equity strategies have become increasingly popular in the exchange-traded fund (ETF) investment scene, and it started with the significant weakening of the yen, which led to a wide disparity in performance between unhedged
and currency-hedged Japanese ETFs.
A key driver in the case of Japan was negative correlation
, or an inverse relationship, between the performance of Japanese stocks and the yen. As the yen weakened, Japanese stocks performed well.
There is recent evidence that Europe is becoming more Japan-like in displaying negative correlations between its equity markets and its currency moves. This negative correlation in Europe is not a new phenomenon: Much of the 1990s into the mid-2000s was characterized by a persistent negative correlation between the trade-weighted euro and the respective European stocks. The return of these stronger negative correlations is why I say the euro is increasingly the new yen.
Negative Correlations: A Historic Look Back
Over the years, the Japanese yen has become increasingly negatively correlated to equities. While beginning in the ’70s there was a run of approximately 25 years of positive correlation, 1995 marked a new regime. The new regime of negative yen and equity correlations in Japan coincided with a period of slow growth, deflation
and zero-bound policy rates by the Bank of Japan (BOJ); this negative correlation has been prevalent ever since.
In many ways, this macroeconomic backdrop is similar to that of the eurozone
; since the beginning of 2014, both the euro and local equities have started to show increasingly negative correlation. What may be surprising is how often this was the case during the ’90s—and how Europe has historically been more “Japan-like” in its negative correlation between equity markets and the European currencies.

Why Have Correlations Turned Negative and Japan-Like? Is This a Replay of the ’90s?
As the above chart shows, there was a nine-year stretch between September 1, 1992, and May 31, 2001, when European currencies in the MSCI EMU Index
(EMU) depreciated 40.2% cumulatively versus the U.S. dollar, and EMU stocks in local currency terms had one of their best stretches ever, returning 19.8% per year. On a trade-weighted basis, European currencies declined 27.9% during the same period. This period alone suggests the European markets can perform well when the euro declines.
Per the charts above, in the 1,252 rolling 52-week periods examined from January 1991 through December 2014, the Euro Stoxx 50 had a negative correlation to the European currencies, measured on a trade-weighted index, 60% of the time. The Nikkei 225 Index
had a negative correlation to the yen only 57% of the time, albeit with very highly negative correlations that began showing up in late 2007.
Below are two rationales for the euro becoming more negatively correlated:
• Quantitative Easing (QE) to Buoy Equity Markets and Simultaneously Weaken Euro:
In light of the new policy measures announced by the European Central Bank (ECB) in 2014—and the anticipation of new measures in 2015—many expect more policy action on the asset-purchase front, particularly with sovereign bond
buying, corporate bond buying and outright QE. The anticipation of more ECB action is underpinned by declining growth expectations and mounting disinflation
fears in the eurozone. This could lead to currency weakness and simultaneous risk-asset (equity) market outperformance, which can result in an even more negative correlation.
• Aggressive Policy Action to Encourage Currency-Hedging Activity:
In 2014 the ECB launched aggressive monetary policy
easing, including verbal intervention, negative deposit rates and other liquidity
infusions (targeted longer-term refinancing operations, TLTRO)
. As a result, the ECB has succeeded in guiding markets toward a weaker euro in 2014. We have already started to see an increase in asset flows to currency-hedged strategies for Europe in 2014 and expect this to continue if asset flows pick up for European investments1
The Case for Euro Hedging
Given that many of the themes discussed above are likely to play out over the course of the next few years, negative correlations in the eurozone may very well persist and become even more negative. To illustrate the point, Goldman Sachs recently downgraded its EURUSD2
forecast to 1.08 in 12 months, 1.00 (parity) by the end of 2016 and 0.90 by the end of 2017.
WisdomTree believes currency-hedged investment strategies
are growing in prominence due to shifting policy winds among global central banks. While the ECB and the BOJ have newly embarked on aggressive easing measures, the U.S. Federal Reserve is largely expected to begin raising rates in the middle of 2015. This policy dichotomy could signal potential for a stronger dollar in the months ahead. From this standpoint, I believe we are in the very early stages of flows heading toward currency-hedged strategies—especially for Europe.
