The U.S. economy expanded at a "modest to moderate" pace in most of the country between early July and late August, according to a Federal Reserve's Beige Book, its region-by-region assessment of the economy, suggesting that the economy is reaching the point where the central bank could pull back on its asset-purchase program.

San Francisco Fed President John Williams said the central bank should start to trim its bond-buying program later this year and end it mid-2014, as long as the job market continues to heal and inflation heads back up toward 2 percent.

Meanwhile, President Obama urged lawmakers to approve his plan for a military strike on Syria during a news conference in Stockholm, adding the "international community's credibility is on the line." Obama's remarks came a day before the G-20 summit in St. Petersburg, hosted by Vladimir Putin. Obama said he held out hope that the Russian president would back away from his support for Assad.

U.S. Senate foreign relations panel passed authorization for use of military force in Syria. The vote by the panel clears the way for a vote on the resolution in the full Senate, likely next week.

"The non-farm payrolls report for August released on Friday will likely prove far more crucial (than Wednesday's data), given the importance of labor market conditions and as such will likely generate a much greater reaction in financial markets," wrote Bank of Tokyo-Mitsubishi's Lee Hardman.

Ford Motor advanced after the automaker posted sales that climbed 12 percent from a year ago, logging its best month since August 2006. General Motors also rose after the company posted sales that jumped almost 15 percent. And rival Toyota posted August sales that surged nearly 23 percent.
