South Korea tightens oversight of outbound crypto transfers

South Korea’s Financial Services Commission, Financial Supervisory Service and the country’s anti-money-laundering unit issued guidance in recent weeks requiring tighter controls on companies that move cryptocurrency overseas. The rules target virtual asset service providers and related firms to improve tracing of funds and reduce use of foreign platforms to hide taxable gains or launder proceeds of crime.

The guidance requires firms that handle digital assets to notify regulators about significant cross-border transfers, keep more detailed transaction records and apply enhanced customer due diligence for outbound movements. The measures apply to domestic crypto exchanges, token issuers and financial firms that custody or route digital assets for clients.

Under the guidance, firms must flag and report transfers that meet internal or regulatory risk criteria, retain information on counterparties and the jurisdictions involved, and operate transaction-monitoring systems that specifically cover outbound transfers. Regulators wrote that noncompliance may lead to fines, restrictions on business activities or revocation of operating permissions.

Banks and payment service providers that process payments for crypto firms are asked to increase scrutiny of transfers tied to virtual asset transactions. The agencies expect closer cooperation between banks and crypto firms so transfers linked to token purchases, withdrawals or on-chain movements can be traced back to customer accounts when needed. Authorities said requests for additional documentation and temporary holds on transfers may be used when suspicious patterns are detected.

The new oversight is aligned with international anti-money-laundering standards, including efforts to apply the travel rule to virtual asset transfers and to share information with foreign counterparts. Regulators plan to step up information exchanges with overseas supervisors and consider joint investigations for cross-border fraud or regulatory breaches.

Industry groups were notified of the changes and given short deadlines to update compliance systems. Regulators intend to run targeted inspections of high-risk firms and expect many exchanges to upgrade technology to automate reporting and monitoring of outbound flows. Smaller providers may face pressure to partner with licensed custodians or to limit services that enable transfers to jurisdictions with weak oversight.

Officials cited a rise in activity routed through foreign platforms and an increase in cases where assets moved overseas were later linked to tax disputes or criminal probes. The guidance builds on existing laws that require registration of exchanges, anti-money-laundering obligations for virtual asset service providers and routine reporting of suspicious transactions by financial institutions.
