Wall Street stocks fell on Wednesday as possible U. military action against Syria stoked investor concerns about geopolitical risk to the American economy and minutes from the Federal Open Market Committee sparked worries about a more hawkish view on interest-rate increases.

The rising tensions sent oil prices surging, boosting energy stocks 1 percent. But the risk-off sentiment weighed on Treasury yields <US10YT=RR>, pushing financial stocks down 1.3 percent.

"There's general nervousness about what might happen with any strikes and the potential escalation of tensions with Russia," said Anwiti Bahuguna, senior portfolio manager at Columbia Threadneedle Investments in Boston.

The major Wall Street indexes edged even lower after minutes from the Federal Open Market Committee showed concern among a few of its members that rising inflation might require a faster pace of interest rate hikes than anticipated.

Members of the Federal Reserve voted unanimously to raise borrowing costs by a quarter percentage point and expressed confidence that the economy would strengthen and inflation would rise in coming months.

"The minutes were modestly negative," said John Carey, portfolio manager at Amundi Pioneer Asset Management in Boston. "People had been speculating that due to all the turbulence in the market because of geopolitical uncertainties that the Fed might consider pausing or slowing down the interest rate increases."

The Dow Jones Industrial Average fell 218.55 points, or 0.9 percent, to 24,189.45, the S&P 500 lost 14.68 points, or 0.55 percent, to 2,642.19 and the Nasdaq Composite dropped 25.28 points, or 0.36 percent, to 7,069.03.

Investors said they are looking to earnings season to provide a sustained boost to U.S. stocks. Banks JPMorgan Chase & Co , Citigroup Inc and Wells Fargo & Co will report quarterly results on Friday.

Analysts expect quarterly profits for S&P 500 companies to rise 18.5 percent from a year ago, which would be the biggest gain in seven years, according to Thomson Reuters I/B/E/S.

Industrial distributor Fastenal fell 6.2 percent after its earnings missed expectations. The stock was the biggest decliner on the S&P, followed by industry peer WW Grainger's 4.4 percent drop.
