Korean stock markets triggered sidecar mechanisms every trading day from July 20 to 24, according to Korea Exchange data released on July 26. The five consecutive trading days saw alternating buy and sell sidecars across KOSPI and KOSDAQ markets as extreme volatility gripped trading. Middle East geopolitical risks, global AI investment sustainability concerns, and repeated semiconductor stock crashes and rebounds drove the unprecedented volatility streak. As of July 24, domestic markets have recorded 66 sidecar activations, representing the highest volatility levels on record.
Korean Markets Triggered Sidecars on All Five Trading Days from July 20-24
On July 20, both KOSPI and KOSDAQ markets triggered sell sidecars as US semiconductor stock declines rippled through Korean markets. KOSPI fell below the 6500 level intraday during what traders called "Black Monday," while KOSDAQ dropped over 5%.
July 21 saw a reversal as KOSPI surged over 4% intraday, triggering a buy sidecar. Foreign and institutional investors executed large-scale net purchases.
KOSPI triggered a buy sidecar for the second consecutive day on July 22, surging over 5% at the market open. The index closed up only 0.74% in what analysts described as a "strong start, weak finish" session.
On July 23, KOSDAQ triggered a buy sidecar on strength in bio and secondary battery sectors, which drove the index sharply higher.
July 24 brought "Black Friday" to markets. Escalating US-Iran conflict, surging international oil prices, and rising US Treasury yields combined to send KOSPI and KOSDAQ down over 5% each, triggering sell sidecars in both markets. KOSPI closed at 6690.62, down 406.27 points (5.72%), while KOSDAQ closed at 748.22, down 42.06 points (5.32%). The won-dollar exchange rate closed at 1466.6 won, up 0.2 won from the previous session.
Sidecars are mechanisms that halt program trading for five minutes when futures prices move beyond set thresholds to mitigate market shocks. KOSPI sidecars activate when KOSPI 200 futures move 5% or more from the previous day, while KOSDAQ sidecars trigger when KOSDAQ 150 futures move 6% or more (3% for the spot index) and the movement persists for one minute.

As of July 24, combined sidecar activations across the securities market and KOSDAQ market reached 66 times. The securities market recorded 41 sidecar triggers (21 sell, 20 buy), while KOSDAQ recorded 25 triggers (11 sell, 14 buy).
KOSPI circuit breakers activated 7 times, representing over half of the 13 total circuit breaker activations in market history.
Yuanta Securities Analyst Identifies FOMC and Hyperscaler Earnings as Key Variables
Kim Se-bin, a researcher at Yuanta Securities, stated that sidecars were triggered on every trading day during the week. Kim analyzed that the July 24 plunge resulted primarily from the US-Iran conflict driving oil price surges and US Treasury yield increases, which stimulated foreign investor risk-aversion sentiment. Kim characterized the decline as driven more by macro shocks than AI demand slowdown.
Kim identified next week's FOMC meeting, hyperscaler earnings from Meta and Microsoft, and SK Hynix earnings as core variables that will determine future market direction. Kim stated that at current levels, investors should focus on stocks with excessive declines rather than additional selling.
