Mizuho Financial Group is issuing ¥180.5bn of subordinated bonds in two 10-year tranches, turning its latest shelf supplement into a concrete capital-markets trade rather than routine disclosure. The deal comprises a ¥73.5bn 34th series and a ¥107bn 35th series with an early-redemption clause. Both tranches carry write-down and subordination features.
| Item | Amount | Notes |
|---|---|---|
| Current shelf size | ¥3tn | Runs until Feb. 11, 2028 |
| 34th series | ¥73.5bn | 10-year subordinated bond |
| 35th series | ¥107bn | 10-year subordinated bond with early-redemption clause |
| Earlier use of same shelf | ¥190bn | Offering filed March 6, 2026 |
| Remaining capacity after current deal | ¥2.81tn | As listed in the supplement |
One detail worth noticing is that Mizuho is not using a single template. The 34th series is a ¥73.5bn 10-year subordinated bond, while the 35th is a larger ¥107bn 10-year tranche that adds the early-redemption feature. Even without pricing in view, the split shows the bank varying the structure within one outing.
The shelf context matters almost as much as the deal itself. This is the second use of Mizuho's current ¥3tn programme, which was filed on Feb. 4, became effective on Feb. 12, and runs until Feb. 11, 2028. The supplement's historical table shows one earlier draw, a ¥190bn offering filed on March 6, and lists remaining capacity at ¥2.81tn after the new transaction. That leaves substantial room for further issuance, while making clear that the shelf is being used, not merely parked.
A separate SoftBank Group registration highlights the distinction between optionality and execution. SoftBank registered a bond shelf for up to ¥1.5tn between July 10, 2026 and July 9, 2028. Mizuho's supplement, by contrast, names the tranches and the money. For readers outside Japan, that is the practical read-through from the pair of disclosures: shelf filings show how much room an issuer wants, while supplements show when that room is actually being used.
