State Street Corporation has announced it will acquire Mizuho Financial Group's global custody and related businesses outside Japan, enhancing its footprint in key markets and supporting cross-border investments.
State Street Corporation and Mizuho Financial Group, Inc. have announced an agreement for State Street to acquire Mizuho’s global custody and related businesses outside Japan. The transaction, initially announced earlier this year, is expected to be completed by Q4 2025, pending regulatory approvals and other closing conditions. These businesses support the overseas investments of Mizuho’s Japanese clients and operate through local subsidiaries, including Mizuho Trust & Banking (Luxembourg) S.A. and Mizuho Bank (USA). Collectively, these entities oversee approximately $580 billion in assets under custody and $24 billion in assets under administration.
The planned transfer aims to leverage State Street’s extensive global scale and servicing capabilities to benefit Mizuho’s clients. Joerg Ambrosius, President of Investment Services at State Street, highlighted the close collaboration during the transition process to ensure a seamless experience for clients and emphasized that the deal underlines State Street’s ongoing commitment to both Japan and Luxembourg, supporting its growth ambitions in these key markets.
From Mizuho’s perspective, this partnership will enable its clients to continue benefiting from State Street’s robust global infrastructure, while Mizuho retains responsibility for trust and custody services for domestic assets within Japan. Tsutomu Yamamoto, senior managing executive officer at Mizuho, expressed confidence that the combined capabilities will support Japanese clients’ offshore investment activities effectively.
State Street has maintained a presence in Japan for over 35 years, employing more than 500 personnel across Tokyo and Fukuoka, providing services such as trust, global custody, middle/back-office outsourcing, data management, trading, and financing solutions. The firm has also operated in Luxembourg for 35 years, offering fund administration, custody, and transfer agency services. This longstanding experience positions State Street well to integrate the acquired operations.
This deal reflects a broader industry trend where custodians seek to expand scale and service offerings through such strategic acquisitions, underpinning the importance of regional expertise and global infrastructure in supporting cross-border investments.
