Seoul Stocks Decline for Second Day Amid Rising Bond Yields

On October 7, 2026, South Korean stocks experienced a nearly 2% decline, marking the second consecutive day of losses. The drop was primarily led by declines in technology shares, as concerns over rising bond yields intensified, signaling potential worries about future economic growth.

The benchmark Korea Composite Stock Price Index (KOSPI) closed down 137.49 points, or 1.98%, at 6,803.90. This decline followed a brief recovery after opening 1.11% lower, but investor sentiment remained cautious amid elevated bond yields.

Despite gains on Wall Street the previous night, local shares fell as foreign and institutional investors turned net sellers. Analysts noted that the KOSPI faced renewed pressure from rising international oil prices and U.S. Treasury yields. Lee Kyung-min, an analyst at Daishin Securities, mentioned that investors adopted a wait-and-see approach ahead of Samsung Electronics' earnings report.

Major market players like Samsung Electronics and SK Hynix saw significant declines, with Samsung losing 1.29% and SK Hynix dropping 2.82%. The Korean won, however, strengthened against the U.S. dollar, closing at 1,340.4 won.

Overall, the market's performance reflects growing concerns about the impact of rising bond yields on economic stability and investor confidence.
