In June, companies boosted their stockpiles of furniture, lumber, computer equipment, and steel and other metals. But auto inventories fell, even as sales jumped. That suggests automakers will need to keep cranking out cars to meet strong demand.
The report shows that inventory levels are roughly in line with sales. That means wholesalers likely haven't gone too far in restocking their goods. As a result, they probably won't have to slow restocking in the coming months.
Slower rebuilding of inventories can drag on growth. That's because it means fewer orders for factory goods.
That is what happened in the first three months of the year, when a big downshift in inventory building subtracted 1.2 percentage points from the economy's growth. The economy contracted at a sharp 2.1 percent annual rate. Harsh winter weather and a big drop in exports also contributed to the decline.
The slowdown was temporary, however. Inventory restocking contributed about 1.7 percentage points to growth in the second quarter, when the economy expanded at a 4 percent annual rate.
The report Friday covers inventories held at the wholesale level. In a later report, the government will detail inventories at the manufacturing and retail levels.
