FX Forward Hedging Estimator
Estimate the cost or benefit of hedging a foreign-currency exposure back into GBP with a forward contract, using covered interest rate parity, versus staying unhedged.
Data verified · July 2026
Why is the forward rate different from the spot rate?
The forward rate reflects the interest rate differential between GBP and the foreign currency over the contract term — this is covered interest rate parity, not a forecast of where the spot rate will actually move.

Everything about FX Forward Hedging Estimator
📋Overview+
Forward points are derived from the GBP vs foreign money-market interest rate differential over the contract term: a higher GBP rate than the foreign rate produces a forward premium (forward rate above spot); a lower GBP rate produces a forward discount. This is a planning tool for sizing hedge decisions — actual bank forward quotes include a dealer spread and should be used for execution.
💡 Best practices
- A forward contract locks in a rate now, removing FX risk — but if the currency moves in your favour, you give up the upside too.
- This is a planning estimate; get a dealable quote from your bank or FX broker before executing a real hedge.
- Compare the hedged GBP value against your expected future spot scenario to judge whether hedging is worthwhile for your risk appetite.
🔢 Concrete example
€100,000 exposure, spot rate 0.85, GBP rate 5%, foreign rate 3%, 3-month forward: forward rate around 0.8543, valuing the exposure at roughly £85,430 versus £85,000 at spot.

Should I always hedge my FX exposure?+
Not necessarily — hedging removes uncertainty but also removes upside if the currency moves in your favour. Compare the hedged value against your expected future spot scenario to decide.
