The Korea Composite Stock Price Index (KOSPI) opened down 0.52% on Tuesday, then extended its losses, falling 84.81 points, or 1.24%, to 6,735.21 as of 9:15 AM. This followed an overnight decline in US stocks, triggered by renewed military conflict between the US and Iran, and hawkish remarks from Federal Reserve Chairman Warsh, which intensified market concerns about inflation.
