Exchange rate risk is the possibility that currency movements change cash flows, asset values, liabilities, earnings, or investment returns.
Exchange rate risk, also called currency risk or foreign-exchange risk, is the possibility that a change in one currency’s value relative to another changes cash flows, asset values, liabilities, reported earnings, or investment returns.
The risk exists whenever the currency of an economic exposure differs from the currency in which the result is measured. It can affect a foreign invoice, bond payment, overseas subsidiary, imported input, investment portfolio, or unhedged borrowing.
| Exposure | What changes | Typical example |
|---|---|---|
| Transaction exposure | Contracted or forecast foreign-currency cash flow | Export receivable, import payable, foreign-currency loan payment |
| Translation exposure | Reporting-currency value of foreign financial statements | Consolidating a euro subsidiary into U.S. dollar accounts |
| Economic exposure | Long-run competitiveness and future operating cash flows | Exchange rates alter pricing, demand, sourcing, and margins |
A single company can have all three. An exporter may have a current foreign receivable, a foreign subsidiary to translate, and longer-term competitive exposure to currency-driven price changes.
| Position | Adverse currency move, measured in home currency |
|---|---|
| Foreign-currency receivable or asset | Foreign currency weakens |
| Foreign-currency payable or liability | Foreign currency strengthens |
| Forecast foreign revenue | Revenue currency weakens before conversion |
| Forecast foreign cost | Cost currency strengthens before payment |
| Short foreign-currency position | Foreign currency strengthens |
| Long foreign-currency position | Foreign currency weakens |
The quote convention matters. A rise in CAD per USD means the U.S. dollar has strengthened against the Canadian dollar, while a rise in USD per CAD means the Canadian dollar has strengthened.
Suppose a Canadian investor earns 8% on a U.S. stock measured in U.S. dollars. During the holding period, the U.S. dollar falls 5% against the Canadian dollar.
The exact Canadian-dollar return is:
Home-currency return = (1 + local return) x (1 + currency return) - 1
= 1.08 x 0.95 - 1 = 2.6%
The stock gained 8% locally, but the weaker U.S. dollar reduced the investor’s Canadian-dollar return to approximately 2.6%. Simply subtracting 5% from 8% gives 3%, which misses the compounding interaction.
If the U.S. dollar had fallen by more than the stock gained, the investor could have had a home-currency loss despite a positive local-market return.
A U.S. importer agrees to pay EUR100,000 in 90 days. At USD1.08 per euro, the expected dollar cost is USD108,000. If the euro strengthens to USD1.14 before payment, the invoice costs USD114,000, an additional USD6,000 before fees.
The company might lock a forward rate, buy an option, match the payable with euro revenue, or leave the position open. Each choice changes the risk profile and cost; none makes the underlying business decision automatically profitable.
List foreign-currency assets, liabilities, commitments, and forecast cash flows by currency and date. Netting is appropriate only when timing, legal entity, accessibility, and settlement terms make the offset usable.
Apply a defined appreciation or depreciation to the net exposure. A 10% scenario is illustrative and should not be described as a prediction.
Statistical models estimate potential changes over a horizon at a stated confidence level. Results depend on historical data, volatility, correlations, and model assumptions.
Test devaluation, illiquidity, convertibility limits, broken pegs, widening forward points, and counterparty failure. Stress scenarios can reveal risks that ordinary volatility models omit.
| Approach | Main use | Key limitation |
|---|---|---|
| Forward contract | Lock a future conversion rate | Creates an obligation and counterparty exposure |
| Currency option | Limit adverse moves while retaining some upside | Premium cost and option complexity |
| Currency swap | Exchange longer-term currency cash flows | Credit, collateral, valuation, and documentation risk |
| Natural hedge | Match revenue, costs, assets, or debt in one currency | Amounts and timing rarely match perfectly |
| Diversification | Spread exposure across currencies and economies | Correlations can rise during stress |
Hedging the accounting exposure may not hedge the economic exposure. A forward can cover a known invoice but not fully protect demand, pricing power, or future sourcing costs.
