KOSPI intraday volatility this month hit a record 6.75% average through July 16, Korea Exchange reported. The surge exceeds the 2008 financial crisis peak of 6.11% and the 1997 IMF crisis level of 5.37%, driven by semiconductor concerns, geopolitical risks, and leveraged ETF rebalancing. Korea Exchange has compiled intraday volatility data since 1987.
Intraday volatility measures the ratio of the difference between a day's high and low to the average of those two values. This month's 6.75% reading means the index moved an average of 3.37% above and below its midpoint each trading day.
KOSPI Volatility Surpasses Financial Crisis Benchmarks
Three of the top 10 highest monthly intraday volatility readings in the past 20 years occurred in the current year, according to Korea Exchange data. This month's 6.75% ranks first, followed by last month at 5.02% and May at 4.02%.

VKOSPI Reaches Highest Level Since 2009
The KOSPI200 Volatility Index (VKOSPI) closed at 87.14 on July 16. The index peaked at 96.94 on June 29, marking the highest level since Korea Exchange began official publication on April 13, 2009.
VKOSPI represents expected volatility over the next 30 days based on options pricing. The index typically rises when KOSPI falls sharply, but increases during uptrends indicate investor anxiety over short-term overheating.
Analysts Attribute Volatility to ETF Rebalancing and Sentiment Shifts
Lee Jae-won, researcher at Yuanta Securities, stated: "Recently, investors show a tendency to panic-sell at the slightest excuse. Leveraged ETF-driven volatility and the absence of net buying entities caused the index to plunge to valuations below financial crisis levels."
Seo Jeong-hoon, researcher at Samsung Securities, noted: "Since mid-last month, the index has fallen more than 20%, so concentration-driven volatility has been largely digested. Considering earnings estimates remain solid, the recent decline should be viewed as a retracement process rather than a change in earnings expectations. A rebound can be expected after overheating subsides." Seo added: "Interpreting the profit-taking process as a downturn in business conditions is clearly unfounded. The fact that earnings estimates were revised upward even during periods of extreme price volatility indicates high earnings visibility and reliability, so investment should focus on fundamentals."
