On Tuesday, the results of Japan's first 10-year government bond auction since its recent large-scale currency intervention greatly disappointed the market. The accepted price fell by the second-highest margin this century, and the cover price plummeted to 2.56, the lowest since May 2025. Following this, the 10-year Japanese government bond yield immediately jumped 5 basis points to 2.87%, rapidly approaching its recent peak of 2.90% in July, with government bond futures simultaneously falling 34 basis points to 126.37.
Analysts believe that the weak demand in this auction reflects market dissatisfaction with the Bank of Japan (BOJ)'s failure to more clearly signal its intention to address inflationary pressures and raise interest rates faster. Furthermore, this debacle has also raised questions about the effectiveness of the Japanese authorities' previous currency intervention, which cost nearly $100 billion. The USD/JPY exchange rate has rebounded by nearly 300 basis points, erasing one-third of the intervention's effect.
Bloomberg strategists warn that if Japanese government bond yields break through last month's high, it could have a strong negative impact on US and other G10 government bonds, subsequently affecting global fixed income markets.
