South Korea's Financial Services Commission and Financial Supervisory Service ordered all domestic crypto exchanges to adopt a single, standardized system for delaying withdrawals. The new rules remove exchange discretion in granting exceptions, aiming to block voice phishing scams that exploit speed. Fewer than 1% of users will qualify for instant withdrawals. Exchanges must use consistent criteria including account history and transaction patterns. Platforms must also strengthen identity checks and monitor fund flows more closely.
