South Korea Wants a Won Stablecoin. Its Firms Chose Dollars.
South Korea is building a won stablecoin and restricting USDC and USDT, yet its biggest firms just chose the dollar. What the standoff means for merchants.
On June 30, 2026, thirteen of South Korea's largest companies, including Samsung Electronics, Shinhan Financial Group, Hyundai Card, and K bank, joined the consortium behind Open USD, a dollar-pegged stablecoin. That is a striking choice for a country that has spent the year trying to build a won-based stablecoin of its own. South Korea wants a domestic digital currency, yet its biggest firms just aligned with the dollar.
The reason is not that Korea changed its mind. It is that the won stablecoin is stuck, held up by a fight over who should be allowed to issue it, while the rules for everyone else keep tightening. For any merchant that sells to Korean customers or operates in the country, this decides which stablecoins will actually be usable there.
This guide explains what Korea is trying to do, why it has stalled, why regulators are moving against dollar stablecoins, and what the whole standoff means for merchants.
What to Know
- South Korea is working on a framework for a won-pegged stablecoin, but the legislation has stalled over a dispute about who is allowed to issue one.
- The Bank of Korea wants issuance limited to consortiums that are majority-owned by banks. Other regulators want to open it to fintech firms too. That disagreement is the main blockage.
- Three bills are under review in the National Assembly, each requiring a minimum capital of about 5 billion won, roughly 3.4 million US dollars, for an issuer.
- Separately, the Financial Services Commission has moved to restrict corporate use of dollar stablecoins like USDC and USDT, tied to foreign-exchange rules that do not yet recognize stablecoins for cross-border payments.
- While the won coin waits, Korean giants have hedged toward the dollar. Thirteen major firms joined the Open USD consortium on June 30.
- For merchants, the practical path in Korea runs through card networks and licensed local entities today, with the stablecoin mix still being decided by regulators.
Why South Korea wants its own stablecoin
Start with the motive, because it explains everything that follows. A country's currency is one of the main levers it controls. When people hold and spend won, the money stays inside the Korean banking system, the central bank can steer it, and the government can see and tax it.
Dollar stablecoins quietly undercut all of that. Today USDT and USDC together make up more than 80 percent of the stablecoin market. If Korean businesses and consumers start holding dollars on a blockchain instead of won in a bank, money drifts out of the domestic system and toward the dollar. Economists call this dollarization, and for a mid-sized open economy it is a real concern, not a theoretical one.
So Korea's goal is straightforward. It wants a won stablecoin that captures the speed and programmability of the technology while keeping the value denominated in its own currency and inside its own regulated institutions. This is the same instinct behind Europe's push for euro stablecoins under MiCA, which we covered in our euro stablecoins guide. The difference is that Korea has not managed to agree on how.
Why the won stablecoin is stuck
The delay is not technical. It is a fight over who gets to control the money, and that is worth understanding because it is the real story.
The Bank of Korea argues that only bank-led consortiums, majority-owned at 51 percent or more by banks, should be allowed to issue a won stablecoin. Its reasoning is that banks are the entities equipped to guarantee stability, manage foreign-exchange risk, and enforce anti-money-laundering controls. In that view, a stablecoin is close enough to money that only banks should mint it.
Other regulators, led by the Financial Services Commission, take a more open line. They warn that a rigid bank-ownership rule would suppress competition and lock out the fintech firms that actually have the technical skill to build the infrastructure. Three separate bills are now under review in the National Assembly, each setting a minimum issuer capital of around 5 billion won, but they diverge on the core questions, including who can issue and whether holders can be paid interest.
Until that disagreement resolves, nothing ships. A stablecoin regime is really a decision about who holds the keys to a new form of money, and neither the central bank nor the fintech-friendly regulators want to concede that ground. So the won coin sits in committee while the market moves on without it.
Why Korea is restricting USDC and USDT
While the domestic coin waits, regulators have moved in the other direction on the dollar ones. The Financial Services Commission has reportedly been preparing corporate digital-asset guidelines that would exclude dollar stablecoins such as USDC and USDT from the list of assets Korean companies can freely use.
The stated reason is legal rather than ideological. South Korea's Foreign Exchange Transactions Act does not currently recognize stablecoins as valid instruments for cross-border payments, so a company moving value in USDC sits in a gray zone under existing foreign-exchange law. Under the draft approach, a foreign-issued stablecoin would be permitted in Korea only if the issuer sets up a licensed local branch or subsidiary, bringing it inside Korean supervision.
Put the two moves together and the strategy is clear. Korea wants to slow the spread of dollar stablecoins among its businesses while it builds a won alternative it can regulate directly. The problem is what happens in the gap between those two things.
The twist that gives the game away
Here is the part that reveals the flaw in the plan. Restriction and delay were meant to protect the won. Instead they are pushing Korea's own champions toward the dollar.
The won stablecoin is stalled and its timeline is uncertain. Dollar stablecoins are being restricted but still dominate the global market and actually work at scale today. Faced with that gap, Korea's largest firms did the rational thing. Rather than wait for a domestic coin that may be a year or more away, thirteen of them, including Samsung Electronics, Shinhan Financial Group, Hanwha Life, and several major card companies, joined the Open USD consortium on June 30 to secure a position in a dollar network now. We explained what Open USD is and how its economics work in our Open USD guide.
This is the first-principles lesson. A business cannot run on a currency that does not exist yet. When a government tries to protect its currency by moving slowly and restricting the alternative, it does not stop the demand for fast digital dollars. It just delays the point at which its own companies switch. The attempt to prevent dollarization through caution is, in the short run, accelerating it.
Won stablecoin, dollar stablecoins, and Open USD in Korea
The table compares the three options from the point of view of a business operating in or selling to Korea, as things stand.
| Factor | Won stablecoin (planned) | USDC and USDT | Open USD (OUSD) |
|---|---|---|---|
| Availability today | Not live, legislation stalled | Live, but corporate use being restricted | Launching in 2026, Korean firms joined |
| Denomination | Korean won | US dollar | US dollar |
| Regulatory standing in Korea | Being written, bank-led likely | Gray zone under FX law | Dollar coin, same FX questions apply |
| Who is behind it | Bank consortium, contested | Circle and Tether | 140-plus global firms, 13 Korean |
What this means for merchants
If you sell to Korean customers or run operations there, a few things follow from all of this. First, do not assume USDC or USDT will remain freely usable for Korean corporate flows. The direction of travel is toward restriction, and a business that hard-wires a single dollar stablecoin into its Korea operations is building on ground the regulator is actively reshaping.
Second, do not wait for the won stablecoin to plan around it either. Its timeline depends on a political fight with no clear end date. Planning a launch around a coin that does not exist is as risky as ignoring the rules that do.
Third, the practical rails in Korea today still run through cards and licensed local entities. Korean card firms have already tested letting foreign visitors spend stablecoins with local merchants by routing them through the existing card authorization layer, and terminal networks are expanding to bring stablecoin settlement into offline retail. For now, that hybrid path is where real Korean merchant activity sits, and it is covered by the infrastructure merchants already understand from our stablecoin payments business guide.
Where AIO fits
The common thread across a market this unsettled is that you cannot bet everything on one token or one jurisdiction's timeline. AIO is a non-custodial crypto payment gateway built for exactly that uncertainty. It accepts stablecoin payments across multiple chains through a single API, so which stablecoin clears is a configuration choice rather than a fixed dependency. If Korea restricts one dollar coin, promotes a won coin later, or a merchant needs to accept whichever token a customer actually holds, the gateway adapts without a rebuild of your payment stack.
Because AIO is non-custodial, you keep control of your funds rather than parking them with an issuer or platform whose standing in a given country can change with a new rule, which is the point of our explainer on non-custodial gateways. The pricing stays merchant-friendly at 0.3 percent on pay-ins and 0 percent on payouts, with AIO covering the network gas. When a market is still deciding which stablecoins are allowed, the safest position is to be able to accept the ones that are, and to switch when the rules do.
Frequently asked questions
Does South Korea have a won stablecoin yet?
Not yet. Legislation is under review in the National Assembly, but it has stalled over a dispute about who can issue one. The Bank of Korea wants issuance limited to bank-majority consortiums, while other regulators want to allow fintech firms too. No won stablecoin has launched.
Are USDC and USDT banned in South Korea?
Not banned, but restricted for corporate use. The Financial Services Commission has reportedly moved to exclude dollar stablecoins from the assets Korean companies can freely use, because foreign-exchange law does not yet recognize stablecoins for cross-border payments. Foreign issuers may need a licensed local entity to operate.
Why did Korean companies join Open USD if Korea wants a won coin?
Because the won coin is delayed and dollar stablecoins still dominate the market and work today. Rather than wait, thirteen major Korean firms joined the Open USD consortium on June 30, 2026 to secure a position in a working dollar network now.
Can a merchant accept stablecoin payments in Korea today?
In practice, mostly through card rails and licensed local entities rather than direct token acceptance. Korean card firms have piloted letting visitors spend stablecoins with local merchants through the card settlement layer, and terminal networks are expanding. Direct rules are still being written.
What should a merchant selling to Korea do now?
Avoid hard-wiring a single stablecoin, since the approved set is changing. Use infrastructure that can accept multiple stablecoins across chains and switch as the rules settle, rather than betting on either the restricted dollar coins or the delayed won coin.
Korea's standoff will resolve eventually, but which stablecoins a merchant can use there is being decided right now, and it is moving. If you want to keep selling into a market whose rules are still being written, a non-custodial, multi-chain gateway is the way to stay flexible.
