Stock markets across Asia fell sharply on Wednesday, with South Korea experiencing the steepest losses. The Kospi index dropped more than 8 percent, triggering a 20 minute trading halt under an automatic safeguard designed to curb extreme volatility. Trading later resumed, but the index remained down by more than 10 percent.

The temporary suspension was activated through a circuit breaker mechanism, which is used to calm markets during sudden and severe declines. It marked the first time since August 2024 that South Korea's index circuit breaker had been triggered. If losses reach 15 percent, trading will be halted again.

South Korea's economy is particularly sensitive to instability in the Middle East. As a major importer of oil from the region and an export driven economy, the country is vulnerable to geopolitical tensions that could disrupt energy supplies and global shipments.
