Spot gold was last down 0.3 percent to $1,239 an ounce, after a 2 percent drop overnight. U.S. gold futures for April delivery settled $2.60 lower at $1,239.80 an ounce, down 1.9 percent on the week after five straight weeks of gains.
But January's early strength was enough to push gold to its first monthly rise in five. The metal rose about 3 percent for the month.
"The market is struggling to break above the $1,275 level or below $1,225, and I think we will stay around these levels again next week as market participants position themselves ahead of the U.S. nonfarm payroll numbers,'' said Afshin Nabavi, head of trading at MKS SA.
The dollar index was up 0.2 percent on the day, close to a one-week high hit on Thursday. Global shares fell as they struggled to shake off the difficulties that have spread from emerging markets.
"You have strength of the dollar against emerging markets currencies, and that's negative for gold,'' said Quantitative Commodity Research owner Peter Fertig.
