Gold slid more than 1.5% to hover near a nine-month low on Wednesday as elevated US Treasury yields and a stronger dollar hammered the non-yielding metal's appeal.

Spot gold was down 1.6% at $1,710.71 per ounce by 10:04 a.m. ET (1504 GMT), having dropped to its lowest since June 15 at $1,706.70 on Tuesday.

US gold futures lost 1.4% to $1,709.70.

"As real rates continue to rise, that's challenging gold. The rates markets are also adding pressure on valuations for all asset classes, and as a result, gold is a casualty," said TD Securities commodity strategist Daniel Ghali.

Benchmark US 10-year Treasury yields crept back towards a one-year peak reached last week, while the dollar rose 0.3%.

Hopes of a quick economic rebound fuelled by a swift rollout of COVID-19 vaccines also prompted an outflow of safe-haven assets like gold from investors' portfolio.

Progress on the $1.9 trillion US stimulus bill has offered little respite to gold, as higher yields have threatened its appeal as an inflation hedge by increasing the opportunity cost of holding bullion.

"The outlook for gold is tied really to whether or not we've reached that pivot point at the US Federal Reserve in terms of whether they would address the steepening of the yield curve. But we're still early in that process, so that has negative short term implications on gold," Ghali said.

Fed officials have reiterated that U.S. interest rates will remain low but citied a recent rise in real rates as a sign of growing optimism about an economic recovery.

We anticipate recent headwinds to intensify again into the second half of this year, particularly as greater US stimulus raises the prospect of an earlier than planned Fed rate hike," UBS analysts wrote in a note.

Silver fell 2.5% to $26.09 an ounce, platinum slipped 2.1% to $1,179.50. Palladium rose 0.7% to $2,378.50.
