Japan 10-Year Government Bond Yield Climbs to Highest Since 1997

Japan’s bond market remains under pressure as the 10-year yield rose 2 basis points to 2.54%, while the 30-year yield climbed to 3.760%, signaling firmer long-term borrowing conditions.

Fact Check
All key elements of the claim are strongly supported by multiple independent sources. The 10-year JGB yield reaching 2.54% as the highest since 1997 is confirmed by Trading Economics ('Japan 10Y Bond Yield Hits Near 29-year High'), the Nikkei (which reports an even higher intraday print of 2.58% on May 13), and the Japan Bond Trading Co. historical data showing a May 2026 10-year range up to 2.545%. The 30-year yield of 3.760% is confirmed by the Binance Square report and falls within the Japan Bond Trading Co.'s reported May 2026 30-year range of 3.350-3.815%. The +2 basis point move for the 10-year is consistent with the day-over-day trajectory described in Trading Economics. The only minor nuance is that the Nikkei reports a slightly higher intraday peak of 2.58% on May 13, suggesting the 2.54% figure likely reflects an earlier point in the trading session or the prior day's close, but this does not contradict the claim.
Summary

Japan’s government bond yields continued rising, with the benchmark 10-year yield increasing 2 basis points to 2.54%, its highest level since June 1997, and the 30-year yield climbing to 3.760%, according to Jin10 as reported by Odaily. The moves point to higher borrowing costs and sustained pressure across Japan’s sovereign debt market. Government bond yields are closely watched because they reflect investor expectations for inflation, interest rates, funding conditions, and fiscal outlook, while also influencing broader global risk appetite and liquidity conditions that can affect digital asset demand.
