FIU Inspections and Sanctions for Virtual Asset Service Providers
Types of sanctions, responding at the inspection stage, and prior notice and post-disposition remedies
Virtual asset service providers are subject to anti-money laundering obligations under the Act on Reporting and Using Specified Financial Transaction Information, including customer due diligence, suspicious transaction reporting, and the prohibition on dealing with unreported service providers. The Korea Financial Intelligence Unit (FIU) inspects compliance and imposes sanctions such as business suspension and administrative fines when violations are found.
The level of sanctions is largely determined during the inspection stage and in the opinion submitted after prior notice. Organizing the scope and circumstances of violations before a disposition is issued is more important than challenging it afterward.
1. Types of Sanctions under the Act
The Act provides for suspension of all or part of a provider's business for up to six months where a corrective order is not followed or a violation is serious, and for ex officio cancellation of a report where the reporting requirements are no longer met.
Violations of customer due diligence obligations and refusals of inspection may be subject to administrative fines of up to KRW 100 million, and the total may increase where fines are calculated per violation. Measures against officers and employees may be required in addition to institutional sanctions.
2. Classifying Transactions at the Inspection Stage
Inspections focus on customer due diligence procedures, suspicious transaction reporting, and deposits and withdrawals involving unreported overseas providers. Transactions identified as violations should be classified by type and reviewed individually to confirm whether each is in fact a violation.
Documents and answers submitted during an inspection form the basis of the sanctions review, so answers should remain consistent and copies of submitted materials should be retained.
3. Implementing and Documenting Corrective Measures
Improvements to customer due diligence procedures, changes to monitoring criteria, amendments to internal control rules, and staff training should be implemented before the disposition, with the dates and details recorded.
Corrective measures already implemented may be considered in assessing the seriousness of the violation and the risk of recurrence, and are more persuasive than a plan alone.
4. Prior Notice and Submission of Opinions
Under the Administrative Procedures Act, the provider receives prior notice of the proposed disposition and an opportunity to submit opinions. At this stage, the scope of the violations, the method of counting them, the presence of intent or gross negligence, and mitigating factors can be addressed specifically.
Because the business impact depends heavily on the scope and duration of any suspension, the opinion should also explain the effect of a suspension on user protection and the market. Deadlines for submitting opinions are often short, so the scope of the response should be determined immediately.
5. Stay of Execution and Appeals after the Disposition
A disposition may be challenged through an administrative appeal or an administrative lawsuit. Because a business suspension is enforced even while litigation is pending, an application for a stay of execution should be considered at the same time.
A stay of execution is assessed on the basis of irreparable harm, urgency, and the effect on public welfare. Notification obligations to partner banks providing real-name accounts and to overseas counterparties should also be prepared in accordance with the relevant contracts.
| Item | Key Review Points |
|---|---|
| Types of sanctions | Full or partial business suspension, ex officio cancellation of report, per-violation administrative fines, measures against officers and employees |
| Inspection stage | Classification of transactions by violation type, consistency of answers, retention of submitted documents |
| Before disposition | Records of implemented corrective measures, opinion and mitigating factors after prior notice |
| After disposition | Administrative appeal and lawsuit, stay of execution, notification to counterparties |
6. Implications for Companies
FIU sanctions directly affect business continuity, real-name account arrangements, and overseas business relationships. Providers should systematically classify transactions and record corrective measures from the start of an inspection and prepare for the opinion stage after prior notice.
Providers expecting a regular inspection should review their customer due diligence and suspicious transaction reporting records in advance and address transaction types that are likely to be flagged.
