What it means
In business, you often face price risks that you cannot insure directly. For example, your factory might rely on a specialised chemical that has no futures market.
To protect your business from price spikes, you look for a related product that does have a traded market, such as crude oil or natural gas, which tends to move in the same direction. By taking a position in this substitute market, you create a shield against adverse price movements.
This matters because unprotected price volatility can destroy your profit margins overnight. Without a hedging strategy, purchasing costs or selling prices are left entirely at the mercy of market whims.
A cross hedge offers a practical way to lock in predictable costs and stabilise cash flow, even when dealing with niche commodities or localized currencies. In practice, managing a cross hedge requires careful monitoring because the correlation between your two assets is never perfect.
If jet fuel prices rise, heating oil prices usually follow, but the exact ratio shifts depending on supply and demand. Finance teams must calculate the optimal hedge ratio to ensure they neither over-insure nor leave the business exposed to unexpected basis risk.
In practice
Real-world examples.
Example
An airline needs jet fuel, which has no direct futures market. To protect against rising fuel bills, the finance team buys heating oil futures instead, knowing the two prices generally move together.
Example
A UK manufacturer selling goods to customers in Poland invoices in Polish Zloty. Since Zloty futures are illiquid, the firm hedges its currency risk using more widely traded Euros.
Example
A coffee shop chain cannot easily hedge the cost of organic vanilla syrup directly, so it buys sugar futures to offset some of the general volatility in sweetening ingredient costs.
Think of it
“Imagine you cannot buy an exact spare tyre for your vintage car, so you buy one for a slightly different model from the same manufacturer. It is not a 100 percent match, but it will keep you moving safely if you get a flat.
Formula
Calculation
Hedge Ratio = Correlation Coefficient between Asset A and Asset B multiplied by (Volatility of Asset A divided by Volatility of Asset B).
Example: If Jet Fuel has a volatility of 0.25, Heating Oil has a volatility of 0.20, and their correlation is 0.80, the ratio is 0.80 x (0.25 / 0.20) = 1.0. For every 1,000 gallons of fuel needed, you buy 1,000 gallons of heating oil futures.Case study
Seen in the real world.
North Sea Plastics, a mid-sized packaging manufacturer based in Aberdeen, relied heavily on a specialized polymer derived from butane. When supply chain disruptions threatened to spike butane prices, the firm found that direct hedging contracts were unavailable or prohibitively expensive. The finance manager decided to set up a cross hedge using Brent Crude oil futures, as historical data showed a strong price link between crude oil and polymer feedstocks.
The company purchased Brent Crude futures contracts equivalent to its expected quarterly butane consumption. Two months later, oil prices surged by 20 percent, driving up the cost of raw polymer by 18 percent. Fortunately, the value of North Sea Plastics' futures contracts rose in tandem, generating a trading profit that offset the higher raw material bills. While basis risk meant the payout did not cover the cost increase to the exact penny, the cross hedge successfully protected the company operating margin, saving them over 45,000 pounds in unexpected expenses during a volatile trading quarter.
Watch out
Common mistakes.
- Assuming the correlated asset will always move in lockstep with your exposure.
- Failing to account for basis risk, which is the price gap between the two different assets.
- Using a completely unrelated market just because it is easy to trade.
Questions
People also ask.
Why not just use a direct hedge?
A direct hedge is always preferred, but direct financial contracts do not exist for every niche commodity, raw material, or local currency.
What is basis risk?
Basis risk is the danger that the price of your asset and the price of your hedging asset stop moving together, leaving you exposed to losses.
How often should I review a cross hedge?
You should review it regularly, at least monthly, because the statistical relationship between two different assets changes over time.
