WASHINGTON (AP) — U.S. wholesale inflation came in hot last month. Producer prices rose 6% from a year earlier, most since December 2022, as the 10-week Iran war pushed up energy prices and put pressure on companies to pass along higher costs to consumers. The Labor Department reported Wednesday that its producer price index — which tracks inflation before it hits consumers — shot up 1.4% in April, biggest monthly gain since March 2022. The numbers were much higher than economists had forecast.
