U.S. business inventories rose 0.2% month-over-month in September 2025, following a flat reading of 0.0% in August, according to the latest data updated on 16 December 2025. The move marks a modest buildup in stock levels after businesses had effectively held inventories steady the month before.
The data, measured on a month-over-month basis, indicate that companies slightly increased their goods on hand in September compared with August. By contrast, the previous figure for August showed no change from July. The shift from zero growth to a 0.2% rise suggests firms may be cautiously replenishing inventories, potentially in response to demand expectations heading into the final quarter of the year.
While the increase is small, changes in business inventories are watched closely as they feed directly into broader measures of economic activity. A sustained pickup in stock rebuilding could support stronger output figures, while also offering clues about how companies are positioning themselves amid evolving demand and supply conditions in the U.S. economy.
