Currency Risk and Hedged Share Classes: What You Are Actually Hedging

Reviewed by NorwegianSpark Editorial — written with AI assistance and reviewed by the NorwegianSpark SA editorial team · Last updated: August 2026

Capital at risk. Currency movements can increase or decrease your returns, and hedging removes the gains as reliably as it removes the losses. Hedging is not a safety feature. Nothing here is advice.

An investor holding a global equity fund priced in dollars, from a euro bank account, asks a reasonable question: am I exposed to the dollar?

The answer is almost always no — not to the dollar as such — and the confusion behind the question is one of the most persistent in international investing. There are three separate currencies in play, and the one printed on the fund's ticker is the one that matters least.

The three currencies

The currency the fund is priced in. The unit its share price is quoted in. It affects the conversion your broker performs when you trade, and nothing else. A global fund quoted in dollars and the identical fund quoted in euros give you the same exposure to the same companies.

The currencies of the underlying assets. This is the real exposure. A global equity fund holds American, Japanese, European and other companies, whose shares are priced and whose earnings are earned in their own currencies. That mix is your currency exposure, and it does not change when the quoting currency does.

The currency you actually spend. The one your rent, groceries and retirement are denominated in. This is the only benchmark that means anything, because the point of the portfolio is buying things where you live.

Currency risk is the gap between the second and the third. If the currencies your assets earn in weaken against the currency you spend, your portfolio buys less at home — even if it rose in its own terms. The quoting currency is bookkeeping.

What a hedged share class actually does

A hedged share class holds the same assets, then adds a currency overlay designed to strip out the effect of exchange-rate movements between the assets' currencies and the share class's currency.

Mechanically this is done with forward contracts: agreements to exchange currency at a set rate on a future date, rolled forward regularly as they expire. The fund is not buying insurance against a fall. It is locking in a rate, which cancels the movement in both directions.

Three consequences follow that the marketing language does not emphasise.

The hedge costs money, and the cost is not the fee. The price of a currency forward is set by the interest rate difference between the two currencies. Hedging into a currency with lower interest rates than the one you are hedging from generally costs you the difference, continuously — and that difference can dwarf the fund's management fee. It moves when central banks move, so it is not a fixed, quotable number.

Hedging removes the upside. If the currencies your assets earn in strengthen against yours, an unhedged holding gains and the hedged one does not. People who hedge after a period of currency losses are frequently locking in the bad outcome at the worst moment.

The hedge is approximate. It is rebalanced periodically against a value that changes daily, so it is never exact, and the residual is another small source of tracking difference — see what a fund actually costs you.

Where the evidence points: bonds yes, equities arguable

The distinction that matters is what proportion of an asset's return currency movement can swamp.

For international bonds, hedging is the mainstream position. The whole reason to hold high-quality bonds is low volatility — stability, a predictable stream, ballast against equity falls. Unhedged foreign currency exposure is materially more volatile than the bonds themselves, so an unhedged foreign bond fund can deliver equity-like swings while paying bond-like returns. That defeats the purpose of holding them. This is why hedged share classes are the default for international bond funds, and why our bond ladder strategy treats currency as a separate decision from credit.

For international equities, it is genuinely debated. Equities are volatile enough that currency movement is a smaller proportion of the total, and over long periods currency effects have tended to be less dominant than the equity returns themselves. There is also a partial natural hedge: large multinationals earn revenue across many currencies regardless of where their shares are listed. Reasonable investors land on both sides, and the cost of hedging is a real argument against.

One case is clear-cut. Money you will spend in a specific currency on a specific near-term date should not be sitting in another currency at all. That is not a hedging decision; it is a matter of not taking the risk. Our yield ladder for money you need within 12 months covers where short-horizon money belongs.

How to check what you hold

The decision, made properly

The useful test is not a forecast. Nobody, including the people who run currency desks for a living, reliably predicts exchange rates, and choosing a share class because you think a currency is cheap is a trade, not an allocation.

The test is: what currency will I spend this money in, and when?

Money to be spent soon, in a known currency, should be held in that currency. Money for decades away, invested in global equities, has decades for currency effects to average out and the cost of hedging to accumulate. Bonds held for stability should generally be hedged to your spending currency, because instability is precisely what you were trying to avoid.

Whatever you decide, decide once and leave it. Switching between hedged and unhedged based on recent currency movements is the reliable way to capture every cost of both, and the benefit of neither.
