The U.S. Producer Price Index (PPI) for April rose by 1.4%, surpassing economists' forecast of 0.5%, according to recent data. This unexpected increase in PPI suggests stronger inflationary pressures, complicating the Federal Reserve's potential plans for rate cuts this year. As a result, CME's "FedWatch" tool indicates that the market now assigns a probability of over 30% for an interest rate hike before December, reflecting a shift in interest rate expectations.
