(Adds trader comment, second byline, dateline, updates market activity) NEW YORK/LONDON, Oct 30 (Reuters) - Gold fell in choppy trade on Wednesday, erasing earlier gains, as investors took profits after the Federal Reserve said it will keep its bond-buying stimulus and offered few surprises. In its October policy statement, the U.S. central bank said it will keep buying $85 billion in bonds per month for the time being, as Fed officials nodded to a weaker growth outlook due in part to a fiscal fight in Washington that shuttered much of the government for 16 days earlier this month. "The expectation of Fed tapering further down the road has already been factored into the gold market, and its comment about moderate growth and no inflation triggered some selling," said Frank McGhee, head precious metals dealer at Chicago commodities brokerage Alliance Financial LLC. The Fed's comments about the U.S. economy continued to expand at a moderate pace and lower-than-expected inflation weighed down on gold, traders said. U.S. Treasury prices and the S&P 500 equities index also fell, while the U.S. dollar rose against a basket of major currencies. Spot gold was down 0.2 percent to $1,340.84 an ounce percent to a session high of $1,359.60. U.S. gold futures for December delivery settled up$3.80 an ounce at $1,349.30 prior to the Fed announcement. The Fed shocked financial markets last month by opting not to scale back its bond buying, after allowing a perception to harden over the summer that it was ready to start easing off on stimulus. Its caution has since been vindicated. Gold surged more than 4 percent when the Fed Open Market Committee released its previous policy statement on Sept. 18. Silver outperformed gold, edging up 0.2 percent to $22.56 an ounce, having hit a one-month high of $23.06 earlier on Wednesday. Platinum rose 0.3 percent to $1,464.74 an ounce, while palladium eased 3 cents to $743.97 an ounce.
