Americans already contending with persistent and stubbornly high inflation just got more unwelcome news on Tuesday: There are more price hikes likely coming down the pike.
Wholesale inflation picked up in April to its highest rate in a year, according to Bureau of Labor Statistics data released Tuesday.
The Producer Price Index, which measures the change in prices that manufacturers pay to suppliers, was 2.2% for the 12 months ended in April, according to Bureau of Labor Statistics data released Tuesday.
That gain is higher than what was seen in March, which was downwardly revised from 2.1% to 1.8%.
