Currency-hedged or not? Hedged vs unhedged ETFs
A currency-hedged ETF tries to cancel out foreign-exchange swings, so you get closer to the market’s own return; an unhedged one lets the currency move with you, for better or worse.
What currency does to your return
Say you buy a fund full of US companies. Your return now has two moving parts: how those companies perform, and how the dollar moves against your home currency. If the dollar strengthens while you hold the fund, that is a tailwind on top of any market gain; if it weakens, it eats into your return even if the companies did well. The The currency the fund reports in. You can often buy it in another currency; that does not change what it holds. More → at your broker — euros, pounds, dollars — does not change this. What matters is the currencies of the assets the fund holds, not the label on the share class. A euro-denominated share class of a US equity fund still gives you full dollar exposure; the euro label only describes the price on your screen, not the underlying risk.
What hedging does
A currency-hedged share class uses rolling forward contracts to cancel out most of that exchange-rate movement, so your return ends up close to what the underlying market delivered in local terms. If the US market rose 10% but the dollar fell 4% against your currency, an unhedged fund would return roughly 6%; a hedged version would return closer to 10%. The key word is ‘closer’ — hedging is never perfect. It is rebalanced periodically (typically daily or monthly), so small residual currency effects still slip through, especially in fast-moving markets. An unhedged fund skips all of this; you simply ride the currency along with the market.
What hedging costs
Hedging is not free. The cost shows up as a small ongoing drag on the hedged share class, typically reflected in a slightly higher The yearly running cost of the fund, shown as a % of your money. Lower is cheaper. More → or an implicit carry cost built into the forward contracts. The size of that cost depends on the interest-rate difference between the two currencies: when US rates are meaningfully higher than eurozone rates, for example, a European investor hedging dollar exposure pays a real premium. In low-rate environments the cost can be negligible; in high-rate-differential periods it can chip away at the return noticeably. This is one reason the hedged vs unhedged decision is worth revisiting if the rate environment shifts significantly over time.
When people hedge — and when they don’t
A rough rule of thumb many beginners encounter: for long-term global stock holdings, currency swings have historically tended to wash out over long enough periods, and many investors leave them unhedged for simplicity and lower cost. The logic is that over a decade or more, the currency effects are noise compared with the equity return itself. Hedging shows up more with bonds — where currency wobble can easily dwarf the modest income a bond delivers — and with money you will need sooner, where a bad currency year at the wrong moment hurts. Neither stance is a universal rule; it depends on your timeline, your home currency, and how much exchange-rate noise you want to filter out.
Currency exposure as a feature
It is worth noting that currency exposure is not purely a risk to be managed away. If you are a UK investor holding a dollar-heavy world fund and sterling weakens, that currency move boosts your fund’s value in pounds — which can provide a meaningful cushion in times of domestic economic stress. For some investors, that correlation — where the pound sometimes weakens when the UK economy is struggling — is a feature rather than a bug: the global fund partly offsets bad local news. Hedging away the currency removes the drag in the bad direction but also removes that cushion in times of domestic pressure. Neither outcome is free; you are always choosing which mix of risks to carry.
How to spot a hedged share class
Fund names give you the clue: a hedged share class almost always carries a label like (EUR Hedged), (GBP H), or simply H appended to the share-class name. The same underlying fund often has both an unhedged and a hedged version trading side by side with different ISINs. When comparing on a fund platform, check the full share-class name rather than just the fund family name, because the two versions look identical until you read that label. Picking the wrong one by accident is easy; a quick ISIN check against the fund factsheet takes ten seconds and confirms which version you are actually buying. This is the lay of the land, not a recommendation on which to choose.
