Is now a difficult time for small business owners to manage rising fuel costs?
J.B. Hunt warned of a 5% to 10% earnings headwind for the third quarter as fuel costs surged across the United States. The carrier faces pressure from long-term contracts that fail to offset recent spikes in operating-cost inflation.
Why it matters
The margin erosion stems from a narrowing retail-wholesale fuel spread, which prevents carriers from fully recovering their actual costs via standard surcharges. This disconnect forces operators to absorb higher expenses that long-term, fixed-rate agreements currently do not account for.
Retail diesel prices increased by 31% between July 5 and September 17, while the retail-wholesale fuel spread dropped to just above $1 per gallon. This represents a significant decline from the $1.50 per gallon average observed between April and July 2026.
The players
J.B. Hunt
A major U.S.-based transportation and logistics company that operates a large fleet of trucks and provides intermodal and dedicated contract services.
The details
Large carriers typically mitigate fuel volatility by using surcharges linked to retail prices and negotiating bulk fuel purchases at a slight premium to rack prices. However, the current cycle shows wholesale diesel prices rising more than twice as fast as retail prices. Because contract rates are fixed, the carriers cannot adjust fast enough to compensate for these inflated operating expenses during a period where spot market rates have simultaneously declined by 6%.
Timeline
From 2022 through March 2026, the average fuel spread was $1.25 per gallon.
Between April and July 2026, the fuel spread averaged above $1.50 per gallon.
Retail diesel prices began an increase that saw a 31% rise between July 5, 2026, and September 17, 2026.
Since early July 2026, the fuel spread has averaged just above $1 per gallon.
Spot market rates decreased by about 6% during the three-month period preceding September 20, 2026.
Market Landscape
The current margin compression marks a departure from the historical spread of $1.25 per gallon maintained between 2022 and early 2026. This trend suggests that traditional fuel surcharge mechanisms are becoming less effective as wholesale cost inputs decouple from retail price benchmarks.
Operators reliant on long-term logistics contracts should audit their fuel surcharge agreements to ensure they account for wholesale price volatility. Failing to adjust these clauses can lead to significant margin erosion when wholesale inputs rise faster than retail benchmarks.
The takeaway
The divergence between wholesale and retail diesel prices is creating an unsustainable squeeze for carriers on fixed-rate contracts. Management should monitor the retail-wholesale spread as a key leading indicator for operating margin health in the coming quarter.
