SINGAPORE, Nov 12 (Reuters) - Gold fell more than one percent on Friday in a broad retreat triggered by a stronger dollar, talk about Irish sovereign debt at the G20 summit and speculation China may again hike interest rates to tame inflation.
Spot gold lost as much as 1.9 percent to $1,382.99 an ounce, and recovered slightly to $1,383.35 by 0536 GMT, piercing below a 10-day moving average of $1,383.60. Spot silver <XAG=> fell more than three percent to $26.65 an ounce, and was trading at $26.76, on course for a third consecutive week of gains.
"Everyone is watching the G20, and gold is chasing the dollar," said Ronald Leung, a physical dealer at Lee Cheong Gold Dealers in Hong Kong, "We can see some consolidation from here, in a range of $40 dollars below $1,420." [
]Metals, grains and oil sold off broadly on Friday on worries about a possible new round of Chinese monetary tightening, and a weaker euro linked to fears about Ireland's ability to meet debt obligations and the temptation to cash in on gains.
Chinese consumer price inflation rose a faster than expected 4.4 percent in October, a 25-month high.
"The rumor that China will raise interest rates has been circulating this week," said Sun Lei, a metals analyst at Galaxy Futures in Beijing.
Also weighing on gold was strength in the dollar, which rose to a five-week high against a basket of currencies <.DXY>, as the euro hit six-week lows on the dollar on Friday. [
]"If the inverse correlation between the dollar and gold strengthens, we can see the dollar weigh on gold again," said Ong Yi Ling, an analyst at Phillip Futures.

But the fall is unlikely to be sharp, traders said.
"I think gold will find a base soon, as there is some physical buying at this level," said a Singapore-based trader, expecting the support level at $1,390.
Platinum group metals also fell sharply, with platinum <XPT=> falling nearly three percent to a one-week low of $1,704.75 and palladium down nearly 3 percent to $689.5.
Palladium in headed for a 1.3 percent weekly rise, stretching the winning streak to nine weeks.
The Relative Strength Index, an indicator of trade interest, on all precious metals fell below 70, above which is seen as the overbought territory. RSI on platinum fell to 50.27, its lowest in more two months.
Industrial metals also fell broadly, with Shanghai copper and zinc futures touching daily downside limits and London copper slip over two percent. [
