KoFIU — Financial intelligence, VASP registration

Act on Reporting and Using Specified Financial Transaction Information — VASP reporting to KoFIU and AML/CFT duties added by Law 17113 of 24 March 2020 (in force 25 March 2021); Law 21358 of 19 February 2026, in force six months after promulgation, adds major shareholders to the report and new refusal grounds on financial soundness, social credit and internal controls (Art. 7(1)(1-2), 7(3)(5)-(6)).

Virtual Asset User Protection Act (Law 19563 of 18 July 2023, in force 19 July 2024) — user deposit and asset protection (Arts. 6-7), mandatory insurance, mutual aid or reserves against hacking and outages (Art. 8; FSC rule proposal minimum KRW 3 billion for KRW-market exchanges and KRW 500 million for other providers, a cover requirement rather than equity capital), and prohibition of insider trading, market manipulation and other unfair trading (Art. 10).

A virtual asset service provider must report to the Korea Financial Intelligence Unit (Act on Reporting and Using Specified Financial Transaction Information, Art. 7), which may refuse the report without ISMS certification or a real-name verified bank deposit and withdrawal account unless KoFIU exempts the provider (Art. 7(3)(1)-(2)); since Law 21358 of 19 February 2026 the report also covers major shareholders; an accepted report is valid for 3 years and must be renewed (Enforcement Decree Art. 10-15); KoFIU listed 28 providers with accepted reports as of 30 September 2026.

Under the Virtual Asset User Protection Act a provider holding users' virtual assets must keep them segregated from its own and actually hold the same type and quantity (Art. 7(2)), and must store offline a share set by decree (Art. 7(3)): the Enforcement Decree sets at least 70%, at the ratio the FSC fixes by notice (Decree Art. 11(1)), and the FSC's 11 December 2023 rule proposal set that ratio at 80%; user KRW deposits must be placed with a bank or similar custodian at 100% or more of the total (Decree Art. 8(3)), and insurance or reserves against hacking and outages are mandatory (Act Art. 8).

A virtual asset exchange must report to the Korea Financial Intelligence Unit under Article 7 of the Act on Reporting and Using Specified Financial Transaction Information, and KoFIU may refuse the report if the exchange lacks ISMS certification or does not deal through a real-name verified deposit and withdrawal account linking the exchange's and its customers' accounts at the same bank (Art. 7(3)(1)-(2)); under the Virtual Asset User Protection Act an exchange must monitor abnormal trading continuously and notify the FSC and FSS of suspected unfair trading (Art. 12).

Under Article 7(1) of the Act on Reporting and Using Specified Financial Transaction Information, a virtual asset service provider must file a report (신고) with the Korea Financial Intelligence Unit before operating, and is subject to the Act's customer due diligence and suspicious-transaction reporting duties from 25 March 2021 (Law 17113 of 24 March 2020); operating without a report carries up to 5 years' imprisonment or a fine of up to KRW 50 million (Art. 17(1)).

The Virtual Asset User Protection Act (Law 19563, enacted 18 July 2023, in force 19 July 2024) prohibits the use of material non-public information, market manipulation and fraudulent unfair trading in virtual assets (Art. 10); violators face at least 1 year's imprisonment or a fine of 3 to 5 times the gain (Art. 19(1)), rising to life or at least 5 years' imprisonment where the gain or loss avoided is KRW 5 billion or more (Art. 19(3)), and the FSC may impose a penalty surcharge of up to twice the gain, or up to KRW 4 billion where no gain can be calculated (Art. 17(1)).

The Korea Financial Intelligence Unit receives and accepts virtual asset service provider reports under Article 7 of the Act on Reporting and Using Specified Financial Transaction Information (28 providers accepted as of 30 September 2026), receives suspicious transaction reports, which must be filed without delay (Art. 4(1)), and supervises, inspects and sanctions reporting entities for AML compliance (Art. 15).

Under the Virtual Asset User Protection Act, in force 19 July 2024, the Financial Services Commission supervises and inspects virtual asset service providers (Art. 13), investigates unfair trading with the Financial Supervisory Service (Art. 14), may order corrective action, issue warnings or suspend all or part of a provider's business (Art. 15), and may impose penalty surcharges for unfair trading (Art. 17).
