NEW YORK/LONDON, June 18 (Reuters) - Gold edged up on Wednesday after the Federal Reserve hinted at a slightly faster pace of interest rate increases next year but slashed its forecast for U.S. economic growth this year, lifting bullion's safe-haven appeal. After a two-day policy meeting, the central bank slashed its forecast for U.S. economic growth to a range of between 2.1 percent and 2.3 percent from an earlier forecast of around 2.9 percent, but expressed confidence the recovery was largely on track. "The growth forecast reduction suggested that the Fed may not be in a hurry to accelerate tapering," said James Steel, chief metals analyst at HSBC. Spot gold was up 0.2 percent at $1,273.40 an ounce by 2:34 p.m. EDT (1834 GMT), after trading in a narrow $9 trading range.
