Hana Bank will purchase a 6.55% stake in Dunamu, operator of South Korea's largest crypto exchange Upbit, for approximately $672.5 million from a Kakao affiliate. This transaction, set to close June 15, will establish the commercial lender as the exchange's fourth-largest shareholder.

Parent Hana Financial Group framed the move as its most significant digital-asset investment to date. The bank's chairman, Ham Young-joo, stated the purchase accelerates "financial innovation based on digital assets," following a prior agreement with Dunamu to co-develop new business models.

The deal underscores growing institutional acceptance of cryptocurrency platforms among traditional finance firms in Korea. By acquiring a substantial position in Dunamu, Hana Bank gains direct exposure to the burgeoning crypto trading market while positioning itself at the forefront of blockchain-integrated financial services.
