NEW YORK, June 4 (Reuters) - Gold futures rose nearly 2 percent on Thursday, reversing the previous session's sharp decline, as a bullish oil-price forecast by Goldman Sachs ignited a commodities rally and boosted inflation-hedge buying.
Platinum group metals and silver also posted solid gains as a fresh 2009 peak in crude oil prices and the weakening U.S. currency boosted dollar-denominated commodities across the board. The Reuters/Jefferies CRB index <.CRB> jumped 2.6 percent.
"It's predominantly the oil. That's the overall story to this level. It has contributed to the weakness in the dollar and it has provided support on almost every major break" in gold, said Frank McGhee, head precious metals trader with Integrated Brokerage Services.
Earlier in the year, gold prices suffered as deflation fears amid the worst economic crisis since the Great Depression dented bullion's status as an inflation hedge.
However, recent signs of economic recovery, combined with a crude oil rally and renewed worries about excess liquidity from aggressive government stimulus programs, have spurred investment demand in gold.
U.S. August futures <GCQ9> settled up $16.70, or 1.7 percent, at $982.30 an ounce on the COMEX division of the New York Mercantile Exchange.
Spot gold <XAU=> was at $980.20 at 2 p.m. EDT (1800 GMT), against its late Wednesday quote of $962.15 an ounce.
Oil rose above $69 a barrel after U.S. jobs data showed a fall in jobless claims. Rising crude prices help boost interest in commodities as an asset class, and prompted fresh gold buying to hedge against oil-led inflation. [
]Goldman Sachs <GS.N> raised its end-of-2009 oil price forecast to $85 a barrel from $65 and introduced a new end-of-2010 forecast of $95 based on the continued recovery in economic activity, the U.S. bank said in a research note. [
]"As the investing public read that Goldman Sachs is setting $85 a barrel crude oil for 2009, that encouraged people to re-enter the gold market," said George Nickas, commodities broker at FC Stone.
Gold was also boosted by currency moves, as the euro rose against the dollar as ECB President Jean-Claude Trichet signaled the central bank will keep interest rates steady for some time. [
]ETF HOLDINGS DROP
On the investment side, the bullion market largely ignored the news that holdings of the world's largest gold-backed exchange-traded fund, New York's SPDR Gold Trust, posted a small 1.5-tonne fall on Wednesday. [
]Silver <XAG=> was at $15.87 an ounce, up 3.7 percent from its previous finish of $15.30, tracking moves in the gold and precious metals market.
Platinum <XPT=> was at $1,272 an ounce, up 3.1 percent from its late Wednesday quote of $1,233.50, while palladium <XPD=> was at $252 an ounce, up 4.8 percent from its previous finish of $240.50, both benefiting from fund buying. ETF Securities said its silver and palladium ETF holdings both hit record levels on Wednesday. [
