Gold rose on Friday ahead of a closely watched U.S. jobs report and the metal was set to post its first gain in four weeks thanks to safe-haven bids amid political uncertainty in Greece plus robust Chinese demand.
Spot gold ticked up 0.3 percent to $1,212.21 an ounce by 0308 GMT but it was below a three-week high of $1,222.40 reached on Tuesday.
"Safe-haven demand appears to be rising again as oil prices slump and concerns grow about Greece exiting the euro," ScotiaMocatta analysts said in a note, adding that physical demand in top consumer China had also been a factor. "We are wary that the safe-haven buying may not last if concerns over Greece subside."
The metal has gained 2 percent so far this week, snapping a three-week losing streak, after global equities slumped on worries over political developments in Greece that could see it leaving the euro zone. Equities have since recovered, prompting gold to give up some of its gains. Strong U.S. economic data has also hurt.
The latest safe-haven bids were spurred by concerns that a Jan. 25 Greek general election would lead to a stand-off between Berlin and Athens over austerity policies imposed on Greece.
Traders were waiting for the release of the U.S. nonfarm payrolls report later in the day to gauge the strength of the world's biggest economy. Robust data would dent gold's appeal as a hedge. Strong data could also prompt the Fed to increase interest rates sooner rather than later, hurting non-interest-bearing bullion.
