Short answer
The cost of a currency hedge has three core components: the forward points, which mainly reflect the interest-rate differential between the two currencies (cost of carry – a cost or a gain, depending on direction), the premium for options, and transaction costs from the bid-offer spread, which usually already includes the bank’s margin. On top comes the internal effort per deal. A big lever lies in volume: less unnecessary hedge volume lowers the volume-driven costs.
What hedging costs are made of
| Cost component | What lies behind it | What it depends on |
|---|---|---|
| Forward points / carry | The forward rate differs from the spot rate mainly by the interest-rate differential between the two currencies; in the market the cross-currency basis comes on top. It is not a fee: depending on direction it is a premium or a discount. | Interest-rate differential, tenor, export or import |
| Option premium | The price for the right, but not the obligation, to exchange at a fixed rate. It is usually paid up front. | Volatility, tenor, strike, structure |
| Spread & margin | The difference between bid and offer; the bank’s margin is usually already included in the quoted rate. | Liquidity of the currency, deal size, bank. Considerably higher for emerging-market currencies than for G10 |
| Internal effort | Execution, confirmation, booking, documentation, hedge accounting where applicable. | Number of deals, not their size |
The overlooked cost driver: more hedging than needed
Many hedging policies set a fixed percentage per currency. That is simple and easy to audit. But it hedges each currency as if it stood alone. If your currencies partly offset each other, you carry less risk at portfolio level than the sum of the individual risks. Additional hedging can lower risk further. What matters is whether this additional protection is needed for your risk target and justifies its cost.
- Less volume: hedge up to the portfolio’s risk target, not up to the ratio for each individual currency.
- Cheaper currencies first: where two currencies have a similar effect, hedge the one with lower carry and a tighter spread.
- Fewer deals: a few targeted hedges instead of many small ones reduce internal effort.
Less unnecessary volume lowers volume-driven transaction costs and, where relevant, option premiums. The carry effect depends on currency, direction and tenor – less volume can also reduce a positive carry. What this looks like in practice is shown by correlation-driven hedging.

Same volume, more impact
In the sample portfolio on our correlation-driven hedging page, EUR 10m of hedging targeted in USD lowers risk from 4.6 to EUR 4.0m. The same 10m spread evenly across all currencies: only to EUR 4.3m.
Same hedging volume, considerably more risk impact. See the example →
