Currency risk: what happens when you invest in dollars but live in lei, złoty or won

If you live outside the US and buy a world or US stock fund, part of your return depends on something you didn’t choose: the exchange rate between your currency and the currencies of the companies you own.

How it works

Say you invest 1,000 in your local currency into a US fund. Over a year:

• the fund rises 10% in dollars, but
• the dollar falls 5% against your currency.

In your own currency, your return is roughly +4.5%, not +10%. If the dollar had risen 5% instead, you’d be up about 15.5%.

Over short periods, currency moves can be as large as stock moves. Over long periods, they tend to matter less than the growth of the companies themselves — but they never disappear.

The trading currency doesn’t change the risk

A common misunderstanding: buying a US-stock ETF listed in euros doesn’t remove dollar risk. The fund still owns US companies valued in dollars; the euro price simply reflects the dollar price converted. What the listing currency changes is your conversion cost, not your exposure.

Currency-hedged funds

Some ETFs are hedged to your currency (often marked “EUR Hedged” or “GBP Hedged”). They use contracts to cancel most of the effect of exchange-rate moves.

• Pros: smoother returns in your own currency.
• Cons: extra costs, and you lose the diversification benefit of holding other currencies.

Hedging is more common for bonds, where currency swings can overwhelm the small returns. For long-term stock investors, many choose not to hedge.

Practical tips

• If your expenses are in your local currency, consider keeping your emergency fund and short-term money in that currency.
• Compare brokers on FX fees: you pay them every time you convert. More on fees.
• If your currency has a history of sharp falls, owning assets in other currencies can actually protect your purchasing power.

The short version

Foreign investments carry currency risk. It’s real in the short term, smaller over decades, and the ETF’s listing currency doesn’t remove it. Hedge bonds if you like; for stocks, many long-term investors accept the currency swings.
