1. South Korea stablecoin regulation: stablecoins as a means of payment
South Korea is working to bring stablecoins into its foreign exchange rules by adding them to the definition of a means of payment under the Foreign Exchange Transactions Act. The change would place dollar-pegged tokens in the same legal category as banknotes and coins, and it is aimed at cross-border flows that have so far moved with little oversight. The effort has been under way since a lawmaker first proposed the amendment in October 2025.
Supporters of the change point to three concerns tied to dollar stablecoins: unregulated cross-border transactions, money laundering and tax evasion. Dollar-pegged tokens are popular with South Korean users, which gives the concerns practical weight.
2. What is the Foreign Exchange Transactions Act?
The Foreign Exchange Transactions Act is the law that governs how money, securities and other assets move across South Korea's borders. It sets out which transactions must be reported, which must be registered and which instruments count as means of payment. Authorities use it to monitor capital flows and to keep track of currency exposure.
Because the act was written around conventional currencies and instruments, a token that holds a steady dollar value and moves freely over public networks does not fit neatly into its categories. Classifying stablecoins as a means of payment would remove that ambiguity by stating that, for the purposes of foreign exchange oversight, they are treated like other payment instruments.
That legal status matters because the obligations attached to a means of payment follow from it. Once a token is covered by the definition, the reporting and supervisory tools the act already contains can be applied to its cross-border use, rather than having to be rebuilt for each new kind of asset.
3. Why the foreign exchange risk is the central concern
The core issue is foreign exchange risk. A large volume of dollar-pegged tokens moving in and out of the country could act as a parallel channel for sending money abroad, outside the monitoring that the act was designed to provide. Stablecoins are issued abroad, held on global networks and can be transferred in minutes, which makes them an efficient route for value that regulators would otherwise be able to see.
The Bank of Korea has long pushed for an overhaul of the foreign exchange rules, with particular emphasis on tighter control of dollar stablecoin outflows. For a central bank, large and unmonitored movements into dollar assets can complicate the management of the exchange rate and the measurement of capital flows.
The same features that make stablecoins attractive to users, speed, low cost and a stable value, are the ones that raise supervisory questions. Money laundering and tax evasion concerns follow from the difficulty of tracing who moved value, where it went and whether the proper reports were made.
4. How did the legislative effort develop?
The legislative track began in October 2025, when a lawmaker announced plans to propose a bill classifying stablecoins as a legal means of payment under the Foreign Exchange Transactions Act. The stated aim was to reduce the risks created by the unregulated circulation of dollar stablecoins.
A separate amendment passed the National Assembly on May 7, 2026. It brought cross-border remittances made with virtual assets under the act. Reports on that amendment say that the core rules were left to a presidential decree, which means much of the practical detail depends on rules still to be set by the government.
In July 2026, the Ministry of Economy and Finance said it would draft the Digital Asset Basic Act this year as a second phase of legislation, and that officials were reviewing ways to bring cross-border stablecoin transactions into the formal regulatory system. The foreign exchange amendments are therefore one part of a larger effort rather than a stand-alone measure.
5. What is the Digital Asset Basic Act?
The Digital Asset Basic Act is the broader piece of legislation intended to set out a framework for digital assets in South Korea, including stablecoins. It was first submitted in 2025 and has since faced delays, and the details remain under debate.
Reports on a draft of the act, circulated by the ruling Democratic Party, said stablecoins used in cross-border transactions would be classified as a means of payment under the Foreign Exchange Transactions Act. That would align the broader digital asset law with the foreign exchange amendment, so that the two measures describe the same instruments in the same way.
A point that remains open is how stablecoin issuance itself will be regulated. South Korea does not have a dedicated licensing regime for stablecoin issuers, and policy discussions have centered on partnerships between banks and financial technology companies, including who should be allowed to issue stablecoins and what capital requirements they should meet.
6. What a means-of-payment label does and does not do
Calling a token a means of payment is a classification, not an endorsement. It tells the authorities and the market which rulebook applies, and it allows existing foreign exchange reporting to reach transactions that were previously difficult to place within the law. It does not by itself decide who may issue a stablecoin, how reserves must be held or what disclosures holders are owed. Those matters belong to the wider framework still being drafted.
The distinction explains why the amendment and the Digital Asset Basic Act are discussed together. The first addresses how stablecoins are treated when they cross the border, while the second is meant to address the market structure around them. A gap between the two, such as a payment label without an issuer regime, would leave part of the picture unresolved.
For companies planning stablecoin products in South Korea, the sequence of these decisions matters. Firms cannot finalize their compliance plans until the presidential decree and the issuer rules are known, and uncertainty over either can delay product launches and partnership agreements.
7. The trade-offs facing regulators
Regulators face a balance between control and usefulness. Tight foreign exchange oversight can reduce the risk of unmonitored capital outflows, money laundering and tax evasion, but heavy requirements can also push users toward offshore platforms that sit outside the system altogether. Rules that are too burdensome could therefore defeat the purpose of bringing activity into view.
At the same time, stablecoins are increasingly used for payments and settlement, and many governments are trying to capture the efficiency benefits while limiting the risks. South Korea's approach, which starts from the foreign exchange angle, reflects the importance of capital flow management for an economy with a large trade sector and a currency that is sensitive to dollar movements.
How the balance is struck will become clearer as the decree and the broader act take shape. The government has said it is reviewing ways to bring cross-border stablecoin transactions into the formal regulatory system, which indicates that the goal is integration rather than prohibition.
8. Who is affected by the change?
The most direct effect would fall on businesses that handle cross-border transfers of virtual assets. If stablecoins are a recognized means of payment, those businesses would operate under the foreign exchange oversight that applies to other payment instruments, with the compliance duties that implies.
Ordinary users are likely to see more scrutiny of transfers that cross the border, since intermediaries that are known to the authorities and accountable to them would be the channel for such flows. Users who move dollar tokens to or from overseas platforms could expect more reporting and identification requirements than before.
Smaller operators may face higher costs of entry. Building the compliance systems needed to meet registration and reporting rules requires investment, and that burden weighs more heavily on small firms than on large banks and established exchanges.
9. Why bank and fintech partnerships are central to the debate
The question of who may issue a won-denominated or foreign-currency-backed stablecoin is closely linked to the foreign exchange rules. Banks already operate inside the supervisory system, hold deposits and are familiar with capital requirements. Financial technology firms bring product design and customer reach but sit further from traditional supervision.
Policy discussions have therefore focused on arrangements in which banks and fintech companies work together, with the bank providing the regulated foundation and the technology partner providing the user-facing product. How much capital such an issuer should hold, and who bears the risk if reserves fall short, are among the questions still being worked out.
These decisions will shape how much of the stablecoin market in South Korea is conducted by domestic institutions and how much remains with foreign issuers, which is the very issue that prompted the foreign exchange amendment.
10. What comes next for stablecoin rules in South Korea?
Officials have signaled that the stablecoin amendments are being advanced quickly, and that the aim is to have adequate regulatory measures in place by the end of 2026. The government has said it intends to draft the Digital Asset Basic Act within the year, so legislative action on the broader framework is the next step to follow.
Observers will be watching two things: the content of the presidential decree that fills in the rules left open by the May amendment, and the shape of the Digital Asset Basic Act, including whether it sets licensing and capital requirements for stablecoin issuers. Whether the end-of-year target is met will indicate how seriously Seoul treats stablecoins as a foreign exchange matter.
Until those pieces are in place, the practical position of stablecoins in South Korea remains in transition: the direction of policy is clear, but the specific obligations on users, intermediaries and issuers are still being defined by the government and the National Assembly.
