- No financial terms, completion timeline, or transferring asset volumes were disclosed.

- Institutions with tokenised or tokenisation-ready mandates at Mizuho face integration risk and potential service-scope changes once the business migrates.
State Street has entered into an agreement to acquire the global custody business of Mizuho Financial Group, according to a notice from Mizuho. No financial terms, completion timeline, or transferring asset volumes were disclosed in the brief announcement.
The transaction removes a Japan-headquartered custodian from the global market and consolidates client relationships under State Street’s infrastructure. For institutions with tokenised or tokenisation-ready mandates held at Mizuho custody, the deal introduces integration risk and a potential shift in service scope once the business migrates.
The agreement is a horizon event for any Mizuho custody relationship: transition mechanics, continuity of tokenised asset handling and digital securities support under State Street, and the acquirer’s platform fit for the forward book all need confirming before the deal closes.
