US diesel futures post biggest daily gains in four years after Russia bans exports

Russia's ban on diesel exports sent U.S. diesel futures up 11.6% — the biggest one-day jump since March 2022.
Global diesel supply is already tight after refinery attacks, plant closures and OPEC+ cuts; U.S. distillate stocks fell about 5 million barrels to ~103.6 million (≈7% below the 5‑year average).
The move could push wholesale/pump prices higher (analysts expect >$0.40/gal increases) while boosting refiners' margins — a fresh inflation concern.
