UPDATE 1-U.S. consumer spending rises, but saving slows
* Consumer spending rises 0.8 pct in September
* Inflation-adjusted spending up 0.4 percent
* Income gains 0.4 percent, real disposable income flat
WASHINGTON, Oct 29 (Reuters) - U.S. consumer spending rose solidly in September as households stepped up purchases on automobiles and a range of other goods, but the increase came at the expense of savings.
The Commerce Department said on Monday consumer spending rose 0.8 percent, the largest increase since February, after an unrevised 0.5 percent gain in August.
Economists polled by Reuters had expected spending, which accounts for about 70 percent of U.S. economic activity to increase 0.6 percent in September.
When adjusted for inflation, consumer spending increased 0.4 percent after edging up 0.1 percent the prior month.
Financial markets showed little reaction to the data. U.S. stock markets will be closed on Monday, and possibly on Tuesday, as a mammoth storm threatens the U.S. East Coast.
The figures were incorporated in last Friday's third-quarter gross domestic product report. Consumer spending increased at a 2 percent annual pace in the third quarter after rising at a 1.5 percent pace the prior period.
That helped to lift economic growth at a 2 percent rate during the quarter, an acceleration from the April-June period's 1.3 percent pace.
The spurt in spending as the quarter ended, which was concentrated in long-lasting goods such as autos and Apple Inc's iPhone 5, suggests some of the momentum could carry through the remainder of the year. However, challenges remain.
While overall income last month grew 0.4 percent, the most since March and a step-up from August's 0.1 percent, the amount of money at the disposal of households after accounting for inflation and taxes was flat.
That meant households cut back on saving to fund purchases. This and sluggish job growth could hamper spending over the long-term. The saving rate slipped to 3.3 percent last month, the lowest since November 2011, from 3.7 percent the prior month.
``Households were only able to boost consumption in the third quarter by dipping into their savings,'' said Paul Dales, senior U.S. economist at Capital Economics. ``Faced with the prospect of major tax hikes in the New Year, however, they will soon become more cautious.''
