NEW YORK/LONDON, Aug 25 (Reuters) - Gold futures ended higher on Tuesday as the dollar dipped, but slipping crude oil prices prompted gold to give back early gains ahead of upcoming COMEX option expirations.
For the second straight day, gold erased sharp gains as the dollar retraced losses and equities markets slipped off session highs.
George Gero, vice president of RBC Capital Markets Global Futures, said bullion traders were anxious ahead of a possible volatile day on Wednesday due to the expirations of COMEX gold, silver and copper September options and the weekly U.S. crude inventory report.
"That is why gold gave up gains from this morning. The market sold off because people pared back their positions for tomorrow, and the euro/dollar is also off its early exuberance," Gero said.
U.S. December gold futures <GCZ9> surged to a session high of $954 but then settled up just $2.30 at $946 an ounce on the COMEX division of the New York Mercantile Exchange.
Spot gold <XAU=> traded at $943.70 an ounce at 3 p.m. EDT (1900 GMT), up from $941.40 an ounce late in New York on Monday.
The dollar dipped against a basket of six major currencies after data showed prices of U.S. single-family homes rose for a second straight month in June and consumer confidence rose more than expected in August.
The dollar was also knocked by a recovery in equity markets, as Ben Bernanke's reappointment as Federal Reserve chairman was seen as likely to encourage investors to take on riskier trades. [
]A weaker dollar often lifts gold, which can be bought as an alternative to the unit.
Wall Street stocks rose after the U.S. data, with the S&P 500 <.SPX> hitting a 10-month intraday high in the morning. The stock market also retreated from early gains.
JEWELERS ON SIDELINES
Demand for gold was soft, with jewelers in India, the world's largest bullion buyer, keeping to the sidelines in anticipation of further price falls.
Among other precious metals, palladium prices rose to their highest level in nearly a year as hopes for an improvement in the balance of supply and demand and gains in gold boosted interest in the autocatalyst material.
"People are looking at ways to leverage off the expected turnaround in the auto industry," said Mitsubishi Corp precious metals strategist Tom Kendall. "As sales pick up, they are looking for palladium to be the chief beneficiary, as opposed to platinum, with the substitution story continuing."
Spot palladium <XPD=> was at $285.50 an ounce against $279.50, having earlier touched a high of $287.50, its highest price since early September last year.
The world's No. 2 platinum producer, Impala Platinum, said a strike had halted its largest operations in South Africa, and it was unclear how long the industrial action would last. [
]South Africa produces four-fifths of the world's platinum.
Platinum <XPT=> rose to $1,240.50 from $1,236.50 an ounce, while silver <XAG=> was at $14.27 an ounce against its previous finish of $14.13. (Reporting by Frank Tang and Jan Harvey; Editing by David Gregorio)
