Currency-Hedged Fund vs. Unhedged Fund: Which Exposure Are You Actually Getting?
Two international funds can hold nearly identical stocks and still produce noticeably different returns, simply because of a decision made behind the scenes about currency.
The short answer
An unhedged international fund holds foreign securities without offsetting currency risk, so the fund’s return reflects both how those securities performed and how the foreign currency moved against the US dollar. A currency-hedged fund uses financial contracts to offset that currency movement, aiming to isolate the return of the underlying securities themselves, closer to what an investor in that foreign market would experience in local currency terms.
How the unhedged version works
When a US-based fund buys stocks or bonds priced in a foreign currency, the fund’s returns are exposed to two separate factors: the performance of the underlying securities, and the exchange rate between that currency and the dollar. If the foreign currency strengthens against the dollar, that adds to the fund’s return; if it weakens, that subtracts from it, independent of how the underlying stocks actually performed. Over a longer investment horizon, currency effects can partially offset each other, but over shorter periods they can meaningfully amplify or dampen the fund’s results, sometimes overwhelming the underlying securities’ own performance entirely in a given year.
How the hedged version works
A currency-hedged fund uses contracts, typically currency forwards, to offset the currency exposure that would otherwise come from holding foreign securities. The goal is to leave the fund’s return driven primarily by the performance of the underlying holdings, without the added swings caused by exchange rate movement. That hedging isn’t free, though — it involves ongoing costs tied to the interest rate difference between the two currencies involved, and hedging is rarely perfect, so some residual currency effect can still show up in the fund’s results. Hedging contracts also need to be renewed on a regular schedule as they expire, which means the fund is continuously managing this exposure rather than setting it once and leaving it alone.
Weighing which exposure fits a given goal
An investor who wants to isolate the performance of foreign companies or bonds, without also taking on an implicit currency position, may find a hedged fund more aligned with that goal. An investor who’s comfortable with, or specifically wants, exposure to currency movement as part of their overall diversification, might prefer the unhedged version. Neither choice is inherently safer or riskier in every circumstance — it depends on what role the international holding is meant to play in the broader portfolio, how much currency exposure already exists elsewhere, and each investor’s own risk tolerance. Some investors also split the difference, holding a combination of hedged and unhedged funds so that currency exposure becomes a deliberate choice rather than an incidental byproduct of investing internationally at all.
What to weigh
The underlying securities can be identical between a hedged and unhedged version of the same fund, yet the two can produce different returns over any given period because of what’s happening with currency behind the scenes. Understanding which exposure a specific fund is actually designed to deliver is more useful than assuming “hedged” is automatically the safer or better option.
