what happened
The Korea Exchange activated its SIDECAR mechanism after KOSPI 200 index futures climbed 5%. Program buying in the KOSPI index was suspended for five minutes.
Binance reported, citing Odaily, that the measure applies specifically to program buying.
why it matters
SIDECAR is a safeguard that temporarily curbs sharp moves when index futures run far from the underlying index. For investors, it signals elevated volatility in the South Korean equity segment and a short pause for automated strategies.
