South Korea’s KOSPI volatility interruption (VI) mechanism triggered 6,646 times in October, roughly 1.8 times the 3,695 and 3,749 triggers in August and September, respectively, according to Korea Exchange data. Year-to-date VI triggers reached 53,372 by the end of October, already exceeding the previous full-year record of 35,523 set in 2020 by about 1.5 times. October’s daily average KOSPI volatility rose to 3.58% from 2.07% in September, though it remained below July’s record 7.13%. The KOSPI fell 16.19% in October amid concerns over AI profitability and a credit crisis at U.S. cloud service provider CoreWeave. The surge in VI triggers underscores heightened market turbulence in South Korea, and investors will watch whether volatility persists and whether AI-related and cloud-sector credit worries continue to weigh on the index.
