US Wholesale Sales Hit $840.1 Billion in September, Up 19.8% Year-Over-Year

US merchant wholesalers posted $840.1 billion in sales in September 2026, up 19.8 percent (±0.7 percent) from September 2025, the U.S. Census Bureau reported. The month-over-month gain came in at 2.8 percent (±0.4 percent) against the revised August level.

The figures cover merchant wholesalers only, excluding manufacturers' sales branches and offices. All data are adjusted for seasonal variations and trading day differences, but not for price changes — meaning the year-over-year growth reflects both volume and price effects combined.

The September reading landed well above the prior month's pace. The July-to-August percent change was itself revised upward in the Monthly Wholesale Annual Revision Report, from up 1.8 percent (±0.2 percent) to up 2.0 percent (±0.2 percent), signaling that momentum in the wholesale channel built through the third quarter.

What does this mean for inventory positions?

Total inventories at merchant wholesalers stood at $1,013.1 billion at the end of September, up 0.7 percent (±0.2 percent) from the revised August level and up 7.6 percent (±1.1 percent) from September 2025. The August-to-September change was revised from the advance estimate of up 0.6 percent (±0.2 percent) to up 0.7 percent (±0.2 percent).

The gap between the two growth rates is the story for distribution economics. Sales expanded at 19.8 percent year over year while inventories grew only 7.6 percent. Stock levels are not keeping pace with demand, and distributors are effectively running leaner than a year ago.

How lean is the channel now?

The September inventories/sales ratio — a standard measure of how many months of sales the held inventory represents, calculated on seasonally adjusted data — came in at 1.21. A year earlier, in September 2025, the ratio stood at 1.34.

That 0.13-point drop marks a substantial tightening. A lower ratio means faster inventory turns: wholesalers are converting stock into sales more quickly, which typically supports gross margin performance by reducing carrying costs, obsolescence risk and working capital tied up on the balance sheet.

For distributors, the direction of the ratio carries two implications. On one hand, leaner inventory improves return on working capital and cash flow. On the other, a ratio falling this fast while sales grow near 20 percent raises the practical question of stockout exposure — whether distributors can sustain service levels if demand holds at this pace.

The data measure merchant wholesalers as an aggregate across verticals and do not break out sectors such as industrial, electrical, plumbing, grocery or pharmaceutical distribution. The headline numbers therefore describe channel-wide conditions rather than the position of any single line of trade.

Because the figures are unadjusted for price changes, part of the 19.8 percent sales gain may reflect price inflation rather than unit volume growth. The Census Bureau does not decompose the two effects in this release, so distributors comparing their own growth against the benchmark should treat the number as a nominal, not real, growth rate.

The revision history adds a note of confidence to the trend: both the sales revision (August) and the inventory revision (September) moved upward, indicating the underlying data have strengthened rather than softened on second estimation.

Going forward, the October release will show whether distributors rebuild inventories toward the historical ratio or hold lean positions — a choice that will shape gross margins, fill rates and pricing power across the wholesale channel into the fourth quarter.
