Republic of Korea: Financial Services Commission's amendments to enforcement decree of Financial Investment Services and Capital Markets Act enter into force

On 28 October 2025, the amendments to the Enforcement Decree of the Financial Investment Services and Capital Markets Act enter into force. The decree applies to capital market activities, particularly trading and disclosure practices by securities firms and listed companies. The amendments authorise the Korea Exchange to use pseudonymised personal data to conduct individual-based market surveillance, replacing the current account-based system, and strengthen penalty surcharge criteria for unfair trading, false disclosures, and illegal short-selling. It also introduces aggravated sanctions for financial company employees involved in insider trading or other misconduct.
