Seoul, April 7 South Korean stocks nosedived more than 5.5 percent on Monday, extending their losing streak to a fourth consecutive day, as investors panicked over an escalating global trade war triggered by US reciprocal tariffs. The Korean won fell by the most since the COVID-19 pandemic against the U.S. dollar.
The benchmark Korea Composite Stock Price Index (KOSPI) shed 137.22 points, or 5.57 percent, to close at 2,328.20. The tech-laden KOSDAQ also dipped 5.8 percent, reports Yonhap news agency.
Shortly after the stock market opened, the bourse operator issued the first sidecar order since August 2024, halting program purchasing for five minutes, after the KOSPI 200 index shed over 5 percent for more than 1 minute, reports
Trade volume was a bit heavy at 615.2 million shares worth 10.5 trillion won ($7.16 billion), with losers far outnumbering winners 862 to 68.
Foreigners dumped 2.09 trillion won worth of local shares, while retail investors and institutions purchased 1.67 trillion won and 253.2 billion won, respectively.
The KOSPI nosedived as investors dumped stocks amid growing fears of a recession following the Trump administration's announcement of reciprocal tariffs last week, prompting China to fire back with 34 percent tariffs on U.S. goods and export controls on rare earths, while threatening additional steps in the near future.
"Volatility in the Korean stock markets heightened on the Trump administration's stronger-than-expected tariff policies," Park Seok-joong, an analyst at Shinhan Securities, said.
"None of the Korean export industries will be able to evade the influence of the U.S. tariff scheme."
