WASHINGTON (Reuters) - U.S. consumer spending failed to rise in May, breaking 10 straight months of gains, as households struggled with rising prices and automakers could not deliver some popular models due to fallout from Japan's earthquake.
When adjusted for inflation, spending slipped 0.1 percent, the Commerce Department said on Monday. It was the second consecutive monthly drop on that basis.
The report, which confirmed that underlying inflation had quickened, suggested consumer spending would offer little support to the economy in the second quarter. In the first three months of the year, it advanced at a modest 2.2 percent annual rate, held back by the weak U.S. labor market.
"This is in line with our expectation for very weak consumer spending for the second quarter," said Yelena Shulyatyeva, an economist at BNP Paribas in New York. "This is the result of weak auto spending as manufacturers have less inventory and prices are higher for available models."
Disruptions to auto production because of a shortage of parts in the aftermath of Japan's earthquake left some models out of stock, including top-selling Japanese cars, and encouraged carmakers to lift prices.
BNP Paribas is expecting consumer spending, which accounts for around 70 percent of U.S. economic activity, to grow at just a 0.5 percent annual rate in the April-June period.
The U.S. recovery braked sharply at the start of the year, with the economy growing at a 1.9 percent pace in the first quarter.
Forecasters see second-quarter growth at around 2 percent, but caution risks are tilted to the downside. Many are waiting for May trade data next month to get a clearer picture.
"The trends are continuing with some level of growth, but very slow levels of growth and there is nothing I see on the horizon that's going to change that," John Barbour, chief executive of educational toy maker LeapFrog Enterprises Inc, said at the Reuters Global Consumer and Retail Summit.
AUTOS WEIGH ON SPENDING
Spending on durable goods meant to last three years or more fell 1.5 percent after being flat in April. Motor vehicle sales in May set their lowest rate since September.
While the data is the latest indicating a trend of a loss of economic momentum, improvements in auto production and lower gasoline prices should lift spending and growth in the third quarter.
Gasoline prices have dropped 39 cents from a peak of $4.02 a gallon in early May, government data showed on Monday, and, in a sign of an easing of disruptions to auto production, the Chicago Federal Reserve's Midwest factory index rose in May.
"We doubt the economy's engines are getting ready to go into reverse here," said Chris Rupkey, chief financial economist at the Bank of Tokyo-Mitsubishi UFJ in New York.
A series of other regional factory reports for June, including one from the Dallas Fed on Monday, have economists looking for a soft but positive reading on national manufacturing from the Institute for Supply Management on Friday.
U.S. financial markets were little moved by the data. Stocks on Wall Street snapped back from three days of losses on bets of a near-term resolution to some of Greece's fiscal troubles, with the Standard & Poor's 500 index ending up nearly 1 percent.
Prices for government debt fell after a poor auction, while the dollar was weak against a basket of currencies.
CORE PRICE PRESSURE
While gasoline prices are retreating, underlying inflation pressures continue to percolate. The core personal consumption expenditures price index -- which excludes food and energy costs -- rose 0.3 percent in May, its largest gain since October 2009, the consumer spending report showed.
Rising inflation could put the central bank in a difficult position should growth not pick up as expected in the second half of the year. The Fed's most recent monetary stimulus, $600 billion worth of government bond purchases, wraps up on Thursday.
Incomes in May rose 0.3 percent for a second month, but disposable incomes adjusted for inflation edged up just 0.1 percent. With spending weak, savings rose to an annual rate of $591.1 billion from $568.0 billion in April.
