The dollar strengthened after Federal Reserve Chairman Powell struck a cautious tone about the prospect of future rate cuts. He cited risks to both employment and inflation and avoided a clear signal on whether a rate cut would occur at the October meeting. Powell said that if rate cuts were too large, the work of combating high inflation would be incomplete, and the Fed might need to raise rates later. However, if the Fed keeps interest rates too high for too long, the job market could weaken. The US dollar index (DXY) rose 0.24% to 97.45 today. (Golden Ten)
