How producers, consumers, and investors use futures to hedge price risk — the mechanics of a short hedge and a long hedge, basis risk, and how to size a hedge to match your underlying exposure.
Key Takeaways
- A hedge locks in a price today to neutralize future price uncertainty.
- A short hedge protects an existing asset from falling prices.
- A long hedge protects a future purchase from rising prices.
- Basis risk is the imperfect correlation between the hedge and the exposure.
- The hedge ratio sizes the futures position to match the underlying quantity.
Why Hedge with Futures?
Hedging is the original purpose of the futures market. A business with exposure to a commodity or financial price uses futures to lock in that price today, removing the uncertainty of where it will be when the actual transaction occurs. The hedge does not aim to profit — it aims to make the outcome predictable.
The Short Hedge
A short hedge is used by someone who owns or will produce an asset and wants protection against a price decline. A farmer expecting to harvest 50,000 bushels of corn sells 10 corn futures contracts (5,000 bushels each). If corn falls before harvest, the futures profit offsets the lower cash sale price. If corn rises, the futures loss offsets the higher cash price — either way, the net is locked near the original futures price.
The Long Hedge
A long hedge is used by someone who will need to buy an asset and wants protection against a price rise. An airline needing jet fuel next quarter buys heating oil or crude futures. If fuel prices rise, the futures profit offsets the higher fuel cost. The airline has locked in its effective fuel price regardless of where the market goes.
Basis Risk
Basis is the difference between the local cash price and the futures price: Basis = Cash − Futures. A perfect hedge requires basis to be constant, but it rarely is — the local cash market and the exchange-traded futures do not move in perfect lockstep. The residual risk from an imperfect correlation is basis risk. Hedgers monitor basis and may use different contract months or exchanges to minimize it.
Even a well-sized hedge leaves you exposed to the difference between your actual cash price and the futures price at delivery. That gap — the basis — can widen or narrow, creating a partial gain or loss on the hedge.
The Hedge Ratio
The hedge ratio sizes the futures position to match the underlying exposure. The simplest (naive) hedge ratio is 1:1 — one futures contract per unit of exposure. A more precise ratio uses the historical beta/correlation between cash and futures price changes: Hedge Ratio = β × (Cash exposure value ÷ Futures contract value). This minimizes the variance of the combined position.
| Hedge Type | User | Position | Protects Against |
|---|---|---|---|
| Short hedge | Producer / owner | Sell futures | Price decline |
| Long hedge | Consumer / buyer | Buy futures | Price rise |
| Cross hedge | Similar but not identical asset | Use correlated contract | Both (with basis risk) |
Hedging a Stock Portfolio with Index Futures
Investors hedge equity exposure by shorting index futures. To hedge a $1,000,000 portfolio with ES futures (notional ≈ $250,000 each at 5,000), sell roughly 4 contracts — adjusted by the portfolio’s beta. If the market falls, the short-futures profit offsets portfolio losses, letting the investor avoid selling stocks. This is how institutions protect against known event risk without liquidating holdings.
Sizing a Hedge
Size a hedge from the quantity of exposure, not from a risk percentage — the goal is to match the underlying, not to speculate. The TradeRiskMath futures calculator helps you see the dollar risk per contract so you can confirm the hedge size matches your exposure without unintended leverage.
Frequently Asked Questions
What is a futures hedge?
A hedge is a futures position taken to offset the price risk of an existing or planned cash exposure: a short hedge for owners who fear a price drop, a long hedge for buyers who fear a price rise.
What is basis risk?
Basis risk is the gap between your actual cash price and the futures price at delivery. Even a well-sized hedge leaves you exposed to basis movement, which can create a partial gain or loss.
How do I size a hedge?
Size the futures position to mirror the underlying quantity you are protecting, roughly one contract per hedged unit, adjusted for the contract’s quantity and your exposure.
Does a hedge make money?
A hedge is not meant to profit; it is meant to make the outcome certain by offsetting cash-market losses with futures gains (or vice versa). The goal is price certainty, not direction.
Where can I size a hedge?
The TradeRiskMath Futures calculator sizes from your dollar risk and stop. Open it from the Futures hub.
The Bottom Line
Hedging with futures turns unpredictable future prices into a locked-in outcome today. Match the hedge type to your exposure (short for owners, long for buyers), respect basis risk, and size the futures position to mirror the underlying quantity. Done right, a hedge does not make or lose money on direction — it makes the outcome certain.
