Japan's Long Bond Yields Hit Records as Market Reprices What the Central Bank Suppressed

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