Minutes before the announcement, spot gold traded up 0.56 percent at $1,249.86. After the Fed's announcement, gold fell briefly, trading down 0.19 percent by 2:02 PM ET, but tried for a rebound, last up 0.2 percent.
Earlier in the day, gold rose for a third straight session as weaker than expected U.S. data weighed on the dollar ahead of the Federal Reserve's monetary policy decision.
Data on Tuesday showed orders for long-lasting U.S. manufactured goods rebounded far less than expected in March, suggesting that business spending and economic growth were weak in the first quarter. Another report showed an ebb in consumer confidence in April. The U.S. central bank raised rates in December for the first time in nearly a decade.
Gold is highly sensitive to rising interest rates, which lift the opportunity cost of holding non-yielding bullion while boosting the dollar, in which it is priced.
Bullion has rallied 17 percent this year on speculation that the Fed might not raise rates this year amid uncertainty over the global economy.
A slump in demand from key Asian consumers is likely to push gold prices lower in the short term, GFMS analysts at Thomson Reuters said in a report on Tuesday.
Global gold demand tumbled by 24 percent year on year to 781 tonnes in the three months to March 31, its weakest quarter in seven years, GFMS said.
