NEW YORK/LONDON, March 10 (Reuters) - Gold prices ended sharply lower on Tuesday, falling below $900 an ounce for the first time in a month, as a sharp rally in global stock markets lessened economic fears, prompting investors to switch out of the safe-haven metal.
U.S. equities rose sharply on Tuesday as financials led a broad run-up from 12-year lows. The S&P 500 index jumped nearly 6 percent, while the Dow Jones Industrial Average added 350 points. <.N>
"The recent hopes of $1,000 gold were dashed in the last two days by investors looking to stop losses, fund liquidations and selling related to margin calls," said George Gero, vice president of RBC Capital Markets Global Futures.
Spot gold <XAU=> was at $897.30 an ounce at 3:36 p.m. EDT (1936 GMT), down 2.2 percent from its last quote of $920.95 late in New York on Monday.
U.S. gold futures for April delivery <GCJ9> settled down $22.10, or 2.4 percent, at $895.90 an ounce on the COMEX division of the New York Mercantile Exchange.
"The recent volatility in equity markets has been getting reflected into the yellow metal quite vividly," Pradeep Unni, senior analyst at Richcomm Global Services, said. "Gold has been unable to hold onto any intermittent gains and most rallies have been used as fresh selling opportunities."
World stocks rose after three consecutive days of declines, with the MSCI world equity index <.MIWD00000PUS> climbing sharply.
VOLATILE GOLD MARKET
The chief executive of Barrick Gold Corp <ABX.TO>, the world's largest gold producer, said industry supply of the metal will continue to fall and the price will remain volatile in the near term.
Aaron Regent, Barrick's CEO, told the Reuters Global Mining and Steel Summit in New York on Tuesday that the long-term trend for gold should be positive because of strong investment demand and increased jewelry buying. [
]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 within five years and a floor of $500. [
]But slack jewelry buying as prices rise is likely to cap gains, as will a surge in scrap supply, traders said.
Meanwhile, the SPDR Gold Trust's holdings have remained relatively steady in the past 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=> was at $12.61 an ounce, down 2.4 percent from its Monday finish of $12.92.
Spot platinum <XPT=> was at $1,040.00 an ounce, down 1.7 percent from its previous close of $1,058, while spot palladium <XPD=> was at $194.50 an ounce, up 0.3 percent from its late Monday New York quote of $194.
Both platinum group metals have suffered from fears the recession will curb demand from jewelers and carmakers, the major buyers of the metals, which are used in catalytic converters. (Editing by Walter Bagley)
