Japan's 30-Year Bond Yield Hits Record 3.28% as Super-Long Curve Reprices

Japan's 30-year government bond yield hit an all-time high of 3.28% in mid-July 2026, Reuters reported. The 20-year reached 2.69%, its highest since 1999. The 10-year has risen over 70 basis points year-to-date to 2.69% per CNBC. The concentration in super-long maturities signals investors are repricing duration risk the Bank of Japan suppressed for years under yield-curve control.
