South Korea's Financial Services Commission (FSC) has imposed stringent new requirements on domestic cryptocurrency exchanges, mandating real-time balance reconciliation every five minutes. This regulatory crackdown follows Bithumb's high-profile Bitcoin payout error during a February promotion, which exposed systemic vulnerabilities in exchange controls.

The FSC's directive, developed in collaboration with the Digital Asset Exchange Alliance (DAXA), aims to prevent similar incidents by enforcing near-instantaneous wallet balance verification. Exchanges must now implement automatic trading halts for significant discrepancies and enhance transparency through monthly external audits—a sharp increase from the previous quarterly review cycle.

Notably, several major platforms were found to be conducting balance checks only once every 24 hours, a practice regulators deemed dangerously outdated. The five-minute standard was specifically calibrated to match average transaction processing times while minimizing system overload.
