Mizuho Trust & Banking (みずほ信託銀行)

Wiki route

This entry sits under trust-banks INDEX (its domain route). Read it against Mitsubishi UFJ Trust and Banking (MUTB) and Smtb for peer / contrast (the other megabank-group trust banks), and against the FSA plus banking for the supervisory / system boundary. The commercial-bank sibling in the same group is Mizuho Bank.

TL;DR

Mizuho Trust & Banking Co., Ltd. (みずほ信託銀行) is the trust-bank operating company of Mizuho FG (Mizuho FG). It is a trust-concurrent financial institution that holds, in addition to a bank license under the Banking Act, concurrent authorization for trust business under the Concurrent Operation Act, and conducts banking business together with trust, pension, real-estate, transfer-agency, and entrusted-property services as an integrated whole. The commercial-banking core is borne by Mizuho Bank, while Mizuho Trust & Banking bears the trust / entrusted-property side — a division of functions.

2. Operating model

As a trust-concurrent financial institution, Mizuho Trust & Banking bears the following:

• Personal and corporate trust solutions: trust products for individuals, such as inheritance, asset succession, and testamentary trusts, and for corporations.
• Pension trusts, transfer agency, real estate: pension trusts for defined-benefit / defined-contribution pensions, transfer-agency services as shareholder-registry administrator, real-estate trusts, and real-estate brokerage.
• Entrusted-property management and liquidation: entrusted-property management including monetary claims and electronically recorded monetary claims, and trusteeship of securitization schemes.

Together with Mizuho Bank (commercial bank), Mizuho Securities, and Asset Management One, the division of functions across banking, securities, asset management, and trust within Mizuho FG becomes visible. Supervision is borne by Financial Services Agency (FSA).
