Fund currency ≠ your currency risk
The currency a fund is priced/traded in (its trading currency) does not change your risk. A US-stock ETF exposes you to the US dollar via its holdings, whether you buy the USD, EUR or GBP line. Buying the EUR-traded share class of an unhedged S&P 500 fund still leaves you with USD exposure — only the display currency changes.
What currency hedging actually does
A currency-hedged share class (often marked *EUR Hedged* / *GBP Hedged*) uses forward contracts to neutralise the foreign-currency movements of the underlying holdings — so a EUR-hedged S&P 500 ETF aims to remove the EUR/USD swing, leaving just the stocks' performance.
The trade-offs
- Cost — hedging adds a small ongoing cost and a higher TER, and interest-rate differences between currencies can help or hurt.
- Reduced diversification — currency exposure can actually *reduce* portfolio volatility for some investors, so hedging it away isn't always better.
- Tracking — hedged share classes track the hedged index, not the headline one, so returns can diverge noticeably.
When hedging makes sense
- Bonds — currency swings can dwarf the yield, so currency-hedged bond ETFs are common and often sensible.
- Short horizons / spending soon — if you'll convert to your home currency soon, hedging reduces timing risk.
- Broad global equities, long horizon — most long-term equity investors leave it unhedged; currency tends to wash out over decades and unhedged is cheaper.
