According to people familiar with the matter, Fed Chairman Powell said in an overnight speech that Powell hinted that he was pleased with the decline in inflation this summer and that the Fed is unlikely to raise interest rates again unless there is clear evidence that increased economic activity would jeopardize inflation progress.。Powell's comments were closely related to recent comments by other Fed officials, all hinting at readiness to leave interest rates unchanged at the next meeting.。This is partly because the rise in long-term yields over the past month could slow economic growth and, if yields rise, actually replace a rate hike。In describing whether monetary policy will be tightened again, Powell twice used the word "may" instead of the tougher word "will" - "evidence of economic strength could put further inflation pullback progress at risk or justify further policy tightening."。
