The Taiwan stock market closed down 312.77 points, finishing at 18,793.43. U.S. President Trump criticized Federal Reserve Chairman Powell for the slow pace of interest rate cuts and even threatened to replace him. This led to all four major U.S. stock indices falling, dragging the Taiwan market down as well. Today (22nd), the market opened with a drop of 115.34 points, with major stocks declining significantly, reaching a low of 18,793.43 during the day. Ultimately, the Taiwan stock index ended down 312.77 points, a decline of 1.64%, with a trading volume of NT$243.16 billion.
