KOSPI tumbles amid U.S. interest rate concerns; Samsung's buyback insufficient

The KOSPI index declined sharply on August 31, 2026, closing at 6,685.72, down 103.16 points (1.52%) from the previous trading day. This downturn was driven by concerns over rising U.S. interest rates, leading to foreign and institutional investors selling off shares. While retail investors and share buybacks by Samsung Electronics and SK Hynix provided some support, it was insufficient to counteract the broader market sell-off.
