How a Won Stablecoin Differs From a Bank Deposit
What a coin pegged to one won actually is, why full reserves are not the same thing as deposit insurance, why the Bank of Korea and the Financial Services Commission split over who may issue it, and where the legislation stands in September 2026.
Korean won stablecoins are suddenly everywhere in the news. Banks are forming consortia and filing trademarks, and a Digital Asset Basic Act is said to be arriving in the National Assembly any week now. What rarely gets explained is what the thing actually is. "A coin pegged to one won" describes a price, not a nature.
Here is the nature. A won stablecoin is not won. It is a private issuer's promise to give you won. Every question in the current Korean fight follows from that one line: who is allowed to make the promise, who pays when it breaks, and what keeps the issuer honest in the meantime.
What Holds the Price at One Won
There are three ways to hold a peg.
Asset-backed. The issuer sets aside real assets matching everything it issued and redeems at par on demand. Tether (USDT) and USDC work this way, and it is the only design any regulator is currently trying to legalize.
Crypto-overcollateralized. Volatile assets are locked up in excess of the face value, with automatic liquidation when collateral falls.
Algorithmic. Nothing is set aside; a supply-and-demand rule is supposed to do the work. Terra (UST) and LUNA went to effectively zero in a matter of days in May 2022, taking roughly 40 billion dollars with them. Since then, algorithmic designs have been excluded from serious regulatory discussion.
The market is overwhelmingly denominated in dollars. As of April 2026 the total market capitalization of dollar-pegged stablecoins sits in the 300 billion dollar range, with Tether holding roughly two thirds and USDC roughly a fifth. Half the motivation behind every national stablecoin project is right here. Once domestic payments and remittances start running on dollar-denominated tokens, monetary sovereignty stops being a technical question and becomes a market share question.
What Makes It Different From a Deposit
On screen, the number is indistinguishable from a bank balance. It is denominated in won, and it moves when you send it. The difference is in what holds the number up, and three things diverge.
First, how reserves work. Banks run on fractional reserves. They keep part of what they take in and lend the rest, expanding the money supply in the process. A stablecoin issuer cannot do that. The Korean draft would require reserves of at least 100 percent of the amount issued, held as bank deposits or government bonds. No credit is created, and the interest thrown off by those reserves becomes the issuer's main source of revenue.
Second, protection. Bank deposits in Korea are covered by the deposit insurance scheme up to 100 million won. A stablecoin has nothing equivalent. Instead the holder gets a redemption claim against the issuer, to be satisfied out of the segregated reserves if the issuer fails. A statutory insurance scheme and a claim on one company's assets are different species of safety net.
Third, interest. The draft settles on prohibiting interest payments to holders. Pay interest and the token starts competing with deposits, and money leaving banks means less funding for loans.
Put those three together and a stablecoin looks less like a deposit than like a banknote: a redemption claim issued against a reserve, structurally the same instrument banks printed during the gold era. It is the same shape ecash is rebuilding today on a bitcoin reserve.
The weakness of the banknote comes along with the shape. A 100 percent reserve does not make face value equal market value. When Silicon Valley Bank failed in March 2023, USDC traded down to 0.88 dollars. Not because the reserves were missing, but because part of them happened to be sitting inside that bank. What matters is not the size of the reserve but whether anyone can reach it during the hour it is needed. And redemption no longer means queuing at a teller window, which is why the Bank of Korea keeps pointing out that a coin run moves faster than a bank run.
The Real Dispute Is Issuance Rights, Not Technology
Agreement in Korea runs wider than the headlines suggest. Only licensees approved by the Financial Services Commission may issue. Reserves of at least 100 percent must be held in bank deposits or government bonds. No interest to holders. Redemption rights and disclosure obligations apply. None of that is seriously contested.
One question is stuck: who gets to issue.
The Bank of Korea's position is that issuance should run through a consortium in which banks hold at least 51 percent and control management. The Financial Services Commission and the industry want more room for non-banks, fintechs in particular. Minimum capital requirements are also unsettled, with proposals ranging from 500 million won to 25 billion won, and no one has fixed how much of an issuer an exchange may own. This disagreement is what kept the bill out of the Assembly for more than half a year.
The Bank of Korea's October 2025 report, "Key Issues and Policy Responses for Stablecoins," lists seven risks: depegging, coin runs, absence of deposit insurance, erosion of the separation between banking and commerce, circumvention of foreign exchange controls, weakened monetary policy transmission, and reduced bank intermediation. The list is long but converges on a single sentence. On what terms, and to whom, does the state delegate the function of issuing money.
It is worth saying plainly that this question has no clean answer. Restricting issuance to banks helps with reserve management and financial stability, but it is fair to wonder how energetically a bank will build a product that cannibalizes its own deposits. Opening it up brings competition and innovation at the cost of harder supervision. Both roads charge a toll, and choosing which toll to pay is what is actually heading to the Assembly.
Where the Law Stands in September 2026
Korea designed its digital asset legislation in two stages. Stage one, the Virtual Asset User Protection Act, took effect in July 2024 and covered custody of user assets and unfair trading. Stage two is the Digital Asset Basic Act, which governs issuance and distribution generally, and won stablecoins belong to it.
As of 9 September 2026, the government bill has not been submitted. The plan under discussion is for the chair of the National Policy Committee to introduce a consolidated version reflecting the government's input during September, possibly before the Chuseok holiday. Industry observers think that missing September means missing the year, because October brings the parliamentary audit and November and December are consumed by budget review.
Passage would not be the end of it either. For stablecoins to actually clear payments and remittances, the Electronic Financial Transactions Act, the Act on Reporting and Using Specified Financial Transaction Information, and the Foreign Exchange Transactions Act all have to be amended. The last one in particular was written without any conception of a won-denominated token crossing a border.
Meanwhile the banks moved before the law did. Several financial holding groups are discussing joint-issuance consortia, and at least one bank has completed a trademark filing and technical trials for remittance. They are positioning for the possibility that issuance ends up bank-centric.
All of this is an ongoing negotiation rather than settled law. Every requirement and figure in this article can change in committee.
Where Other Jurisdictions Landed
The United States set its framework with the GENIUS Act, enacted in July 2025. Banks and non-banks may both issue payment stablecoins subject to regulatory approval, and reserves are confined to cash and short-dated government paper. The direction is the interesting part: the United States drew a line against a retail CBDC issued by the central bank and chose instead to pull privately issued stablecoins inside the regulatory perimeter.
The EU regulates under MiCA, splitting asset-referenced tokens from e-money tokens and restricting issuance to authorized institutions. National transitional grandfathering ended on 1 July 2026.
Japan, under the revised Payment Services Act that took effect in June 2023, limits stablecoin issuance to banks, trust companies, and licensed funds transfer operators. In confining issuance to licensed institutions, it sits closer to what the Bank of Korea is asking for.
Read side by side, the three make Korea's remaining dispute easier to see. Licensing and full reserves are close to an international standard by now. What is distinctly Korean is how much of that licence goes to banks.
What Actually Changes for Users
The upside is real: transfers that do not care about banking hours, payments with conditions written into code, and cross-border remittances that take minutes instead of days.
What does not change is equally real.
The properties of the won come along unchanged. The token loses purchasing power at exactly the rate the won loses it. Debasement runs at the same speed whether the claim is printed on paper or recorded on a ledger.
Freezing and seizure come along too. An issuer can freeze the balance at a given address, and dollar stablecoin issuers already do so at the request of law enforcement. A licensed issuer complying with domestic legal orders is not an edge case; it is part of the design.
So is identity verification. As long as won enters and leaves through an exchange, KYC and the travel rule apply exactly as they do today.
A won stablecoin changes how won moves. It does not change what won is. Missing that distinction is how people end up expecting a coin to be free of the rules that govern the currency it represents.
Set Beside Bitcoin
Two things living in the same wallet are not therefore the same kind of thing.
A stablecoin has an issuer. Its value depends on whether that issuer really holds the reserves, obeys the rules, and withstands pressure. It is a well-built payment rail, but there is always a counterparty you have to trust.
Bitcoin has no issuer. That is why its price moves, and that is why no one can freeze it. The stability the stablecoin gained and the permissionlessness bitcoin gained are two different choices made at the same fork.
Which is also where their uses part. If next month's rent has to arrive tonight, the stablecoin is the better tool. If the money has to still be there in ten years, there is little reason to leave it with someone who can issue and freeze it. That second case is where self-custody is the answer.
Summing Up
A won stablecoin is not a digital copy of the won. It is a licensed private promise to deliver won. Unlike a deposit it must be fully reserved, unlike a deposit it carries no state insurance, and like a banknote it requires trusting its issuer.
As of September 2026 the open question is not technical but jurisdictional. Does the power to issue money stay tied to banks, or does it open up under licence? That decision shapes what won will look like as it circulates in Korea for years afterward.
And either way, one thing holds. Money with an issuer follows its issuer's circumstances. Where that does not matter, it is a convenient tool. Where it does, it is worth remembering why money without an issuer was built in the first place.
