The South Korean Kospi Index experienced a sharp decline this week, breaking below the 7,000-point level for the first time since early May. The sell-off, which saw the index drop more than 6.6% at one point, was fueled by a combination of domestic and global factors, including a central bank rate hike, disappointing export data, and heightened geopolitical tensions.
On Thursday, the Bank of Korea raised its benchmark interest rate by 25 basis points to 3.00%, a move widely anticipated by analysts as the central bank sought to stabilize the won and cool inflation. However, the decision, coupled with weaker-than-expected export figures and a broader risk-off sentiment in Asian markets, triggered a massive sell-off. Large-cap stocks such as Samsung Electronics and SK Hynix both fell more than 5%, erasing billions in market capitalization. Circuit breakers were activated for some heavily traded stocks to curb excessive volatility.
The rout also reflected global uncertainties, with Japan’s Nikkei and Hong Kong’s Hang Seng indices posting steep losses. Renewed US-Iran military tensions and a surge in oil prices added to nervousness among South Korean investors, given the country’s heavy reliance on Middle Eastern crude imports. Meanwhile, SK Hynix’s blockbuster US IPO raised $26.5 billion last Friday, but its stock’s 13% first-day pop failed to lift the overall market when trading resumed in Seoul. Analysts warned that post-IPO performance often fades quickly.
Retail investors, who have been a major driver of the Korean market this year, suffered significant paper losses as the KOSPI’s psychological threshold gave way. The index had been under pressure since reaching a year-to-date high of 9,387, now down more than 25% from that peak. Looking ahead, market participants will watch for any emergency policy measures from financial authorities and the continued impact of global risk factors.
