Seoul, March 23 (NationPress) - South Korean equities experienced a significant decline on Monday morning, as investors rapidly sold off major shares following Iran's warning that it might indefinitely close the Hormuz Strait. The benchmark Korea Composite Stock Price Index (KOSPI) dropped by 293.84 points, equivalent to 5.08 percent, settling at 5,487.36 by 11:20 a.m.
This downturn persisted, leading the main bourse operator of the country to temporarily suspend program trading for five minutes, as reported by Yonhap news agency.
On the previous Friday, prominent stock indices on Wall Street ended lower after Tehran rejected U.S. President Donald Trump's ultimatum, which threatened to target Iran's power plants if the Hormuz Strait was not reopened by Monday evening.
In response, Iran stated that it could entirely close this critical waterway, which facilitates approximately 20 percent of the world's oil supply.
This ongoing exchange of threats between the two nations heightened fears of further increases in energy prices.
In Seoul, all shares were trading in negative territory.
The market leader, Samsung Electronics, saw a decline of 4.96 percent, while its competitor, SK hynix, fell by 5.46 percent.
Hyundai Motor, South Korea's top automotive manufacturer, dropped 5.03 percent, defense giant Hanwha Aerospace decreased by 5.15 percent, and portal operator Naver lost 4.74 percent.
The Korean won was trading at 1,509.5 won against the U.S. dollar, marking a decrease of 8.9 won from the previous session. This figure represents the lowest level since March 10, 2009, when it reached 1,511.1 won during the global financial crisis.
South Korea's principal bourse operator activated a sell-side sidecar for the Korea Composite Stock Price Index (KOSPI), resulting in a temporary trading halt following a sharp drop.
Program trading for the KOSPI was suspended for five minutes at 9:18 a.m., according to the Korea Exchange (KRX).
A sell-side sidecar is initiated when the KOSPI 200 Futures index declines by 5 percent or more for at least one minute.
This incident marks the sixth time this year that the bourse operator has implemented a sell-side sidecar.
Point of View
It's crucial to emphasize the economic implications of the current geopolitical climate. The significant drop in South Korea's stock market reflects investor anxiety over potential energy price increases and the broader impacts of global tensions. Monitoring these developments is essential for understanding market trends.
