Japan's government bond market is experiencing unprecedented yield increases across multiple maturities. The yield on the 30-year Japanese Government Bond (JGB) reached a record high of 3.22%, the highest since its debut in 1999. Similarly, the 10-year JGB yield climbed to 1.625%, marking its highest level since October 2008. The 40-year bond yield also rose to 3.435%, nearing historical peaks since its introduction in 2007. These yield surges reflect persistent concerns over sticky inflation and have led to increased selling pressure, with some investors willing to offload bonds at discounts to the Bank of Japan (BoJ). In response, the BoJ announced a total JGB purchase offer of ¥885 billion across various maturities, including ¥325 billion in the 3–5 year segment, ¥350 billion in the 5–10 year segment, and ¥135 billion in the 10–25 year segment. The rising yields have raised questions about potential ripple effects on global markets, including US Treasuries and equities, and have prompted speculation about risks to the carry trade. Meanwhile, Taiwan's 10-year government bond yield dropped slightly to 1.3950%. The current dynamics underscore significant volatility and shifts in Japan's long-term debt market amid evolving economic conditions.
