Dunamu, the operator of South Korea's largest cryptocurrency exchange Upbit, announced a partnership with Visa on August 28 to develop payment and financial services built around stablecoins and artificial intelligence. The announcement came 48 hours after Visa signed a similar agreement with Shinhan Financial Group, another major South Korean financial institution. Two deals in two days, both focused on stablecoin infrastructure, both in the same country.
The geography here is not an accident. South Korea is home to one of the world's most active retail crypto markets, a regulatory framework that legitimized exchanges early, and a financial sector that watched the Kimchi Premium phenomenon prove domestic appetite for dollar-backed assets. Visa's move into the market signals a broader strategy: rather than launching its own stablecoin, the company is stitching together regional settlement infrastructure across multiple jurisdictions.
The Partnership Details
Dunamu CEO Oh Kyung-seok and Visa global president Oliver Jenkyn unveiled the roadmap at Visa's Global Market Support Center in San Francisco. The partnership pairs Dunamu's digital asset technology with Visa's global payments network to explore stablecoin-based payment and remittance services across major markets.
The business model being considered centers on Open Standard's proposed Open USD (OUSD), a dollar-backed stablecoin unveiled in June. According to reporting on the announcement, more than 140 companies have signed up to use OUSD, including Visa, Mastercard, Stripe, Coinbase, and BlackRock. The list reads like the institutional coalition required to move stablecoins from crypto-native rails into legacy payment infrastructure.
Visa's stablecoin settlement activity hit an annualized run rate of about $7 billion as of March 2026. That volume is modest compared to total global stablecoin transfer activity, but the number represents mainline adoption by a legacy payments network, not a crypto startup. Visa is not experimenting here. The company is building operational capacity.
Why South Korea
South Korea has the regulatory clarity and market liquidity that makes it a useful testbed for stablecoin payment infrastructure. The country's cryptocurrency exchanges operate under formal licensing from the Financial Services Commission. Upbit alone regularly processes billions in daily trading volume, much of it in won-USDT and won-USDC pairs.
The domestic demand for dollar-backed assets is structural. South Korea maintains capital controls that limit how much foreign currency residents can move offshore without approval. Stablecoins, when available through licensed exchanges like Upbit, offer a workaround that regulators have so far permitted within certain bounds. That regulatory tolerance, combined with high retail crypto adoption, creates the conditions Visa needs to test stablecoin settlement at scale.
Visa's decision to partner with both Dunamu and Shinhan Financial Group in the same week also points to a deliberate strategy of embedding stablecoin rails into both crypto-native platforms and traditional financial institutions simultaneously. One partnership gives access to retail crypto users. The other gives access to corporate banking customers. Together, they position Visa as the settlement layer connecting both.
The Broader Stablecoin Infrastructure Play
Visa's approach differs from competitors like Circle or Tether, which issue their own stablecoins and rely on third-party payment processors to distribute them. Visa is not issuing. The company is positioning itself as the infrastructure provider that connects multiple stablecoins to multiple payment endpoints across multiple jurisdictions. The South Korea partnerships are part of a broader 2026 pattern: Visa has signed bilateral stablecoin and AI-payments agreements with exchanges, banks, and payment firms across multiple countries while simultaneously joining multilateral, regulator-led frameworks.
This model makes more sense when you consider Visa's existing business. The company does not issue currency. It settles transactions denominated in hundreds of different currencies across thousands of institutions. Stablecoins, in this framework, are simply another asset class requiring settlement infrastructure. Visa's competitive advantage is not in creating new assets but in becoming the rails those assets move across.
The OUSD component is particularly telling. Open Standard's stablecoin has backing from both legacy finance (Visa, Mastercard) and crypto-native infrastructure (Coinbase, Stripe). If OUSD gains traction, it will likely do so because institutions trust the coalition backing it more than they trust algorithmic models or offshore issuers. Visa's participation legitimizes the product for banks hesitant to work directly with crypto companies.
What Adoption in South Korea Signals
Stablecoin adoption in South Korea will not look like stablecoin adoption in Argentina or Nigeria. The use case here is not about escaping hyperinflation or bypassing a collapsed banking system. South Korea has a stable currency and functional financial infrastructure. The demand for stablecoins in this context is driven by capital controls, cross-border payment friction, and the appeal of dollar-denominated savings in a market where the won fluctuates against major currencies.
That creates a different adoption pattern. In Argentina, stablecoins flow through peer-to-peer networks and informal remittance corridors. In South Korea, they flow through licensed exchanges integrated with KYC-compliant banking partners. Visa's model works better in the latter environment. The company is not chasing the informal economy. It is building infrastructure for the formal economy in jurisdictions where regulators permit stablecoin usage under supervision.
If the South Korea experiment succeeds, expect Visa to replicate the model in other high-regulation, high-liquidity markets. Japan, Singapore, and parts of Europe under MiCA all fit the profile. The countries where stablecoins matter most for financial inclusion will not see Visa partnerships, because those markets lack the regulatory frameworks Visa requires to operate. That does not make the South Korea partnerships irrelevant. It just means they are solving a different problem for a different set of users.
The Takeaway
Visa is not trying to replace Circle or Tether. The company is positioning itself as the settlement infrastructure that connects stablecoin issuers to legacy payment endpoints in jurisdictions where regulation permits it. South Korea is the testbed because the market has the liquidity, the regulatory clarity, and the institutional partnerships required to prove the model works at scale. If Dunamu and Shinhan can route meaningful stablecoin volume through Visa's rails in the next 12 months, expect similar partnerships to appear in other markets where formal finance and crypto infrastructure overlap. The competition here is not between stablecoins. It is between settlement layers. Visa is betting it can own that infrastructure without issuing a single token.
Frequently Asked Questions
Why did Visa partner with two South Korean companies in two days?
Visa signed partnerships with Dunamu (Upbit operator) and Shinhan Financial Group to position itself as stablecoin settlement infrastructure in South Korea. One partnership targets crypto-native retail users, the other corporate banking customers. Together they allow Visa to test stablecoin payment rails across both formal finance and crypto platforms in a regulated, high-liquidity market with strong retail crypto adoption.
What is Open USD and why does it matter for this partnership?
Open USD (OUSD) is a dollar-backed stablecoin proposed by Open Standard, backed by over 140 companies including Visa, Mastercard, Stripe, Coinbase, and BlackRock. The Dunamu-Visa partnership is considering business models involving OUSD. The coalition backing OUSD gives it institutional legitimacy that may appeal to banks hesitant to work with purely crypto-native stablecoin issuers like Circle or Tether.
Is Visa trying to compete with Circle or Tether?
No. Visa is not issuing its own stablecoin. The company is positioning itself as settlement infrastructure that connects existing stablecoin issuers to legacy payment endpoints across multiple jurisdictions. Visa's competitive advantage is in providing rails for stablecoin transactions, not in creating new stablecoins. The South Korea partnerships test whether Visa can own the settlement layer without issuing tokens.
Why is South Korea a good market for stablecoin infrastructure testing?
South Korea offers regulatory clarity, licensed exchanges, high retail crypto adoption, and structural demand for dollar-backed assets due to capital controls. Upbit processes billions in daily volume, much in won-stablecoin pairs. Regulators permit stablecoin usage under supervision, creating conditions for testing formal, KYC-compliant stablecoin payment infrastructure at scale. This differs from informal, peer-to-peer stablecoin adoption in unregulated markets.
What does Visa's $7 billion stablecoin settlement run rate indicate?
As of March 2026, Visa's stablecoin settlement activity reached about $7 billion annualized. While modest compared to total global stablecoin volume, this represents operational capacity from a legacy payments network, not experimental adoption. Visa is building real infrastructure for stablecoin transactions across its existing global network, signaling serious institutional commitment beyond proof-of-concept projects.
