NEW YORK, Sept 3 (Reuters) - Gold futures rallied to a six-month high near $1,000 an ounce on Thursday as renewed economic uncertainties and inflation fears prompted investors to pile into precious metals as a safe haven.
Gold's sharp rise over the past two days was driven partly by pent-up demand, because longer-term inflation expectations have been rising as central banks keep pumping money into the financial markets to jolt the economy.
"One of the reasons why gold has held steady until recently is that there has been an underlying idea we will have inflation going forward. It doesn't appear imminent, however, so the market had not really been moving particularly on that," said Bill O'Neill, managing partner of New Jersey-based LOGIC Advisors.
Gold and silver stocks outperformed the physical metals, as investors bet on the notion that mining companies would rise further after a lackluster performance due to a sliding stock market. Arca Gold BUGS index <.HUI> jumped over 6 percent.
Strong investment demand fueled gold's gains. SPDR Gold Trust <GLD>, the world's largest gold-backed exchange-traded fund, commonly known as GLD among traders, said its gold bullion holdings rose 1.53 tonnes to 1,063.36 tonnes as of Wednesday -- about 50 tonnes below its all-time high.
U.S. December gold futures <GCZ9> settled up $19.20, or 2 percent, at $997.70 an ounce on the COMEX division of the New York Mercantile Exchange.
The December contract hit a session peak of $999.50, which marked the highest price since Feb. 24, when the equities market had tanked on mounting recession fears.
Spot gold <XAU=> was at $992.15 an ounce at 4:01 p.m. EDT (2001 GMT), against $976.60 an ounce late in New York on Wednesday.
Gold had been rising along with the stock market, but that positive correlation was broken this week when gold rose even as Wall Street tumbled.
"Gold was driven by portfolio diversification out of equities and back into gold as a safe haven as investors are once again reminded of those economic concerns," said David Meger, director of metals trading with Vision Financial Markets in Chicago.
The market was waiting for clues on the economic outlook from Friday's payrolls numbers. Investors were spooked after a U.S. employment report released on Wednesday showed more private sector job losses than expected. [
]Gold should enjoy stronger demand if the data causes the dollar to slip.
SILVER AT ONE-YEAR HIGH
Silver <XAG=> tracked gold higher, hitting its highest level since Aug. 7, 2008 at $16.26 an ounce. The metal, which is usually less liquid and more volatile than gold, was last at $16.11, against $15.34 on Wednesday.
It outpaced base metals such as copper, with which silver, as an industrial as well as an investment metal, often moves.
Gold's solid gains also drove other precious metals higher, platinum <XPT=> was at $1,248.50 an ounce against $1,229, while palladium <XPD=> was at $290 against its previous finish of $284.50. (Reporting by Frank Tang and Jan Harvey; Editing by David Gregorio)
