Can a weakening yen (JPY) continue to bolster Japanese equity markets? If historical relationships remain intact, the answer may be yes.

The JPY has steadily depreciated against the dollar (USD) this year, losing more than 15% as the worst performing G10 currency.

This isn’t unprecedented, however, considering the headwinds driving the yen lower versus the greenback. The U.S., much like the rest of the global economy, is wrestling with the highest inflation in four decades, rapidly forcing the Federal Reserve into monetary tightening. Speculation about where the rate hike cycle may ultimately conclude over the next 12-24 months is driving the USD higher. Despite some of the highest readings in inflation in the last decade, the Bank of Japan (BoJ) has remained committed to its accommodative policies of negative short-term interest rates and yield curve control. As a result of ever-widening interest rate differentials between the U.S. and Japan, the JPY has weakened dramatically.

Implications for Japanese Equities

The JPY has historically been negatively correlated with Japanese equity markets, owing to the orientation of Japan’s economy toward exporters. Among G10 currencies, it’s also the most negatively correlated to its domestic equity market over the long term, even surpassing the USD on a rolling 10-year basis. Although correlations have increased over the last several months, they remain firmly in negative territory on a rolling 60-month basis.

A weaker JPY in this rate environment also encourages currency hedging. With higher interest rates in the U.S., JPY investors derive positive carry by taking currency risk out of their Japanese investments. As the yen weakens further, even more carry is derived.

Conclusion: a weakening JPY has yielded higher Japanese equity prices over the long term and may even help diversify U.S. equity risk. Currency hedging may also improve returns via interest rate differentials.

What’s driving this relationship? When analyzing where Japanese companies derive their revenue, we note that only six of eleven sectors in the MSCI Japan Index derive more than 50% of their revenue from the domestic market. Contrast this with China and India, long considered among the world’s foremost exporters, and we see that both countries are even more dependent on their domestic consumers.
