"For the first time in nearly nine years, Korean companies will be legally permitted to issue KRW stablecoins. The question is not whether it happens, but who controls it." — Ryan Yoon, Tiger Research, 2026 Korea Crypto Market Guide
South Korea is assembling the most contested national stablecoin market in Asia. Six distinct groups — an eight-bank consortium, two tech conglomerates, a global payment infrastructure firm, a blockchain gaming alliance, and two card processors — are simultaneously building won-denominated stablecoin products for a domestic user base of 18 million crypto holders. The market they are chasing is not theoretical: stablecoins already account for 47.3% of South Korea's cryptocurrency outflows, with ₩26.87 trillion ($19.5 billion) in dollar-pegged stablecoin volume leaving Korean exchanges in Q1 2025 alone.
The catalyst is legislative. The Digital Asset Basic Act (DABA) is expected to clear the National Assembly in 2026, creating for the first time a legal framework for won-backed stablecoin issuance. But a regulatory deadlock between the Bank of Korea and the Financial Services Commission over who may issue stablecoins — banks only, or fintechs too — has delayed the bill and created a parallel race to lock in infrastructure before rules are finalized. Meanwhile, the Bank of Korea's CBDC pilot sits paused since Q2 2025, leaving the private sector to fill the digital-won vacuum.
The stakes are structural. Korea processes ₩200 trillion ($145 billion) annually through card networks alone. Whoever controls the won stablecoin rails controls the settlement layer for Asia's fourth-largest economy.
South Korea has the highest per-capita crypto adoption rate among developed economies. According to CoinGecko and Tiger Research's 2026 Korea Crypto Market Guide, over 18 million South Koreans — more than one-third of the adult population — hold digital assets. Collectively, these users held ₩102.6 trillion (~$70.3 billion) in crypto as of early 2025.
The domestic exchange market is concentrated. Upbit, operated by Dunamu, controls approximately 65% of trading volume as of Q4 2025, down from 80% in late 2024. Upbit and Bithumb together hold roughly 87% of domestic market share, with Coinone at approximately 10%. Upbit processed ₩833 trillion (~$642 billion) in trading volume during H1 2025 and regularly ranks among the global top five for spot volume.
The stablecoin dynamic is the critical data point. According to Financial Services Commission data, stablecoins accounted for 47.3% of total cryptocurrency outflows from Korean exchanges in Q1 2025, worth ₩26.87 trillion. In absolute terms, roughly $40 billion left Korean exchanges in Q1 2025, with the bulk flowing into dollar-denominated stablecoins like USDT and USDC. Korean won-pegged stablecoins currently represent less than 1% of total stablecoin market capitalization globally.
This ratio — massive stablecoin usage, near-zero won-denominated supply — is the gap every contender is targeting.
The single largest initiative is a coalition of eight major commercial banks: KB Kookmin, Shinhan, Woori, NongHyup, Industrial Bank of Korea, Suhyup, Citibank Korea, and Standard Chartered First Bank. Announced in mid-2025, the consortium is jointly developing a won-pegged stablecoin targeting late-2025 to 2026 launch.
The consortium is evaluating two structural models: a trust-based structure where assets are held in a legally protected trust for token holders, and a 1:1 deposit-backed token fully collateralized by Korean won deposits at participating banks. Both models mandate 100% reserves in low-risk instruments (bank deposits or government bonds) under independent custodian management.
The Bank of Korea strongly favors this approach. Its position is that only bank-led consortiums with majority (51%) ownership should be permitted to issue stablecoins, citing systemic stability concerns.
KB Kookmin Bank has separately filed multiple stablecoin-related trademark applications, signaling individual product ambitions beyond the consortium structure.
Naver Financial announced a $10.3 billion all-stock acquisition of Dunamu, the parent company of Upbit. The shareholder vote was originally scheduled for May 22, 2026, with the stock exchange set for June 30, but the closing date has since been pushed to September 30, 2026, pending regulatory approvals from the Fair Trade Commission and credit information regulators.
The strategic rationale is vertical integration: combining Upbit's exchange infrastructure (8+ million verified users, $2-4 billion daily spot volume) with Naver's payments, search, messaging, and shopping ecosystem to create what analysts describe as a "super app." A won stablecoin integrated into Naver Pay would have immediate distribution to tens of millions of Korean consumers.
Kakao Group is building a won stablecoin ecosystem by connecting KakaoPay, KakaoBank, and KakaoTalk into a unified digital wallet. According to Chosun Daily (February 2, 2026), KakaoPay and KakaoBank are both establishing stablecoin payment infrastructure. KakaoTalk, with its near-universal penetration among Korean smartphone users, provides the distribution layer that no bank consortium can replicate.
Naver Pay, Kakao Pay, and Toss are all reportedly building parallel stablecoin payment rails, creating a three-way fintech race beneath the bank-consortium layer.
On April 30, 2026, MoonPay Korea announced it would serve as infrastructure partner for global distribution and cross-border settlement of Korean won-backed stablecoins, signing its first banking MOU with Woori Bank — one of Korea's four largest commercial banks.
MoonPay also invested in Finger, a Korean fintech firm, in an approximately ₩110 billion (~$76 million) transaction alongside Sungho Electronics, Seoryong Electronics, and Pantos Holdings. The initiative covers issuance, orchestration, and real-world commercial usage of a KRW stablecoin, with MoonPay providing global wallet access and currency conversion infrastructure.
The cross-border angle is notable. Asia accounts for approximately 60% of real stablecoin payment volume globally, and MoonPay's network positions the won stablecoin for remittance, merchant settlement, and institutional payment use cases beyond the domestic market.
The Global Alliance for KRW Stablecoins (GAKS), launched in November 2025 and led by blockchain gaming firm WEMADE, signed Chainlink Labs in January 2026. Chainlink will supply decentralized oracle data feeds, Cross-Chain Interoperability Protocol (CCIP) for secure asset transfers, and compliance and privacy tooling for regulated won stablecoins.
Separately, Chainlink and SOOHO.IO launched Project Namsan, focused on KRW stablecoin foreign exchange and cross-border payments. A prior initiative, Project PAX, involved multi-bank interoperability testing with Shinhan Bank, NH NongHyup Bank, and K Bank.
Shinhan Card, South Korea's largest card issuer with 28 million cardholders and ₩200 trillion ($145 billion) in annual transaction volume, signed a memorandum of understanding with the Solana Foundation on April 30, 2026. The deal follows a completed six-project proof of concept and will advance to testnet simulation of real merchant payment flows.
Three workstreams are underway: Solana testnet payment simulation, non-custodial wallet verification, and stablecoin settlement process design from initial card transaction through merchant payout. Shinhan indicated any commercial launch would depend on the direction of the Digital Asset Basic Act.
BC Card, South Korea's largest payment processor, completed a separate two-month pilot (launched October 2025) enabling foreign users to convert stablecoins into digital prepaid cards for QR-code payments at domestic merchants. The pilot involved Wavebridge, Aaron Group, and Global Money Express, and required no new merchant hardware.
The Digital Asset Basic Act was expected to clear the National Assembly in early 2026 but has stalled over a fundamental disagreement between South Korea's two primary financial regulators.
Bank of Korea (BOK) position: Only bank-led entities with minimum 51% bank equity ownership should issue won stablecoins. The BOK argues banks are the only institutions capable of ensuring monetary stability, managing redemption risk, and maintaining systemic safeguards. New governor Shin Hyun-song, in an April 21, 2026 address, prioritized CBDCs and bank-issued deposit tokens while conspicuously omitting stablecoins from his remarks.
Financial Services Commission (FSC) position: A rigid 51% rule would suppress competition and block fintech firms with superior technical capability. The FSC cites the EU's MiCA framework, where 14 of 15 licensed stablecoin issuers are electronic money institutions, not banks. The FSC favors allowing any company meeting a minimum equity threshold (lawmakers have suggested ₩500 million, approximately $360,000) to apply for issuance rights.
The compromise framework under discussion mandates a consortium structure where banks must hold at least 51% equity but technology companies can participate as minority stakeholders. Reserve requirements under the draft mandate 100% backing in low-risk instruments under independent custodian management, with full redemption protections.
The government's bill was delayed after the FSC and BOK failed to resolve their differences. A government-sponsored bill is now expected by end of 2026, with full enforcement to follow.
The Bank of Korea halted its digital won CBDC pilot in Q2 2025, citing high infrastructure costs, limited commercial incentives, and lukewarm bank participation. In March 2026, the BOK resumed limited real-world testing with nine banks, but the program's scope and timeline remain unclear.
The CBDC pause has created a policy vacuum. While the central bank originally envisioned a state-controlled digital currency, private-sector stablecoins are advancing faster. The BOK will reconsider its CBDC plans later in 2026, but the market is not waiting — six separate private initiatives are building infrastructure on the assumption that won stablecoins, not a digital won CBDC, will dominate the consumer payments layer.
The FSC has separately signaled that dollar-denominated stablecoins like USDT and USDC may be excluded from the approved list for corporate digital asset investment, further channeling domestic institutional demand toward won-denominated alternatives.
The infrastructure choices being made now will determine the technical architecture of Korea's stablecoin economy.
Solana has positioned itself as the settlement layer for card payments, with Shinhan Card's PoC running six projects on its network before the MOU was signed. The testnet simulation phase will assess network stability and merchant settlement latency.
Chainlink is embedded at the oracle and interoperability layer, supplying data feeds, CCIP cross-chain bridging, and compliance tooling through GAKS and Project Namsan. Its involvement in Project PAX with multiple Korean banks suggests it may become the default middleware for multi-bank stablecoin operations.
MoonPay is building the global distribution and conversion layer, with wallet access and currency conversion infrastructure designed to make won stablecoins usable beyond Korean borders.
The Ministry of Economy and Finance has separately selected a regulatory sandbox project using tokenized deposits for government spending management, with a rollout planned for Q4 2026 in Sejong City. This represents a parallel state-backed experiment in programmable money alongside the private stablecoin initiatives.
South Korea is running a controlled experiment in stablecoin market design. The outcome will determine whether a bank-led consortium, a tech super-app, a card processor, or a cross-border infrastructure provider captures the settlement layer for an $145 billion annual card payments economy.
The data suggests this market will not consolidate around a single winner. The bank consortium controls regulatory access. Naver-Dunamu and Kakao control consumer distribution. Shinhan Card and BC Card control merchant acceptance. MoonPay controls global reach. WEMADE-Chainlink controls interoperability.
The missing variable is legislation. Until the Digital Asset Basic Act passes, all six contenders are building infrastructure against an uncertain regulatory framework. The BOK-FSC deadlock on the 51% bank-equity rule will determine whether this becomes a bank-dominated market or an open competitive field.
What is not uncertain is the demand. Eighteen million Korean crypto users moved $40 billion into dollar stablecoins in a single quarter. The won stablecoin race is not about creating a market. It is about recapturing one.
