LONDON, March 10 (Reuters) - Gold fell more than 2 percent on Tuesday to below $900 an ounce as equity markets rose, denting interest in the metal as a safe store of value.
Spot gold <XAU=> fell to $898.60/900.60 an ounce at 1426 GMT from $920.95 late in New York on Monday. U.S. gold futures for April delivery <GCJ9> on the COMEX division of the New York Mercantile Exchange fell $17.80 to $900.20 an ounce.
"Gold has been unable to hold on to any intermittent gains and most rallies have been used as fresh selling opportunities," Pradeep Unni, senior analyst at Richcomm Global Services, said.
He said support at $900 had prevented an accelerated sell-off over the last couple of sessions, but breaking this zone meant gold could fall to around $885.
"The recent volatility in equity markets has been getting reflected in to the yellow metal quite vividly," he said.
U.S. equities rose sharply on Tuesday as financials led a broad run-up from 12-year lows after Citigroup <C.N> gave reassurances about its performance and investors became hopeful about efforts to stem the economic slide. <.N>
World stocks rose after three consecutive days of declines knocked them to six-year lows, with the MSCI world equity index <.MIWD00000PUS> climbing more than 1 percent. [

The dollar fell against a basket of currencies on Tuesday, retracing the previous day's gains. [

BLEAK
Analysts say the bleak global economic outlook and currency market volatility will support gold prices. Plunging equity markets and inflation fears pushed the metal to an 11-month high above $1,000 an ounce last month.
Swiss bank UBS -- using an econometric model based on volatility in inflation levels, a dollar index and inflation as measured by U.S. CPI -- said it sees an upside limit for gold of $2,500 an ounce and a floor of $500. [

"The past week's reports from the physical gold markets of India and China and last week Turkey also were anything but positive as far as jewellery demand is concerned," precious metals trading house Heraeus said in a weekly note.
Gold demand in India was quiet on Tuesday as banks closed for a public holiday. [
]Falling jewellery demand was offset by strong buying for gold-backed exchange-traded funds earlier in the year. That, however, has stalled.
The SPDR Gold Trust's holdings have remained relatively steady in the last two weeks. In comparison, they jumped by some 200 tonnes in the first six weeks of the year. [
]Among other precious metals, spot silver <XAG=> slipped to $12.59/12.66 an ounce from $12.92. Spot platinum <XPT=> fell to $1,035/1,040 an ounce from $1,058, while spot palladium <XPD=> was little changed at $194/199 an ounce from $194.
Both platinum group metals have suffered from fears the recession will curb demand from carmakers, the major buyers of the metals used in catalytic converters, and jewellers. (Editing by Sue Thomas)
