Fuel Hedging for Fleets 2026: Cap, Swap & Collar Guide

Fuel hedging is a financial risk management practice where a commercial fleet uses derivative contracts (swaps, options, futures) to reduce exposure to diesel price volatility. It is not a fuel-savings program. A hedge does not guarantee the fleet pays less for fuel; it guarantees the fleet knows what it will pay within a defined range. Three main instruments dominate fleet hedging. Swaps: lock in a fixed fuel price for a set future period; the fleet gains when market prices rise above the swap price and loses when prices fall below it. Caps (call options): set a ceiling on the worst-case fuel price the fleet will pay; the fleet participates fully in any price decreases but pays a premium up front for the ceiling protection. Collars: combine a cap (call option) with a floor (put option) to bound the fleet's fuel cost inside a defined range; often structured as zero-cost when the premium from selling the put fully funds the premium of buying the call. Most fleet hedges use ULSD (ultra-low-sulfur / heating oil) futures traded on CME as the reference contract, or the underlying crude oil for looser hedges. The choice of instrument depends on the fleet's volatility tolerance, hedge ratio strategy, fuel surcharge pass-through capacity, and CFO risk preferences.

Almost never. Over-hedging — locking in more volume than the fleet actually burns — converts a hedge from risk management into speculation, because contracted volume that does not get consumed still settles against the reference price. If business slows and actual gallons consumed fall short of hedged volume, the fleet is exposed on the excess without any offsetting physical fuel purchase. Sophisticated hedgers use layered or laddered approaches that hedge a declining percentage of forecast volume as time horizon extends. Published examples: LATAM Airlines hedged 37% of near-quarter fuel consumption through collars, dropping to 27% one quarter out, 12% two quarters out, 7% three quarters out. Agnico Eagle hedged 54% of 2026 diesel exposure at a benchmark benchmark price. The ladder is refreshed monthly — as near quarters expire, outer quarters step up in hedge ratio and a fresh outer-quarter layer is added at low ratio. The layered approach produces smooth, predictable hedging behavior without concentrated exposure to any single price point. Fleets that hedge 100% at a single forward date create their own volatility: they win big or lose big depending on where prices settle. Layered hedges produce moderate results in every scenario, which is usually what CFO-driven risk management values.

Basis risk is the gap between the price of the financial hedge instrument (typically ULSD futures at NY Harbor or Gulf Coast) and the actual price the fleet pays for physical diesel at the rack or pump. Because diesel has limited liquid futures of its own, most fleet hedges use ULSD (ultra-low-sulfur / heating oil) or crude oil as a proxy. The proxy is imperfect. Historic basis between NY Harbor ULSD futures and pump diesel varies by region, season, and market disruption. During Gulf Coast hurricane disruptions, regional pump prices can spike while ULSD futures move less, producing hedge losses that do not fully offset pump price gains. Refinery outages, pipeline shutdowns, and geopolitical events all move basis. A well-designed hedge program monitors basis history for the fleet's specific operating region and adjusts hedge ratios accordingly — a hedge is worth more when basis is stable and worth less when basis is volatile. Physical fixed-price supply contracts direct with the fuel supplier have zero basis risk on contracted volume (though supplier credit risk applies). Financial hedges always carry basis risk. Sophisticated fuel management programs typically combine physical and financial hedges to manage both price risk and basis risk together.

Not entirely, but a well-designed fuel surcharge program is the single most important natural hedge a trucking fleet has, and it should be the first layer of any fuel exposure management strategy. Fuel surcharges pass through fuel-price changes to shippers via a formula indexed to a public reference (typically the US Department of Energy weekly diesel price). Well-negotiated surcharges cover 70-90% of fuel-price movement on committed contract lanes with credit-worthy shippers. Two important gaps remain: negotiated pass-through ratios rarely hit 100% (there is always a portion of price movement the fleet absorbs), and spot-market freight typically lacks the surcharge mechanism entirely (spot rates are all-in and fluctuate independently). Financial hedges cover the residual exposure that surcharges do not. A typical layered approach: 70-80% fuel surcharge pass-through on committed lanes, 10-20% physical fixed-price supply contract, and 20-40% financial collar on the residual near-quarter exposure. Total financial hedge ratio typically under 25% of fleet consumption. Fleets that skip the surcharge layer and rely on financial hedging alone routinely over-commit to the wrong risk and end up with hedge losses that could have been prevented by pricing discipline with shippers.

At minimum, 12 months of accurate per-truck, per-route, per-region diesel consumption data with dollar spend and pump-price basis captured. Without this baseline, the fleet cannot answer any of the three questions a hedge program requires. First, what is the exposure? Total forecast gallons over the hedge horizon determines the notional size of any instrument. Under-estimating leaves exposure unhedged; over-estimating creates the over-hedging risk that turns hedges into speculation. Second, what is the basis? Regional pump-price versus reference contract (NY Harbor ULSD, Gulf Coast ULSD, WTI crude) determines which instrument tracks the fleet's actual costs most closely. Fleets buying primarily at Gulf Coast terminals should not use NY Harbor ULSD hedges without adjusting for consistent basis differential. Third, what is the residual after natural hedges? Fuel surcharge pass-through on committed lanes and physical fixed-price supply contracts already cover a significant portion of exposure. Financial hedging should size only to the residual, not to total consumption. Fleets that enter hedge programs without this data typically overpay for coverage, over-hedge notional volume, and produce hedge P&L that swings widely with each quarter. Structured fuel data capture per unit, per route, per fuel purchase produces the operational baseline every hedge program needs before its first contract is written — and provides the ongoing measurement to prove or disprove the program's effectiveness quarter by quarter.
