International investments can provide diversification, higher returns, and exposure to emerging markets. However, they also come with additional risks, particularly currency risk, also known as foreign exchange (FX) risk. Exchange rate fluctuations can significantly impact investment returns, sometimes eroding potential gains or magnifying losses.

Managing currency risk is essential for investors who allocate capital across multiple countries. This guide explores the nature of currency risk, its effects on different asset classes, and various strategies to mitigate its impact.

Understanding Currency Risk

What is Currency Risk?

Currency risk refers to the possibility that exchange rate fluctuations will affect the value of investments held in foreign currencies. It arises because exchange rates are constantly changing due to economic, political, and market factors.

For example, a UK investor purchasing US stocks will see the value of their investment influenced not only by stock price movements but also by changes in the GBP/USD exchange rate. If the pound strengthens against the dollar, the value of the investment in GBP terms decreases, even if the stock price remains unchanged.

Key Factors Influencing Currency Movements

Several factors drive exchange rate fluctuations:

1. Interest Rates – Higher interest rates attract foreign capital, strengthening the currency.

2. Inflation Rates – Countries with lower inflation tend to have stronger currencies.

3. Economic Stability – Stronger economies attract investment, boosting currency value.

4. Trade Balances – Countries with trade surpluses often have stronger currencies.

5. Political and Geopolitical Events – Political uncertainty can weaken a currency.

6. Market Sentiment and Speculation – Traders and investors influence short-term currency movements.

Types of Currency Risk

1. Transaction Risk

Transaction risk arises when businesses or investors conduct transactions in a foreign currency. If the exchange rate moves unfavourably before settlement, they may suffer losses.

Example:

• A UK company orders machinery from Germany, payable in euros (EUR). If the EUR/GBP exchange rate changes before payment, the company may pay more than expected.

2. Translation Risk

This risk affects companies with overseas operations. When financial statements are translated into the home currency, fluctuations can impact reported earnings.

Example:

• A UK multinational earns revenue in US dollars (USD). If GBP appreciates against USD, the reported earnings in GBP decline, even if US sales remain strong.

3. Economic Risk

Economic risk is the long-term impact of currency fluctuations on a company's or country's competitiveness. A stronger currency can make exports more expensive, reducing global demand.

Example:

• If the British pound strengthens, UK exports become more expensive, potentially reducing sales in foreign markets.

How Currency Fluctuations Impact Investment Returns

Equity Investments

• If a UK investor buys US stocks, a weakening GBP/USD exchange rate increases investment value when converted back to GBP.

• If GBP strengthens, the investor loses value despite stock price gains.

Fixed-Income Securities

• Foreign bonds can offer attractive yields, but if the currency depreciates, returns can be wiped out.

• Local-currency government bonds carry added FX risk compared to corporate bonds denominated in a stable currency like USD.

Real Estate and Commodities

• Foreign real estate investments are directly affected by currency movements.

• Commodities like gold and oil are often priced in USD, meaning investors must consider exchange rate impacts.

Strategies to Manage Currency Risk

1. Hedging Strategies

Investors use financial instruments to hedge against currency risk.

Forward Contracts

A forward contract locks in an exchange rate for a future date, eliminating uncertainty.

• Example: A UK importer agrees to pay USD 1 million in six months and secures a fixed GBP/USD rate today.

Futures Contracts

Similar to forwards but traded on exchanges, currency futures help investors hedge against fluctuations.

• Example: A UK investor holding US stocks can use GBP/USD futures to protect against currency movements.

Options and Swaps

• Currency options give the right (but not the obligation) to buy or sell currency at a specific rate.

• Currency swaps allow firms to exchange cash flows in different currencies over time.

2. Diversification Strategies

Multi-Currency Portfolios

Holding assets across different currencies reduces exposure to any single currency fluctuation.

Geographic Diversification

Investing in multiple countries and industries spreads currency risk and enhances resilience.

3. Natural Hedging

This involves structuring operations to offset currency exposure.

• Matching revenues and expenses in the same currency

• Using local currency financing to reduce FX risk in foreign investments

Currency-Hedged vs. Non-Hedged Investments

Hedged Investments

Pros:
✔ Protect against FX risk
✔ Provide stable returns
✔ Reduce volatility

Cons:
✖ Can be costly (hedging fees)
✖ May miss out on favourable currency movements

Non-Hedged Investments

Pros:
✔ No hedging costs
✔ Potential to benefit from currency appreciation

Cons:
✖ Increased risk from currency fluctuations

Investors must decide whether to hedge based on risk tolerance and investment goals.

Role of Central Banks and Government Policies

How Interest Rate Changes Impact Currency Risk

• Higher rates attract foreign investors, strengthening a currency.

• Lower rates can weaken a currency, benefiting exporters.

Effect of Monetary Policy on Exchange Rates

• Quantitative easing (QE) can weaken a currency by increasing money supply.

• Tight monetary policy strengthens the currency but can slow economic growth.

Case Studies: Historical Currency Fluctuations & Investment Impact

1. Brexit and the British Pound

• The GBP/USD fell 10% overnight after the Brexit vote, impacting UK investors holding US assets.

2. US Dollar and Emerging Markets

• A strong USD increases debt burdens in emerging markets that borrow in USD, affecting bond investors.

3. Japanese Yen as a Safe Haven

• The JPY often strengthens during market downturns, affecting global investments.

Tools and Resources for Managing Currency Risk

1. Currency Risk Calculators – Help investors estimate FX impact on investments.

2. FX Risk Assessment Platforms – Provide real-time exchange rate forecasts.

3. Economic Calendars – Track central bank decisions and economic data releases.

Bringing It All Together

Currency risk is an unavoidable aspect of international investing. By understanding how exchange rates impact returns, investors can make informed decisions to protect their portfolios.

Key Takeaways:

✔ Use hedging strategies (forwards, futures, options) to mitigate risk.
✔ Diversify across currencies and regions.
✔ Consider natural hedging and currency-hedged investments.
✔ Monitor central bank policies and macroeconomic trends.

A well-planned approach to currency risk management ensures long-term investment success, allowing investors to reap the benefits of global diversification without undue exposure to foreign exchange volatility.
