Producer prices in the United States rose only slightly in March, and the impact of rising service prices was partially offset by falling commodity prices, easing people's concerns about the rebound in inflation. High inflation and the continued strength of the labor market prompted financial markets and most economists to postpone the expectation of the timing of the Fed's first interest rate cut from June to September. The minutes of the Federal Reserve's March 19-20 policy meeting released on Wednesday also show that policymakers are worried that inflation progress may have stalled. According to the Bureau of Labor Statistics of the US Department of Labor, the producer price index (PPI) of final demand rose by 0.2% month on month in March, and economists surveyed predicted that it would rise by 0.3%. The reading in February was confirmed as an increase of 0.6%. In March, PPI rose by 2.1% year-on-year, and in February it rose by 1.6%. The PPI report shows that the service price rose by 0.3% in March, the same as that in February. This is mainly due to the sharp rise of 3.1% in the prices of securities brokerage, trading, investment advice and related services. Portfolio management fees rose by 0.5%. Portfolio management fees, health care, hotel and motel accommodation fees and air ticket prices are all used to calculate PCE price index. After jumping by 1.2% in February, commodity prices fell by 0.1% in March. The wholesale price of gasoline decreased by 3.6%. Excluding food and energy, commodity prices rose slightly by 0.1% in March after rising by 0.3% in February.
