Republic of Korea: Financial Services Commission adopted amendments to enforcement decree of Financial Investment Services and Capital Markets Act

On 22 October 2025, the Financial Services Commission approved amendments to the Enforcement Decree of the Financial Investment Services and Capital Markets Act and related regulations concerning measures against unfair trading. The decree applies to capital market activities, including trading and disclosure practices by securities firms and listed companies. The amendments authorise the Korea Exchange to use pseudonymised personal data for individual-based market surveillance, replacing the existing account-based system, and revise the criteria for imposing penalty surcharges related to unfair trading, false disclosures, and illegal short-selling. They also establish aggravated sanctions for financial company employees involved in insider trading or other misconduct.
