South Korea Weighs Crypto Account Freezes to Block Suspected Market Manipulation

Highlights:

• South Korea is considering early payment freezes to stop suspected crypto price manipulation.
• Regulators want to apply stock-market-style crypto account freezes to improve crypto market enforcement.
• The second-phase crypto laws may expand powers to block transfers beyond exchanges and private wallets.

South Korea’s Financial Services Commission is reviewing a system to suspend payments tied to suspected crypto price manipulation. The plan would block withdrawals, transfers, and payments before suspects move funds. Regulators believe early action can stop profits from disappearing during probes. Currently, authorities often wait for court warrants before freezing assets. As a result, suspects gain time to hide funds.

The FSC says manipulation tactics can generate large unrealized gains within minutes. These tactics include front-running, automated wash trading, and aggressive high-price buying. Regulators note that such gains can vanish once suspects sell positions. Therefore, delayed action weakens enforcement outcomes. Early payment freezes could reduce that risk.

Officials discussed the idea during a closed-door meeting held in November. The meeting occurred while regulators reviewed a crypto price manipulation case. Participants said current laws limit early asset control. Investigators must often wait until prosecutors seek court approval. Consequently, enforcement starts after market harm occurs.

The ease with which crypto assets are transferred also raised red flags among regulators. When money comes out of exchanges, it becomes more difficult to track. In addition, moving it to private wallets provides additional challenges to investigators. Thus, regulators claim the crypto markets require quicker reaction instruments.

Stock-Market Rules Shape Crypto Account Freezes

The FSC is looking to existing stock-market tools for guidance. Amendments to the Capital Markets Act took effect in April 2025. These rules allow authorities to freeze accounts suspected of unfair trading. Regulators can act before profits leave the market. Officials now want similar powers for crypto cases.

During the November meeting, officials cited a major stock manipulation case. Investigators froze payments on 75 accounts tied to unfair trading. Suspects had mobilized about 100 billion won in capital. They generated roughly 40 billion won in market gains. Early freezes blocked withdrawals of both realized and unrealized profits.

Authorities said the case proved the value of early intervention. The freezes stopped suspects from selling remaining holdings. Regulators later prepared fines reaching double the illicit gains. Prosecutors and courts then pursued asset recovery. Officials described the action as a strong enforcement signal.

The same logic, according to the participants of the meeting, applies to crypto markets. They claimed that crypto account freezes could freeze unrealized gains prior to the sale of tokens by the suspects. Some of the members advocated that the stock-market regulations should be applied to virtual assets. They emphasized that crypto assets are faster-moving than stocks.

Second-Phase Crypto Law May Expand Enforcement Tools

The payment freeze review links to South Korea’s second phase of crypto legislation. The first phase focused on user protection and basic oversight. Legislators are now considering more comprehensive regulations regarding market abuse and stablecoins. Nevertheless, authorities have not presented formal proposals.

Regulators indicate that existing laws restrict action when assets move beyond exchanges. Governments can pause deposits and withdrawals on platforms. However, they cannot prevent transfers to banks or personal wallets. This gap raises enforcement risks. Officials believe stronger tools could close that gap.

Other agencies share similar concerns. In October, the National Tax Service warned that cold wallets do not ensure protection. The agency cited its power to search homes and seize offline storage devices. In December, the FSC also reviewed bank-level liability for exchanges. That review focused on user losses after hacks or system failures.
