NEW YORK (Reuters) -Federal Reserve Chair Jerome Powell's closely watched Jackson Hole speech on Friday boosted optimism in markets that the U.S. central bank is poised to ease rates, sending investors to pile into riskier assets and interest-rate-sensitive sectors.

Wall Street cheered remarks from Federal Reserve Chair Jerome Powell in Jackson Hole opening the door to a rate cut in September.

If inflation starts climbing again after a rate cut, “the Fed will have to reverse course — and in the worst case, start hiking again,” Slok said.
