EIA Raises 2026 Diesel Forecast as Distillate Inventories Tighten
EIA's September outlook raises its 2026 retail diesel forecast to $5.07 per gallon and expects U.S. distillate inventories to fall below 100 million barrels in September, creating a higher-cost planning environment for fleets and fuel-intensive businesses.
What the September 9 outlook forecasts
Source publication date: September 9, 2026. The U.S. Energy Information Administration raised its forecast for the 2026 average retail diesel price to $5.07 per gallon from $4.85, a 4.4% increase from the prior forecast. Its 2027 forecast increased to $4.40 from $4.07. The September forecast was completed using inputs finalized on September 3, so later market events are not specifically incorporated.

Inventory tightness supports the higher-cost outlook
EIA expects U.S. distillate fuel-oil inventories to drop below 100 million barrels in September and remain below the 2021–2025 five-year low through much of 2027. It said tight global distillate conditions have raised domestic prices and encouraged exports. The agency forecasts Brent crude near $90 per barrel in the second half of 2026 before averaging $74 in 2027 as production rises and inventories rebuild.
Why fuel prices matter to a financing request
For trucking, delivery, agriculture, construction, field services, and other fuel-intensive borrowers, higher diesel costs can increase the working-capital cycle and compress coverage before customer pricing catches up. An equipment purchase may improve fuel efficiency, utilization, maintenance, or capacity, but underwriting should separate measurable savings from optimistic assumptions and include delivery, installation, training, downtime, and ramp-up costs.
Practical borrower takeaway
Update the base case with current invoices, gallons consumed, mileage or machine hours, fuel surcharges, customer repricing terms, and payment timing. Model an elevated-price case and a slower-recovery case, then show how liquidity, margin, and debt-service coverage respond. If new equipment is part of the solution, document expected fuel and maintenance savings with vendor specifications and operating history while recognizing that final credit terms remain lender-specific.
Fleet and fuel-intensive borrowers should refresh fuel assumptions, quantify route and utilization sensitivity, and preserve working-capital and debt-service capacity if diesel prices remain elevated longer than expected.
