The Dollar Effect: What Currency Movements Mean for African Investors

Why investing in global markets means paying attention to both asset performance and exchange rates

When African investors invest in global markets, the performance of the investment itself is only part of the story. Currency movements can have a significant impact on the final return when an investment is denominated in a foreign currency, particularly the U.S. dollar.

The U.S. dollar has recently strengthened against several major currencies, while the euro has come under pressure amid concerns surrounding European fiscal and political conditions. These developments highlight an important but sometimes overlooked aspect of international investing: foreign-exchange risk.

The Two Sources of Return

A simple way to understand international investing is to recognise that an investor’s return can come from two sources: the performance of the investment and the movement of the currency in which that investment is denominated.

In simple terms: Your return = Investment performance ± Currency movement

For example, imagine an African investor purchases a U.S. dollar‑denominated ETF. If the ETF rises by 10%, the investment has generated a 10% return in dollar terms. However, that does not necessarily mean the investor has earned exactly 10% when the investment is converted back into their local currency. If the investor’s local currency strengthens against the dollar during the same period, part of the investment gain could be offset. Conversely, if the local currency weakens against the dollar, the currency movement could increase the investment’s value when converted back.

This means that two investors holding exactly the same global asset can experience different returns when those returns are measured in their respective home currencies.

Why This Matters to African Investors
 

For investors in Uganda, Kenya, Nigeria and other African markets, investing internationally introduces an additional layer of consideration. An investor may buy U.S. equities, global ETFs, REITs, technology companies or bond funds, many of which are denominated in U.S. dollars. The underlying asset may perform well, but the USD‑to‑local‑currency exchange rate can influence what that performance ultimately means for the investor.

Consider a simple example: Suppose an investor converts UGX 10 million into U.S. dollars and invests in a USD‑denominated ETF. If the ETF gains 10%, the investment has increased by 10% in dollar terms. But the investor should then ask another question: what happened to the UGX/USD exchange rate during the same period?

If the Ugandan shilling weakened against the dollar, the investment could be worth considerably more when converted back. If the shilling strengthened, however, some of the investment gain could be offset. The important lesson is that looking only at the headline return of an international investment does not always provide the complete picture for an African investor.

Currency Is Not Simply a Risk to Avoid

Currency exposure is not necessarily something investors should view negatively. In fact, holding assets denominated in different currencies can contribute to portfolio diversification. The more important consideration is whether the investor understands the currency exposure that comes with an international investment. This includes knowing:

  • What currency the investment is denominated in
  • What currency the investor ultimately measures their wealth in
  • How exchange‑rate movements could affect the investment
  • Whether their investment horizon makes short‑term currency fluctuations less significant

For a long‑term investor, attempting to predict every movement in the dollar may be less important than building a diversified portfolio and understanding how different assets and currencies interact.

What Investors Should Watch

As global markets navigate shifting interest rates, government debt concerns, geopolitical uncertainty and uneven growth prospects, currency markets will remain central to the investment landscape. African investors should therefore pay attention not only to the performance of individual companies, ETFs or securities, but also to:

  • Interest rate policy
  • Central bank decisions
  • Government finances
  • Commodity price trends
  • Global capital flows

The GoldKach Perspective

At GoldKach, we believe that access to global markets should come with a strong understanding of those markets. International investing gives African investors exposure to industries and opportunities not readily available domestically. But it also requires navigating currency movements, interest rates, and geopolitical developments. The objective is not to predict every dollar swing or perfectly time the currency market. Instead, it’s about understanding the forces driving currencies and considering how foreign exchange exposure fits within a broader investment strategy.

Ultimately, global investing means thinking beyond the stock market. When an African investor buys an international asset, they are participating not only in the performance of that asset but also in the foreign exchange environment surrounding it. Global markets create opportunities. Understanding currencies helps investors navigate them.
