South Korea's KOSPI Volatility Hits 18-Year High With 31 Circuit Breaker Triggers in H1 2026

According to Korea Ilbo, South Korea's stock market experienced unprecedented volatility in the first half of 2026, with circuit breaker triggers (sidecar mechanism) activated 31 times, surpassing 2008 financial crisis levels. Stronger stabilization measures including trading halts were triggered five times. As market uncertainty persists, financial institutions are expanding access to defensive investment strategies previously limited to high-net-worth clients.

Defensive fund products gaining traction include loss-absorption funds where brokers absorb downside losses up to specified thresholds, zero-coupon investment accounts (IMA) offering capital preservation with 4-5% annual returns backed by broker guarantees, and long-short funds that pair undervalued stock purchases with overvalued stock short-selling to minimize volatility impact. Long-short funds showed resilience during downturns, declining approximately 1.5% when the KOSPI dropped 10%, according to market analysts.
