Hana Bank and Dunamu: What a $670M Deal Actually Includes

When did a traditional bank buying crypto exchange shares stop being surprising news?

In South Korea, that moment may have just arrived. Hana Bank, one of the country's largest commercial lenders, has acquired a 1 trillion won ($670 million) stake in Dunamu, the company that runs Upbit. That's the largest crypto exchange in South Korea by trading volume. The deal closed on May 15, 2026. It's the biggest single investment a Korean bank has ever made into a digital asset firm, confirmed by Financial Group in a regulatory filing on Friday.

This isn't a small fintech experiment. It's a $670 million commitment.

Hana Bank and Dunamu: What a $670M Deal Actually Includes

They purchased 2,284,000 shares in Dunamu from Kakao Investment at a price of 1.003 trillion won. That gives a 6.55% stake, making it Dunamu's fourth-largest shareholder. The top three remain founder and chair Song Chi-hyung at 25.51%, Vice Chair Kim Hyoung-nyon at 13.1%, and Woori Technology at 7.2%.

Kakao Investment, the investment arm of South Korea's largest internet company, originally put 35.5 billion won into Dunamu when the exchange launched in 2012. That investment grew more than 300-fold. Kakao still retains a 4% stake after this sale.

Here's what makes this more than just a share purchase:

• MOU signed simultaneously — Hana Bank and Dunamu committed to joint product development covering blockchain financial services, stablecoins, and overseas remittances

• Wealth management integration — Upbit and Financial platforms will connect to build a new model covering both traditional and digital assets

• Global expansion targeted — Hana's international network across 20+ countries pairs with Dunamu's blockchain technology for overseas digital asset businesses

Dunamu posted 709 billion won in net profit on 1.56 trillion won in revenue last year. Its total assets reached 13.17 trillion won. These aren't speculative numbers. This is a profitable business Hana Bank just bought into.

Hana Bank Is Replacing SWIFT Here Is What That Means

The deeper story behind this deal started months before the stake purchase.

Since late 2025, Hana Bank and Dunamu have been building a blockchain-based remittance system designed to replace the SWIFT network, the decades-old messaging system all international banks currently use. A proof of concept completed in February 2026 showed blockchain could significantly reduce settlement times and transaction costs compared with the traditional SWIFT framework. The system also met key compliance requirements, including anti-money laundering and know-your-customer checks.

The technology running this is called Giwa Chain, Dunamu's own Layer 2 blockchain. Under the SWIFT framework, the payment instruction and the actual movement of funds are two separate steps, which generates delays and additional costs. The system built on Giwa Chain merges both stages into a single, real-time process.

POSCO International, which processes around 40,000 overseas remittance transactions annually across its network spanning 51 countries, plans to apply the technology to actual fund flows within its trade operations to validate its effectiveness.

The global remittance market was valued at $860 billion in 2024. Industry analysts project that blockchain-based deposit token systems could reduce cross-border settlement costs by 40 to 80 percent while improving transaction speed by 90 percent. That's the market Hana Bank and Dunamu are targeting together.

What Hana Bank and Dunamu Build Next Changes Everything

Based on publicly available data and market sources, the roadmap from this investment points in three clear directions. No guaranteed outcomes are implied.

Won-backed stablecoin: They plans to work with Dunamu on won-backed stablecoins covering issuance, circulation, use, and redemption. Korean lawmakers are accelerating a draft stablecoin bill, with a framework expected imminently. Hana Bank's timing here is not accidental.

Wealth management: Hana's plans to combine its fund, pension and trust capabilities with Dunamu's digital asset infrastructure to build a new model for managing both traditional and digital assets. Every Upbit user becomes a potential Hana's Financial wealth management client. Every Hana client gets digital asset access through Upbit's interface.

Regulatory context: The alliance between an established financial institution and a virtual asset operator heralds business cooperation going beyond simple services such as real-name accounts for virtual asset transactions to digital financial services, including stablecoin projects. South Korean regulators have been pushing crypto firms to improve governance structures. Hana Bank's ownership stake gives Dunamu exactly the institutional credibility regulators want to see.

Hana's Financial Group Chairman Ham Young-joo confirmed the strategic intent directly: "This investment is a strategic move to accelerate financial innovation in digital assets. By working with Dunamu, we aim to help shape Korea's blockchain ecosystem and bring the country's digital asset industry closer to the global forefront."

All data cited is based on publicly available regulatory filings, official statements, and market sources as of May 15, 2026. No guaranteed outcomes are stated or implied.

Conclusion

Hana Bank just placed the largest-ever bet by a Korean lender on digital assets: $670 million, a 6.55% stake, and a roadmap covering stablecoins, blockchain remittances, and wealth management. South Korea's banking sector has been watching cautiously for years. With this deal, They stopped watching and started owning. The next chapter for Korean crypto banking begins now.
