TL;DR
The group of Japan bases of Switzerland’s UBS Group AG (G-SIB Bucket 1, one of the world’s largest private banks). In 2023-06 , the Swiss-government-led emergency acquisition of the former Credit Suisse was completed, and as of 2024 年 the integration with the former CS Japan bases is in progress ★. In Japan it operates a 4 -pillar structure: UBS Securities (corporate IB) + UBS SuMi TRUST Wealth Management (a JV with sumitomo-mitsui-trust) + UBS Bank Tokyo Branch + UBS Asset Management. Its PB (private banking) is world-class, and in Japan it deploys wealth management for the affluent through the SuMi TRUST JV.

Global strategy
- Asia-Pacific bases: the 3 major hubs of Hong Kong / Singapore / Tokyo, ranking alongside HSBC PB / Julius Baer / Credit Suisse (pre-integration) in Asian PB competition
- Effect of the former CS integration: a two-stage approach of scale expansion vs the wind-down of risk assets (the separation of the Non-core and Legacy segment)
Japan strategy
- PB: reaching the Japanese affluent through the sumitomo-mitsui-trust JV. A combination of Sumitomo Mitsui Trust’s customer base + UBS’s global PB platform
- IB: expanding Japan IB scale through the integration with the former CS → competing with Japanese-affiliated players (smfg SMBC Nikko / mufg MUMSS) / U.S.-affiliated players (Morgan Stanley / Goldman Sachs / JPMorgan)
- Cost cutting / restructuring: by eliminating overlaps with the former CS Japan bases (departments / personnel / sales offices), making phased downsizing adjustments over 2024–2026
Alliance / acquisition strategy
- Emergency acquisition of Credit Suisse (2023-06) ★: a rescue scheme led by the Swiss government, SNB, and FINMA. The write-down of AT1 bonds caused controversy in the market
- sumitomo-mitsui-trust PB JV (2014–): joint deployment of Japan PB, mutually complementary
- Integration of the former CS Japan bases (2024): UBS Securities + former CS Securities, with the integration of Tokyo bases / personnel / operations
5. Regulation / policy
- Home-country supervision: FINMA (the Swiss Financial Market Supervisory Authority) + SNB (the Swiss National Bank)
- Japan supervision: the Financial Services Agency (FSA), the Kanto Local Finance Bureau (registration of foreign-affiliated securities companies / bank branches)
- Recent policy issues:
- 2023– litigation / international arbitration over the write-down of the former CS AT1 bonds
- 2024– debate on strengthening Swiss TBTF (Too Big To Fail) regulation (UBS alone has a prominent ratio of bank assets to GDP)
- 2024–2026 cost cutting / restructuring of the Japan bases accompanying the former CS integration in progress

The shareholding ratio of UBS SuMi TRUST WM (51% / 49%) is an estimate based on public reporting, and the latest figures should be checked against both companies’ press releases. The progress of the former CS integration and the headcount scale are in flux, and UBS IR should be checked each quarter.
