Currency Exposure
The sensitivity of a portfolio's returns to changes in foreign exchange rates.
What is Currency Exposure?
Currency exposure (also called FX exposure or foreign exchange risk) is the degree to which an investor's portfolio returns are affected by fluctuations in exchange rates between the investor's home currency and the currencies of foreign assets. When a US investor holds European stocks denominated in euros, a strengthening dollar reduces the dollar-denominated return even if the euro stock price is unchanged, and vice versa. Currency exposure can be transaction exposure (specific known cash flows in foreign currencies), translation exposure (converting foreign subsidiary financials), or economic exposure (long-run competitive effects of currency changes on a firm's value). Investors manage currency exposure through hedging instruments such as currency forward contracts, options, and currency-hedged ETFs. The decision to hedge or remain exposed involves weighing hedging costs, forecasting uncertainty, and the portfolio's time horizon.
Example
A US investor buys 100 shares of a German company at €50 per share when EUR/USD is 1.10, investing $5,500. A year later the stock rises 10% to €55, but EUR/USD falls to 1.00. The investor's euro return is +10%, but the dollar-denominated value is now $5,500 — flat — because the currency loss exactly offset the equity gain. The investor bore significant currency exposure without hedging.
