Hedged vs Unhedged ETFs for Canadians: What You're Actually Choosing

The mechanism

When you buy a Canadian-listed ETF tracking the S&P 500, your money buys U.S. stocks, which are priced in U.S. dollars. Your return therefore has two components:

Return = index performance + currency movement

If the S&P 500 rises 10% and the U.S. dollar strengthens 5% against the Canadian dollar, an unhedged Canadian investor earns roughly 15%. If the loonie strengthens 5% instead, that same investor earns roughly 5%.

A hedged ETF uses forward contracts to neutralize the currency leg. It aims to deliver approximately the 10% index return in both scenarios.

The comparison

That last row is the one most Canadian investors underweight. The Canadian dollar is a commodity-linked currency that tends to weaken during global risk-off events, exactly when equity markets fall. For an unhedged Canadian holder of U.S. equities, that currency move partially offsets the equity loss. It is an accidental but real diversification benefit that hedging removes.

What hedging actually costs

Hedging is not free, and the cost is not just the slightly higher MER.

Interest rate differential. Currency forwards are priced off the interest rate gap between the two currencies. When U.S. rates exceed Canadian rates — as they have through much of this cycle, with the Bank of Canada at 2.25% — hedging into Canadian dollars carries an ongoing drag roughly equal to that differential.

Rebalancing friction. Hedges are typically reset monthly. Between resets, the hedge ratio drifts as markets move, producing imperfect coverage and small realized costs.

Compounding tracking error. Individually tiny, these differences compound. Over a decade, hedged and unhedged versions of the same index can diverge meaningfully even before accounting for the currency move itself.

Why 2026 makes this question live again

Currency markets have been unusually active. The yen fell to a forty-year low near 163 per dollar, prompting confirmed joint U.S.-Japan intervention. Japanese institutions have been repatriating capital, selling roughly $29.6 billion of U.S. debt in Q1 2026. European yields have risen enough that German 10-year yields have run above U.S. 10-year yields swapped into euros — a reversal of the pattern that held for most of the previous decade, creating incentives for European capital to come home too.

Large, simultaneous repatriation flows are exactly the conditions under which currencies move more than equity investors expect. That does not tell you which way the loonie goes. It tells you the currency component of your return is likely to be larger in magnitude than it has been in calm periods — which raises the stakes of the hedged/unhedged decision in both directions.

How to actually decide

Skip the forecasting. Ask three questions.

1. What currency are your future liabilities in?

If you will retire in Canada, spend Canadian dollars and buy Canadian groceries, your liabilities are in CAD. That is a genuine argument for hedging some foreign exposure. If you spend winters in the U.S., own U.S. property, or expect significant USD spending, unhedged exposure is a natural match.

2. What is your time horizon?

Currency effects tend to be mean-reverting over very long periods and dominant over short ones. For a 25-year horizon, the currency contribution to total return has historically been modest relative to equity returns. For a five-year horizon, it can be the largest single factor.

3. Can you tolerate the tracking difference psychologically?

This is underrated. An unhedged investor who watches the S&P 500 rise 12% while their Canadian-listed ETF returns 4% because the loonie rallied will be tempted to switch — usually at the worst moment. Choose the version whose behaviour you can hold through.

A reasonable default

For most Canadians building long-term equity exposure, unhedged is the more common default, for three reasons: it is cheaper, it provides a natural crisis cushion when the loonie falls, and over multi-decade horizons the currency effect tends to wash out relative to equity returns.

The strongest cases for hedging are shorter horizons, money earmarked for a specific CAD expense, and fixed income — where currency volatility can easily exceed the yield you are trying to earn, making an unhedged foreign bond fund an equity-like risk in a bond-shaped wrapper.

Remember also that hedged and unhedged are not the only lever: the withholding tax treatment of U.S. dividends differs by account type and fund structure, and that interacts with this decision. See our companion piece on U.S. dividend withholding and check your holdings in the dividend tracker.

Bottom line

Hedged versus unhedged is not a market call. It is a question about the currency your future self will spend money in — and for most Canadians investing for a Canadian retirement over decades, the answer is less urgent than the fees, the account placement, and the withholding tax sitting alongside it.
