Rising Expected Returns in the Land of the Rising Sun

In the last 10-plus years, investors have grown accustomed to Japanese financial assets lagging their global counterparts. Using Asset Allocation Interactive (AAI), we can quickly compare the annualized real U.S.-dollar-denominated returns of Japanese bonds and stocks over the trailing decade to, respectively, all Core Bonds and all Multi-Country, U.S., and Chinese¹ public equities. Both Japanese asset classes rank at or near the bottom relative to their peers.

Due to very low starting yields and a generally strengthening U.S. dollar, the Japan Aggregate delivered an abysmal –6.5%, about 3% worse than the next-lowest performer in fixed income. As for the perhaps more salient asset class, Japanese stocks generated a respectable 4.7%, in line with the long-run historical average of most equity markets, but still third worst out of 13 major markets and far below the leader, the S&P 500, which gained 11.3% per annum over the same period during an exceptional global bull market.

As of December 2025, however, AAI’s 10-year expected returns, inclusive of valuation, have identified an interesting theme, one that runs completely counter to the last decade’s trend. Compared to the same set of assets, Japanese bonds and stocks are now expected to deliver the highest real USD returns. With bonds in blue and equities in red, Exhibit 1 shows Japanese assets currently have the highest capital market expectations (CMEs) in their respective asset classes.

What explains the disparity between the trailing and expected returns? First, a very inexpensive Japanese yen is driving both stock and bond forecasts. Indeed, based on real exchange rate (RER) data going back to 1989, the yen has rarely been cheaper relative to the dollar. This cheapness alone is predicted to add approximately 2.6% to Japanese bond and stock returns.
