QUICK ANSWER
Diesel fuel hedging locks in or caps the price a fuel-intensive business pays for diesel, protecting budgets and margins from price spikes. Because diesel itself has limited futures liquidity, most programs hedge with ULSD (heating oil) futures and swaps or crude proxies, accepting some basis risk in exchange for liquidity.
For a trucking fleet, railroad, or marine or construction operator, fuel is often the largest and most volatile cost line. Diesel hedging converts that volatility into a known or capped number, so a bad quarter for fuel prices does not become a bad quarter for the business.
What is diesel fuel hedging?
Diesel hedging uses financial instruments to offset the price risk of physical diesel purchases. When diesel prices rise, the hedge gains roughly what the physical fuel costs extra, stabilizing the all-in price. The company keeps buying fuel the same way it always has; the hedge simply neutralizes the price swing.
Who should hedge diesel?
Any business where diesel is a large, uncontrollable share of costs: trucking and logistics, rail, marine shipping, construction, agriculture, and large fleet operators. The more fuel moves your margin, the more a hedge is worth.
How do you hedge diesel?
The core tools mirror any commodity hedge: swaps fix the price outright, calls or caps set a ceiling while preserving downside, and collars bound a range at low cost. The mechanics are the same ones covered in our guide to hedging strategies — applied to fuel.
The basis problem: ULSD and crude proxies
Diesel has limited liquid futures of its own, so most hedges use ULSD (ultra-low-sulfur / heating oil) futures or, more loosely, crude oil. That introduces basis risk — the gap between the hedging instrument and the price you actually pay at the rack or pump. A well-designed program measures and manages that basis rather than ignoring it.
How much should you hedge?
Few companies hedge 100%. A layered or laddered approach — hedging a declining percentage of forecast volume further out — balances protection against the risk of over-hedging a volume you might not burn. The right ratio follows from your budget sensitivity and risk appetite, ideally set in a commodity hedging policy.

Frequently Asked Questions
Why hedge diesel with heating oil (ULSD) futures?
Diesel and ULSD are closely related refined products, and ULSD futures are far more liquid, so they serve as an effective proxy — with some basis risk.
What is basis risk in fuel hedging?
The difference between the hedging instrument's price and the price you actually pay for physical diesel at your location.
Should we hedge all of our diesel?
Rarely. A layered approach that hedges part of forecast volume avoids over-committing to fuel you may not use.
