Wholesale prices in the United States rose 1.1% in May, exceeding expectations, while the Producer Price Index (PPI) saw an annual increase of 6.5%, the highest rate since late 2022. This surge in wholesale inflation is largely driven by escalating energy prices and persistent pressures from the Iran oil shock, leading to increased costs for businesses. The core PPI also recorded a monthly increase of 0.4%, although this was slightly below expectations. The rapid rise in producer prices is raising concerns about ongoing inflationary pressures within the U.S. economy.
