Gold prices eased on Monday as the rollout of a COVID-19 vaccine lifted riskier assets, overshadowing expectations of more US fiscal and monetary stimulus.

Spot gold fell 0.2% to $1,836.08 per ounce by 0303 GMT, while US gold futures eased 0.2% to $1,839.90.

"The euphoria around a COVID-19 vaccine will likely overshadow further easing from the Federal Reserve and a fiscal relief package in the near term," said Howie Lee, an economist at OCBC Bank.

"But gold could rally in 2021 when the vaccine optimism dies down and investors' focus returns to rising inflation expectations due to the large swathe of monetary and fiscal stimulus the US economy still requires."

The first shipments of Pfizer Inc and BioNTech SE's

approved coronavirus vaccine in the United States began on Sunday, raising hopes for a faster economic recovery and lifting Asian equities.

But gold's losses were limited by hopes of further US fiscal stimulus, with Reuters reporting that a $908 billion relief plan will be split in two in an effort to win approval and could be introduced as early as Monday.

A leading Democrat lawmaker also suggested his party might be willing to reach a compromise on the relief package.

Gold, considered a hedge against inflation and currency debasement, has gained 21% so far this year on the back of near-zero interest rates and unprecedented global stimulus.

Speculators raised their bullish positions in COMEX gold and silver contracts in the week to Dec. 8, the US Commodity Futures Trading Commission (CFTC) said on Friday.

Silver rose 0.2% to $23.97 an ounce, while platinum gained 0.8% to $1,017.34 and palladium gained 0.4% to $2,328.74.
