US diesel tops $6 a gallon as Gulf supply lags; EIA sees record 13.8M b/d crude in 2026
Diesel is over $6 a gallon, and for jobbers the rack got there first. When retail crosses that line on a supply squeeze, allocation is already tight and the unbranded gallons are the ones that dry up.
The diesel squeeze
About 19 outlets reported US diesel topping $6, tied to supply pressure from the Iran conflict. The pump number matters less to a marketer than what it says about the rack. When distillate gets scarce, terminals meter it out, branded contracts get filled first, and spot buyers pay up or wait. Haulers eat it either way, because freight surcharges lag the rack by days.
Record crude, tight product
EIA's latest STEO forecasts US crude production averaging 13.8 million b/d in 2026, past the 13.7 million b/d record set in 2025. More crude at the wellhead does not automatically put more diesel at the rack. Crude and refined product are separate markets, and the pinch right now is in distillate, not in barrels coming out of the ground.
The Gulf gap
IEA warned the 2026 oil supply gap could widen because normal Gulf flows are returning slower than expected. For US wholesale, weigh that against EIA's record forecast: domestic barrels are climbing while global supply lags. If Gulf flows stay delayed, crack spreads could hold firm and rack diesel could stay bid into next year.
Overseas, briefly
Two items don't touch your rack. ICRIER urged India to ease its E15 ethanol mandate over feedstock supply worries, which is India's blending fight, not a US RIN or RVO question. WinGD will supply methanol and ethanol dual-fuel engines for Polaris Shipping's Newcastlemax fleet, a marine demand signal years out. Neither changes what you pay at the terminal this week.
What to watch
Whether diesel holds above $6 or eases as the supply scare fades. Whether EIA's 13.8 million b/d crude forecast turns into more distillate or just more light crude that US refiners can't fully run into diesel. And whether the Gulf flows IEA flagged come back on schedule, because a longer delay could keep the rack bid and allocation tight through the winter.
