Currency hedging is similar to insurance, which you buy to protect yourself from an unforeseen event. It’s an attempt to reduce the effects of currency fluctuations. In order to hedge an investment, investment managers will set up a related investment designed to offset potential losses. In general, currency hedging reduces the increase or decrease in the value of an investment due to changes in the exchange rate. It’s an attempt to even out results.
Investors shouldn’t make long-term investment decisions based on expectations of future foreign currency movements. Here are three reasons why:
1. It is almost impossible to predict the timing of currency movements.
Predicting when a particular currency may rise or fall is a very difficult task and is best left to investment professionals.
Exchange rate movements tend to vary over time and can be severe over shorter time periods.
Over the short-term currencies can vary significantly

2. The impact of currency movements tends to diminish over time.
While exchange rates fluctuate from year to year, the impact of currency on investment returns declines over time.

3. In a diversified portfolio, currency movements tend to even out.
A well-diversified portfolio has exposure to many different currencies. The interplay between baskets of currencies is sometimes referred to as a natural hedge.
There are two main ways portfolio managers manage foreign currency risk :
- Forward contracts – The portfolio manager can enter into an agreement to exchange a fixed amount of currency at a future date and specified rate. The value of this contract will fluctuate and essentially offset the currency exposure in the underlying assets. Keep in mind the investment will not benefit if currency fluctuations work in its favour.
- Options – For a fee, options give the holder the right but not the obligation to exchange one currency for another at a set rate during a certain period of time. This reduces the potential that a change in exchange rates will affect the return on the investment.
Hedging removes the impact of currency volatility so that the main factor in the fund’s return is the performance of the underlying securities.
|Effects of changes in currency value:||On an unhedged US $ portfolio||On a hedged US $ portfolio||On a 50 % hedged US $ portfolio|
|C$ ↑ 10 % vs. US$||-10 %||0 %||-5 %|
|C $ ↓ 10 % vs. US $||+10 %||0 %||+5 %|
It's important for investors to consider their appetite for currency exposure prior to investing in a mutual fund with a foreign investment mandate. Remaining unhedged may be appropriate for some but not for others.
