Spot gold fell 0.3 percent to $1,127.70 an ounce at 0641 GMT, after climbing to a two-week high of $1,133.20 in the previous session. Still, the metal was on track to snap a three-week losing streak with a near 2-percent gain.
The Fed kept interest rates unchanged on Thursday, in a bow to worries about the global economy, financial market volatility and sluggish inflation at home. But the US central bank maintained its bias towards a rate hike sometime this year.
Gold had been weighed down all year on uncertainty over when the Fed would hike interest rates from record-lows. Higher rates could dent demand for non-interest paying bullion, while boosting the dollar.
Weakness in the dollar and stock markets could prompt a rally in gold prices in the near term but the gains are unlikely to last, said INTL FCStone analyst Edward Meir.

"Because the Fed has made clear that it intends to raise rates by year-end, the markets will eventually start bidding the dollar higher and we could see gold's up move to be relatively short-lived," he said.
The Fed on Thursday also forecast inflation would creep only slowly toward its 2 percent target, which one bullion trader said was a negative for gold, often seen as an inflation-hedge.
