NEW YORK, Nov 3 (Reuters) - Gold and silver prices fell about 2 percent on Wednesday, hit by heavy liquidation in New York metals futures, ahead of an expected announcement on monetary policy from the Federal Reserve.
Both gold and silver were on track to post their biggest one-day fall since Oct. 21.
Prices came under pressure from a firmer dollar in earlier trade but held in a fairly narrow range as traders awaited news about how much U.S. government debt the U.S. central bank will buy under a second round of so-called quantitative easing since the financial crisis began in 2008.
The bank's Federal Open Market Committee was due to make a statement at around 2:15 p.m. EDT (1815 GMT), at the end of a two-day policy meeting.
Gold futures on the COMEX division of the New York Mercantile Exchange lost as much as 2 percent, while silver futures fell more than 3 percent in earlier trade.
The metals slumped on "nervous liquidation prior to the FOMC meeting results. That's all it is," said George Nickas, a gold broker at FC Stone in New York. "There is no clear picture (as to) what the market is going to look like by the end of the day."
Spot gold <XAU=> slipped to a low of $1,327.80 an ounce and was down 1.3 percent at $1,340.05 an ounce at 1 p.m. EDT (1700 GMT). U.S. gold futures for December delivery <GCZ0> eased $23.60 an ounce to $1,333.30.
Silver <XAG=> fell 2.1 percent to $24.38 an ounce, having hit a low of $23.93 in earlier trade.
"It is all about last-minute profit taking before QE2," said Saxo Bank analyst Ole Hansen. "Stops had been building up below $1,350 over the last couple of days and, once that went, it was all over.
"This move leaves the market in a much better position to react to (bullish) gold news after the Fed," he added.
A Reuters poll found on Wednesday that most leading economists expected the Fed to buy between $80 billion and $100 billion worth of assets per month under a new program to bolster the struggling economy. [
]Estimates for how much the Fed would spend overall varied from $250 billion to $2 trillion.
Macquarie analyst Hayden Atkins said the initial euphoria over QE and its potential impact on gold had largely worn off, and, while the metal may see some support if the policy meets expectations, a major lift is unlikely.
"There may be some upside surprise but (markets) pretty quickly priced out a Big Bang policy," he added. "It might be a mild positive, but I think the reality of what could happen is in most people's minds already."
PHYSICAL DEMAND STRONG
Elsewhere wholesale physical gold demand in India, the world's biggest bullion consumer, was healthy as the country's busiest gold-buying festival, Dhanteras, got under way, with local demand helped by the strong rupee. [
]Traders and retailers expected volume to rise up to 20 percent, despite near-record prices, as customers line up to make the most of the festival. [
]Holdings of the world's largest gold-backed exchange-traded fund, New York's SPDR Gold Trust <GLD>, slipped on Tuesday, however, by around 1 tonne to 1,292.189 tonnes. ETFs issue securities backed by physical stocks of metal. [
]On the supply side of the market, the Xinhua news agency reported that China had found a 100-tonne gold deposit in Inner Mongolia, worth about $5.25 billion. China is the world's biggest gold miner, and its number two consumer. [
]Platinum <XPT=> traded down 0.9 percent at $1,692.74 an ounce, while palladium <XPD=> lost 0.6 percent to $639.22 an ounce. Prices at 1:09 p.m. EDT (1709 GMT)
