Quick Answer
Exchange rate swings change what a foreign investment is worth once converted back to dollars: a stronger dollar hurts U.S. holders of foreign securities, a weaker dollar helps them. Sovereign debt carries no bankruptcy court to fall back on. Geopolitical events, wars, sanctions, regime change, add volatility, currency pressure, and capital flight risk on top of ordinary market risk.
These three factors (currency, sovereign credit, and geopolitics) all fall under systematic risk, meaning an investor cannot diversify them away by simply holding more foreign securities in the same affected market. The sections below cover how each one specifically moves returns.
How Do Exchange Rates Affect Foreign Investment Returns?
- Exchange rate: the price of one currency expressed in terms of another
- Exchange rate fluctuations directly affect the returns on international investments
Effect on U.S. investors holding foreign investments:
| Foreign Currency Movement | Effect on U.S. Investor Returns |
|---|---|
| Foreign currency appreciates vs. USD | Returns increase when converted back to USD |
| Foreign currency depreciates vs. USD | Returns decrease when converted back to USD |
| USD strengthens (appreciates) | Foreign investment returns decrease in dollar terms |
| USD weakens (depreciates) | Foreign investment returns increase in dollar terms |
- Currency (exchange rate) risk: the risk that changes in exchange rates will reduce the value of foreign investments
- A strong dollar hurts U.S. investors in foreign securities (foreign returns worth less in USD)
- A weak dollar benefits U.S. investors in foreign securities (foreign returns worth more in USD)
- Currency risk is a form of systematic risk; it cannot be diversified away within a single foreign market
Exam Tip: Gotchas
- A strengthening dollar hurts U.S. investors in foreign securities (foreign returns convert to fewer dollars). A weakening dollar helps them (foreign returns convert to more dollars). The exam tests the direction of currency impact on returns, not just the vocabulary.
What Is Sovereign Debt Risk?
- Sovereign debt: debt issued by a national government, typically denominated in its own currency
- Sovereign risk: the risk that a foreign government may default on its debt obligations, impose capital controls, or face political instability
- Credit quality varies widely, from AAA-rated developed nations to speculative-grade emerging markets
- Sovereign default has no bankruptcy court; recovery depends on negotiation
- Sovereign credit ratings affect the country's borrowing costs and exchange rate
What Are Geopolitical Factors?
- Geopolitical risk: the risk that political events, conflicts, or policy changes in a country or region will negatively affect investments
- Examples: wars, trade disputes, sanctions, regime changes, regulatory shifts, nationalization of assets
- Geopolitical events can cause market volatility, currency depreciation, and capital flight
- Affects both equity and fixed income investments in affected regions
- Considered a form of systematic risk for investments in that region
What Should You Check on Exam Day?
- Trace the direction of the dollar through to the investor's return: a strong dollar hurts foreign-currency returns converted back to USD, a weak dollar helps them
- Remember sovereign default has no bankruptcy court; recovery is negotiated, not litigated
- Treat currency risk, sovereign risk, and geopolitical risk as forms of systematic risk that diversification within the same foreign market cannot remove
- Connect geopolitical events (wars, sanctions, regime change, nationalization) to their typical effects: volatility, currency depreciation, and capital flight
