Wholesale prices unexpectedly fell by 0.3% in June, driven largely by a sharp decline in gasoline costs, according to the latest report from the Bureau of Labor Statistics. This drop contrasted with analysts' forecasts that predicted no change in the producer price index (PPI) for the month. On a yearly basis, the PPI showed an inflation rate of 5.5%, while May’s reading was revised downward from an initial 1.1% increase to 0.6%. Excluding food and energy, core wholesale prices increased by a modest 0.2%, coming in slightly below expectations.

The significant decline in goods prices marked the largest drop since July 2022, with energy prices plunging 6.4% and food prices decreasing by 0.6%. Gasoline prices specifically tumbled 12%, making up about two-thirds of the overall decline in the goods category. Meanwhile, service prices edged up by 0.2%, supported by a 0.4% gain in trade services, underscoring some ongoing pricing pressures in that area despite the overall softening inflation.

This report followed closely on the heels of an unexpected 0.4% decline in the consumer price index (CPI) for June, which brought the annual consumer inflation rate down to 3.5%, the largest drop since April 2020. Core consumer inflation held steady for the month but fell to an annual rate of 2.6%. These softer inflation readings, influenced by falling energy costs amid a brief easing of U.S.-Iran tensions, offer some encouragement in the Federal Reserve’s ongoing efforts to tame inflation, though it remains above the Fed’s 2% target.

Economists and market participants responded to the data by scaling back expectations for additional Federal Reserve interest rate hikes, with the September rate decision now seen as a 50-50 proposition. Fed Chairman Kevin Warsh cautioned lawmakers that the price declines do not mean inflation has been defeated. Investors are awaiting the upcoming personal consumption expenditures (PCE) price index, the Fed’s preferred inflation gauge, which is expected to reflect similar easing trends following the June reports.
