"It's quite clear that the money markets are factoring a very sizeable fiscal stimulus spend from the Democrats, some bounce in inflation," said Ross Norman, an independent analyst.
"So gold initially traded lower on those triggers - dollar and Treasury yields (rising) - now it's trading a little higher on anticipation of some inflation to come."
