"We will create an ecosystem covering the issuance, distribution, use and circulation of a won-denominated stablecoin." — Hana Financial Group, Joint Statement with Dunamu, May 15, 2026
South Korea's financial system is undergoing structural convergence between traditional banking and digital asset infrastructure. On May 15, 2026, Hana Financial Group committed 1 trillion won ($670 million) for a 6.55% stake in Dunamu, operator of Upbit — the exchange that controls approximately 72% of domestic crypto trading volume. The deal, set to close June 15, marks the largest equity investment by a Korean bank into a digital asset enterprise.
The transaction arrives amid a broader regulatory reset: the nine-year ban on corporate crypto investment was lifted in January 2026, a Digital Asset Basic Act is advancing through the National Assembly, and a consortium of eight major banks is developing a won-pegged stablecoin. Separately, Naver's $10.3 billion all-stock acquisition of Dunamu — currently delayed to September 30 by antitrust review — would create the country's dominant fintech-crypto conglomerate. Korean won pairs now represent 30% of global spot crypto volume, with approximately $2.6 billion in daily domestic exchange turnover across 11.13 million registered accounts.
Hana Financial Group will acquire a 6.55% stake in Dunamu for approximately 1 trillion won ($670 million), becoming the company's fourth-largest shareholder. The deal closes June 15, 2026.
The investment is not passive. Hana and Dunamu have outlined four collaboration tracks:
According to Seoul Economic Daily, Hana's foreign exchange infrastructure gives it a strategic advantage in the won stablecoin race, positioning the bank as the likely first mover among Korean lenders in cross-border digital settlement.
Dunamu reported net profit of 708.8 billion won on revenue of 1.56 trillion won in fiscal 2025. The $670 million investment implies a full Dunamu valuation of approximately $10.2 billion at the 6.55% stake level.
South Korea operates one of the world's most concentrated crypto trading markets. Key metrics:

The market exhibits structural characteristics distinct from Western counterparts:
Six players are competing to issue Korea's first regulated won-pegged stablecoin, according to Seoulz reporting. A consortium of eight major commercial banks is developing a shared stablecoin infrastructure, while Hana-Dunamu represents the most capitalized bilateral effort.
The economic case is straightforward: Tether (USDT) has historically traded at a 5% markup on Korean exchanges, and approximately $40 billion leaked to offshore dollar-denominated stablecoins in Q1 2025 alone. A functional won stablecoin would:
The Bank of Korea supports a bank-led issuance model requiring commercial banks to hold at least 51% of each stablecoin issuer's equity. The Financial Services Commission opposes this ownership threshold, arguing it would exclude fintech participants. This dispute has delayed the stablecoin framework multiple times.
Regulators expect only 2-3 bank-centered consortia to qualify as initial issuers once rules are finalized, with the framework targeting passage by late 2026.
South Korea's Digital Asset Basic Act represents the most comprehensive crypto legislative effort in Asia. Key provisions:
Stablecoin classification: Stablecoins used in cross-border or foreign exchange transactions will be classified as "means of payment" under the Foreign Exchange Transactions Act. Issuers will require authorization, must maintain 100%+ reserves in high-quality assets (bank deposits or government bonds), and must ensure full redemption rights.
Licensing regime: Crypto businesses face mandatory licensing, capital requirements, disclosure obligations, and operational standards comparable to traditional financial institutions.
Corporate investment framework: Listed companies and professional investors may allocate up to 5% of annual equity capital to digital assets. Investments must target the top 20 cryptocurrencies by market capitalization on Korea's five registered exchanges.
Timeline: The Act was proposed in April 2026 by the ruling Democratic Party. Full implementation is targeted for late 2026 or 2027 following consultations. Over 100 amendments are expected during the legislative process.
The Act builds on the Virtual Asset User Protection Act (effective July 2024), which established investor protections but did not address market structure, stablecoin issuance, or institutional participation.
In parallel with the Hana investment, Naver Financial is executing a $10.3 billion all-stock acquisition of Dunamu via a share-swap at a ratio of 2.54 Naver Financial shares per Dunamu share.
Status as of May 2026: The deal is delayed. The shareholder meeting has been pushed from May 22 to August 18. Closing has moved from June 30 to September 30 due to antitrust review by the Korea Fair Trade Commission. Proposed legislation to cap major shareholders' stakes in crypto exchanges adds further uncertainty.
Post-merger plans: Dunamu intends to pursue a Nasdaq IPO immediately following completion of the share exchange. The combined entity would create Korea's dominant digital finance platform, integrating Naver's 45 million monthly active users with Upbit's trading infrastructure.
The coexistence of the Naver acquisition and Hana's strategic investment creates a complex ownership structure. After the merger closes, Hana's 6.55% stake would be in a Naver Financial subsidiary rather than an independent Dunamu.
In January 2026, South Korea ended a nine-year ban on corporate cryptocurrency investment. The regulatory framework:
The policy aligns Korea with the United States, Hong Kong, and Canada, where institutional crypto participation is established. The timing is deliberate: Seoul's "2026 Economic Growth Strategy" includes stablecoin legislation and potential spot crypto ETF approvals.
At $77.5 billion in total market size, even modest corporate allocations could meaningfully increase domestic liquidity. If 3,500 entities each allocated the full 5% cap, the theoretical maximum capital inflow would depend on aggregate equity values of eligible firms — a figure not yet published by regulators.
The convergence of banking capital with crypto exchange infrastructure creates new value distribution channels:
Fee economics: Upbit's 1.56 trillion won ($1.1 billion) annual revenue is generated almost entirely from trading fees. The Hana partnership introduces revenue-sharing opportunities in wealth management, stablecoin transaction fees, and remittance services that currently flow to SWIFT intermediaries.
Stablecoin float: A won stablecoin backed by 100%+ reserves in bank deposits or government bonds generates yield on idle reserves. With the Bank of Korea base rate at current levels, the reserve float alone represents meaningful revenue for issuers — a dynamic identical to Tether's $4.5 billion quarterly profit model.
Capital recapture: The $110 billion annual outflow to foreign platforms represents lost fee revenue for domestic exchanges. A competitive won stablecoin and expanded trading pairs could reverse a portion of this flow.
Infrastructure costs: Dunamu's GIWA Chain and the broader bank-consortium stablecoin require node operators, compliance infrastructure, and oracle services. The economic value distribution for these services remains undefined, as is typical in pre-launch infrastructure phases.
South Korea's financial system is executing a compressed convergence between traditional banking and digital asset infrastructure. The Hana-Dunamu deal, the Digital Asset Basic Act, the won stablecoin race, and the Naver mega-merger are not isolated events — they are components of a coordinated national strategy to capture value currently leaking to offshore platforms and foreign intermediaries.
The structural challenge remains regulatory coherence. The Bank of Korea and FSC disagree on stablecoin governance. Antitrust authorities are reviewing the Naver merger. Corporate allocation caps constrain institutional flows. Whether Korea's crypto market evolves into a bank-dominated utility or retains its current exchange-centric structure will depend on which regulatory faction prevails in the stablecoin framework debate.
The data point that matters: $110 billion left Korea in 2025. Every policy decision in 2026 is, at its core, an attempt to keep that capital onshore.
