"Won-denominated stablecoins should be issued through bank-led consortiums." — Bank of Korea, testimony to the National Assembly Finance Committee, July 2026
South Korea is running at least six parallel stablecoin initiatives simultaneously. In the span of 10 days in July 2026, Gyeonggi Province announced a government stablecoin pilot starting August, Toss signed an MOU with Optimism to test won-pegged tokens for 30 million users, and the Bank of Korea reiterated its position that only bank-led consortiums should issue fiat-linked tokens. Meanwhile, KB Financial has already completed a pilot that cut cross-border transaction fees by 87%, and the legislative deadlock over who may issue stablecoins continues to delay the Digital Asset Basic Act.
The stakes are quantifiable: approximately $40 billion left Korean crypto exchanges in Q1 2025 alone, most of it flowing into foreign dollar-backed stablecoins. Korean won pairs now account for 30% of global spot crypto trading volume, with $26 billion in weekly turnover. The country that produced 16 million active crypto investors — one-third of its adult population — has no domestic won stablecoin in production. That gap is now generating a multi-front race between banks, fintechs, blockchain startups, and government agencies.
South Korea's Digital Asset Basic Act — the country's first comprehensive crypto law — has been stalled since December 2025 over a single question: who can issue stablecoins.
The Bank of Korea insists that stablecoin issuers must operate through consortiums in which banks hold at least a 51% stake. The Financial Services Commission (FSC) argues the law should avoid a rigid ownership threshold. This disagreement has now delayed the legislation twice.
The draft law, proposed by the ruling Democratic Party in April 2026, would require:
President Lee Jae Myung has publicly prioritized a domestic won stablecoin, framing it as a monetary sovereignty issue against dollar-denominated stablecoin dominance. However, the bureaucratic stalemate between the FSC and BOK continues. The next legislative window opened after the June local elections, but no resolution has been announced as of July 12.
The Bank of Korea launched Phase 2 of Project Hangang on March 18, 2026, expanding from seven to nine commercial banks. The participating institutions are: KB Kookmin, Shinhan, Woori, Hana, NH Nonghyup, IBK Industrial, BNK Busan, BNK Gyeongnam, and iM Bank.
The architecture uses a wholesale CBDC issued to financial institutions, with blockchain-based deposit tokens distributed to end users. Phase 2 introduced:
Large-scale follow-up transactions involving all nine banks are scheduled for H2 2026. The BOK signaled in July that it plans to expand Project Hangang into foreign bond investment infrastructure, suggesting the deposit token layer may eventually support cross-border securities settlement.
The central bank's approach is conservative by design. Deposit tokens remain within the regulated banking system, backed by commercial bank liabilities and underpinned by BOK infrastructure. This contrasts sharply with the decentralized approaches being tested by private-sector competitors.
On July 10-11, Gyeonggi Province — South Korea's most populous administrative region — announced what it calls the country's first government-led stablecoin proof of concept, set to begin in August.
Key details:
The pilot targets specific government use cases: local currency programs, public subsidies, vouchers, and inter-agency payment settlement. Unlike private-sector stablecoin projects aimed at consumer payments or trading, this initiative evaluates whether blockchain infrastructure can improve public fund tracking and disbursement.
The use of zero-knowledge proofs is notable. ZKPs allow the system to verify that a recipient qualifies for a subsidy without exposing their personal data on-chain — a requirement for any government payment system handling sensitive citizen information.
Three private-sector tracks are running concurrently:
Toss, Korea's largest fintech platform with 30 million users, signed an MOU with Optimism and Sunnyside Labs for a three-month proof of concept testing a KRW-pegged stablecoin on the OP Stack (Ethereum Layer 2).
The PoC evaluates three capabilities:
Toss holds integrated licenses spanning banking, securities, and payments. At the Blockchain Meetup Conference in Seoul in March 2026, the company declared its intent to both issue and distribute stablecoins — a dual role that the BOK's bank-majority rule would likely prohibit without legislative changes.
KB Financial Group, South Korea's largest banking conglomerate, completed a stablecoin pilot for offline payments and cross-border remittances on the Kaia blockchain.
Results:
KB signaled readiness to launch commercial stablecoin services pending Digital Asset Basic Act passage.
Kakao, with KakaoTalk on effectively every smartphone in Korea and 42 million KakaoPay registered users, has not disclosed specific pilot timelines but is widely identified as a leading contender. The company's existing payment infrastructure and messaging distribution channel give it the largest potential user reach of any competitor.
The stablecoin race is producing a fragmented technology landscape:
| Initiative | Blockchain | Privacy Tech | Status | |-----------|-----------|-------------|--------| | Project Hangang (BOK) | Proprietary wholesale CBDC layer | Banking-grade (centralized) | Phase 2, 9 banks | | Gyeonggi Province | Undisclosed (ZKrypto-built) | Zero-knowledge proofs | Starts August | | Toss/Optimism | OP Stack (Ethereum L2) | ZKPs + TEEs (Privacy Boost) | 3-month PoC started July 8 | | KB Financial | Kaia | Not disclosed | Pilot completed May | | Deposit tokens (banks) | Project Hangang infrastructure | Banking-grade | H2 2026 scale tests |
No interoperability framework exists between these systems. If multiple won stablecoins launch on different chains without cross-chain settlement standards, Korea risks replicating domestically the fragmentation it is trying to escape internationally.
The economic pressure driving this race is measurable:
The FSC's January 2026 decision to allow corporate crypto investment (up to 5% of shareholder equity for listed firms) added institutional demand for on-chain won settlement that does not currently exist in production.
Korea's first multichain KRW stablecoin reached 1 billion won ($730,000) in daily volume by April 2026 — a negligible figure that underscores how early the market remains despite the frenetic pilot activity.
South Korea's won stablecoin landscape as of July 2026 is characterized by intense parallel activity with minimal coordination. The central bank, at least one provincial government, three major private-sector players, and nine commercial banks are all building or testing won-linked digital payment infrastructure on different blockchains with different privacy architectures.
The absence of the Digital Asset Basic Act means none of these initiatives can proceed to commercial deployment. The BOK's insistence on bank-majority consortium issuance directly conflicts with the ambitions of Toss and other fintechs. Until this question is resolved legislatively, Korea will continue accumulating proof-of-concept results without a path to production.
The economic case is clear: Korea has the users (16 million), the volume ($26 billion weekly), and the institutional demand (corporate crypto investment now legal). What it lacks is regulatory consensus on market structure. The country that banned corporate crypto holdings for nine years may now find that its stablecoin deadlock costs it more in capital outflows than any single pilot can recapture.
