Siam Commercial, Thailand's largest bank in which its king is the largest shareholder, acquires 51% of crypto exchange Bitkub for $535M, at a $1B+ valuation
- Siam Commercial Bank buys majority stake in Bitkub Online — Bitkub coin surges 200% to record $2.85 following Siam deal
Context & Ripple Effects
Siam Commercial Bank's $535M purchase of a controlling 51% stake in Bitkub caps a fast-moving quarter for Thai banking money in crypto: just two months earlier, rival Krungsri's VC arm joined Zipmex's $41M Series B, making an exchange bet the region's banks' preferred entry point. The premium is striking — a valuation above $1B for a local exchange — and the market read it instantly, with Bitkub's own coin surging roughly 200% to a record $2.85 on the news.
What makes this deal worth tracking is how it resolves: SCB ultimately walks away in 2022, citing unresolved regulatory issues at Bitkub, while Kasikorn takes the consolidation route instead with its 97% buyout of Satang at a fraction of the price. The arc from headline premium to regulatory walk-away is the real story.
First-order effects
- Bitkub gains a majority owner with royal-linked capital and banking credibility, while SCB acquires control of Thailand's leading crypto exchange at a $1B+ valuation rather than building one.
- Bitkub token holders capture an immediate windfall — the coin's ~200% surge to $2.85 shows the deal repriced the exchange's entire ecosystem overnight.
Second-order effects
- Kasikorn Bank answers with its own exchange acquisition, buying Satang for ~$102.8M — a far cheaper entry that implicitly questions whether SCB's $1B+ price was necessary.
- Regional peers copy the bank-buys-exchange template: Japan's SBI agrees to acquire Bitbank for ~$289M, and Korea's Hana Bank pays $672.5M for a minority stake in Upbit operator Dunamu.
Third-order effects
- Regulatory standing, not user base, becomes the binding constraint on bank-crypto M&A: SCB's abandonment of the deal over Bitkub's regulatory issues shows diligence failures can unwind even signed billion-dollar premiums.
- If the pattern holds, Southeast Asia's crypto market consolidates under traditional banking groups — with exchanges valued as licensed distribution channels, and unlicensed operators facing the kind of enforcement Thailand applied when it blocked and charged Bybit, OKX, and other offshore platforms.
The trend: Asian retail banks are choosing to acquire established crypto exchanges outright as their digital-asset entry strategy, but regulatory cleanliness is proving to be the deal-breaker that separates completed deals from abandoned ones.
