South Korea's largest financial conglomerates moved aggressively in the first half of 2026 to acquire crypto infrastructure, form blockchain partnerships, and pilot stablecoin payments, all before the country's Digital Asset Basic Act has cleared the National Assembly. With roughly 18 million Koreans holding retail crypto accounts across all exchanges and wallets (a broader figure than the 13.26 million cumulative users recorded by Upbit alone) and a domestic regulatory framework still unresolved, the country's banks are choosing to build first and wait for the rules second.

The wave of activity follows a significant policy shift: South Korea lifted its nine-year ban on corporate crypto holdings in early 2026, and listed companies can now allocate up to 5% of annual equity capital into digital assets. That change provided the enabling conditions for the institutional moves now reshaping the sector.

The opening move came from Hana Financial Group, which paid 1 trillion won (approximately $670 million) for a 6.55% stake in Dunamu, the company behind Upbit, South Korea's largest crypto exchange. The purchase makes Hana Dunamu's fourth-largest shareholder, behind founder Song Chi-hyung (25.51%), Vice Chair Kim Hyoung-nyon (13.1%), and Woori Technology (7.2%). The presence of Woori Technology on the cap table is notable: it means a second major financial group already held a larger stake before Hana's entry. Hana Chairman Ham Young-joo was direct about the group's ambitions: "Simply issuing coins will not create opportunities. We need to create new rules and lead the market."

Competitors are not waiting to respond. KB Financial Group completed a proof-of-concept stablecoin pilot on the Kaia blockchain alongside payment processor KG Inicis and Open Asset. The tests included QR-code payments at cafes and, more significantly, a remittance transfer to Vietnam that completed in under three minutes at 87% lower cost than conventional transfers via SWIFT or hawala networks. That figure matters beyond Korea: the country now hosts 1.1 million foreign workers, many from Vietnam, Bangladesh, Nepal, Sri Lanka, Indonesia, and the Philippines, where SWIFT-based remittances and hawala channels remain expensive and slow.

Shinhan Financial Group, meanwhile, signed a memorandum of understanding with the Solana Foundation and is building a stablecoin payment layer that connects to consumer wallets such as MetaMask and Phantom. Shinhan is pointing to its 14.5 million credit card members as a ready distribution base. Also active on Solana is KRWQ, a won-pegged stablecoin targeting roughly $40 billion in daily KRW spot volume and $60 billion in KRW offshore non-deliverable forward markets, a concurrent development that underscores the chain's growing centrality to Korean digital finance.

Separately, K Bank, which serves as Upbit's exclusive banking partner, is running a second phase of cross-border transfer tests with Ripple, targeting corridors to the UAE and Thailand. Woori Financial Group is pursuing a B2B settlement and consortium wallet strategy, a direction its Vice President Ok Il-jin has outlined publicly. BC Card is piloting a stablecoin-backed prepaid card for overseas visitors. And eight major commercial banks are collaborating on a shared KRW-pegged stablecoin consortium, a detail that reframes the competitive picture: alongside the bank-by-bank moves, a significant portion of the industry is also working collectively toward shared infrastructure. In the asset management sector, Mirae Asset has acquired a stake in Korbit, and Korea Investment and Securities has reviewed a position in Coinone.

The urgency behind all of this activity is rooted in a specific regulatory gap. South Korea's Digital Asset Basic Act, intended to be the country's first comprehensive crypto law, stalled past its Q1 2026 target because two regulators cannot agree on who should be allowed to issue a won-pegged stablecoin. The Bank of Korea (BOK) argues that only bank-led groups holding at least a 51% ownership stake can legitimately operate as issuers, citing existing compliance infrastructure. The Financial Services Commission pushes back, warning that a majority-bank requirement would freeze out fintech firms and push innovation to faster-moving jurisdictions like Singapore.

The European Union's MiCA framework offers a relevant comparison: of the 15 regulated stablecoin issuers under MiCA, 14 are electronic money institutions rather than banks. Ahn Do-geol, Task Force Secretary General of the Democratic Party of Korea, speaking on the BOK's proposed structure, said: "With this governance model, it will be difficult to achieve the network effects and technological breakthroughs that stablecoins can deliver."

New BOK Governor Shin Hyun-song has not helped clarify the situation. During his confirmation hearings he described stablecoins as potentially playing a "supplementary and competitive" role alongside central bank digital currencies and deposit tokens. His inaugural address made no mention of stablecoins at all, a silence industry observers interpreted as the BOK protecting ground for its own retail CBDC initiative, Project Hangang, and commercial bank deposit tokens.

On-chain data offers a useful reality check on one piece of this infrastructure. Kaia, the blockchain KB Financial used for its pilot and the chain formed by merging Kakao's Klaytn with LINE's Finschia, currently holds approximately $12.5 million in total value locked, down sharply from a peak near $104 million in August 2025, and ranks around 65th globally for TVL. The picture is more nuanced at the stablecoin layer: Kaia's stablecoin TVL stands at approximately $41 million with daily volume around $13.9 million, figures that are disproportionately large relative to overall TVL and directly relevant to the payments use case being built on the chain. Institutional credibility has not yet translated into broad user adoption, and that gap may matter when regulators begin evaluating which chains meet the standards for licensed payment infrastructure.

The stakes of Korea's stablecoin debate extend well beyond its borders. Asia already accounts for roughly 60% of real-use stablecoin payment volume globally, yet nearly 99% of all stablecoins are pegged to the US dollar. President Lee Jae-myung has explicitly framed KRW stablecoin development as part of a broader goal to reduce Korean dependence on dollar-denominated settlement. Regional peers are already further along: Japan launched JPYC in October 2025 as the first yen stablecoin regulated under the Financial Services Agency, and Singapore's StraitsX has recorded $1.8 billion in cumulative volume. Both benchmarks illustrate how much ground Korea's stalled legislation has already ceded to faster-moving neighbors. Foreign issuers are watching closely as well: Circle and Tether have filed Korean trademarks and are building local partnerships, and regulatory signals indicate that foreign-issued stablecoins will require domestic subsidiaries to operate legally in Korea for payments purposes. That requirement carries direct implications for projects across Africa and South Asia that rely heavily on USDT for cross-border settlement.

A won-backed stablecoin operating at scale would offer a technical template for other mid-sized economies, including India, Nigeria, Bangladesh, and Kenya, all of which face similar choices about whether to let central banks control stablecoin rails or permit private issuers within a reserve-backed framework.

Prof. Hwang Suk-jin, commenting on the banks' pre-regulatory positioning, put the situation plainly: "Banks cannot just sit back because there is no law yet." The Digital Asset Basic Act has no confirmed passage date. Korean financial groups have decided that waiting is the one option they cannot afford.
