Kospi Sell-Side Sidecar Triggered for Second Consecutive Session Amid Deepening Selloff

Korea Exchange activated sell-side circuit breaker for second day as Kospi futures dropped over 3%, halting program trading to curb panic selling amid intense volatility.

Woofun AI reports that the Korea Exchange activated a sell-side sidecar for the Kospi index for a second consecutive trading session on Wednesday. The mechanism, which pauses sell orders in the program trading system for five minutes, was triggered at 10:25 a.m. local time after Kospi futures fell more than 3% from the previous day’s close. This intervention follows a similar activation on Tuesday, marking a rare occurrence last seen during the March 2020 market shock. At the time of the trigger, the Kospi was trading down more than 2%, extending losses from the prior session and signaling heightened anxiety among traders and institutional investors.
