The Fuel-Surcharge Playbook: Which Logistics Operators Win as Diesel's 2022 Analog Crushes Demand

On Thursday, September 10, the U.S. national average price of diesel crossed $6 a gallon for the first time on record, blowing past the $5.82 peak that set off the last fuel crisis in June 2022. For anyone moving freight — and for any investor in a trucking stock — the real question is not the pump price but what brings it back down. This time the answer is different, and it splits the industry into operators that get richer and operators that get absorbed.

The establishment reading of any price spike is that supply catches up and prices normalize. That is the wrong frame here. U.S. refineries are already running at 98% of capacity, the highest since 2018, with the Midwest pushed past nameplate. Distillate production actually fell 2.4% year over year even as refiners processed more crude, because they are limited by configuration, not throughput. There is essentially no spare domestic capacity to "run harder," and East Coast distillate inventories have fallen to a record low 19.3 million barrels, a third below a year ago.

That is why the rebalancing is coming from the demand side. In the latest EIA week, product supplied of distillate — the on-the-ground measure of diesel and heating-oil consumption — fell roughly 10% year over year, and the four-week average ran about 6% below the prior year. Carriers are taking lighter loads, cutting mileage, and shippers are paying more to move less. That is the volume-pullback mechanism, and it is the slow, grinding kind.

The 2022 analog is the playbook. Diesel hit $5.82 in June 2022, and it did not come home quickly: prices stayed structurally elevated, only falling below pre-crisis levels by mid-2023, with full normalization stretching into 2024 — roughly a two-and-a-half-year adjustment. The pattern is that once diesel reaches crisis heights, the market rebalances through rationing demand rather than through fast supply additions. Nothing about this year's refining ceiling or inventory hole suggests a faster path.

The screen that separates the survivors

Fuel is not a small line. For a truckload carrier, fuel is roughly a quarter to a third of revenue. Three variables decide whether that exposure is managed or fatal.

First, fuel cost as a share of revenue is the exposure meter. A diversified operator whose revenue leans on intermodal rail (J.B. Hunt), or an LTL carrier whose revenue is dense enough to dilute fuel, sits at a fraction of the exposure of a pure long-haul truckload book.

Second, surcharge indexation has to meet the realized cost. The industry's surcharges are indexed to the DOE's weekly national-average diesel price, reimbursing carriers in cents per mile above a baseline. When a carrier's actual fleet burn and lane-level pump prices track the national index, the surcharge covers the fuel cost — and can exceed it. When a carrier runs rural lanes where diesel prices run above the national average, or its index lags a fast-moving spike, it eats the gap.

Third, fleet MPG compounds with price. Because the surcharge is paid on a benchmark miles-per-gallon rate, a modern fleet delivering 7 MPG is reimbursed as if it burned fuel at the 6 MPG benchmark. That spread is worth a few cents a mile at $3 diesel and several times more at $6, so efficiency widens into a real profit edge exactly when the shock hits.

Put the three together and the winners are the diversified, contract-driven operators with modern fleets. Old Dominion's per-hundredweight revenue rose 11.3% with fuel surcharges in the mix (4.8% without them); LTL surcharges have run above 40% of line-haul charges. J.B. Hunt's fuel surcharges can run to hundreds of millions per quarter, and its intermodal mix hedges the diesel barrel itself. These operators also collect the benefit of a consolidating market: since January 2024 more than 8,000 carriers have revoked operating authority or shut down, Yellow liquidated, Convoy folded, and small-fleet bankruptcies kept rolling through 2026 — NV Freight (52 trucks, Chapter 11 with up to $10 million in liabilities) and NAS Logistics (27 trucks) among the latest.

The strain concentrates exactly where the screen points: thin-margin pure truckload and small carriers. Werner, a pure truckload book, printed a 1.8% GAAP operating margin in Q2. The small carriers — fuel a quarter to a third of revenue, older trucks near the low end of the MPG range, no contract surcharge buffer, and lanes whose diesel costs overshoot the national index — are the ones forced into bankruptcy and consolidation. Their truck count is the supply bleed that tightens the freight market for the survivors.

The two ways the thesis breaks

The first bear case is that diesel mean-reverts quickly through a Hormuz reopening. That one has already been tested and, so far, failed. The Strait reopened in July and crude prices fell, yet U.S. diesel never normalized and surged to fresh all-time records in September as U.S.–Iran fighting resumed. The residual real risk is a durable, complete Hormuz fix plus Saudi spare capacity coming back online — the one event that would break the whole loop.

The second is subtler and the one insiders are actually watching. Fuel surcharges have become, in the words of one freight consultancy, "a profit center rather than a cost recovery tool," and shippers are fighting back; intermodal is already taking share from long-haul truckload. If over-indexation pushes shippers to renegotiate or divert volume permanently, that is the mechanism pulling the floor out from under the "winners" this shock creates.

The through-line for an investor: the shock is being transmitted as margin protection for the efficient and consolidation for the inefficient. Diesel demand was already pulling back — that is the demand destruction doing the rebalancing work, slow as it is. The operator whose model converts high diesel into pricing power while smaller rivals fold is the structural winner, and the warning sign to respect is not the likely path of supply but the shipper revolt building against the surcharge itself.
