CFA Level 3 currency hedging decision framework
Start a currency hedge with the investor’s base currency, foreign-currency exposure and hedge objective. Select the direction and size, consider costs and instrument risks, then evaluate the residual exposure in base-currency terms.
The key ideas, at a glance
Exposure
Read the visual, then follow the worked example below. Use the stated case assumptions.
Illustrative worked case
EUR million
- Hedged
- 1.5 (75%)
- Unhedged
- 0.5 (25%)
The case hedges 75% of a EUR 2m asset by selling EUR forward and buying USD. The remaining EUR 0.5m excludes later asset-value changes.
| Concept | Rule or decision | Common mistake |
|---|---|---|
| Exposure | Translate the foreign asset’s value into its currency exposure and the investor’s base currency. | A currency pair quote must be read in the stated direction. |
| Hedge direction | A long foreign-currency asset can be hedged by selling that currency forward against the base currency. | A reversed position increases exposure instead of offsetting it. |
| Hedge ratio | Hedge notional = exposure × selected hedge ratio under matching units. | Changing asset values can cause overhedging or underhedging between rebalances. |
| Costs and residual risk | Consider forward pricing, roll needs, basis risk, liquidity and counterparty exposure. | A currency hedge does not remove the underlying asset’s investment risk. |
01Exposure
Translate the foreign asset’s value into its currency exposure and the investor’s base currency.
Watch for: A currency pair quote must be read in the stated direction.
02Hedge direction
A long foreign-currency asset can be hedged by selling that currency forward against the base currency.
Watch for: A reversed position increases exposure instead of offsetting it.
03Hedge ratio
Hedge notional = exposure × selected hedge ratio under matching units.
Watch for: Changing asset values can cause overhedging or underhedging between rebalances.
04Costs and residual risk
Consider forward pricing, roll needs, basis risk, liquidity and counterparty exposure.
Watch for: A currency hedge does not remove the underlying asset’s investment risk.

Put the method to work
One worked example, from facts to answer
Given
A USD-based investor holds a EUR 2 million asset and wants to hedge 75% of its euro exposure.
Method
EUR hedge notional = 2,000,000 × 0.75 = 1,500,000. Sell EUR forward and buy USD for the matching date.
Answer and interpretation
EUR 500,000 remains unhedged before asset-value changes. The hedge reduces currency exposure, not the asset’s other risks.
Original independent teaching example. Assumptions are stated above; this is not an official exam question or scoring key.
Apply the framework, step by step
Specify a base-currency exposure, choose hedge direction and size, and interpret what remains unhedged. Use Derivatives and Risk Management for the wider portfolio-exposure framework.
Before you start: Currency quote direction, foreign asset returns, forward obligations and hedge ratios.
METHOD 01
Exposure
Translate the foreign asset’s value into its currency exposure and the investor’s base currency.
Write the investor’s base currency and the asset’s foreign-currency exposure. A quote in USD per EUR converts euro proceeds into dollars by multiplication. The inverse quote requires the corresponding inverse operation. Keep the foreign asset’s investment return separate from its currency translation effect; a positive local return can become a smaller gain or a loss in base-currency terms.
Avoid this mistake: A currency pair quote must be read in the stated direction.
METHOD 02
Hedge direction
A long foreign-currency asset can be hedged by selling that currency forward against the base currency.
For a long foreign-currency asset, selling that foreign currency forward against the base currency offsets a specified currency exposure at the matching maturity. Check the settlement date and the position’s direction before using a contract. A short asset or a future liability can require a different hedge direction. The word hedge does not make a reversed contract economically offsetting.
Avoid this mistake: A reversed position increases exposure instead of offsetting it.
METHOD 03
Hedge ratio
Hedge notional = exposure × selected hedge ratio under matching units.
A simple hedge notional equals exposure times the chosen hedge ratio in the same currency. A partial hedge deliberately leaves some currency exposure. As asset values or expected receipts change, the original notional can become too large or too small, so the policy should address review and rebalancing. A hedge against an uncertain future amount can introduce its own mismatch.
Avoid this mistake: Changing asset values can cause overhedging or underhedging between rebalances.
METHOD 04
Costs and residual risk
Consider forward pricing, roll needs, basis risk, liquidity and counterparty exposure.
Consider forward pricing, roll needs, cash collateral, counterparty exposure and liquidity alongside the currency objective. A hedge can reduce one risk while introducing costs and implementation constraints. It does not remove the local-market risk of the underlying investment. Evaluate base-currency outcomes under the case’s assumptions rather than assuming that a higher hedge ratio is always preferable.
Avoid this mistake: A currency hedge does not remove the underlying asset’s investment risk.
Apply it to a different case
- New facts
- A USD-based investor’s euro asset earns 5% locally, while the USD-per-EUR spot rate falls 2%. Ignore costs and any hedge.
- Working
- USD return = (1 + 0.05) × (1 - 0.02) - 1 = 0.029.
- Conclusion
- The unhedged base-currency return is 2.9%. Simply subtracting 2% from 5% misses the cross-product term.
Original teaching case under the stated assumptions, rather than an official exam question.
Questions about this method
- Which direction hedges a long foreign-currency asset?
- In the simple matching-date setup, sell the foreign currency forward and buy the base currency. Verify the exposure and quote convention; a liability or short exposure can require the opposite direction.
- Does a 100% currency hedge remove all investment risk?
- No. It targets a specified currency exposure. Underlying asset risk, imperfect matching, liquidity, counterparty and implementation risks can remain.
- Why does a hedge ratio need review?
- The asset’s value or expected cash flow can change while the contract notional stays fixed. The intended ratio can drift, producing underhedging or overhedging.
