Mizuho Markets Cayman notes gain Fitch F1 rating under Mizuho Bank guarantee
Mizuho Markets Cayman LP has secured an F1 short-term rating from Fitch for USD150 million of senior guaranteed notes due in October 2027. The rating reflects the notes' backing from Japan-based Mizuho Bank under a broader USD10 billion medium-term note programme.
Highlights
- Mizuho Markets Cayman LP's notes received a Fitch F1 rating, backed by an unconditional guarantee from Mizuho Bank and issued under a USD10 billion programme.
- Any adjustment to Mizuho Bank's Short-Term Issuer Default Rating will directly impact the rating of the guaranteed notes, according to Fitch Ratings.
- The notes reflect ongoing trends where strong parental support and explicit guarantees influence funding conditions for cross-border bank note programmes.
Guaranteed note structure and rating basis
As reported by Fitch Ratings, the notes are issued under a USD10 billion medium-term note programme and are guaranteed by Mizuho Bank, Ltd., which is rated A/Stable/F1. The base offering memorandum for the programme is dated 31 August 2026, and Fitch says the notes will represent direct, unconditional and unsubordinated obligations of Mizuho Markets Cayman LP and, through the guarantee, of Mizuho Bank.Fitch says the F1 rating is aligned with Mizuho Bank's Short-Term Issuer Default Rating because repayment of principal, interest and other amounts due is unconditionally and irrevocably guaranteed by the bank. The agency adds that any negative or positive rating action on Mizuho Bank's Short-Term IDR will lead to similar action on the guaranteed notes.
Mizuho group links and market context
Mizuho Markets Cayman LP is a wholly owned subsidiary of Mizuho Americas LLC, a U.S. bank holding company that is wholly owned by Mizuho Bank. Mizuho Bank is described as a core operating banking arm of Mizuho Financial Group, Inc., which carries ratings of A-/Stable/F1.Fitch also notes that Mizuho Bank's total assets and total liabilities exclude acceptances and guarantees under Japan's generally accepted accounting principles balance sheet to make them globally comparable. The rating action underscores how parental support and guarantee structures continue to shape funding conditions in cross-border bank note programmes.
Our earlier coverage of Hainan Rubber’s proposed subordinated perpetual sustainable securities explained why Fitch placed the notes two notches below the issuer rating, citing their subordinated ranking and the issuer’s ability to defer coupons. We also outlined the parent-subsidiary linkage and support rationale tied to Hainan State Farms, alongside the company’s leverage and liquidity profile that frames its refinancing plans.
