Yields on Japanese government bonds have continued to rise across multiple maturities, reaching levels not seen in decades. The 20-year Japanese Government Bond (JGB) yield climbed to 2.66%, marking its highest point since 1999. Similarly, the 30-year JGB yield hit a fresh record high of 3.2%, tying the previous peak last observed in July 2025 and representing the highest level since 1999. The 10-year JGB yield also increased to 1.615%, its highest since October 2008. Shorter-term yields have risen as well, with the 5-year bond yield reaching 1.13%, the highest since late July 2025, and the 2-year yield rising to 0.85%. The 40-year government bond yield climbed to 3.44%. These increases reflect ongoing concerns about persistent inflation and fiscal challenges in Japan. Investors appear to be cautious, particularly toward low-coupon super-long bonds, which face the risk of a slump in the near term. The upward trend in yields underscores market sensitivity to Japan's fiscal outlook and inflation dynamics.
