Lee Kyungmin, a researcher at Daishin Securities, stated, "The domestic stock market weakened due to the sharp rises in international oil prices and U.S. Treasury yields," adding, "With the Consumer Price Index (CPI) to be released tonight serving as a key variable for the future direction of financial markets, market caution has grown amid surging international oil and producer prices."

He further explained, "Amid heightened external uncertainties, most sectors showed weakness, and the sharp increase in U.S. Treasury yields has especially increased the burden on growth stocks."
