NEW YORK/LONDON, Nov 1 (Reuters) - Gold prices eased on Monday, retreating from two-week highs, as the market zeroed in on the potential outcome of this week's U.S. elections and a Federal Reserve decision on asset buying.
Both gold bullion and futures have jumped more than 15 percent since late August, hitting record highs of nearly $1,390 an ounce, as the dollar plunged on expectations that the Fed will spend billions of dollars on a second round of quantitative easing to aid economic recovery.
In Monday's session, the market rallied again, touching two-week highs. But it fell later as investors began to work on what Tuesday's U.S. Congressional elections and Wednesday's Federal Reserve policy announcement were likely to yield.
"I think, really, at this point in time, gold and almost all other commodities are focused on the elections and the Fed meeting. So, even if we talk about any other data or factors outside these, it's going to come back to these two events," said David Meger, vice president and director of metals trading at Chicago's Vision Financial Markets.
U.S. gold futures most-active contract, December <GCZ0>, settled down $7, or 0.52 percent, at $1,350.60 an ounce on the COMEX division of the New York Mercantile Exchange. It touched $1,366.40, its peak since Oct. 19, during the session.
Spot gold <XAU=>, which reflects trades in bullion, was almost flat, trading at $1,351.51 an ounce by 3 p.m. EDT (1900 GMT), versus $1,352.70 in New York late on Friday. Bullion hit $1,365.49 earlier in the session, the highest level since Oct. 19.
Bill O'Neill, partner of LOGIC Advisors in Upper Saddle River, New Jersey, said he thought gold would finish the week little changed. "My guess is for a plus/minus of $5 an ounce either way."
As of Monday, most economists expected the Fed to buy $80 billion to $100 billion in assets per month under the so-called QE2, according to a Reuters poll. Estimates of total purchases ranged from $250 billion to $2 trillion.
UNCERTAINTY OVER FED WEIGHS
The wide range showed how uncertain some investors were over the extent of the Fed easing.
Those uncertainties were partly responsible for Monday's thin volume in gold, which stood at about 122,00 lots on COMEX at midday, versus Friday's 162,000 lots. Over a 30-day average, volume in gold futures is down almost 28 percent.
A stronger dollar <.DXY> also weighed on gold prices. [
]Industrial data out of United States and China, indicating economic recovery was on track, helped the dollar rebound. The dollar has lost about 7 percent of its value over the past two months on speculation over the QE2. [
] [ ]Physical demand for gold, meanwhile, bucks any weakening price trend in the immediate term.
India, the biggest bullion consumer, has kept up strong buying of the yellow metal. The president of the Bombay Bullion Association said India's October gold imports rose to 43 tonnes, above a Reuters poll forecast of 41.5 tonnes. [
]"The Diwali religious festival takes place in India on Friday, and physical demand for gold should remain high in the run-up to this holiday," Commerzbank said in a note.
SILVER, PALLADIUM OUTPERFORM
Silver and palladium outperformed gold in Monday's session, extending their sharp run-up from last week.
Silver rose to its highest levels in 30 years, tracking gains in gold to break through $25 an ounce for the first time since 1980.
COMEX silver's December contract <SIZ0> settled down $1.20 at $24.552 an ounce, after racing to $25.055 earlier. Spot silver <XAG=> peaked at $25.03 an ounce and was later bid at $24.63 an ounce against $24.64.
But, unlike gold, physical demand for silver appeared to be tapering.
Holdings of the world's largest silver-backed exchange-traded fund, the iShares Silver Trust <SLV>, fell nearly 40 tonnes on Friday to 10,141.92 tonnes, data from the fund showed. [
]NYMEX December palladium <PAZ0> finished up more than half percent, or $3.60, at $648.70 an ounce, extending nine-year highs seen in the previous session. Spot palladium <XPD=> rose to a peak of $655 an ounce, its highest since 2001.
