South Korea's KOSPI opened lower on Wednesday, dropping about 1.2% to 8,622 points [1].

The decline follows a four-day winning streak and reflects growing investor anxiety regarding global monetary policy. Because the South Korean market is highly sensitive to capital flows, the shift in foreign investor behavior often signals a broader change in regional risk appetite.

Market participants are closely monitoring the upcoming U.S. Federal Open Market Committee (FOMC) monetary policy decision [1]. This anticipation has led foreign investors to switch from net buying to net selling [1].

Major technology stocks showed diverging trends during the opening. Samsung Electronics shares fell over two% to approximately 334,000 won [1]. In contrast, SK Hynix saw a slight increase of 0.8%, reaching approximately 2,400,000 won [1].

The KOSDAQ index initially rose 0.12% to 1,019 points [1]. However, the index turned downward shortly after the open.

"The KOSPI, which had closed higher for four consecutive trading days, started today with a slight downward trend," a YTN News anchor said [1].

Reporter Kim Se-ho said that while the index started lower, it has since shown strong resistance in the late 8,600 range [1]. Kim also said that the KOSPI opened at 8,622, down 1.2% from the previous day [1].

South Korea's KOSPI opened lower, dropping about 1.2% to 8,622 points.

The volatility in the KOSPI highlights the interdependence of East Asian equity markets and U.S. monetary policy. When the FOMC signals potential interest rate shifts, foreign capital often exits emerging markets to seek safer or higher-yielding assets in the U.S., putting downward pressure on heavyweights like Samsung Electronics.
