A Nation Divided Over Who Gets to Mint Digital Won

As of April 2026, South Korea's most consequential financial policy debate centers not on interest rates or housing — but on who will be allowed to issue won-denominated stablecoins. The Bank of Korea's insistence on a "51% rule" — requiring bank consortiums to hold a majority stake (50%+1 share) in any stablecoin-issuing entity — has triggered a multi-front regulatory battle pitting the central bank against the Financial Services Commission (FSC), fintech innovators, and a faction of ruling-party lawmakers. With the global stablecoin market exceeding $266.7 billion and 99.8% of that denominated in U.S. dollars, the absence of a legitimate KRW stablecoin represents both a gaping market opportunity and a growing threat to Korean monetary sovereignty.

On April 4, 2026, the FSC convened its first Virtual Asset Committee meeting of the year in Seoul, followed by a party-government consultative session on April 5 to finalize the ruling party's legislative direction on the Digital Asset Basic Act Phase 2. The outcome of these meetings could determine the trajectory of Korea's digital currency future for years to come.

Legislative Background: A Long and Winding Road

South Korea's virtual asset regulatory journey began with the Virtual Asset User Protection Act (Phase 1), enacted in July 2024. That law focused on investor protection and exchange oversight — trading safeguards, custody requirements, and anti-fraud measures — but deliberately excluded stablecoin issuance from its scope. The more ambitious Digital Asset Basic Act (Phase 2), intended to govern stablecoin issuance, security token offerings, and exchange ownership structures, has been in development since mid-2025.

However, the bill has been repeatedly delayed. Originally slated for government finalization by the end of 2025, the deadline slipped to January 2026, then February, then March. According to CoinDesk, the core sticking point has been the Bank of Korea's 51% ownership requirement, which the FSC views as potentially innovation-killing. The Bank of Korea argues that since won-pegged stablecoins function as de facto private money, only bank-controlled entities — already subject to prudential supervision, capital adequacy requirements, and deposit insurance frameworks — should be entrusted with issuance.

A critical structural constraint compounds the debate: under Korea's Banking Act, individual banks can hold a maximum of 15% equity in non-banking entities. This means at least four banks must join forces to reach the 51% threshold, transforming stablecoin governance into a complex game of banking alliances.

The 51% Rule: Anatomy of the Dispute

The Bank of Korea's Case for Bank Control

BOK Governor Rhee Chang-yong has been the most vocal champion of the 51% rule, warning that allowing non-bank entities to issue stablecoins could "cause major chaos" in the financial system. The central bank's argument rests on three pillars: monetary policy transmission (won-pegged stablecoins directly affect money supply dynamics), regulatory efficiency (banks already operate within comprehensive supervisory frameworks), and AML/KYC compliance (banks possess mature infrastructure for combating financial crime).

The BOK views stablecoins not as mere crypto tokens but as a potential parallel monetary system. If a tech giant like Kakao or Naver were to issue a widely adopted won stablecoin outside the banking system's oversight, it could undermine the central bank's ability to manage liquidity and implement monetary policy — a concern that resonates with central bankers globally.

The FSC and Fintech Counter-Argument

The FSC has taken a more nuanced position. While accepting the principle of bank participation in stablecoin consortiums, the regulator has resisted codifying the specific 51% threshold into law. According to Etoday, the FSC's stance is that "regulations should be carefully designed to ensure stability, while distribution and service areas should be open for fintech companies to compete and innovate."

The Democratic Party of Korea's (DPK) Digital Asset Task Force, led by Rep. Ahn Do-geol with 20 external advisers, has emerged as a powerful institutional opponent of the rule. Ahn has argued that "issuers should be selected based on their ability to advance innovation rather than their institutional classification," noting that a majority of the task force's expert advisers voiced concerns about the bank-centric approach.

The FSC has pointed to compelling international precedents. Under the EU's Markets in Crypto-Assets (MiCA) regulation, 14 out of 15 licensed stablecoin issuers are electronic money institutions — not banks. Japan's fintech-led yen stablecoin projects offer another example of regulated innovation outside traditional banking channels. Critics argue that Korea's 51% rule lacks global legislative precedent and risks creating a Galapagos-style regulatory island.

The Consortium Land Grab

Despite the unresolved regulatory framework, Korean banks have already launched an aggressive race to form stablecoin consortiums. According to Invest Chosun, Hana Financial Group has moved most aggressively, securing partnerships with six financial institutions: BNK Financial (Busan and Gyeongnam banks), iM Financial (iM Bank), SC First Bank, OK Savings Bank, and JB Financial (Gwangju and Jeonbuk banks). With the 15% per-bank ownership cap requiring at least four banking partners, Hana's first-mover advantage has made it significantly harder for rival consortiums to assemble viable coalitions.

KB Financial Group converted its stablecoin division within its Virtual Asset Response Council into a permanent organization in the second half of 2025 and is the only bank that directly developed its own infrastructure for the BOK's CBDC demonstration project. Shinhan Bank conducted cross-border remittance stablecoin tests on the Hedera Hashgraph network in 2023 and is now piloting deposit-token payments through its delivery app "Ttanggyeo" and Shinhan EZ Insurance travel products.

Meanwhile, the BOK's Project Hangang Phase 2 CBDC experiment now involves nine banks — KB Kookmin, Shinhan, Woori, Hana, Industrial Bank of Korea, NH NongHyup, Busan Bank, plus newly added Gyeongnam Bank and iM Bank. Financial News quoted industry sources suggesting that CBDC and stablecoin systems will likely converge into a structure where "banks control both issuance and distribution" — a prediction that would vindicate the BOK's approach.

Practical Implications for Investors and Industry

No legally authorized KRW stablecoin currently exists. Investors should treat offshore KRW-pegged tokens (such as KRWQ or similar products) with caution, as the Digital Asset Basic Act is expected to prohibit domestic circulation of unauthorized won stablecoins once enacted. Regulatory risk is the primary concern for anyone currently using or planning to use KRW-denominated digital tokens.

The emerging framework will require stablecoin issuers to maintain 100% reserves in bank deposits or government securities, with mandatory segregation of customer and corporate assets. While this provides robust investor protection, it constrains the yield-generating business models that have driven stablecoin adoption elsewhere.

On taxation, Korea's crypto gains tax — currently set at 20% on profits exceeding KRW 2.5 million — has been deferred to January 2027. Stablecoin transactions themselves are unlikely to be taxable events, but capital gains realized through stablecoin-mediated crypto trading will fall under the existing tax framework. Tax professionals should monitor the implementing decrees for specific provisions on stablecoin issuance, redemption, and conversion taxation.

Outlook: June Elections and the Legislative Clock

The Digital Asset Basic Act faces a critical timeline challenge. Following the April 5 party-government consultative meeting, the bill is expected to enter the National Assembly introduction process. However, with June 2026 local elections approaching, legislative activity is likely to grind to a halt as lawmakers shift focus to campaigning. Even if introduced, the bill must pass through the Political Affairs Committee, the Legislation and Judiciary Committee, and a full plenary vote — a process typically requiring several months. Subsequent implementing decrees will add additional months of regulatory development.

Three scenarios are plausible. In the optimistic case, the bill is introduced in April, clears the Political Affairs Committee before the June election, passes the plenary in the second half of 2026, and implementing decrees are finalized by early 2027 — enabling KRW stablecoin launches by mid-2027. In the base case, the bill's introduction slips past the election, substantive National Assembly review begins in late 2026, and implementation stretches to late 2027 or early 2028. In the pessimistic case, the 51% rule deadlock persists, the bill stalls indefinitely, and dollar-denominated stablecoins continue to dominate Korea's digital asset ecosystem by default.

KB Securities analysts have cautioned that "even after the law passes, markets must continuously monitor policy direction and regulatory intensity, as implementing decrees will take additional months to finalize." Adding urgency is the rapid advancement of U.S. stablecoin legislation, which threatens to cement dollar dominance in global stablecoin markets while Korea remains on the sidelines.

Conclusion: Digital Sovereignty at a Crossroads

The 51% rule debate transcends a simple percentage dispute. At its core, this is a contest over how Korea preserves monetary sovereignty in the digital age and where it positions the balance between financial stability and innovation. With approximately 16 million Korean crypto investors holding an estimated KRW 104 trillion ($80 billion) in digital assets — roughly 5% of national GDP — the continued absence of a regulated KRW stablecoin only accelerates capital migration toward dollar-based alternatives. The April 2026 party-government consultations represent perhaps the last realistic window for consensus before election politics freeze the legislative calendar. For investors, financial institutions, and blockchain firms alike, the coming weeks will determine whether Korea enters the global stablecoin race as a contender — or watches from the sidelines as the digital dollar cements its dominance across Asia's largest crypto market.
