U.S. wholesalers boosted their stockpiles in May by the largest amount in six months while sales rose by a modest amount.

    Wholesale stockpiles rose 0.8 percent, double the gain in April and the largest one-month rise since November, the U.S. Commerce Department reported Friday. Sales were up 0.3 percent in May following a 1.7 percent surge in April. That had been the biggest sales increase in more than a year.

    The strong increase in inventory building in May could be evidence that businesses are growing more confident about the future. A decision to accelerate inventory stocking would help bolster overall economic growth.

    The May rise left inventories at the wholesale level at a seasonally adjusted US$449.8 billion, 3.8 percent below a year ago.

    Economists believe sales at both the wholesale and retail levels will rebound in coming months after a slowdown in the first quarter that was caused in part by unusually frigid weather. A pickup in consumer spending, which accounts for 70 percent of economic activity, is expected to translate into stronger economic growth for the rest of the year.

    The government has already reported that retail sales accelerated solidly in May.

    The big inventory gain in May reflected larger stockpiles of autos and auto parts as well as furniture, lumber and computers.(SD-Agencies)
