South Korea's Financial Services Commission announced emergency security guidelines on November 12, 2026, requiring virtual asset service providers to significantly strengthen operational safeguards. The rules mandate continuous system monitoring with dedicated personnel, immediate response protocols for suspicious activity, and expanded use of offline storage for user assets.
Core requirements under the guidelines
Exchanges must now maintain round-the-clock monitoring of their systems with staff specifically tasked with detecting suspicious activity. The guidelines also require immediate response protocols for unusual transactions and other potential security threats.
A notable provision introduces a no-action letter mechanism that allows exchanges to freeze deposits and withdrawals based on suspected security breaches, even without confirmed hacking incidents. These letters provide regulatory reassurance that firms will not face penalties for taking such precautions.
The guidelines emphasize maximizing cold wallet storage—offline systems disconnected from the internet—for user assets. South Korea's Virtual Asset User Protection Act already mandates a legal minimum of 80% cold storage.
Current industry compliance levels
Industry data from late 2026 shows that most major exchanges already exceed the regulatory floor. The industry average cold wallet ratio stands above 95%. Upbit maintains cold wallet holdings above 99%, while Bithumb maintains approximately 94-95%. Coinone holds around 85%, meeting the legal minimum but trailing larger competitors.
Broader regulatory trajectory
The emergency guidelines serve as a precursor to the forthcoming Digital Asset Act, which will impose bank-level IT safety standards on virtual asset service providers and establish liability for damages resulting from security failures. South Korea has been steadily aligning crypto exchange operational standards with those of traditional financial institutions, citing the need to strengthen the country's position as a major crypto trading hub while enhancing consumer protections.
Implications for exchanges and users
Enhanced monitoring and faster freeze capabilities should reduce the window available to attackers. High cold storage ratios mean that successful breaches of hot wallets would expose only a limited portion of total user assets. However, the ability to freeze funds based on suspicion rather than confirmed incidents creates potential for temporary lockouts during false alarms. Developments to monitor include the final text and liability provisions of the Digital Asset Act, as well as how frequently exchanges exercise new freeze powers.
