Unhedged Currency Exposure

The risk of investment returns being affected by fluctuations in foreign exchange rates because currency hedges are not utilized.

Unhedged currency exposure occurs when an investor holds international assets denominated in foreign currencies without using derivative contracts, such as forward contracts or options, to lock in exchange rates. Consequently, the investor's total return is shaped by two distinct forces: the performance of the underlying asset in its local market and the movement of the foreign currency relative to the investor's home currency. This exposure introduces a secondary layer of volatility to international investing. If the foreign currency strengthens against the investor's home currency, it acts as a tailwind, boosting the total return when the asset is converted back. Conversely, if the home currency strengthens, it acts as a headwind, reducing or potentially erasing any gains made by the underlying asset. Investors often choose unhedged vehicles when they want to express a bullish view on a foreign currency or when they believe the cost of currency hedging outweighs the volatility protection it provides. However, a common pitfall is failing to realize how significantly exchange rate fluctuations can decouple an investor's actual return from the local performance of the underlying stock or bond.

A U.S. investor purchases shares of a Japanese company for 10,000 Yen when the exchange rate is 100 Yen per USD, making the initial investment $100. Over the year, the stock price rises 10% to 11,000 Yen. However, the Yen depreciates to 115 Yen per USD. When converting back, the investment is worth 11,000 / 115 = $95.65. Despite a 10% local stock gain, the unhedged currency exposure results in a net loss of 4.35% in USD terms.
