Did our AI summary help? Let us know.
The hedge ratio is the proportion of an exposure that should be hedged to minimize risk. Delta hedging in options uses the option. For futures, the hedge ratio equals the number of futures contracts needed per unit of spot exposure. Cross hedging occurs when the hedging instrument differs from the asset being hedged (e.g., jet fuel hedged with crude oil futures).

The Hedge Ratio: How Much to Hedge?
The hedge ratio determines how much of your exposure to hedge — a ratio of 1.0 means a perfect hedge, while 0.78 means hedging 78% is optimal. Airlines spend $billions hedging jet fuel using crude oil futures (cross-hedging with 0.88 correlation). Southwest Airlines' fuel hedging saved $3.5B over a decade. The optimal hedge ratio = correlation × (σ_spot/σ_futures) minimizes variance. Delta hedging in options uses the option's delta as the hedge ratio.

Optimal Hedge Ratio Formula
h* = ρ × (σ_spot / σ_futures). Minimizes variance of the hedged position.
Delta Hedging in Options
Options traders use delta as the hedge ratio — hold delta units of underlying per option sold.
Hedge Ratio for Futures
Futures hedge ratio = contracts needed per unit of spot. Perfect correlation + equal vol → ratio 1.0.
Cross Hedging
When hedging instrument differs from exposure (jet fuel vs crude), basis risk remains. Optimal ratio still minimizes variance.
Hedge Effectiveness
Effectiveness = ρ² × 100%. Correlation 0.9 → 81% variance reduction.
When to Use Basic vs Optimal
Basic: when you know your hedge position and want the ratio. Optimal: when you have volatility and correlation data to minimize risk.
Real-World Applications
Commodity producers, airlines, multinationals, and portfolio managers all use hedge ratios for risk management.
Common Mistakes
Using outdated correlations, ignoring transaction costs, over-hedging for tax purposes, and mismatching hedging periods.
