Gold is highly exposed to interest rates, particularly in the United States, as higher rates lift the opportunity cost of holding non-yielding assets and boost the dollar, in which gold is priced.
Spot gold was up 0.04 percent at $1,337.11 an ounce by 2:26 ET, while U.S. gold futures rose .07 percent to $1,340.90 an ounce.
"It's a mixed bag because on one side no action was taken to hike rates but at the same time the hawkish sentiment has increased and the number of officials in favor of a rate hike has increased," Capital Economics analyst Simona Gambarini said.
"Investors and markets are taking bets on a December hike and that is weighing on gold prices."
Markets will be closely analyzing upcoming U.S. data such as GDP, non-farm payrolls and inflation for clues on the direction of rates. Gambarini said this could lead to volatility in gold prices.
"The Fed have signaled that if everything stays the way it is then December is more than likely the next rate rise and this will keep a lid on any rally," David Govett, head of precious metals at Marex Spectron, said in a note.
