South Korea Considers Preemptive Crypto Account Freezes to Combat Market Manipulation

South Korean financial authorities are evaluating a new regulatory measure that would enable preemptive freezing of crypto accounts suspected of market manipulation. The move aims to address ongoing concerns about illicit activities in the rapidly evolving cryptocurrency sector, aligning crypto enforcement more closely with traditional securities regulation.

Key Takeaways

• The proposed system would mirror existing tools used in South Korea’s stock market to freeze manipulated accounts.


• The initiative responds to the challenge of delayed asset forfeiture due to court warrant procedures in crypto cases.


• Broader regulatory efforts include measures to hold exchanges liable for hacks and enforce stricter oversight.

Expanding Enforcement Tools to Crypto Markets

South Korea’s Financial Services Commission (FSC) is considering the introduction of a payment suspension system that would allow regulators to freeze cryptocurrency accounts suspected of manipulating markets. Currently, authorities face delays due to court warrants, which can give suspects time to conceal illicit funds. The new system would enable earlier intervention, similar to existing measures in the stock market, where authorities can prevent the cashing out of profits suspected of being generated through manipulation tactics such as front-running, wash trading, or placing large buy orders.

The FSC has highlighted that manipulation tactics in crypto markets can quickly generate large, unrealized gains that vanish once authorities intervene. Therefore, enabling preemptive account freezes aims to prevent these illicit profits from being realized or withdrawn, effectively curbing market abuse at an earlier stage.

In April 2025, amendments to South Korea's Capital Markets Act took effect, empowering authorities to freeze accounts linked to unfair trading or illegal short sales. During a closed-door meeting in November, regulators discussed extending similar measures to crypto markets, including reviewing the first case of price manipulation under these amended rules. Given the ease of transferring assets into private wallets, regulators argue that crypto markets require even stronger tools to combat illicit activities.

Additionally, the regulatory landscape is shifting as authorities increase oversight beyond market manipulation to address other risks. The National Tax Service has asserted its authority to seize cold wallets during tax evasion investigations, signaling a tougher stance on offline storage. Furthermore, the Financial Services Commission has explored imposing bank-level liability on crypto exchanges, requiring platforms to compensate users for hack-related losses, even in the absence of proven negligence.

This series of measures indicates a move towards comprehensive regulation designed to safeguard market integrity and protect investors, aligning South Korea’s crypto oversight with traditional financial regulatory practices.
