(Reuters) - Gold prices firmed on Wednesday above the key psychological level of $1,800 on a weaker dollar, though gains were curbed by investor caution ahead of a Federal Reserve meeting that could offer clues on the U.S. central bank's policy tapering plans.
Spot gold was up 0.4% at $1,806.00 per ounce, as of 0328 GMT.
U.S. gold futures rose 0.4% to $1,806.90.
"Gold is benefiting from some risk-hedging buying by investors ahead of tonight's FOMC (Federal Open Market Committee) meeting outcome,".
