South Korean Stocks Decline Amid AI Spending Concerns and Fed Uncertainty

The benchmark Korea Composite Stock Price Index closed at 5,593.56 on Thursday, representing a loss of 69.68 points or 1.23 percent. The market experienced significant volatility during the session, reaching an intraday high of 5,976.82 before plunging to a low of 5,547.41. This decline follows two days of deep routs driven by uncertainty regarding the Federal Reserve's interest rate outlook and skepticism over whether heavy investments in artificial intelligence will yield sufficient returns to justify current valuations. The U.S. Federal Reserve recently maintained its benchmark interest rate at 3.5 to 3.75 percent without providing clear guidance on future policy easing.

Tech stocks led the downward trend. Market bellwether Samsung Electronics fell 0.72 percent to 207,000 won, while SK Hynix plunged 5.64 percent to 1.32 million won. Retail investors sold a net 1.43 trillion won in stocks, whereas institutions and foreigners were reported by some sources as net purchasers of 66.3 billion won and 1.34 trillion won respectively. Other notable declines included Naver, which slid 4.05 percent to 201,500 won, and Hyundai Motor, which declined 0.71 percent to 351,000 won.

In response to the volatility, South Korea's Financial Services Commission announced plans to implement measures to cool the single-stock leveraged exchange-traded fund market as early as possible. These measures include revising the Capital Markets Act and requiring brokerages to set limits on the maximum amount of investment into these ETFs to prevent excessive risk. Some authorities have already increased the minimum cash deposit for such investments.

Retail investors have suffered significant losses, with some reporting deep debts after investing in risky products during a previous surge where the KOSPI peaked at 9,115 points in June. Outlets of a center lean frame these events differently: some describe the situation as a bursting AI bubble or a massive rout that government curbs may not be able to fix, while others focus on regulatory responses and macroeconomic data. The outlet with a center-right lean frames the event primarily through technical market movements and Federal Reserve policy.
