic petroleum reserves include diesel stocks that could offset roughly half of that price increase.
This means → Latin America and Europe would pivot to compete for diesel from India and other suppliers, spreading the supply shock rapidly into Asia.
After the ban lifts, do prices snap back to normal?
Once lifted, U.S. diesel would re-link to global markets and face upward pressure; overseas prices would ease somewhat.
But Goldman stresses: even post-ban, global refined-product prices would remain higher than in a "never-banned" scenario.
This reflects the temporary drop in U.S. refining output during the ban, which leaves cumulative global inventories below the no-ban baseline — a gap that cannot close quickly.
What trade does Goldman recommend to hedge this?
Goldman classifies a U.S. diesel export restriction as a "very likely scenario."
The bank reiterates its hedge: go long European gasoline to offset geopolitical risk.
Reason one: high diesel prices have already pushed global refiners to shift output from gasoline to diesel; a U.S. ban driving overseas diesel even higher would intensify that shift, tightening gasoline supply further.
Reason two: Europe's strategic gasoline reserves are only one-quarter the size of its diesel reserves — far less policy buffer.
