South Korea's benchmark KOSPI index experienced a significant downturn today, plunging more than 7% and triggering a temporary trading halt. The sharp decline was primarily driven by a technology-led sell-off on Wall Street, exacerbated by persistent concerns over US inflation and the potential for elevated interest rates.
Trading Halted Amid Steep Decline
The KOSPI extended its losing streak to seven consecutive sessions, marking its longest period of declines since September 2024. At its lowest point, the index was down 7.49%, or 450.02 points, reaching 5,558.79 earlier in the session.
In response to the rapid fall, the South Korean stock exchange activated its sell-side "sidecar" mechanism. This measure is designed to curb excessive volatility during sudden market swings by suspending program sell orders for a period of five minutes.
Tech Giants Lead the Sell-Off
Technology stocks bore the brunt of the market's woes. Samsung Electronics saw its shares tumble by 9.05%, while SK Hynix, another major chipmaker, plunged by an even steeper 11.06%. Heavy selling in these key chipmakers dragged the broader market lower as investors reacted to the weakness observed on Wall Street and re-evaluated their exposure to the technology sector amidst a challenging global interest-rate outlook.
Regional Markets Also Impacted
The ripple effect of the tech sell-off and inflation fears was felt across Asia:
- Japan's Nikkei index was trading 4.53% lower.
- Hong Kong's Hang Seng index saw a 1% decline.
- China's mainland index, the Shanghai Composite, dropped 1.45%.
- Taiwan's TAIEX also experienced a significant fall of 2.79%.
Overnight, the tech-heavy Nasdaq Composite in the US had settled 1.88% lower, setting a negative tone for Asian markets.
Inflationary Pressures Fuel Concerns
Underlying the market anxiety were fresh US inflation figures. The US headline inflation accelerated to 3.7%, surpassing the estimated 3.6%, while core inflation rose to 2.6%. Hariselvan Radhakrishnan, Founder & CEO of HST Wealth, noted that these figures suggest energy costs are beginning to reinforce underlying price pressures.
"The data suggested that energy costs are beginning to reinforce underlying price pressures, increasing the possibility of another Federal Reserve rate increase or an extended period of restrictive policy," said Hariselvan Radhakrishnan.
Although the US 10-year treasury yield edged slightly lower to 5.19%, this modest decline offered little reassurance to investors, as yields remain near multi-decade highs, indicating persistent concerns about future interest rates.
