Just Like That, Japan Is Rallying Again

It was a wild summer. In the span of a few days in late July, the market got live to two contrasting theories at once: that U.S. inflation is collapsing while Japanese inflation will remain stubbornly high. Hang around the markets long enough and you’ll see everything.

The market violently repriced interest rate differentials between the two countries, reversing the so-called yen carry trade.

The trade is characterized by borrowing in low-yielding yen to invest in stocks, overseas currencies, real estate, whatever your heart desires. As the low-yielding yen became not-so-low-yielding, positions were unwound, sending investors into a situation where they had to rapidly dump their speculative positions, many of which were Tokyo-listed stocks.

At the August lows, the Nikkei 225 changed hands for 32,077, down from an intraday high of 42,426 a few weeks prior.

We said at the time—and continue to say—that the action appeared unwarranted. Part of the unwind in the yen carry trade was the Bank of Japan’s (BoJ) rate hike, which took overnight money from 0.10% to “around 0.25%.” Our reaction? We were surprised that the market was surprised; the central bank had been telegraphing a rate increase for months.

Since then, things have settled down. Investors have come to realize that there will still be a yawning gap between the two nations’ cost of money even if the Fed Funds Rate gets the chainsaw. The Nikkei is back up to 37,723.
