NEW YORK/LONDON, Aug 11 (Reuters) - Gold erased early gains to trade flat on Wednesday, as investors raised cash to cover heavy losses on Wall Street and as the dollar soared against the euro on sharply lower risk appetite.
An initial rally in gold fizzled as losses in the equity markets deepened, which prompted investors to sell assets across the board. The S&P 500 index <.SPX> dropped 2.5 percent a day after the Federal Reserve downgraded the outlook for the U.S. economy. [
]"There is a time when investors just sell off assets and ask questions later rather than shifting over funds into safe havens," said Tom Pawlicki, precious metals and energy analyst at MF GLOBAL.
"When the stock market liquidates in a very quick fashion, gold doesn't even benefit even though the safe-haven argument is still valid," he said.
Also weighing on gold, the dollar rallied 2.3 percent against the euro and was headed for its best day in nearly two years against a basket of major currencies as a gloomy U.S. outlook and weak Chinese data suggested the world economy was slowing. [
]Spot gold <XAU=> was at $1,199.25 an ounce at 2:47 p.m. EDT (1847 GMT), against $1,201.85 late in New York on Tuesday. U.S. gold futures for December delivery <GCZ0> settled up $1.20 at $1,199.20.
The Fed kept interest rates near zero and said it would use cash from maturing mortgage bonds to buy government debt, keeping an easier monetary policy in place longer than expected.
The Fed's announcement boosted gold initially as the dollar weakened. [
]"The initial reaction was a bit of a knee-jerk for both the dollar and gold, so gold went up and the dollar went off," said Credit Suisse analyst Tom Kendall. "And then this morning, sentiment seemed to reverse."
MF Global's Pawlicki said gold could benefit in the long term as an alternative asset if equity markets stayed weaker. Also, low interest rates generally support gold, cutting the opportunity cost of holding non-interest bearing assets like bullion.
On technical charts, December futures ran into key resistance at their 50-day moving average around $1,215 an ounce. In addition, the contract was trading below support formed by a rising channel line dated back to late July. (Graphic: http://link.reuters.com/ham54n)
OIL, COMMODS DOWN ON DOLLAR RISE
Among other commodities, oil prices fell more than 3 percent, and base metals such as copper also fell sharply on the dollar's strength and worries over economic and demand growth prospects. [
] [ ]Overall, raw materials prices are being pressured by concerns over the Fed's lackluster view on the U.S. economy. This could support gold, however.
"Slower U.S. growth should lead to dollar strength against most risky currencies," Barclays Capital said in a note.
"Such an environment is likely to prove to be favorable for gold prices, particularly given that the recent upside in prices was driven by the resurgence in safe-haven buying," Barclays added
Among other precious metals, silver <XAG=> was at $17.85 an ounce against $18.25, while platinum <XPT=> was at $1,513.50 an ounce against $1,539.50 and palladium <XPD=> was at $463 against $473.75. Prices at 2:59 p.m. EDT (1859 GMT)
