The Bank of Japan's benchmark interest rate rose to a 30-year high of 0.75%. The January meeting is expected to remain unchanged, but the weakness of the yen has become a key variable. Sanae's plans for an early election triggered volatility in the high market, and the yen fell to an 18-month low. The transmission effect of inflation has strengthened, and some officials advocate raising interest rates ahead of schedule in the summer. The market predicts that interest rates may rise to 1% in September, and the terminal interest rate is expected to be 1.5%. The central bank needs to balance assessing the effects of policies with responding to political fluctuations.
