Hana Bank is buying a 6.55% stake in Dunamu, the company behind South Korea’s largest crypto exchange Upbit, in a deal worth about 1 trillion won, or roughly $670 million to $700 million.
The investment gives one of South Korea’s biggest commercial banks direct exposure to the country’s dominant crypto exchange operator. Hana is buying the stake from a Kakao affiliate, and the transaction is expected to make the bank one of Dunamu’s largest outside shareholders.
The deal matters because it shows how quickly the line between traditional banking and crypto infrastructure is changing in South Korea. Banks that once treated digital assets mainly as a compliance risk are now looking at exchanges, stablecoins, remittances, custody, and tokenized finance as part of their future business.
A Major Korean Bank Moves Closer to Upbit
Hana Bank’s Dunamu investment gives it a direct position in the company behind Upbit, the most important crypto trading platform in South Korea.
Upbit controls more than 80% of South Korea’s virtual asset trading volume, making Dunamu one of the country’s most valuable digital finance companies. For Hana, that market position is the main attraction. Buying into Dunamu gives the bank access to an existing crypto ecosystem instead of forcing it to build a full exchange business from scratch.
The investment also gives Hana a stronger link to younger retail investors, crypto-native users, and future digital asset products. That could matter more as South Korea develops clearer rules for institutional crypto services and bank-linked digital asset offerings.
This is not a full takeover, and Hana will not control Dunamu through the stake. But a 6.55% position is still large enough to be strategic, especially in a company that sits at the center of South Korea’s crypto market.
Why Dunamu Is Worth a $670 Million Bet
The price of the deal shows how valuable Dunamu remains, even after several years of changing crypto market conditions.
A 1 trillion won investment for a minority stake is a big move for any bank. Hana is not paying that amount only for current exchange fees. It is paying for exposure to Upbit’s market power, Dunamu’s technology, and the possibility that South Korea’s crypto industry becomes more connected with traditional finance.
Dunamu has already become more than an exchange operator. Its position could become more important if regulated stablecoins, tokenized assets, blockchain remittances, or bank-linked crypto products expand in South Korea.
The deal also comes during a wider shift around Dunamu. Naver Financial agreed in late 2025 to acquire Dunamu in an all-stock deal worth about 15.13 trillion won, or roughly $10.27 billion, pending approvals. That planned combination would connect Upbit’s exchange business with one of South Korea’s biggest internet and fintech ecosystems.
Banks Are No Longer Sitting Outside Crypto
The Hana-Dunamu deal fits a bigger trend: banks are moving closer to crypto infrastructure because customer behavior is already changing.
South Korea has one of the most active retail crypto markets in the world. Local traders are known for fast-moving altcoin activity, strong exchange participation, and deep interest in digital assets. Banks cannot ignore that kind of demand forever, especially when fintech firms and exchanges are already building strong relationships with those customers.
Hana’s move gives the bank a safer path into the sector. Instead of launching its own exchange, it can take a minority stake in a market leader and learn from a company that already operates at scale.
That approach also helps the bank manage risk. Crypto is still volatile and heavily regulated, but owning a strategic stake is different from moving every part of the bank into digital assets at once. Hana can benefit from Dunamu’s growth while keeping its core banking business separate.
The Deal Could Open the Door to Payments and Tokenization
The longer-term story may be payments and tokenization, not just crypto trading.
Hana and Dunamu have already worked together on blockchain-based overseas remittance. That gives the investment more weight because it points to practical financial use cases. Cross-border payments, settlement, and tokenized assets are areas where banks and crypto firms can work together more naturally.
Banks bring compliance experience, fiat payment rails, customer trust, and balance sheet strength. Crypto firms bring digital asset users, blockchain infrastructure, exchange liquidity, and faster product development. If those strengths are combined carefully, South Korea could see more bank-linked crypto services in the next few years.
Stablecoins may also become part of the story if South Korea builds a clearer framework for regulated digital money. A bank with a stake in the parent of Upbit could be better placed to connect exchange liquidity with future payment or settlement products.
This does not mean Hana will immediately launch stablecoin services or tokenized products. It means the bank is positioning itself closer to the infrastructure that could support those markets later.
What Hana and Dunamu Need to Prove Next
The next step is completing the stake purchase and showing how Hana and Dunamu plan to work together beyond the investment itself.
If the deal closes in June, attention will likely shift to whether Hana expands blockchain remittance services, develops new digital asset products, or uses the Dunamu stake as part of a larger fintech strategy. Investors will also watch how the deal fits with Naver Financial’s planned acquisition of Dunamu.
The main challenge is turning strategic exposure into real business value. A minority stake gives Hana a seat closer to the crypto market, but it does not automatically create new revenue. The bank will need to prove that the partnership can support practical services that customers and regulators are comfortable with.
Dunamu also has something to prove. Upbit’s market power is strong, but the company’s long-term value will depend on whether it can expand beyond trading fees into broader digital finance.
For now, Hana’s $670 million crypto push is one of the clearest signs that South Korea’s banks are preparing for a more active digital asset future.
Key Takeaway
Hana Bank’s purchase of a 6.55% Dunamu stake is a major signal that South Korea’s banks are moving deeper into crypto infrastructure.
The deal gives Hana direct exposure to Upbit, the country’s dominant exchange, while creating room for future work around payments, remittances, stablecoins, and tokenized finance. It is not just a passive investment. It is a sign that large banks now see crypto platforms as strategic partners in the next stage of digital finance.
