The Nikkei 225 rose 1.8% to 66,167.25 as investors cheered global AI trends after a three-day holiday. While semiconductor shares drove the gains, the broader market remains cautious due to a 3.055% yield on 10-year bonds and the Bank of Japan's 1.25% policy rate, which may increase borrowing costs.
Tokyo stocks saw a strong return after a three-day holiday, with the Nikkei 225 index rising 1.8% to close at 66,167.25. The rebound was largely driven by heavy buying in semiconductor and AI-related hardware companies, as investors matched domestic prices with global technology trends that occurred while the local market was closed.
While the Nikkei showed strong gains, the broader Topix index rose only 0.2%. This performance gap highlights a split market where technology stocks are leading, but sectors like banking and services are struggling to gain momentum. Companies such as Ibiden Co. and Socionext Inc. stood out as top performers, benefiting from the global demand for advanced chip packaging hardware.
Despite the positive mood in the technology space, investors are focusing on macroeconomic pressures. Japan’s 10-year government bond yield climbed eight basis points to reach 3.055%. In financial markets, rising bond yields can make borrowing more expensive and often lower the attractiveness of stocks by offering higher returns in safer debt instruments.
The Bank of Japan’s recent policy shift, which set the interest rate at 1.25%, has created a complex environment for domestic companies. The higher rate adds to the cost of capital, which could impact profit margins if the economy slows. Additionally, the Japanese Yen continues to trade near 158 against the US dollar. Currency instability further complicates the outlook, especially for exporters, and puts pressure on financial institutions that rely on stable interest rate spreads for their earnings.
For investors, the key monitorable will be the tension between the tech-led growth narrative and these rising interest rate costs. While technology companies are currently attracting capital, the sustainability of this rally will depend on how the market handles the higher borrowing environment and whether the central bank’s tighter policy continues to influence domestic industrial growth.
