Bank of Japan Flags Stock Market Overheating as Nikkei Hits Record High
The Bank of Japan (BOJ) has raised concerns about potential overheating in Japan's stock market as the Nikkei index closed at a record high, surging nearly 24% this year. The BOJ's heat map now shows a 'red' indicator for stock prices, while 13 other economic categories remain 'green'. Real estate prices are rising, with new condominium prices in Tokyo increasing by 20.40% year-over-year. Despite concerns, the BOJ maintains that Japan's financial system remains stable. The central bank exited its decade-long stimulus program last year and raised short-term rates to 0.50% in January, with expectations of another rate increase in the fourth quarter.

The Bank of Japan (BOJ) has raised concerns about potential overheating in Japan's stock market as the Nikkei index closed at a record high. This development comes in the wake of Sanae Takaichi's parliamentary victory, making her Japan's first female prime minister.
Market Performance and Concerns
The Nikkei has seen a remarkable surge of nearly 24% this year, prompting the BOJ to issue a warning about the market's condition. The central bank's heat map now shows a 'red' indicator for stock prices, signaling overheating, while 13 other categories remain 'green'.
Economic Indicators
The BOJ highlighted several key economic factors:
| Indicator | Status |
|---|---|
| Stock Market | Overheating (Red) |
| Other Economic Categories | Stable (Green) |
| Real Estate Prices | Rising, especially in major metropolitan areas |
| New Condominium Prices in Tokyo | 20.40% increase (April-September, year-over-year) |
Potential Risks
The central bank identified several potential risks to financial stability:
- Uncertainty over U.S. trade policy could trigger sharp market corrections affecting financial institutions.
- Increased leverage by foreign hedge funds in Japanese government bond trading could amplify market volatility through rapid position adjustments and deleveraging.
BOJ's Stance and Monetary Policy
Despite these concerns, the BOJ maintains that Japan's financial system remains stable, with banks maintaining solid capital bases. The central bank has taken significant steps in its monetary policy:
- Exited its decade-long stimulus program last year
- Raised short-term rates to 0.50% in January
- Most economists expect another rate increase in the fourth quarter
Foreign Investment Impact
The rise in real estate prices, particularly in major metropolitan areas, has been attributed to increased foreign investment demand. This trend underscores the growing international interest in Japanese assets.
The Bank of Japan continues to monitor these developments closely, balancing the need for economic growth with the importance of maintaining financial stability in an evolving global economic landscape.
