Van freight spot rates reached $2.52 per mile in March 2026, the seventh consecutive monthly gain and the highest level in over two years, according to DAT Freight & Analytics' April 14 press release. The figure is a truckload freight metric, not a last-mile delivery rate. But the mechanism behind it tells last-mile operators something concrete about how different parts of the logistics industry are pricing the same diesel spike — and who is absorbing the difference.
How the Freight Market Is Recovering Fuel Costs
The March rate increase wasn't driven by demand. DAT Freight & Analytics was explicit: the surge was primarily the result of elevated fuel surcharges. The average van fuel surcharge hit $0.61 per mile in March, up from roughly $0.40 per mile throughout most of 2025 — a 52 percent increase in a single quarter, per the DAT April 14 release.
Fuel surcharges in truckload freight are indexed to the EIA's national diesel retail average and adjust automatically, typically on a weekly or monthly basis, as diesel prices move. When diesel rises, shippers absorb the incremental fuel cost through higher surcharges; carriers protect their linehaul margin. DAT's April release noted that even with elevated surcharges, linehaul margins face compression because surcharge tables lag the sharpest price moves — but the mechanism transfers the majority of diesel cost volatility to the shipper side of the transaction rather than letting it accumulate on the carrier's income statement.
At the current EIA national diesel average of $5.643 per gallon, reported for the week of April 6 per EIA retail fuel price data, the van fuel surcharge is running $0.21 per mile above its 2025 baseline. On a vehicle covering 150 miles per day — a reasonable daily range for a delivery van — that's $31.50 in daily fuel cost recovery, or approximately $7,875 per year per vehicle, now flowing from shippers to carriers rather than compressing carrier margins.
The Contrast for Last-Mile Operators
Last-mile rate structures generally don't work this way.
Amazon Delivery Service Partners have fuel costs addressed through program-level arrangements — the fuel cost sits with the network rather than being indexed against operator revenue as prices move. For FedEx Ground Independent Service Providers, rate card terms are negotiated separately from FedEx's shipper-facing fuel surcharge schedule. For USPS contract carriers and independent parcel operators, fuel exposure depends primarily on the contract structure at time of signature. The common condition across most last-mile arrangements is that rate cards don't automatically adjust when diesel moves.
The arithmetic of what that means since January 2026 is specific. The EIA diesel average for the week of January 5, 2026 was $3.477 per gallon. By April 6, that figure had reached $5.643 per gallon — an increase of $2.166 per gallon, or 62 percent, per EIA retail diesel data. For a delivery van running 150 miles per day at 10 miles per gallon, the daily fuel cost has moved from $52.16 to $84.65 — a difference of $32.49 per vehicle per day.
| Metric | January 5, 2026 | April 6, 2026 | Change | |---|---|---|---| | EIA national diesel | $3.477/gal | $5.643/gal | +$2.166/gal (+62%) | | Daily fuel cost (15 gal/day) | $52.16/van | $84.65/van | +$32.49/van | | Annual fuel cost (250 days) | $13,039/van | $21,163/van | +$8,124/van | | 25-van fleet, annual | $325,969 | $529,063 | +$203,094 |
The truckload market's surcharge mechanism would recover approximately $7,875 of that $8,124 per-van annual increase from shippers. For last-mile operators running fixed rate cards with no fuel adjustment provision, that full amount compresses operating margin — with no equivalent pass-through.
The Spot Market for Operators with Flexible Capacity
The DAT data is also actionable for operators with van capacity that isn't fully committed to fixed delivery routes. Operators running Ford Transits, Mercedes-Benz Sprinters, cargo vans, or similar units who have capacity gaps — weekend availability, off-peak scheduling windows, or seasonal route gaps — can access the spot truckload market through load boards including DAT's own network.
At current rates, a qualified van operator picking up a regional or short-haul load is looking at approximately $2.47 to $2.52 per mile spot, plus $0.61 per mile in fuel surcharge recovery. The effective combined rate of $3.08 to $3.13 per mile is, per Overdrive Online's April 15 coverage of the DAT data, more than 50 cents per mile above the 2024 full-year van average on an all-in basis.
The spot window will compress when diesel stabilizes and capacity reenters the market. Freight markets have historically tightened and loosened in parallel with fuel cycles. But operators who can model the comparison — what their current effective per-stop rate works out to on a per-mile basis versus what the open truckload market currently pays — have cleaner data for evaluating the next contract cycle, capacity allocation decisions, or rate renegotiation conversations.
The core question the DAT data surfaces for any last-mile operator: does your current rate structure include any mechanism to adjust when diesel moves, and if not, who is carrying the fuel cost exposure in your operation?
