Gold futures posted the longest slump in five weeks on concern that the Federal Reserve is moving closer to raising U.S. interest rates, crimping demand for the precious metal as an alternative investment.

In the third quarter, gold fell 8.4 percent as the U.S. economy gained. The Fed begins a two-day meeting tomorrow and policy makers will debate the pace of raising borrowing costs after holding its benchmark rate close to zero percent since 2008.

Last month, gold dropped to a four-year low as equities surged to a record and oil prices entered a bear market. Jeffrey Currie, head of commodity research at Goldman Sachs Group Inc, said last week that the metal will drop as the U.S. economy improves. Economists and Fed officials surveyed by Bloomberg expect higher rates in 2015.

Gold futures for February delivery fell 1.2 percent to close at $1,207.70 an ounce at 1:46 p.m. on the Comex in New York. The price capped a fourth straight decline, the longest slump since Nov. 6.
