Overview
Mizuho Americas is the Americas corporate and investment banking platform of Japan-based Mizuho Financial Group. Established on July 1, 2016 as a United States bank holding company, it coordinates a broad regional franchise serving corporations, financial institutions, institutional investors, public-sector entities, and other sophisticated market participants. Its activities combine commercial banking, investment banking, securities distribution and trading, financing, treasury services, custody, and capital-markets advisory work. The platform is organized around businesses that include corporate and investment banking, loan markets, leveraged capital markets, equity, fixed income, high-yield sales and trading, and related financing and aggregation functions. Through these activities, Mizuho supports clients with loans, deposits, real-estate finance, project finance, asset securitization, debt and equity underwriting, mergers and acquisitions advice, securities execution, derivatives and futures clearing, and access to domestic and international capital markets. Mizuho's principal United States operating entities include Mizuho Bank USA, Mizuho Securities USA LLC, and Mizuho Trust & Banking Co. (USA). Mizuho Bank USA concentrates on commercial banking and structured finance, including deposits, corporate lending, real-estate finance, asset securitization, and project financing. Mizuho Securities USA is an SEC-registered broker-dealer, a Federal Reserve Bank of New York-designated primary dealer in U.S. Treasury securities, and a Commodity Futures Trading Commission-registered futures commission merchant. Its institutional business covers equity research and execution, equity and equity-linked distribution, fixed-income products, debt capital markets, mergers and acquisitions, advisory services, futures clearing, and securities financing. Mizuho Trust & Banking Co. (USA) provides custody, master custody, securities lending, settlement, cash-management, corporate-action, proxy, and reporting services. The Americas franchise has expanded through portfolio acquisitions, personnel transfers, new product capabilities, and strategic transactions. In 2015, before the formal 2016 establishment of the holding company, Mizuho agreed to acquire a substantial U.S. and Canadian corporate-loan portfolio from Royal Bank of Scotland and hired approximately 200 related professionals. It later broadened its investment-banking and alternative-capital capabilities through the 2021 acquisition of private-equity placement agent Capstone Partners, the 2023 acquisition of part of Credit Suisse's agency securitized-products trading business, and an announced agreement to acquire investment bank Greenhill in an all-cash transaction. Mizuho Americas also participates in major capital-markets transactions. In 2020 it acted as an active bookrunner on Mizuho Financial Group's diversity and inclusion bond. In 2023, Mizuho Securities USA held a lead-underwriter role in Arm Holdings' initial public offering, one of the year's largest technology offerings. Beyond financial products, the brand has developed a public profile through sponsorship of the Mizuho Americas Open, an LPGA Tour event at Liberty National Golf Course in New Jersey, and a partnership with Girls Inc. Its overall positioning is that of a Japan-connected, globally integrated financial-services platform with deep capabilities in U.S. and cross-border corporate and institutional markets.
History
Mizuho Americas was created on July 1, 2016 as a United States bank holding company and the Americas corporate and investment-banking arm of Mizuho Financial Group, whose headquarters are in Tokyo. The platform brought together Mizuho's regional banking, securities, trust, financing, and markets businesses under a more integrated structure for serving corporate and institutional clients across the United States, Canada, and Latin America. Its expansion preceded the formal creation of the holding company. In February 2015, Mizuho agreed to acquire Royal Bank of Scotland's U.S. and Canadian corporate-loan portfolio. The transaction increased the size of Mizuho's U.S. corporate-loan book by approximately half. In April of that year, Mizuho also hired about 200 RBS employees working in fixed income, debt capital markets, debt syndication, leveraged finance, loans, and derivatives. These moves strengthened Mizuho's North American lending and markets platform and helped establish a larger base for its later Americas organization. The resulting business operates through several specialist entities. Mizuho Bank USA provides deposits, loans, real-estate finance, asset securitization, and project-finance services. Mizuho Securities USA LLC is an institutional broker-dealer with equity, fixed income, futures, clearing, execution, underwriting, advisory, and capital-markets capabilities. It is registered with the U.S. Securities and Exchange Commission, acts as a primary dealer in U.S. Treasury securities designated by the Federal Reserve Bank of New York, and is registered with the Commodity Futures Trading Commission as a futures commission merchant. Mizuho Trust & Banking Co. (USA) provides custody, master custody, securities lending, settlement, cash-management, corporate-action, proxy, and reporting services. Mizuho Americas' securities business covers U.S. Treasuries, corporate bonds, agency securities, mortgage-backed and asset-backed securities, Japanese government bonds, yen fixed income, emerging-market products, securities financing, and strategic credit activities. Its equity operation provides research, equity and equity-linked distribution, execution, capital-markets access, and corporate-access services such as non-deal roadshows. The investment-banking platform works across debt and equity underwriting, mergers and acquisitions, leveraged finance, and advisory assignments. The platform continued to broaden through acquisitions and strategic investments. In 2021, Mizuho acquired Dallas-based private-equity placement agent Capstone Partners. In January 2023, it acquired a significant part of Credit Suisse's agency securitized-products trading business. During 2023, Mizuho also announced a definitive agreement to acquire Greenhill in an all-cash transaction. These transactions reflected an effort to increase Mizuho's scale in private capital, securitized products, and financial advisory services. Mizuho Americas has participated in prominent capital-markets transactions. In 2020, it acted as an active bookrunner on Mizuho Financial Group's $2.5 billion diversity and inclusion bond. In September 2023, Mizuho Securities USA held a lead-underwriting role in Arm Holdings' initial public offering. The firm has also pursued visibility through community and sports initiatives. It became title sponsor of the Mizuho Americas Open, whose inaugural LPGA Tour tournament was held at Liberty National Golf Course in New Jersey from May 29 to June 4, 2023. The event included a junior-golf component organized with the AJGA. In the same year, Mizuho began a partnership with Girls Inc. Overall, Mizuho Americas represents Mizuho Financial Group's integrated regional proposition for financing, advisory, securities, markets, and institutional services.
