(Reuters) -Barclays and BNP Paribas expect the U.S. Federal Reserve to cut interest rates in September, after Chair Jerome Powell signaled a shift toward an easing bias in a speech at Jackson Hole, the brokerages said in separate notes on Friday.

Barclays and BNP Paribas expect the U.S. Federal Reserve to make a 25-basis-point interest rate cut in September, according to notes dated Friday, citing Chair Jerome Powell's shift in tone at Jackson Hole toward rising risks in the labor market.

Now that Federal Reserve Chair Jerome Powell has signaled that the central bank could soon cut its key interest rate, he faces a new challenge: how to do it without seeming to cave to the White House's demands.
