Still, Powell’s remarks suggest the Fed will proceed carefully in the coming months and will make its rate decisions based on how inflation and unemployment evolve. The Fed has three more meetings this year, including next month, in late October, and in December, and it’s not clear whether the Fed will cut at all those meetings.

Powell delivered the guidance in a highly anticipated speech on Friday at the central bank's annual symposium in Jackson Hole, WY.

Major brokerages, including Barclays, BNP Paribas and Deutsche Bank, now expect a 25-basis-point U.S. Federal Reserve rate cut in September following Chair Jerome Powell's shift in tone at Jackson Hole toward rising risks in the labor market.
