SBI Holdings signs ¥46.7B deal to take full control of Bitbank
The acquisition is targeted to close around October and is contingent on regulatory clearance.
SBI Holdings signed agreements to acquire 100% indirect ownership of Japanese crypto exchange Bitbank in a ¥46.7 billion ($289 million) transaction. SBI is positioning the buyout as a scale play that, combined with SBI VC Trade, would create Japan’s largest exchange footprint by assets under custody, pending regulatory approval.
Key Takeaways
- SBI Holdings agreed to acquire full control of Bitbank for ¥46.7 billion ($289 million), advancing a framework it first disclosed in May.
- The transaction is guided to close around October and is explicitly subject to regulatory clearance.
- SBI’s wholly owned subsidiary SBICAH will use a mix of share purchases, a third-party share allotment, and issuer buybacks to reach 100% indirect ownership.
- SBI estimates the combined Bitbank and SBI VC Trade footprint at about ¥1.1 trillion in assets under custody and roughly 2.92 million crypto accounts as of end-April.
SBI’s ¥46.7B Path to 100% Control of Bitbank
SBI Holdings has signed agreements to acquire full control of Bitbank in a ¥46.7 billion ($289 million) transaction, moving beyond a deal framework the firm first disclosed in May. The company’s stated end state is 100% indirect ownership, effectively pulling Bitbank fully inside the SBI group rather than operating it as a minority-controlled affiliate.
The key constraint is timing, not intent. SBI’s own guidance is that closing is targeted “around October,” and the company has made regulatory clearance an explicit condition. For traders, that frames the execution risk as a calendar and approvals problem, not a financing mystery.
How the Share Transfers and Buybacks Get SBI to Full Ownership
SBI laid out a multi-step structure routed through SBICAH, a wholly owned SBI subsidiary. SBICAH will first acquire shares from Bitbank CEO Noriyuki Hirosue and other shareholders.
After those purchases, SBICAH will subscribe to a third-party share allotment. A third-party share allotment is a direct issuance of new shares to a specific investor, typically used to bring in capital or a strategic owner without a public offering process.
The final cleanup step is on Bitbank’s side. Bitbank will buy back shares held by MIXI and Ceres, leaving SBI with 100% indirect ownership once the sequence is completed.
Japan Exchange Consolidation: Scale Metrics and Bitbank’s JPY-Pair Volume Mix
SBI is selling this as market-structure consolidation. The company said combining Bitbank with SBI VC Trade would total about ¥1.1 trillion in assets under custody (AUC) and roughly 2.92 million crypto accounts, based on figures from the end of April. AUC is the value of customer assets held by an exchange or custodian on behalf of users, and it is one of the cleaner measures of distribution power in a regulated market.
Bitbank’s recent trading profile suggests the acquisition is less about buying a high-velocity venue and more about adding regulated footprint and yen-denominated flow. CoinGecko data shows Bitbank’s daily trading volume has hovered below $50 million for most of the last four months, with activity concentrated in BTC/JPY (39.5% of volume) and XRP/JPY and ETH/JPY (19.7% each).
Regulatory Gates and Timeline Markers Traders Should Track Into October
The first gating item is regulatory clearance ahead of SBI’s “around October” closing window. Any slippage here matters because the deal’s strategic value is tied to consolidating custody and accounts under one umbrella, not just owning an additional brand.
Traders should also watch for an updated integration plan for combining Bitbank with SBI VC Trade, including whether SBI reiterates the ¥1.1 trillion AUC and ~2.92 million accounts figures or revises them as the process advances.
On the rails side, SBI has tied stablecoin distribution to regulatory and operational constraints. The yen-pegged stablecoin JPYSC, issued by SBI Shinsei Trust Bank and distributed by SBI VC Trade, is initially limited to transfers within SBI VC Trade accounts. SBI has said public blockchain circulation will come only after “outstanding legal and tax conditions” are resolved, with no date attached.
RLUSD, the dollar-backed stablecoin launched in Japan through SBI VC Trade with Ripple and SBI Group, is already approved under Japan’s framework for foreign-issued stablecoins and is available to institutional and retail customers. Further distribution updates there will signal whether SBI is building a broader stablecoin channel or simply adding another product line.
What This Consolidation Could Change for JPY Liquidity and Onchain Rails
I read this as a distribution and custody consolidation move first, and a spot-volume acquisition second. Bitbank’s sub-$50 million daily volume profile and heavy BTC/JPY, XRP/JPY, and ETH/JPY concentration looks like a regulated JPY flow wedge, not a bid to instantly dominate price discovery.
The threshold that matters is regulatory clearance on the October path, because the second-order effect is whether SBI can turn ¥1.1 trillion in AUC and ~2.92 million accounts into a larger stablecoin funnel for JPYSC and RLUSD once constraints ease. If that clearance holds and SBI can move JPYSC beyond internal transfers, the setup starts to look structural rather than narrative-driven, with tighter control over where JPY liquidity and onchain settlement rails get distributed in Japan.
