Japan Bond Yields Near Multi-Decade Highs Amid Inflation Concerns

Japanese government bond yields remained near multi-decade highs on Tuesday as concerns about inflation persisted. The benchmark 10-year JGB yield rose 0.5 basis points to 3.090%, staying close to the 30-year high of 3.115% touched last week.

The strong auction of super-long-term debt offered limited relief, but investors remain cautious due to expectations of further monetary tightening by the Bank of Japan. Market participants are increasingly pricing in the possibility of another rate hike by the end of the year.

The Ministry of Finance sold around 300 billion yen ($1.91 billion) of 40-year JGBs on Tuesday, with a bid-to-cover ratio rising to 3.1 from 2.82 at the previous auction in July. This marked the highest level since July 2020.
