Fitch Ratings has given Mizuho Markets Cayman's $250 million senior guaranteed notes due 2028 an A long-term rating, according to a Thursday release.
The notes are under the $10 billion medium-term note program guaranteed by Mizuho Bank, a core operating banking arm of Mizuho Financial Group (TYO:8411).
The notes' rating is equivalent to Mizuho Bank's long-term issuer default rating, since the bank unconditionally and irrevocably guarantees the repayment of principal, interest and other amounts payable, Fitch said.
Negative or positive actions on the bank's rating will prompt similar actions on the notes.
