NEW YORK, Feb 4 (Reuters) - Gold posted its biggest one-day loss since 2008 on Thursday, hitting a three-month low as a wave of risk aversion swept through global markets, triggering massive technical selling in the metal.
Bullion tumbled more than 4 percent in heavy trade, briefly falling below $1,060 an ounce as escalating sovereign debt fears in Europe prompted investors to bid up the dollar and unload riskier assets.
Other precious metals also fell. Silver slid nearly 7 percent to its lowest since September, platinum dropped more than 4 percent and palladium fell 6 percent.
Scott Meyers, senior analyst at Pioneer Futures, a unit of MF Global, said gold has slid below technical support levels.
"There is not a lot of technical support in gold right now. It is more of a function of how the market reacts to whatever stimulus is forcing the market lower right now," Meyers said.
Risk-averse economic sentiment pummeled world stock markets, pressuring gold, oil and other commodities.
Wall Street fell more than 3 percent on an unexpected increase in the number of Americans claiming jobless benefits, and as fiscal worries in euro-zone countries led investors to buy safe-haven U.S. Treasury debt. [
]Spot gold <XAU=> hit a low of $1,059.10 an ounce, the weakest since Nov. 3. It was last at $1,064.30 an ounce at 4:07 p.m. EST (2107 GMT), sharply lower than $1,108.85 late on Wednesday.
Spot bullion's 4.2 percent decline was its biggest one-day percentage loss since Dec. 1, 2008, when it tumbled 5.6 percent, Reuters data showed.
U.S. gold futures for April delivery <GCJ0> settled down $49 at $1,063 on the COMEX division of the NYMEX.
"If you are short, you stay short, because there is no real reason to be a buyer unless the market sold off more," said Rick Bensignor, chief market strategist at broker-dealer Execution LLC.
The euro plunged to a seven-month low against the dollar. European Central Bank President Jean-Claude Trichet predicted many members in the bloc will have large, sharply rising fiscal imbalances. [

Among other commodities, oil prices fell nearly $4 to about $73 a barrel amid a global sell-off, as Reuters-Jefferies CRB index <.CRB> also fell 2.5 percent.
TECHNCIALLY VULNERABLE
The sharp decline sent spot gold well below its 14-, 50- and 100-day moving averages. Technical analysts said gold could fall further after the sell-off pushed it below major support levels, but it should hold above $1,000 an ounce. [

"This is a broken chart, at least short term. Unless tomorrow's job numbers somehow change the entire picture on the dollar and gold turns around, I am in the bear camp here," Bensignor said.
The world's largest gold-backed exchange-traded fund, New York's SPDR Gold Trust <GLD> on Wednesday reported its first outflow this month. Its holdings declined 1.6 tonnes that day, after falling 21.7 tonnes in January. [
