Hedging out the currency risk from international equities is currently en vogue after investors in the Japanese equity market dramatically enhanced their returns by hedging out the yen exposure in 2013. Market participants investing in international equities, must ask themselves: “to hedge or not to hedge?” As we shall elaborate, investors might be asking the wrong question.
When investing in international equities, the return stream generated can be broken into equity returns and currency returns. As the chart below shows, between 30% and 50% of monthly equity index returns, when measured in U.S. dollars, were attributable to currency fluctuation1:
The contribution works on the upside, as well as on the downside. In a month where the local country’s stock market moved up, it is possible a good portion of the gain may be attributed to currency appreciation. Similarly, in a down month, a good portion of the loss may be attributed to currency depreciation.
Let’s look at the correlation2 between the currency moves and these markets. For a currency-hedged international equity investment to enhance returns, one would want a rising equity market and a negative correlation between equities and the exchange rate:
For currencies with positive correlation with the local stock market (e.g., euro), hedged investors may get a buffer when European stocks go down (by avoiding the double loss from both stocks and the euro), but lose the upside when European stocks go up (in which case the euro usually goes up).
For currencies with negative correlation to the local stock market (e.g., Japanese yen), hedged investors may get higher returns when the Japanese stock market goes up (by avoiding the loss in the yen) but lose the buffer when Japanese stock market goes down (in which case the yen usually go up).
If the yen continues to have a negative relationship with the Japanese stock market and the Nikkei rises, then it might make sense to hedge out the currency risk. However, note that this trade hasn’t worked well this year with a falling Nikkei and a rising yen.
One of the reasons that investors may want to hedge the local currency exposure is because they feel they have an edge on making directional calls on broad equity markets in various countries but don’t understand the currency markets or don’t have a directional view on a given local currency. It would be frustrating to get the equity market call right and still lose money in U.S. dollar terms because of local currency fluctuation.
Rather than hedging or not hedging, investors may want to consider actively managing currency risk. Not hedging and taking a leap of faith on up to half the returns on a return stream appears imprudent to us. But conversely, eliminating the potential value that currencies may bring provide can lead investors to leave returns on the table.
What does it mean to actively hedge the currency risk? At risk of sounding self-promotional, this is what we do at Merk. We either zoom in on the currency risk, such as in our Merk Absolute Return Currency Fund (MABFX) where we trade in and out of currencies on either side of the dollar and possibly earn a modest rate on our collateral (i.e., no underlying equity exposure). In other words, the returns come primarily from the currency trading activity. In doing so, investors stay away from equity risk. But for those that have taken out the currency risk from their international equities through hedged international equity funds, we argue investors should consider managing the currency risk separately. The strategy pursued in MABFX is a “long/short” strategy, i.e., it does not have an ex-ante bias for or against the dollar. We can take a positive or negative position on any currency we invest in relative to the dollar at any time. To learn more, please download a fact sheet and read the prospectus.
In our opinion, there’s no need to eliminate the currency risk for an equity investment. In our Merk Currency Enhanced U.S. Equity Fund (MUSFX), we are adding actively managed currency risk to U.S. equities with what is called a “currency overlay”. In doing so, the Fund adds a return stream that has historically had a low correlation with traditional asset classes and aims to generate positive active returns (i.e., alpha3). The Fund has beaten both the S&P 500 Index and the MSCI EAFE (an international equity benchmark) since inception:

Investment return and principal value will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than original cost.

Below is a visualization of the equity and currency components of the Merk Currency Enhanced U.S. Equity Fund (MUSFX). It is meant merely as an illustration of the concept of a currency overlay as described above.
The reason we mention this Fund here is to show that active currency management can add value to an equity portfolio. As this isn’t the place of extensively discuss this Fund, to learn more, please download a fact sheet and read the prospectus.
To summarize: international investors may either be taking on unnecessary risk if they leave their foreign equity positions un-hedged from a currency standpoint, or they may be leaving attractive uncorrelated returns on the table by passively hedging. As a result we encourage investors to consider finding a way to actively managing currency risk.
