KRX Derivatives Market Data Feed Breakdown Causes Trading Delays

Korea Exchange (KRX)

A malfunction in the market data distribution system delayed price updates for the KOSPI 200 futures.

The Korea Exchange experienced a technical breakdown in its market information distribution system (Koscom). For over 30 minutes, real-time price feeds for the derivatives market were frozen, leading to massive confusion among institutional traders and automated systems. KRX later identified a faulty network switch in their primary data center as the root cause.
