Japan Post Bank (7182) put a number on its bond-portfolio drawdown on October 28: an unrealized loss of ¥5.676tn at the end of the second quarter of the year ending March 2027, which closed on September 30. The bank said the loss does not change its consolidated earnings forecast or its dividend forecast for April 1, 2026 to March 31, 2027.
What the figure covers
The scope is narrow, and the notice states it. The figure covers only bonds classified as held to maturity that are listed on a domestic financial instruments exchange. Those securities carry a book value of ¥33.17tn and a market value of ¥27.49tn. The bank reports no unrealized gains on the same group of securities, so the net unrealized loss is the same ¥5.676tn.
| Measure | Amount | Loss as share of measure |
|---|---|---|
| Unrealized loss | ¥5.676tn | n/a |
| Book value of covered securities | ¥33.17tn | n/a |
| Market value of covered securities | ¥27.49tn | n/a |
| Consolidated ordinary profit, year to March 2026 | ¥759.2bn | 747.6% |
| Net profit attributable to parent, year to March 2026 | ¥525.6bn | 1,079.9% |
Sized against last year's profit
The bank set the loss against two profit figures from the year to March 2026. Against consolidated ordinary profit of ¥759.2bn, the loss is 747.6%. Against net profit attributable to owners of the parent of ¥525.6bn, it is 1,079.9%. The notice presents these as ratios of the unrealized loss to a closed year's profit. It does not compare them with any capital measure.
What the bank says about earnings
The notice says the item has no effect on the consolidated earnings forecast or the dividend forecast for the current fiscal year. It adds that the bank will disclose promptly any matter that later needs disclosure.
What the notice leaves open
The notice does not report any sale or realized loss. It also gives no breakdown by bond type or maturity, and it states no cause for the decline in market value.
