FX risk in YOUR portfolio

Buy a US index fund with euros and you own two bets, whether you meant to or not: the S&P 500 AND the dollar. If Wall Street rises 10% but the dollar drops 10% against the euro, your euro-measured gain is roughly zero. Most long-term investors never notice this, until the year it decides their entire return.

What you get asked

  1. You're a euro investor holding an S&P 500 ETF. Your real return depends on:

    The fund's assets live in dollars, but you eat, rent and retire in euros. Both legs count. Standard (unhedged) ETFs pass the currency move straight through to you.

  2. You invest €10,000 in a US fund. In dollars it gains 20%, but the dollar falls 10% against the euro. Roughly what is your holding worth in euros?

    €10,000 × 1.20 × 0.90 = €10,800. The 20% headline gain shrinks to 8% in your currency. The dollar quietly took the rest.

  3. In 2022 the S&P 500 fell about 19% in dollars, yet euro investors lost noticeably less. Why?

    The dollar gained roughly 6% on the euro in 2022, cushioning the fall for euro holders. FX risk cuts both ways: some years it wounds you, some years it's free armour.

  4. Match each fund choice to its currency consequence

    There's no free option: hedging costs a little every year, staying home concentrates you, going global dilutes but never deletes FX. Pick consciously rather than by accident.

  5. For a euro investor holding global stocks for DECADES, currency swings are usually:

    Over decades, major-currency swings mostly cancel out, while the businesses you own keep compounding. Know the risk exists, diversify across it, then let time do the hedging for free. 🐜
