U.S. consumer prices increases slowed in July even as they remained at a 13-year high on a yearly basis and there were tentative signs inflation has peaked as supply-chain disruptions caused by the pandemic work their way through the economy. The data could provide some support to Fed officials who have repeatedly said that the current burst in inflation is temporary and likely to fade as the handful of categories that have caused inflation to surge in recent months get back on an even keel.

The consumer price index increased 0.5% last month after climbing 0.9% in June, the Labor Department said on Wednesday. In the 12 months through July, the CPI advanced 5.4%. The drop in the month-to-month inflation rate was the largest in 15 months.

Price gains for used cars and trucks, which have accounted for an outsized chunk of the inflation boost in recent months, rose 0.2%, a sharp drop from the 10.5% increase the prior month. Prices for airline fares also edged down 0.1%.
