Gold firmed above $1,900 an ounce on Friday, heading for a weekly gain, as the dollar weakened and as investors hedged against uncertainties surrounding the coronavirus pandemic and going into the Nov. 3 US presidential election.

Spot gold rose 0.4% to $1,911.14 per ounce by 1115 GMT and was up 0.6% for the week. US gold futures gained 0.5% to $1,914.10.

"Gold is getting some boost from the dollar weakening and we have the US elections and there's still a lot of uncertainty. Also, there are talks about the US stimulus package in negotiation," said Bank of China International analyst Xiao Fu.

The dollar index fell 0.2% against its rivals, making dollar-denominated gold less expensive for holders of other currencies.

House Speaker Nancy Pelosi on Thursday reported progress in talks with the Trump administration for another round of fiscal aid and a deal could be reached "pretty soon".

Even once the US election results were known, "there still could be uncertainty about policies and implementation running until the end of the year, in turn supporting gold," Bank of China International's Fu said.

There could also be additional inflows into gold exchange traded funds - often a gauge of investor sentiment - on renewed uncertainties over pandemic-related restrictions and the US election outcome, UBS analysts said in a note.

The final debate between US President Donald Trump and his Democratic challenger Joe Biden included contrasting views on the pandemic.

Countries across Europe implemented fresh restrictions as coronavirus cases more than doubled over the last 10 days, while the global tally touched about 41,178,000.

Silver edged up by 0.1% to $24.78 per ounce and was set for a weekly rise. Platinum gained 1.3% to $896.31 and palladium rose 0.3% to $2,381.39.
