- Japanese investment firms have large holdings of domestic and foreign long-maturity bonds, which have already slumped in value due to duration risk.
- Norinchukin Bank, a Japanese investment firm, is one holder of such bonds, and the value of its bond portfolio has fallen from ¥36trn ($293bn) in March 2022 to ¥28trn in December 2022.
- Japan Post Bank, a savings bank, now holds 35% of foreign securities in its total holdings, and the Japanese government owns almost a third of the bank.
- Japanese investors sold $165bn more in foreign long-term bonds than they bought last year, the largest disposal on record.
- Rising rates have left bond issuers across huge swathes of the world paying more to borrow, and the disappearance of previously reliable buyers only adds to the pain.
