The success or failure of international investment ventures heavily depends on how currency values change over time. International investors must understand currency dynamics as it is a fundamental requirement for successful investing abroad.

This article examines how currency values change together with their underlying causes while assessing their consequences on different investment strategies and proposing ways to manage currency risks.

What Are Currency Fluctuations?

Currency fluctuations represent the variations in the value of one nation's currency when compared with another country's currency. The British pound (GBP) might appreciate against the US dollar (USD) or the USD could appreciate against GBP for a certain duration. Global commerce and investment activities are driven by exchange rate variations resulting from currency movements.

Small changes in exchange rates impact the expenses of foreign market investments and the resulting profits. When currencies move positively they increase profits but when they move negatively they reduce profits.

What Drives Currency Fluctuations?

The value of currencies changes because multiple related elements affect them.

• Interest Rates: Central banks use interest rate changes to control inflation levels while also influencing economic growth rates. When interest rates rise they draw foreign investors who are looking for better investment returns which results in increased demand for that country's currency.
• Inflation Rates: Currencies from nations that maintain lower inflation levels appreciate because their purchasing power grows compared to countries experiencing higher inflation.
• Trade Balances: When a country experiences a trade surplus because its exports surpass imports it usually results in an increase in the nation’s currency value whereas a trade deficit causes the currency to lose strength. The demand for currencies increases alongside the demand for goods when countries exhibit trade surpluses.
• Geopolitical Events: Currency values become unstable during times of political unrest and elections as well as trade wars and natural disasters. Brexit created substantial changes to the pound’s standing in global markets.

International investors must understand these factors because they establish the potential opportunities and risks arising from currency volatility.

How Currency Fluctuations Impact Investments

Changes in currency values can produce major impacts on the performance of different asset classes in investment portfolios.

Stocks

Investing in international stock markets exposes investors to currency movements which can boost or diminish their financial returns. When you invest in US stocks as a UK investor and the USD appreciates against the GBP you get higher returns when you convert your earnings back to pounds. The depreciation of the USD reduces your profit margin despite strong stock performance.

Example:

• Positive Impact: A £10,000 investment in US stocks produces a 10% return. When the USD increases by 5% your profitability will reach 15% after converting back to GBP.
• Negative Impact: When a stock returns 10% but there is a 5% decrease in USD value the total profit ends up at 5%.

Commodities

Most commodities such as gold and crude oil have their prices set in US dollars. Currency shifts in the dollar have immediate consequences on international investors' commodity prices and returns. Non-USD investors face higher commodity costs when the dollar strengthens which reduces demand and pushes prices down.

Bonds

Bonds from foreign nations carry a high level of vulnerability to currency risk. Currency depreciation may eliminate any interest earnings achieved from a bond's steady yield. Investing in bonds denominated in stable currencies such as the Swiss franc (CHF) reduces currency risk while typically offering lower yields.

Real Estate

Investing in foreign real estate presents potential gains but remains vulnerable to fluctuations in currency values. Suppose you purchase property in Australia. If you plan to bring back profits from Australian investments to your home country and the Australian dollar weakens against your domestic currency then the value of your investment will decline.

Real-World Examples

These cases illustrate how currency volatility affects financial decisions and investments.

• Post-Brexit Pound: The pound fell roughly 15% against the dollar following the 2016 Brexit referendum. Investors based in the UK who owned US stocks or assets experienced financial benefits because the reduced value of the pound increased the value of their returns upon conversion to GBP.
• Asian Financial Crisis (1997): The Thai baht collapse led to significant currency value drops among multiple Asian nations. Global investments in Thailand, Indonesia and South Korea suffered steep declines which eliminated billions in market value.
• 2020 Pandemic USD Spike: The onset of COVID-19 saw global investors move their funds into the USD due to its reputation as a "safe haven" asset. Emerging-market investors who borrowed in U.S. dollars faced challenges when their returns were generated in weaker local currencies due to the dollar's rapid appreciation.

Risks and Opportunities for International Investors

The Risks

• Exchange Rate Depreciation: International investors face major hurdles when the target country's currency loses value and reduces their expected returns. Long-term investments face amplified risks from unpredictable future currency values.
• Market Uncertainty: The unpredictability of international markets grows because currency fluctuations amplify market volatility.
• Economic Instability: When a country's currency experiences rapid changes it indicates underlying economic issues like inflation or political problems.

The Opportunities

• Favourable Currency Movements: Investing in foreign currency when its value is low and selling when its value rises can greatly increase profit margins.
• Diversification: Portfolio risk decreases through currency movements when investments span different regions and currencies.

Strategies to Manage Currency Risks

Investors with the right strategies can effectively manage the risks from unavoidable currency fluctuations.

• Hedging with Currency Futures or Options: Through financial tools such as currency futures and options investors have the ability to secure exchange rates or shield themselves from potential market declines. Despite their limitations they remain a favored method for protecting against currency market fluctuations.
• Investing in Multinational Companies: Multinational companies that earn income from various countries benefit from automatic currency risk protection. Companies such as Unilever and Apple achieve currency risk mitigation through their multiple revenue streams across different regions.
• Holding Assets in Stable Currencies: Investments in stable currencies such as USD, CHF and JPY can protect investors from currency risks during periods of economic instability.
• Using Currency ETFs: Investors can use actively managed currency exchange-traded funds (ETFs) to protect their portfolios from currency fluctuations while accessing international markets.
