Hana Bank, one of South Korea’s “Big 4” banks, has bought a $670 million stake in Dunamu, the parent company of crypto exchange Upbit. The acquisition makes Hana Bank the fourth largest shareholder in Dunamu with a 6.55% stake. This is the largest bank investment into a crypto exchange in Korean history, and it lands as part of a broader move by Korean banks to position themselves directly inside the digital asset space rather than around it.

Dunamu owns Upbit, the largest crypto exchange in South Korea by volume. Upbit handles the majority of retail crypto trading activity in the country and has been a dominant fixture in the Korean market for years. 

A 6.55% stake in Dunamu doesn’t give Hana Bank full control, but it gives the bank a significant seat at the table for one of Asia’s most active crypto trading platforms.

Hana Bank gets exposure to Dunamu’s growth, access to crypto market data flows, and a strategic relationship that can be leveraged across the bank’s own product roadmap.

Hana Financial Group said the deal is aimed at accelerating financial innovation tied to digital assets and expanding joint business projects with Dunamu. That framing matters. It’s not a passive financial investment. It’s strategic positioning for products and services that will come out of the partnership.

This isn’t an isolated event. Woori Bank partnered with MoonPay in April on a won-backed stablecoin. That partnership focused on the stablecoin infrastructure layer. Hana Bank’s investment in Dunamu focuses on the exchange and trading layer.

Two of Korea’s Big 4 banks have now made significant digital asset moves within a span of weeks. The pattern suggests other Korean banks are likely watching closely and considering their own positioning. South Korea has historically been one of the most active retail crypto markets globally, and the traditional banking sector is finally moving to capture that activity rather than compete against it externally.

The Hana Bank and Dunamu relationship will likely produce joint products that combine traditional banking infrastructure with crypto exchange capabilities. Custodial services, stablecoin integrations, payment rails, and tokenized asset products all sit in the obvious overlap zone.

Hana Bank’s $670M investment in Dunamu is the largest bank-to-crypto-exchange deal in Korean history. The 6.55% stake makes Hana the 4th largest shareholder in the parent company of Upbit. Combined with Woori Bank’s stablecoin partnership in April, the move signals that Korea’s Big 4 banks are positioning directly inside the crypto ecosystem.

The framing from Hana Financial Group is clear. This is about innovation and joint business projects, not passive exposure. The traditional banking sector in Korea is moving into digital assets at scale.
