NEW YORK, Dec 29 (Reuters) - Gold climbed to its highest in three weeks and silver rose toward a 30-year high on Wednesday, as thin volume and a weaker dollar drove bullion to within $20 of its record.
Gold buying was boosted as the dollar fell against the yen, euro and some commodity-driven currencies such as the Australian and New Zealand dollars. [
] Precious metals extended gains from the previous session, when bullion jumped over 1.5 percent on doubts over U.S. economic recovery."Volume is light and somebody's making a decision on whether to own some gold or to cover some short positions at the end of the year. It can change in any given time during the day," said George Nickas at futures broker FC Stone.
After several weeks of trendless trade, gold staged its biggest two-day gain since Dec. 6 as many investors bet that economic uncertainty and currency diversity would fuel more demand from investors and banks. Prices are on track to rise 28 percent this year, a record 10th consecutive annual gain.
Analysts said that Tuesday's dismal U.S. economic data with an unexpected deterioration in U.S. consumer confidence and a sharp fall in U.S. single-family home sales suggested the Federal Reserve will maintain an accommodative monetary policy in 2011.
Spot gold <XAU=> rose 0.4 percent to $1,411.49 an ounce by 12 p.m. EST (1700 GMT), having earlier setting a three-week high of $1,412.65. U.S. gold futures for February delivery <GCG1> were up $6.60 an ounce at $1,412.20.
Silver led the rally again as it has for the past few months, after setting a three-week high of $30.64 an ounce.
Spot silver <XAG=> rose 1.2 percent to $30.61, driven by a broad push higher across the commodities complex, with copper <CMCU3> at record highs and crude oil steadying above $91 a barrel. [
] [ ]The gold-silver ratio, used to measure how many ounces of silver is used to buy an ounce of gold, slumped to a new 46-month low of 46.1, extending its steady decline since August. It has averaged about 63 over the past year, and dropped below 45 only twice in the past 25 years.
Silver is one of the best-performing commodities so far this year, gaining over 80 percent.
Gold is also on track for a near 30-percent gain this year, fueled by investors seeking an alternative to increasingly volatile currencies, stocks and bonds, against a backdrop of an uncertain U.S. economic outlook and Europe's debt crisis.
"Is gold a bubble? Perhaps, but the trend is still clearly 'from the lower left to the upper right' on the charts and in all currency varieties," said Independent investor Dennis Gartman.
Gartman, at times cautious on gold's rally this year, said earlier this week he was expanding his position by buying bullion in U.S. dollar terms as central banks stock up. [
]U.S. Treasury debt prices rose with some bargain hunting after a poor auction of five-year notes on Tuesday sparked a sell-off. A sharp rise in U.S. Treasury yields on Tuesday fueled inflation concerns and added to gold buying. [

Palladium hit fresh nine-year highs, driven by expectations for robust demand next year.
Spot palladium <XPD=> reached a session peak of $793.50, its highest since March 2001. It gained 0.9 percent to $792 an ounce.
Palladium has been the top pick of a number of funds and trading houses, which have cited demand from China, the world's largest auto market, as one of the prime drivers of consumption for the metal, which is used in catalytic converters.
Platinum <XPT=> eased 0.3 percent at $1,748.70, but still near its seven-week highs. Prices at 12:16 p.m. EST (1716 GMT)
