US wholesale inventories rose 0.7% month-on-month to $1,013.1 billion in September 2025, exceeding the 0.6% advance estimate and following a 0.6% increase in August. The gain marked an eighth consecutive monthly increase, while inventories rose 7.6% from a year earlier. Durable-goods inventories increased 0.6%, led by a 2.5% surge in electrical goods and a 1.3% rebound in hardware, developments likely linked to business spending on artificial-intelligence infrastructure. Nondurable-goods inventories climbed 0.9%, supported by petroleum, chemicals and apparel, although farm-product and alcohol inventories declined; petroleum stocks alone jumped 10.6%. Wholesale sales advanced 2.8% after rising 2.0% in August, reducing the time needed to clear inventories to 1.21 months from 1.23 months. Inventory investment rebounded in the third quarter after five consecutive quarterly contractions and contributed 1.61 percentage points to the economy's 3.4% annualized growth rate. The inventories-to-sales ratio was also reported at 1.34 months in September 2025.
