South Korea’s KOSPI Drops 6.6%, Triggers Circuit Breaker Amid Asian Selloff

businessstocksworldsouth-korea 45 posts · 21 accounts

South Korea’s KOSPI fell about 6.6% in Seoul trading on June 10, triggering a circuit breaker that temporarily suspended algorithmic trading, while Samsung Electronics dropped 6.8% and chip shares resumed losses. The decline came amid a broader regional selloff, with losses also reported in Japan, China, Hong Kong and Taiwan.

The move reversed much of the benchmark’s 7.27% rebound in the previous session and followed an earlier more than 8% plunge that prompted a 20-minute halt, underscoring continued volatility in Seoul equities. Investors were also digesting Japan’s producer-price index, which rose 6.3% from a year earlier, above the 5.5% expected and the highest level in more than three years.

Shockingly, headlines 30 minutes apart can be “Korea down 10%” and “Korea flat on the day”. That’s the power of Korea.
