US gold futures rose 0.1 percent to $1,310.50 an ounce. Gold has strengthened technically after closing above 200-day and 100-day moving averages over the past two weeks, also breaching key psychological resistance at $1,300 on Friday, analysts and traders said.
Spot gold rose 13 percent last year to mark its best annual performance since 2010. A wilting US dollar, political tensions and receding concern over the impact of US interest rate hikes fed the rally. The greenback, in which gold is priced, had its worst performance since 2003 last year, damaged by tensions over North Korea, questions over Russian involvement in US President Donald Trump's election campaign, and persistently low US inflation.
"Gold has clearly benefited from lower US yields and a much weaker US dollar into the year-end and one also suspects, quite a bit of urgent short-covering in a thin market," said Jeffrey Halley, senior market analyst at OANDA.
