NEW YORK, Dec 30 (Reuters) - Gold eased on Thursday but prices are still on track to post their biggest yearly rise in three years for a record 10th consecutive annual gain on uncertainty about economic recovery and currencies.
Silver and palladium, easily the top performing commodities of the year, also hit multi-year highs on bullish demand expectations for next year.
This year, bullion has benefited from safe-haven buying on lingering worries about a euro zone debt crisis, a $600 billion U.S. bond-buyback program and renewed demand from global central banks, which are expected to become net buyers for the first time in decades.
"The economy is still on life support, and it's only moving forward based on the stimulus and Fed's action. In absence of those, we would still be down on recession," said Frank McGhee, head precious metals trader of Integrated Brokerage Services in Chicago.
"If the economic picture turns brighter and you see the Fed starting to take some of the liquidity out, then gold prices could retreat as investors think the market has already priced in what's out there," he said.
On Thursday, gold dropped after upbeat U.S. data, including jobless claims, factory data and home sales buttressed the view the economy gained momentum as the year ended. [
]Spot gold <XAU=> slipped 0.4 percent to $1,404.80 an ounce at 1:52 p.m. EST (1852 GMT). Bullion set a record high of $1,430.95 on Dec. 7.
U.S. gold futures for February delivery <GCG1> settled down $7.60 an ounce at $1,405.90.
The dollar dropped against a basket of currencies in a mixed session after having risen earlier on concerns about the euro zone debt crisis.
In 2011, the greenback is expected to continue to stay weaker in a low U.S. interest rate environment due to the Fed's accommodative monetary policy, said McGhee.
COMEX gold volume was slightly above 60,000 lots, two-thirds lighter than its average for the past 30 days but in line with lower turnover for most of the commodity complex, preliminary Reuters data showed, as many traders have already closed their books ahead of the new year.
The gold price is set to gain 28 percent, its strongest yearly performance since a 31 percent rise in 2007 when the global financial crisis began to manifest itself.
The euro zone debt crisis, which unfolded in April this year and culminated in multibillion euro international bailouts for both Greece and Ireland, has been one of the prime drivers of investment demand for gold.
Spot silver <XAG=> eased 0.2 percent to $30.49, having earlier hit a 30-year high at $30.88. The gold/silver ratio, which denotes each metal's relative performance, reached a four-year low.
"These last few days it seems as if silver has been the main driver and gold is just trotting along with a lack of sellers," said Saxo Bank senior manager Ole Hansen.
"Once something has a firm trend established, it's easy to push ... There has to be a story behind it to justify it; otherwise you would have seen profit-taking setting in a while back," he added.
Silver is at its highest since early 1980 and on course for an 83 percent gain this year, its strongest performance in at least 27 years.
SILVER LINING
Investors have flocked into silver this year as a cheaper safe-haven alternative to gold, which hit a record high of $1,430.95 an ounce in early December.
Holdings of silver in the iShares Silver Trust <SLV>, the world's largest exchange-traded fund backed by physical silver, have risen to 10,903.34 tonnes, from 9,492.97 tonnes at the end of last year, while open interest in U.S. silver futures has risen by 8,801 contracts, or 44.0 million ounces.
Holdings of gold in the SPDR Gold Trust <GLD>, the world's largest exchange-traded fund backed by physical bullion, have risen 15 percent this year to 1,284.062 tonnes, and a near 20 percent rise in open interest in U.S. gold futures also reflects some of this investor desire to hold gold. [
] <0#CFTC>Palladium was set for a second year of gains, having almost doubled to near $800 an ounce over the course of 2010 and is this year's top performing commodity.
Analysts widely expect a surge in demand for palladium next year, mainly from China, which boasts the world's largest auto market that is dominated by gasoline-powered vehicles, which use palladium in their catalytic converters.
In the United States, December is expected to be the third straight month of strong auto sales, capping a year of gradual recovery for the sector. [
]The ratio of platinum to palladium, used to measure how many ounces of palladium is used to buy an ounce of platinum, has fallen to its lowest in about eight years this year, mirroring palladium's outperformance over platinum, which relies heavily on the flagging European car market as a source of industrial demand.

Spot palladium <XPD=> eased 0.7 percent to $784.72, while platinum <XPT=> dipped 0.7 percent to $1,747.25. Prices at 2:35 p.m. EST (1935 GMT)
