South Korea's Financial Supervisory Service (FSS), the country's financial regulator, conducted an on-site consulting inspection of Toss Securities from the 25th to the 28th after recurring system failures and repeated investor-protection controversies. The preventive review examined the causes of the failures, information technology (IT) internal controls, staffing and systems investment, internal decision-making, support structures, and management approval procedures for product advertising and new services. The FSS also made an unusual direct visit to the firm's headquarters, where its inspection department head met CEO Kim Gyu-bin and executives responsible for consumer affairs, IT systems and information security. The review is intended to diagnose risks and encourage improvements rather than determine legal violations or impose immediate sanctions. Toss Securities was selected because of its frequent outages and large user base; National Assembly National Policy Committee data showed it accounted for 18% of securities-industry complaints in the first quarter of this year. The company acknowledged the issues and said it would comprehensively review and improve its internal-control and consumer-protection systems.
