Fitch Ratings has placed an A long-term rating on Mizuho Financial Group (TYO:8411) subsidiary Mizuho Bank's $110 million senior unsecured notes due 2030, according to a Monday release.
The bank's New York branch guarantees the $10 billion program in which the notes are issued.
The notes serve as obligations of the bank and its branch, with the former's rating aligning with the bank's long-term issuer default rating.
Changes in the bank's rating will trigger similar actions on the notes, Fitch said.
