The stock of unsold goods held by wholesalers. Wholesalers act as intermediaries between manufacturers or importers, and retailers. Wholesalers sell directly to retailers, who strive to act in accordance (ideally) with consumer demand. Consequently, high Wholesale Inventories indicate that unsold goods are piling up, suggesting that retailers are facing lagging consumer demand and unwilling to purchase goods. Conversely, declining Wholesale Inventories suggest retailers are buying more goods to meet strong or rising demand. Because Wholesale Inventories reflect the demand retailers have for their manufacturers' wares, the report offers an early indication of the potential strength of consumer spending.

The actual inventories of crude oil, gasoline, and distillate, such as jet fuel, as reported on a weekly basis. The numbers are watched closely by the energy markets, and if the results differ greatly from the expected inventory levels, the market can react strongly. The inventory data can be skewed by holidays and seasonal factors. Weekly data can be unreliable and should be viewed as a part of longer-term trends, so a four-week moving average may be more useful.
