WASHINGTON DC, United States

US businesses at the wholesale level trimmed their stockpiles in November for the first time in nearly a year, even though sales rose for a fifth consecutive month.

The Commerce Department says wholesale inventories dipped 0.2 per cent in November, the first decline since December 2009. Sales rose 1.9 per cent after a 2.6 per cent surge in October — the largest monthly gain since March.

Companies had increased their inventories for 10 straight months before they dipped in November to a level of US$425.5 billion. Even with the decline, wholesale stockpiles are 10.1 percent above the lowest point since the recession began — US$386.3 billion in September 2009.

Businesses had US$455.6 billion worth of inventories in August 2008 when sales began to plunge. They responded by cutting back to control costs.

The latest drop in inventories came as a surprise to economists. They had expected another increase. It will likely be viewed as a temporary setback and not the start of a trend in cutting back on stockpiles.

Strong gains in both inventories and sales have been good news for many industries, which have been able to boost production and hire more workers over the past year.

Economists believe that businesses will keep boosting their stockpiles as long as sales continue to rise. Retailers enjoyed the best holiday shopping season in four years and auto sales have been rising in recent months.

Economists are hoping that the tax-cut package approved by Congress in December will provide further support to consumer spending in the coming year. It includes a cut in Social Security payroll taxes, leaving a household earning US$50,000 a year with another US$1,000 to spend.

For November, the drop in wholesale inventories reflected declines in stockpiles of electrical equipment, drugs, food and furniture. Stockpiles of autos, metals, hardware and machinery all rose.
