Modeling Potential US Diesel Export Restrictions: Goldman Sachs Commodities Strategy

Goldman Sachs · September 26, 2026

Goldman Sachs models the impact of a hypothetical US diesel export ban, finding it would initially lower US diesel prices by $0.25/gal per week while spare storage exists. However, once diesel storage fills in 9–10 weeks, forced refinery run cuts would drive US retail gasoline prices up by $0.30/gal per week and raise ex-US refined product prices.

Key Takeaways

  • 1.An initial US diesel export ban would place downward pressure of ~$0.25/gallon per week on retail US diesel prices while domestic storage space remains available.
  • 2.Once US diesel storage fills (estimated in 9–10 weeks), refiners would be forced to cut runs by ~2.1mb/d, pushing retail gasoline prices up by ~$0.30/gallon per week.
  • 3.A ban would raise European wholesale diesel prices by $3/bbl per week (~2%), though European strategic petroleum reserve (SPR) releases could offset roughly half of this increase.
