South Korea Tightens Stablecoin Transfer Rules as Broader Payment Law Takes Shape

A December deadline for crypto transfers

South Korea is preparing to bring cryptocurrency transfers under closer foreign exchange supervision from December 3, 2026, while developing a separate proposal to regulate stablecoins as payment instruments. The immediate change concerns businesses moving digital assets between South Korea and overseas: they will face registration, reporting and inspection requirements.

The National Assembly passed the Foreign Exchange Transactions Act amendment on May 7. An enforcement decree proposed on October 7 would extend monitoring to transfers involving personal wallets, as well as activities such as custody and brokerage. Businesses operating without the required registration could face criminal penalties, including up to three years in prison.

For people holding Tether's USDT or Circle's USDC, the practical consequence is greater scrutiny of the services through which tokens move. South Korea is creating a framework to track digital money crossing its financial borders. Approval for stablecoin issuers and rules governing their products belong to another legislative process.

The Bank of Korea has said it plans to prepare a further foreign exchange amendment with the government during 2026 to regulate stablecoins as payment instruments. Meanwhile, Financial Services Commission Chairman Lee Eog-weon says consultations on the broader Digital Asset Basic Act are nearing completion.

Three policy tracks therefore matter: a transfer registration law scheduled to take effect in December, proposed operating rules explaining its reach, and wider legislation on digital assets and stablecoin issuance. Their different stages determine what businesses must prepare for now and what users still need lawmakers to settle.

What the passed law changes

Kim & Chang's analysis of the amendment describes its main purpose as building a monitoring system for international capital movements involving virtual assets. The legislation creates a registered category of virtual asset transfer business within the foreign exchange framework.

Businesses seeking registration must first have completed the virtual asset business filing required under the Act on Reporting and Using Specified Financial Transaction Information. They must also connect their computer systems to the Bank of Korea, the institution responsible for concentrating foreign exchange information, and satisfy prescribed requirements for facilities and specialist personnel.

Registered operators will face obligations comparable to those imposed on institutions handling foreign exchange business. They must respond to requests for information and inspections, and provide advance notification when changing registration details or closing the business.

The law also creates routes for sharing transfer information. The finance ministry may provide data directly, or through institutions including the Bank of Korea, to the Financial Services Commission, National Tax Service, Korea Customs Service, Financial Supervisory Service and Export-Import Bank of Korea.

For a transfer operator, registration therefore means an ongoing relationship with supervisors. Connecting to the reporting network, maintaining records and answering inspections become part of running the service.

Why personal wallets are included

The October 7 draft enforcement decree gives the transfer regime a broad proposed reach. Alongside buying, selling and exchanging digital assets, it includes custody, management, brokerage, arranging transactions and acting on behalf of customers.

Transfers between a virtual asset service provider and a personal wallet would also fall within its scope. A personal wallet, sometimes called an unhosted wallet, lets someone control crypto assets without an exchange holding them on the person's behalf.

That feature matters because a wallet address does not carry a reliable physical location. Once assets leave a regulated service, authorities can find it harder to determine who controls them or whether the economic transfer has crossed a national border. The proposal treats relevant transfers involving personal wallets as producing effects comparable to international movements.

The registration duties attach to businesses performing covered services. An exchange customer withdrawing tokens to a personal wallet could therefore encounter additional checks and reporting through the service handling the withdrawal.

The proposed decree does not impose a separate minimum capital requirement on virtual asset transfer businesses. Operators would still need the existing financial information law filing, a connection to the foreign exchange network and the necessary operational arrangements. Building those systems and staffing them could be a substantial task for smaller firms.

Why Seoul is using foreign exchange law

The Bank of Korea's foreign exchange legislation guide explains that the Foreign Exchange Transactions Act governs foreign exchange operations, payments and receipts, certain capital movements, and the responsibilities of institutions handling that business.

The same guide distinguishes money movements from goods movements. The International Trade Act primarily governs commodity flows, while the Foreign Investment Promotion Act concerns foreign investment and technology entering Korea. Foreign exchange law is the framework for following the money.

Stablecoins are digital tokens designed to track the value of another asset, commonly the US dollar. USDT and USDC aim to maintain a value of one dollar per token. Their ability to move between digital addresses allows payments and international transfers to take place outside conventional bank transfer channels.

The Bank of Korea has identified money laundering and illicit international transactions as concerns, including risks associated with global digital asset exchanges, personal wallets and mixers. A mixer combines or redirects transactions to make the connection between a sender and recipient harder to follow.

The central bank is preparing a digital asset monitoring system that includes reporting through the foreign exchange information network. It also wants international cooperation against illegal transactions and coordination among Korean authorities during gaps between existing rules and new legislation.

Payment status and issuer approval follow different tracks

The Bank of Korea's plan to regulate stablecoins as payment instruments is a further legislative step. In its response to requests from the 2025 parliamentary audit, the central bank said it was discussing regulation of international digital asset transactions with the government and planned to prepare a foreign exchange amendment during 2026.

That timetable is a commitment to prepare legislation within the year. Passage, detailed obligations and implementation would depend on the resulting bill and the legislative process. The December 3 commencement date belongs to the transfer registration amendment already passed.

Representative Park Sung-hoon had announced a proposal on October 28, 2025, to classify stablecoins as means of payment under foreign exchange law. The current central bank initiative continues the effort to bring these tokens into rules governing international money movements.

The Digital Asset Basic Act addresses a wider set of questions, including exchange licensing, stablecoin issuance and clearer legal definitions. On October 22, FSC Chairman Lee said government consultations were nearing completion and that the government would work to introduce the bill as soon as possible.

For users and businesses, the practical division is straightforward: transfer registration governs the service moving the assets, while issuance rules govern the organisation creating the tokens and the conditions under which it may operate. A stablecoin payment framework would also need to set out how those tokens can be used within the regulated system.

Which deadlines matter?

The transfer rules are approaching implementation while the broader digital asset framework remains in consultation. The main dates show how the two processes have developed:

• October 28, 2025: Representative Park Sung-hoon announced a proposal to classify stablecoins as payment instruments under foreign exchange law.
• May 7, 2026: The National Assembly passed the amendment creating the virtual asset transfer registration regime.
• June 2, 2026: The amendment was promulgated.
• October 7, 2026: The finance ministry published the proposed enforcement decree.
• October 22, 2026: FSC Chairman Lee said consultations on the Digital Asset Basic Act were nearing completion.
• October 26, 2026: Public comments on the proposed enforcement decree were due.
• December 3, 2026: The passed amendment is scheduled to take effect, with the proposed decree intended to begin alongside it.
• June 30, 2027: Certain existing foreign exchange operators would have to meet updated registration conditions under proposed transitional arrangements.

The June deadline requires particular care. It applies to qualifying existing currency exchange, small overseas remittance and other specialised foreign exchange businesses. The draft provides no separate transitional provision for the new virtual asset transfer category.

Crypto businesses therefore need to prepare around the December commencement. Some operational details, including application documents, personnel training and information technology standards, are to be set through subsequent regulations and ministry notices.

A wider overhaul of remittances and currency exchange

The amendment also reorganises specialised foreign exchange services into general currency exchange and overseas payment and settlement businesses. The proposed decree divides the latter into six types, bringing small overseas remittances and other specialised services into a common structure.

Small overseas remittance businesses would retain a minimum capital requirement of 1 billion won. The proposal requires at least two qualified specialists, rising to five for operators combining three or more business types. Businesses carrying out multiple types must register each type separately.

The finance ministry's figures help explain the parallel focus on currency exchange firms. Of 1,346 operators reporting results for the first half of 2026, 581 recorded no purchases of foreign currency. That is about 43%, calculated from those two figures.

The proposed rules introduce capital and management eligibility conditions for currency exchange operators. They also strengthen sanctions for businesses operating outside their registered scope, including the possibility of registration cancellation after a single violation.

Customers sending money overseas could consequently see changes extending beyond crypto platforms. Remittance companies, currency exchange businesses and electronic payment providers will be adapting to revised staffing, registration and customer protection requirements.

Stronger penalties and broader inspections

The passed law strengthens punishment for certain payment procedure violations. Conduct previously subject to an administrative fine of up to 50 million won may bring up to one year in prison or a criminal fine of up to 100 million won when it is intended to obtain an improper property or financial benefit for the offender or another person.

The intent requirement is central to that stronger sanction. Businesses arranging currency exchange, remittances or movements of property abroad need to check both the applicable procedures and the purpose of the transaction.

The proposed decree would also allow customs officials investigating trade transactions to continue examining related service or capital transaction violations discovered during their inspections. This creates a more connected inspection process for companies whose imports, exports, overseas investments and borrowing overlap.

Other parts of the amendment clarify that expenses needed to maintain overseas branches fall within capital transactions. They also revise procedures for the foreign exchange stability levy: financial companies may object within 30 days of receiving notice, and the ministry must respond within 14 days of receiving the objection. The levy would have a term set by presidential decree of no more than 10 years.

Crypto taxation adds another approaching deadline

South Korea's proposed crypto tax is targeted to start on January 1, 2027, after three delays. That puts taxation close behind the December transfer rules, while lawmakers are still working on the broader legal framework for digital assets.

Public petitions have pressed for a different timetable. A repeal petition reached the 50,000 signatures needed to trigger legislative review in May. Another petition seeking a deferral of two years reached that threshold in the middle of September.

Kim Min-seok, identified as the ruling Democratic Party leader, said on October 22 that he was reviewing public input and wanted a final examination of the tax plan.

"Recently, there have been growing calls and diverse opinions on this issue, so yesterday I raised the need to conduct a thorough final review," Kim said.

The National Tax Service planned to finalise its draft digital asset tax notice by October 30, followed by preliminary review and public notice in November. Those preparations leave users facing two practical concerns: how their transfers will be reported and how their crypto activity may be taxed. The pending legislation and tax debate leave the final issuer rules and tax timetable unsettled.
