TLDR
South Korea's biggest banks and securities firms are buying into local crypto exchanges and infrastructure as they jockey to control the country's future digital asset rails.
- Hana, Samsung, Hanwha and Mirae are buying large stakes in exchanges like Upbit, Korbit and Coinone, turning trading venues into strategic bank assets.
- The goal is to own the rails for stablecoins, tokenized securities, custody and payments, which could mean more compliant but more tightly controlled crypto access.
- Key swing factors are South Korea's Digital Asset Basic Act, stablecoin rules and whether bank led consortia or tech platforms end up owning most of the distribution.
Deep Dive
1. Who Is Buying What
Recent deals show a clear land grab. Hana Bank plans to acquire a 6.55 percent stake in Dunamu, the operator of Upbit, for about 1 trillion won (roughly 670 million dollars), while three Samsung affiliates are buying a combined 4 percent for about 408 million dollars, shifting nearly 14 percent of Dunamu into major financial groups in under two weeks.
Mirae Asset Consulting agreed to buy 92.06 percent of Korbit, effectively taking control of that exchange, and OKX Ventures plus Korea Investment & Securities are together taking 39.2 percent of Coinone, subject to regulatory approval. These moves, mapped in a Tiger Research based overview of 150 institutions and 196 partnerships, show banks, brokerages and card firms treating exchanges as pre licensing positions and customer gateways rather than speculative bets.
Korean crypto venues are increasingly owned by traditional finance, so future listings, fees and risk controls will be shaped by banks and securities houses, not only by crypto native founders.
2. Why Banks Want The Rails
Reports describe a multipolar contest to control four main layers: won pegged stablecoins and tokenized deposits, security token offering platforms, institutional custody and exchange front ends that aggregate users and data. A detailed industry survey highlights banks and fintechs racing to secure distribution rails and customer touchpoints that will define market share once rules are finalized.
Hana, Samsung and others explicitly link their Dunamu stakes to plans for KRW stablecoins, blockchain remittances on Dunamu's GIWA Chain, and security token issuance platforms, while KB Kookmin, Shinhan and NHN KCP run pilots with Solana and Avalanche for tokenized deposit and stablecoin payments. Owning the rails lets them bundle regulated crypto with existing banking, card and wealth products.
3. Regulation And Outcomes To Watch
Two regulatory pillars will decide how much control banks ultimately have. The Virtual Asset User Protection Act, effective since 2024, already tightened anti money laundering and transaction monitoring for exchanges, making licensed venues naturally attractive to banks.
The still evolving Digital Asset Basic Act, including ideas like a Bank of Korea backed majority ownership rule for some stablecoin issuers, will determine whether bank consortia or big tech and fintech platforms can dominate issuance and settlement. Delays to this act mean banks are positioning early through equity and alliance deals, but final market structure is not locked in.
Conclusion
Korean banks and securities firms are not chasing short term crypto trading, they are quietly buying and building the licensed pipes that will carry future stablecoin, tokenized security and payment flows. For crypto users, that likely means better integrated, more compliant fiat on and off ramps into Korean markets, but also more bank style gatekeeping over which assets and use cases can ride those rails.
