South Korea will let crypto exchanges freeze withdrawals on suspected hacks

What happened. FSC Vice Chairman Shin Jin-chang chaired the meeting. Supervisors and exchanges attended, including Dunamu (Upbit), Bithumb, Coinone and Streami (GOPAX). Three topics: emergency response rules for attacks, freezing withdrawals on suspected hacks, and exchanges joining the Financial Security Institute.

Why the rule changes. The Virtual Asset User Protection Act bars exchanges from blocking deposits and withdrawals without legitimate grounds and explicitly allows it only when a hack is clear. Exchanges said it was unclear whether they could act on suspicion alone. The FSC cited the Binance hack as a case where speed decides losses. A no-action letter means the regulator will not penalize such a halt if the conditions are met.

What else is required. 24/7 monitoring. Exchanges that cannot monitor around the clock must process deposits and withdrawals only during staffed hours and tell users in advance. The legal cold storage minimum is 80%, and all exchanges already hold more than 95%. The FSC asks them to keep hot wallet balances to a minimum, split them across several wallets, and raise insurance and reserves for payouts.

Next. Only 5 of 28 crypto firms, the won-market exchanges, are members of the Financial Security Institute. The FSC wants the rest to join and will update the exchange security check standard by year end. The planned Digital Asset Act would give exchanges IT safety duties and liability for damages at the level of financial companies.
