Gold rose more than half a percent on Monday after firm oil prices prompted safe haven buying from investors and speculators, while technical buying also resurfaced after bullion bounced from its weakest level in two months.
But gains may be capped by worries that a plan by main consumer India to double its import duty could cause a temporary slip in purchases. Silver tracked gold higher, while platinum prices stayed at premiums to bullion on supply concerns.
Gold added $9.35 to trade at $1,662.84 an ounce after posting a 3% fall last week in its second-biggest weekly decline this year, on fading expectations of more monetary easing in the United States.

"You can see there's short-covering. I think it's technical. The upside will be at $1,675 to $1,680, and there will be some resistance there," said Ronald Leung, director of Lee Cheong Gold Dealers in Hong Kong.
"Gold wants to break test these levels, but if it can't, it will go back to $1,600 again. Let's see what happens to the market after the increase in India's duty."

US crude oil futures extended gains on Monday on continuing tensions over Iran's disputed nuclear programme and the potential for supply disruptions in the region, which raised fears of inflation.
But a firm dollar and equities still weighed on gold as an improving economic outlook in the United States prompted some investors to shift their money back to riskier assets.

In Singapore, dealers waited for Indian gold jewellers to re-enter an otherwise dull physical market.
"I see some light selling from Thailand. It's very light. I would think some people are waiting for prices to go down to the $1,650 level," said a dealer in Singapore, referring to demand from jewellers.
Many Indian families buy gold as an investment in a climate of high inflation and crimped real interest rates. Gold is also an integral and important part of weddings, often representing the wealth of a bride and acting as her security.
