Globally gold held firm near an all-time high on Monday, inching closer to a key $3,600 level, bolstered by mounting expectations of a U.S. Federal Reserve rate cut this month following a weaker-than-expected jobs report last week, Reuters reported.
Spot gold was flat at $3,586.81 per ounce. Bullion rose to a record high of $3,599.89 on Friday.
"The main driver is U.S. jobs data and the expectations now that the Fed could cut by 50 basis points in September. It's a marginal chance but a material shift from before the jobs figures," Capital.com financial market analyst Kyle Rodda said.
"Basically...all of the tailwinds are blowing for gold at the moment and notwithstanding an inflation shock this week, we will make a good test of $3,600."
