└── Common Functions for Regional Banks (DX, Operating Products, Cryptocurrency, Securities Resources)2020 Strategic Intent of Integration Platform Model
SBI HD had been making individual investments in regional banks since the late 2010 年, but after Yoshitaka Kitao (2020 ) proposed the “Third Megabank Concept 4 “, it converted the previously dormant existing entity (established on 2015-08-25 as ER6 Inc. and renamed to “SBI Bank Holdings” in 2019-07 ) by changing its corporate name to “SBI Regional Bank Holdings” on 2020-05-01, converting it into an integrated platform. A system that complements system investments, operating product development, and digital finance for young people—areas difficult for individual regional banks—with group resources from the SBI side. •

Significance of Former Shinsei Bank TOB
- Former Shinsei Bank had the long-standing issue of processing government-held shares (Deposit Insurance Corporation and Resolution and Collection Corporation held approximately 22%)
- SBI HD acquired former Shinsei Bank shares from 2019 , conducted TOB on 2021-09 → achieved complete subsidiary status on 2023-09 , acquiring the commercial banking core. Subsequently, it repaid public funds and relisted on 2025-12 .
“Loose Alliance” Model
- Maintaining Operational Autonomy: Operational decisions of partner regional banks are left to each bank (merger and integration are not forced)
- Resource Sharing: SBI Securities, cryptocurrency, operating products, systems, and human resources are made into common infrastructure
- Vertical Integration Not Required: Rather than complete subsidiary status like 3 megabanks, a loose alliance of capital partnership + business cooperation
- Economies of Scale: Jointly bearing DX investment difficult for individual regional banks
Competition and Competitive Axes
| Competitor | Positioning |
|---|---|
| TSUBASA Alliance | Regional bank coordination with chiba-bank and others participating. Separate organization from ndfg, a telecom-based financial holding company |
| fukuoka-fg | Kyushu-based regional bank integration precedent (former Shinwa Bank and Juhachi Bank merger) |
| concordia-fg | Former regional bank integration FG of Yokohama Bank and Higashi-Nihon Bank |
| 3 Megabanks (mufg / smfg / mizuho-fg) | Domestic major corporations focus; regional bank area outside competition scope |
Core Functions and Objectives
- Retail Digital Finance: SBI Securities, SBI Shinsei Bank, SBI Insurance and other SBI group infrastructure to regional bank customers. Shinkin SBI Net Bank was transferred to NTT DoCoMo on 2025-10
- Corporate: Utilize former Shinsei Bank’s corporate lending and specialty finance functions to regional bank corporate customers
- Asset Management: Deploy SBI Asset products and cryptocurrency (SBI VC Trade) through regional bank windows
- DX: Common accounting system standardization and unified mobile banking to reduce regional bank costs
Commercial Banking Core = SBI Shinsei Bank
- Utilize former Shinsei Bank as a “central bank for regional bank HD” sbi-shinsei-bank
- Open functions such as APLUS (credit cards), Showa Lease, and Shinsei Financial (consumer finance) to regional bank networks
5. Regulation and Policy
- Supervisory Authority: Financial Services Agency (FSA) ── Aligned with regional financial institution reorganization policy
- FSA Regional Bank Reorganization Policy: Consistent with promotion policy for “Regional Bank Reorganization for Regional Economic Revitalization”
- Public Funds Issue: Among public funds injected into former Shinsei Bank (former Japan Long-Term Credit Bank), the unrecovered portion of approximately 3500 億円 was a long-standing issue (widely mentioned in news reports). Following SBI HD subsidiary status, repayment became a point of discussion, but based on the confirmed repayment scheme agreement on 2025-06 , the remaining amount of approximately 2300 億円 was fully repaid on 2025-07-31 (based on FSA and SBI HD announcements)
