TL;DR
An intermediate holding company that oversees the securities / investment-banking business of Mitsubishi UFJ FG (MUFG). Its biggest differentiating factor from domestic peers is its adoption of a JV (joint venture) structure with Morgan Stanley of the US. A two-tier structure of a domestic JV: Mitsubishi UFJ Morgan Stanley Securities (MUFG 60% / Morgan Stanley 40%) + Morgan Stanley MUFG Securities (MSMS) (Morgan Stanley 51% / MUFG 49%). For overseas subsidiaries, it directly holds MUFG Securities Americas / MUFG Securities EMEA / MUFG Securities (Asia). The origin of the JV structure was MUFG’s 90 億-dollar investment in Morgan Stanley (becoming the company’s rescue capital) immediately after the Lehman shock in 2008-09 . Japan’s largest mega-bank-affiliated securities group.

Why it was split into 2 社
- MUMSS (domestic JV): Responsible for Japanese domestic retail customers / domestic wholesale business
- MUFG-led (holding 60%) = retaining the Japanese customer base under the MUFG brand
- MSMS (institutional-investor JV): Sales / trading for global institutional investors
- Morgan Stanley-led (holding 51%) = utilizing the global institutional-investor network and product-sourcing capability
- Overseas subsidiaries: Directly held by MUFG 100% → maintaining an independent overseas presence as a group
Strategic relationship with Morgan Stanley
- 2008-09 MUFG’s 90 億-dollar investment → the week after Lehman’s bankruptcy, a symbolic transaction of the global financial crisis
- The invested shares were initially preferred shares → converted to common shares → MUFG now holds over 20% of Morgan Stanley’s shares
- Dispatch of a MUFG director to Morgan Stanley’s board → strategic influence
- Cooperation on global M&A joint deals / shareholder IPO joint deals
