LONDON, April 29 (Reuters) - Gold stayed firmer on Wednesday but slipped back below $900 an ounce as stock markets rose on both sides of the Atlantic, while trading was cautious ahead of an interest rate announcement from the Federal Reserve later.
The precious metal briefly broke back above $900 after softer than expected U.S. GDP data, which boosted the appeal of assets perceived as a safe store of value. However, it failed to hold those gains as stock markets shrugged off the figures.
Spot gold <XAU=> was bid at $898.05 an ounce at 1508 GMT, against $891.10 an ounce late in New York on Tuesday. Immediately after the data it touched a high of $901.60.
U.S. gold futures for June delivery <GCM9> on the COMEX division of the New York Mercantile Exchange rose $5.10 to $898.70 an ounce.
Traders are now awaiting the Fed's rate announcement at 1815 GMT, after a two-day policy meeting in Washington. "All eyes will be on the Fed," said Citi analyst David Thurtell.
Before the Wall Street open U.S. stock index futures pared gains after data showed gross domestic product fell 6.1 percent, against expectations for a 4.9 percent drop. [
] The anticipation of weaker share prices gave a lift to gold.Other assets perceived as less risky, such as Treasuries, the dollar, also strengthened. While a firmer dollar typically pressures gold, the relationship between the two has weakened recently as both react to risk aversion.
However, gold retreated from highs after stocks brushed aside the numbers to climb at the open amid hopes the Fed announcement will suggest the recession is bottoming out.
Analysts said the bank is likely to keep rates near zero but hold off new measures to flood the economy with money as signs emerge that the deep U.S. economic slowdown may be easing. [
]"Gold buyers are likely to be long ahead of the FOMC meeting this afternoon, rather than short," said Standard Bank analyst Walter de Wet.
"However, given the fall in the gold price yesterday, it does increase the possibility of another sharp move down if the FOMC comes out much more positive than everybody is expecting."
EPIDEMIC
On the wider markets, traders remain cautious over the prospect of a global flu epidemic, which knocked commodities lower early in the week, leading to a dip in gold. [
]Appetite for gold from investors in physically backed exchange-traded funds is still lacklustre after rising sharply early in the year. Holdings of the largest gold-backed ETF remained unchanged for a third session on Tuesday. [
]Meanwhile, Indian gold buyers continued to trickle in ahead of the wedding season, with a dip in prices encouraging purchases. Gold prices in rupees are expected to ease further in the summer but rise by year-end. [
]Silver prices, which had also slipped on Tuesday, rose in line with gold. Spot silver <XAG=> was bid at $12.71 an ounce against $12.45 late on Tuesday.
Among other precious metals, spot platinum <XPT=> was bid at $1,090.50 an ounce against $1,087.50, while spot palladium <XPD=> was bid at $215.50 an ounce against $213.
Both metals, which are chiefly used in autocatalysts, tumbled significantly on Tuesday after General Motors announced restructuring plans, with falling gold prices adding pressure. According to a study of past price movements, the technical outlook for both metals is now negative, Commerzbank analysts said in a note.
However, London-based ETF Securities said it saw a small inflow into its platinum ETF <PHPT.L> on Tuesday. The fund's holdings rose just over 3,500 ounces or 1 percent. (Editing by Anthony Barker)
