According to a report by Jin Shi Data, Bank of Japan policy board member Asahi Noguchi stated that the central bank should only intervene and increase purchases when there is a "serious disruption" in the bond market. This indicates that the Bank of Japan does not see the need to stop the recent significant rise in super long-term bond yields.
Noguchi also pointed out that the central bank must act cautiously when raising interest rates to ensure that underlying inflation remains stable around its 2% target, supported by sustained wage growth.
