<h2 id="why-is-hana-bank-s-dunamu-deal-under-review">Why Is Hana Bank’s Dunamu Deal Under Review?</h2> South Korea’s financial regulator is reportedly reviewing Hana Bank’s planned 1 trillion won purchase of a 6.55% stake in Dunamu, the operator of Upbit, as bank interest in domestic crypto platforms faces closer scrutiny. The deal, worth roughly $668 million, would see Hana Financial Group’s banking unit buy about 2.2 million Dunamu shares from Kakao Investment. The transaction would make Hana Bank the fourth-largest shareholder of Upbit’s parent company, giving one of South Korea’s major banking groups direct economic exposure to the country’s largest cryptocurrency exchange. Local outlet iNews24 cited an unnamed Financial Services Commission official as saying regulators are examining whether the transaction falls under <a href="https://financefeeds.com/south-korean-stablecoin-legislation-hits-roadblock-as-fsc-misses-deadline/" rel="noopener noreferrer nofollow">South Korea’s</a> “banking-commerce separation” framework. The issue is not only the size of the purchase, but the way the stake is being acquired. Hana Bank is buying the shares from Kakao Investment rather than directly from Dunamu, but the official said the investment would still be assessed under the same standards as a direct stake in the exchange operator. That position matters because it suggests regulators are looking at the substance of the ownership link, not only the transaction route. If a bank ends up with a meaningful stake in a crypto exchange operator, the FSC may treat the exposure as relevant even when the shares come through a secondary transaction. 
<h2 id="how-does-banking-commerce-separation-apply-to-crypto">How Does Banking-Commerce Separation Apply to Crypto?</h2> South Korea’s financial system has long operated under a supervisory principle known locally as banking-commerce separation. The framework limits ownership ties between banks and non-financial businesses, with the aim of preventing excessive cross-control between deposit-taking institutions and commercial enterprises. Crypto firms sit in a difficult part of that framework. Dunamu operates Upbit, the largest domestic cryptocurrency exchange, but virtual asset operators are not classified as traditional financial institutions. That leaves regulators with a policy problem: crypto exchanges handle financial activity, customer assets, and market infrastructure, but they do not fit cleanly into the same legal category as banks, brokerages, or insurers. Maeil Business Newspaper cited a high-ranking FSC official as saying that banking-commerce separation constraints on crypto are not explicitly written into current law and instead operate through policy and supervision. That leaves room for regulatory interpretation, but it also creates uncertainty for banks trying to invest in crypto-related businesses. For Hana Bank, the review could determine whether its Dunamu stake is treated as a permitted strategic investment, a restricted commercial exposure, or a transaction that requires additional conditions before completion. For the broader market, the case may help define how far traditional financial institutions can go in owning or backing crypto platforms without breaching supervisory expectations.

 Hana Bank’s Dunamu deal is becoming a test of how South Korea applies old bank ownership rules to crypto infrastructure. The regulator’s focus on substance over transaction structure could shape future bank investments in exchanges.

<h2 id="why-are-financial-groups-moving-into-crypto-exchanges">Why Are Financial Groups Moving Into Crypto Exchanges?</h2> Hana’s planned investment comes as South Korean financial groups show growing interest in <a href="https://financefeeds.com/binance-adds-swiss-franc-to-triparty-collateral-as-institutions-diversify/" rel="noopener noreferrer nofollow">crypto market infrastructure</a> despite tight regulation. The appeal is clear: exchanges offer exposure to trading volumes, retail investor activity, custody demand, and future <a href="https://financefeeds.com/sec-to-formalize-innovation-exemption-for-crypto-and-fintech-firms-by-2026/" rel="noopener noreferrer nofollow">digital asset products</a> without requiring banks to build full crypto platforms from scratch. Upbit is the largest domestic exchange, making Dunamu a strategic asset in any long-term view of <a href="https://financefeeds.com/oobit-and-kaia-link-up-to-bring-stablecoin-payments-to-everyday-checkouts-in-asia/" rel="noopener noreferrer nofollow">South Korea’s digital asset market</a>. A stake in Dunamu would give Hana Bank access to one of the country’s most important crypto businesses at a time when regulators are also preparing rules for tokenized securities and other digital finance products. Other groups are pursuing similar routes. In February, Mirae Asset agreed to buy a 92.06% stake in crypto exchange Korbit through Mirae Asset Consulting for about 133.5 billion won, or roughly $93 million, rather than through its securities arm. On Friday, local media also reported that OKX and Korea Investment &amp; Securities are in talks to take roughly 20% stakes each in Coinone through a new share issuance. These transactions show that crypto exposure is moving from informal partnerships toward ownership structures. Banks, securities firms, consulting affiliates, and global exchanges are looking for ways into a market where licensing, real-name account rules, and supervisory expectations make direct entry difficult. 
<h2 id="what-are-the-market-implications">What Are the Market Implications?</h2> The FSC review may become a reference point for future deals between South Korean <a href="https://financefeeds.com/circle-q3-revenue-jumps-66-as-usdc-circulation-doubles-to-73-7b/" rel="noopener noreferrer nofollow">financial institutions and crypto</a> firms. If regulators allow Hana’s purchase without major conditions, banks may have more room to take minority stakes in exchange operators. If the review results in tighter limits, financial groups may need to rely on affiliates, partnerships, or non-bank vehicles to build crypto exposure.
