Hedging with commodity futures helps producers and buyers manage changes in the prices they receive or pay. Farmers, miners, airlines and food companies use them to protect themselves from price swings they can’t control. Understanding hedging with commodity futures also helps you read market data, because commercial positions can reflect physical-business exposure rather than a simple forecast of price direction. This guide explains the two basic hedges, walks through worked examples with numbers, and covers the risks that remain even when a hedge is done well.
What hedging means
Hedging means taking a futures position that offsets the price risk you already face in your business. In other words, if a price move would hurt your business, the futures position is designed to gain from that same move. The hedger is not trying to predict prices. The hedger is trying to make the price matter less.
The CFTC’s Futures Market Basics describes the typical users of futures markets as commercial and institutional producers and consumers of commodities, alongside speculators. A commercial classification can indicate a business that handles the commodity, but does not establish the purpose of every position.
Two basic types of hedge
- Short hedge (selling hedge). Used by producers such as farmers, miners and oil drillers who own or will own a commodity and fear prices will fall before they sell. They sell futures.
- Long hedge (buying hedge). Used by consumers such as airlines, food makers and refiners who will need a commodity and fear prices will rise before they buy. They buy futures.
The rule of thumb: take the futures position that matches what you will eventually do in the physical market. If you will sell the commodity later, sell futures now. If you will buy it later, buy futures now.
A short hedge example with numbers
The following prices and harvest quantity are hypothetical and exclude fees, basis changes and delivery costs. Imagine a corn farmer in spring. She expects to harvest 50,000 bushels in autumn, and she’s worried prices will fall by then. Suppose the December futures price is $5.00 a bushel. CME’s corn contract specifications set a size of 5,000 bushels, so she sells 10 contracts to cover the crop.
- If prices fall to $4.00 by harvest, she sells her physical corn for roughly $4.00 and loses $1.00 a bushel against her spring expectation. However, she buys back her futures at about $4.00, gaining $1.00 a bushel on the short position. Net result: close to $5.00 a bushel.
- If prices rise to $6.00, she sells her corn for roughly $6.00, but her futures position loses $1.00 a bushel when she buys it back. Net result: again close to $5.00.
Either way, she has largely locked in a price near $5.00. She gives up the chance of a windfall in exchange for protection against a bad year, and that trade-off is the whole point. Her lender, her landlord and her seed supplier all benefit from knowing roughly what her revenue will be.
A long hedge example with numbers
Now consider an airline that will need jet fuel over the next year. Rising fuel costs would squeeze its profits, and it cannot pass every increase on to passengers. To protect against that, it buys energy futures today at a price it can live with.
- If fuel prices rise, the airline pays more at the pump, but its long futures position gains and helps cover the higher cost.
- If fuel prices fall, the futures lose money, but the airline pays less for fuel, so the two roughly cancel out.
The airline has swapped an uncertain fuel bill for a more predictable one. It may look like a poor decision in hindsight if prices fall, but the decision was made to protect the budget, not to beat the market.
How a hedge is put on, step by step
- Measure the exposure. How many units of the commodity will you sell or buy, and when? A hedge should be sized to the real exposure, not larger.
- Pick the contract. Choose the futures contract whose delivery month is at or just after the date you expect to sell or buy in the physical market, and whose specification is closest to your product.
- Calculate the number of contracts. Divide your exposure by the contract size. Round down if you want to avoid over-hedging.
- Place the trade through a registered broker and confirm and fund the applicable margin under both exchange and broker terms.
- Maintain the position. Meet margin calls if prices move against the futures leg, and record the hedge against the physical transaction it protects.
- Lift the hedge. When you make the physical sale or purchase, close the futures position by taking the opposite trade. Delivery or offset depends on the business plan, contract and broker terms; arrange that process before trading.
Why hedges are never perfect
In practice, hedging with commodity futures reduces risk but rarely removes it entirely.
- Basis risk. The local cash price a farmer receives won’t move exactly in line with the futures price. That gap, called the basis, can change. If the basis weakens between spring and harvest, the farmer’s locked-in price ends up a little below the $5.00 in the example.
- Quantity mismatch. Futures come in fixed sizes. Moreover, a harvest may turn out bigger or smaller than planned. A farmer who hedged 50,000 bushels and harvests 40,000 after a drought is now partly a speculator on the extra 10,000.
- Cross-hedging. Sometimes no futures contract exists for the exact product. For example, an airline might hedge jet fuel with a related energy contract that doesn’t track it perfectly.
- Margin calls. Even a well-designed hedge can require cash. If prices move against the futures side, the hedger must meet margin calls before the physical sale offsets them. This cash-flow strain can force a business to reduce or close a hedge even when the physical exposure remains.
- Timing mismatch. If the physical sale slips to a later month than the futures contract, the hedger must roll the position, which adds cost and basis exposure.
Hedgers vs speculators
Hedgers want to shed price risk. Speculators, by contrast, willingly take it on in pursuit of profit. Each needs the other: speculators provide the liquidity that lets hedgers trade efficiently, while hedgers provide a steady flow of business.
This split shows up in public data. The CFTC’s weekly Commitments of Traders report breaks positions into groups, including producers and merchants. Reading it with hedging in mind helps explain why producers often hold large short positions without that being a bearish bet.
Common mistakes new hedgers make
- Hedging more than the exposure. Anything beyond the physical position is speculation, whatever it is called.
- Judging the hedge by the futures leg alone. A hedge that “lost” money on futures while the physical side gained has done exactly what it was supposed to do.
- Lifting the hedge early. Closing a losing futures position because it hurts, while the physical exposure remains, converts a hedge into an unprotected bet.
- Ignoring basis history. Checking how the local basis has behaved in past years at the time you plan to sell helps set realistic expectations.
- Underestimating cash needs. Set aside funds for margin calls before the hedge goes on, not after.
Can individual investors hedge?
Some can. For example, an investor holding mining stocks might use futures to reduce exposure to a falling metal price. However, futures are leveraged, and the CFTC describes speculating in them as rarely suitable for retail investors. CME Group also warns that with futures you can lose more than you deposited. Therefore, talk to a licensed professional before using futures to hedge a portfolio.

Frequently asked questions
Does hedging guarantee a profit?
No. Hedging aims to reduce price uncertainty, not to make money. A hedger often gives up potential gains in exchange for protection.
What is basis risk?
Basis risk is the chance that the local cash price and the futures price move differently, making the hedge less effective than expected.
Why do farmers sell futures?
Selling futures lets them lock in a price for crops they’ll harvest later, protecting them if prices fall before harvest.
Do hedgers actually deliver the commodity through the exchange?
Some businesses use delivery, while others offset futures and transact through their usual physical channels. The decision depends on contract eligibility, logistics and broker arrangements.
Conclusion
Hedging with commodity futures is a tool for reducing uncertainty about a future sale price or purchase cost. A short hedge protects someone who will sell; a long hedge protects someone who will buy. Done well, it stabilises revenue or costs at the price of giving up windfalls, and it still leaves basis, quantity and cash-flow risks to manage. Understanding that trade-off makes you a better reader of commodity markets, because a futures position may be one part of a wider physical-business risk plan.
