ChainCatcher news, according to Jinshi reports, economist Ed Yardeni pointed out in a report that Federal Reserve Chairman Powell's remarks at the Jackson Hole annual meeting may be more cautious than last year. He stated that Powell may adopt a wait-and-see attitude, rather than being hawkish or dovish. Yardeni believes that if inflation and employment data exceed expectations before the September meeting, the Federal Reserve may be more cautious in its decision-making.
