South Korea KOSPI Volatility Index Hits Record ~95 After 10% Stock Crash
South Korea's KOSPI 200 Volatility Index climbed to a record of approximately 95, marking the highest level of measured turbulence in the country's history. The surge implies daily swings of around 6% for the benchmark index, according to Bloomberg, and pushes the Korean fear gauge to nearly five times the U.S. VIX—the widest historical gap between the two volatility benchmarks.
The record volatility reading follows a steep ~10% plunge in South Korea's KOSPI index on June 23, which erased roughly $474 billion in market value. The rout concentrated on semiconductor stocks, with Samsung Electronics and SK Hynix falling more than 12% after a local report suggested SK Hynix might slow expansion of its AI memory chip production. The selloff was compounded by proposals from lawmakers to tax unrealized stock gains and extreme leverage among retail investors, which triggered trading halts. Although South Korean shares rebounded roughly 4% the following day, Samsung and SK Hynix now account for about 60% of the KOSPI's total market capitalization, ensuring that sentiment shifts in artificial intelligence hardware continue to dictate broader index movements.
