Wholesale inflation cools down in June, headlined by a 0.3% PPI drop

Wholesale prices unexpectedly fell in June, with the producer price index (PPI) dropping 0.3% against economist forecasts for a flat reading, the largest monthly decline since April 2025. Goods prices led the pullback, down 1.4%, the steepest such drop since July 2022, while services prices rose a modest 0.2%.

The decline was driven largely by falling energy costs, with gasoline prices tumbling around 12% and accounting for roughly two-thirds of the monthly drop, as easing US-Iran tensions helped stabilize oil markets following the Strait of Hormuz crisis that had disrupted global energy supply for much of the spring. Iran had effectively closed the strait, a critical corridor for oil and LNG shipping, after a US-Israeli air campaign in late February, and by June, signs of a fragile reopening tied to easing tensions helped bring energy costs back down.

On an annual basis, the pullback helped headline PPI cool to 5.5% from 6.0% in May, easing for the first time in five months and coming in well below forecasts. Core PPI, which excludes food and energy, still rose modestly for the month and remained elevated year over year, though also below expectations, suggesting underlying pipeline inflation pressure is moderating alongside the drop in energy costs.

The report offers some relief on the inflation front, though how durable June's improvement proves will likely depend on whether Strait of Hormuz shipping normalizes on a sustained basis or whether renewed US-Iran friction reignites energy-price volatility. Investors are likely to watch subsequent PPI and CPI prints, along with developments out of the Gulf, for confirmation that the cooling trend is more than a one-month reprieve tied to a fragile geopolitical truce.
