Currency Risk (also known as '[[Exchange-Rate Risk]]' or '[[Foreign Exchange Risk]]') is the financial peril you face when an investment's value changes due to fluctuations in currency exchange rates. Imagine you're an American investor buying shares in a fantastic French company. Your [[US Dollars]] are converted into [[Euros]] to make the purchase. Later, you sell the shares for a handsome profit //in Euros//. But what if, during that time, the Euro has weakened against the Dollar? When you convert your proceeds back, you might find your profit has shrunk or even turned into a loss. This isn't because the company performed poorly, but because the currency you were temporarily holding lost value relative to your home currency. It's a crucial, often overlooked, layer of risk for anyone venturing into international markets, turning a seemingly straightforward investment into a two-part bet: one on the asset and another on the currency.
===== How Does Currency Risk Work? =====
The mechanics are best understood with a quick story. At its heart, currency risk is the difference between an investment's performance in its local currency and its performance in your home currency.
==== A Practical Example ====
Let's follow an investor named //Jane from Chicago//.
  * Jane wants to buy shares in "Le Fromage Fabuleux," a Swiss cheese company listed on the Zurich stock exchange. The stock trades in [[Swiss Francs]] (CHF).
  * She decides to invest $11,000. At the time of purchase, the [[exchange rate]] is 1.10 USD for every 1.00 CHF. So, her $11,000 gets her CHF 10,000 worth of stock ($11,000 / 1.10 = CHF 10,000).
  * A year passes. The cheese business is booming! The stock value has risen by 20% to CHF 12,000. Jane is thrilled.
  * However, the US economy has strengthened, and the Swiss Franc has weakened against the dollar. The new exchange rate is 1.00 USD for every 1.00 CHF (this is known as 'parity').
  * Jane decides to sell her shares and bring her money home. She converts her CHF 12,000 back into dollars. At the new rate, she gets exactly $12,000.
Her stock //gained 20%//, but her total return in US Dollars is only 9% ($1,000 profit on a $11,000 investment). The other 11% of potential profit was wiped out by the unfavorable currency swing. That's currency risk in action.
===== Why Should a Value Investor Care? =====
A devoted [[value investing]] practitioner like [[Warren Buffett]] is obsessed with understanding the true, underlying value of a business and buying it with a comfortable [[margin of safety]]. Currency risk directly impacts this calculation. If you analyze a German automaker and decide it's worth €100 per share, that conclusion is incomplete. You must also consider the potential journey of the Euro against your home currency. A sharp, unfavorable move in the exchange rate can erode your margin of safety just as surely as a drop in the company's earnings.
While long-term value investors generally don't try to predict currency movements, they must acknowledge the risk. Some savvy investors look for companies with a 'natural hedge.' For instance, an American investing in a Japanese company like Toyota, which earns a significant portion of its revenue in US dollars, has a built-in buffer against a weakening Yen.
===== Taming the Beast: Managing Currency Risk =====
You can't eliminate risk, but you can certainly manage it. When it comes to currency risk, investors generally have two schools of thought: active hedging or a strategic 'do nothing'.
==== Hedging Strategies ====
[[Hedging]] is essentially buying financial insurance against adverse currency moves. It's a way to lock in an exchange rate and remove uncertainty. While it sounds great, it's not free and can be complex.
  * **For Sophisticated Investors:** Professionals often use instruments like [[currency forwards]] or [[futures contracts]] to agree on a future exchange rate today. This is generally not the playground for the average retail investor.
  * **For Everyday Investors:** A more accessible route is through currency-hedged [[Exchange-Traded Funds]] ([[ETFs]]). For example, a "Japan Hedged to USD" ETF will invest in Japanese stocks but use financial instruments to strip out the effect of Yen-to-Dollar fluctuations. You get the performance of the stocks, not the currency. The catch? These funds have higher fees, which can eat into your long-term returns.
==== The 'Do Nothing' Approach ====
This might sound counterintuitive, but for many long-term value investors, the best strategy is often to do nothing at all. Here’s the logic:
  * **Costs vs. Benefits:** Hedging isn't free. The fees and transaction costs create a constant drag on your performance. Over many years, this can significantly reduce your compounding power.
  * **Long-Term Reversion:** Over decades, currency exchange rates tend to fluctuate around a long-term average. The wild swings that cause headaches in the short term often even out over a true value investor's time horizon (10, 20, or 30+ years).
  * **Focus on the Business:** The core of value investing is finding wonderful businesses at fair prices. If you've done your homework correctly, the growth in the business's intrinsic value should far outstrip any noise from currency markets in the long run. Let the business performance do the heavy lifting.
  * **Diversification:** Owning great international businesses across several different currency zones provides its own form of risk management. A weak Euro might be offset by a strong British Pound in another part of your portfolio.
