US wholesale prices rose last month at the fastest pace since April, suggesting that inflationary pressures remain despite a year-and-a-half of higher interest rates.

The Labour Department reported on Wednesday that its producer price index — which measures inflation before it hits consumers — climbed 2.2% from a year earlier. That was up from a 2% uptick in August.
