Summary
Japan’s ultra-long-term interest rates have entered the ‘3% era,’ with 30-year bond yields reaching their highest level since 1999. This surge stems from inflation, reduced demand from traditional buyers, and the Bank of Japan’s slower bond purchases. The yen’s depreciation, driven by the Japan-U.S. interest rate gap, has further complicated economic conditions, raising import costs and domestic inflation. Fiscal challenges are mounting, with bond costs reaching record highs and interest payments projected to rise significantly. To address these issues, the government is focusing on balancing economic growth and fiscal reform through wage and price improvements. However, yen depreciation and rising energy costs threaten household incomes, potentially derailing these efforts. Experts highlight the need for productivity and real wage growth to stabilize the economy and achieve fiscal sustainability.
