BENGALURU, Dec 21 (Reuters) - Gold steadied on Friday near the previous session's six-month high as volatility in equity markets and concerns about global growth kept interest in the safe-haven assets firm.
Spot gold XAU= was flat at $1,259.37 per ounce at 1412 GMT, after jumping 1.3 percent in the previous session to hit its highest since June 26 at $1,266.40.
U.S. gold futures GCv1 fell 0.4 percent to $1,263.50 per ounce.
"The risk-off environment and expectations for a slowdown next year should be supportive for gold," said Craig Erlam, an analyst at OANDA, adding that a bounce in the U.S. dollar had taken the edge off gold's recent rally.
Gold has risen about 1.8 percent so far this week. The metal, which draws investors during times of political, economic and financial uncertainty, is headed for its best quarter since March 2017, up 5.7 percent.
"Falling stock markets and higher market volatility appear to be key to whether gold can extend its rally," Societe Generale (PA:SOGN) analyst Robin Bhar said in a note.
Gold is trading above its 200-day moving average of around $1,252 an ounce, which analysts said was a bullish signal.
The U.S. Federal Reserve's commitment to retain the core of its plan to tighten monetary policy has rattled stock markets and has put pressure on the dollar recently, making bullion more attractive. MKTS/GLOB USD/
