LONDON, Feb 5 (Reuters) - Platinum hit a record high above $1,800 on Tuesday on supply concerns, but later lost steam as a dollar rise triggered profit-taking and dragged down prices as much as 1.7 percent.
Palladium also fell in choppy trade after rising to its highest in six years, gold slipped to a two-week low after setting historic highs last week and silver fell more than 1 percent.
"As platinum moved above $1,800 an ounce, some people started taking profits. The market was a little bit overbought today and you just see a consolidation at the moment," Michael Widmer, metals analyst at Lehman Brothers, said.
"But fundamentals are still very strong. We are going to have a deficit on the platinum market this year, with shortfalls of around 200,000 ounces by the end of the year.
"I wouldn't be too concerned about the price fall today and still think that $2,000 is a realistic target."
Spot platinum <XPT=> hit a high of $1,809 an ounce before falling to $1,760/1,765, down from $1,790/1,800 late in New York on Monday.
Analysts said a rise in the dollar also made the upward move in precious metals prices difficult.
The euro fell sharply against the dollar as surprisingly weak euro zone service sector data increased pressure on the European Central Bank to cut interest rates to shore up growth.
A firmer dollar makes precious metals costlier for holders of other currencies and often lowers demand.
Analysts said the worst was far from over for South African mines, which produce four-fifths of the world's platinum, after state power firm Eskom allowed them only limited increases in their electricity consumption.
"Ongoing power problems in South Africa indicate further production problems in this already tight market," Fairfax said in a daily metals note.
"Platinum producers had hoped to be largely back to work this week but may remain subject to power restrictions for some time," it said.
Platinum and palladium are used in jewellery and in vehicle catalysts, where they help clean exhaust gases.
GOLD STRUGGLES
Gold remained under pressure after Friday's rally to a record high of $936.50 an ounce induced profit taking, but some dealers said the metal was still on track to touch new highs due to uncertainties in the dollar's outlook.
Spot gold <XAU=> fell as low as $887.60 and was last quoted at $892.10/893.00, against $904.40/905.10 in New York.
"I am not surprised by the profit taking. Overall we are going to have rising prices as the upward move in gold is not over yet," said Widmer of Lehman Brothers.
Gold has gone up by as much as 12 percent this year, and physical dealers expect buying on dips from jewellers to persist, though trading has begun to slow down in Asia ahead of this week's Lunar New Year celebration.
London-based consultancy GFMS said on Monday that the price of gold is likely to peak at just over $1,000 per ounce in 2008 and benefit from any weakening of the U.S. economy as investors seek new havens for their funds, [
]Silver <XAG=> fell to $16.55/16.60 from $16.69/16.74 an ounce, while palladium jumped as high as $426.50 before slipping to $411/415, versus $423/428 late in the U.S. market. (Additional reporting by Lewa Pardomuan in Singapore) (Reporting by Atul Prakash; editing by Michael Roddy)
