Currency Is Half Your International Return: Hedged vs Unhedged ETFs
August 19, 2026 · 2 min read · by ETFWinner Research
When you buy a foreign fund you make two bets, and only one of them is about companies. Hedging removes the second — at a price.
Buy a Japanese or European fund and your return has two moving parts: what those companies did, and what happened to the exchange rate between their currency and yours. Investors track the first obsessively and discover the second only when it goes against them.
How the two returns combine
If a foreign market rises 10% in its own currency but that currency falls 8% against yours, your return is roughly 2%. The companies performed; the translation ate it. Reverse the currency move and a mediocre local return becomes an excellent one.
Over a single year this can dominate everything else. Over twenty years, currency effects tend to partially wash out — which is the core argument for not bothering to hedge if your horizon is genuinely long.
What a hedged fund does
A hedged fund such as HEFA holds the same shares as its unhedged sibling but adds currency forward contracts to cancel out exchange-rate movement. You get the local-market return, translated at a fixed rate, minus the cost of running the hedge.
That cost shows up two ways: a higher expense ratio — 0.35% against 0.07% for the unhedged version — and the interest-rate differential between the two currencies, which can be a meaningful drag or occasionally a benefit.

|---|---|---|---|---|---|
| EFA | iShares MSCI EAFE ETF | 0.32% | 11.85% | 2.75% | $58B |
| HEFA | iShares Currency Hedged MSCI EAFE ETF | 0.35% | — | — | $8B |
| IEFA | iShares Core MSCI EAFE ETF | 0.07% | 8.50% | 2.85% | $110B |
When hedging earns its cost
- Short horizons. If you need the money within a few years, currency volatility is a real risk rather than noise that averages out.
- Bonds, always worth considering. Currency swings can exceed a bond fund's entire yield, which makes unhedged foreign bonds a strange holding for a defensive allocation.
- When your currency is structurally strengthening. A persistent trend is not noise, and unhedged foreign holdings bleed against it.
When it is not worth it
For long-horizon equity investors, the honest case for hedging is weak. You pay a permanent cost to remove a risk that has historically been roughly symmetrical over decades, and you give up the diversification benefit of holding assets that rise when your own currency falls.
There is also a subtle point worth remembering: for investors in smaller or more volatile currencies, unhedged foreign equity is itself a hedge. The currency exposure you would be paying to remove may be the most valuable protection in the portfolio.

Frequently asked questions
Should I buy currency-hedged ETFs?
For long-horizon equity holdings, usually not — hedging costs are permanent while currency effects tend to average out. For short horizons and for foreign bonds, hedging is far easier to justify.
How much can currency affect ETF returns?
Substantially. Exchange-rate moves of ten percent or more in a year are common and can exceed the underlying market return entirely.
Why do hedged ETFs cost more?
They must buy and roll currency forward contracts continuously, which adds both a higher expense ratio and the cost of the interest-rate differential between the two currencies.
Is unhedged exposure risky for investors in volatile currencies?
It cuts both ways. Foreign-currency assets often rise in local terms when a home currency weakens, which is why unhedged holdings can act as protection rather than added risk.
