Kiwoom Securities Faces MTS Outages and Settlement Delays Despite New Risk Management System

According to Bloter, South Korea's Kiwoom Securities has experienced consecutive operational incidents recently despite implementing an ICT risk management framework in 2025. The company reported mobile trading system (MTS) access failures last month and, more significantly, processing delays in margin deposits that resulted in forced liquidations in some customer accounts. Kiwoom Securities stated it is providing compensation to affected customers.

The incidents highlight growing operational pressures as Kiwoom expands its customer base and services. Customer accounts increased by 1.3 million to 16.2 million in 2025, while staff headcount rose to 1,197 from 994 in 2024. The company began issuing short-term financial instruments in November 2025, expanding its reliance on digital platform stability.
