NEW YORK/LONDON, Feb 25 (Reuters) - Gold fell 1 percent on Monday after a U.S. official said that Congress could support gold sales by the International Monetary Fund (IMF), stirring fears that such sales will take a toll on sentiment and weigh heavily on bullion.
"The fact that it has come from a U.S. official carries an obvious weight, but the agreement has to pass through the Congress," said James Steel, metals analyst with HSBC in New York.
The sale of the gold requires U.S. congressional approval and an 85 percent majority vote of the IMF's board of member countries. The U.S. Congress has in the past opposed gold sales to fill IMF's income gap.
"This time may ultimately be no different," said Steel, referring to the ability of the U.S. Congress to strike any plans to sell IMF gold.
Spot metal <XAU=> fell as low as $933.50 an ounce and was at $937.80/938.60 at 2:15 p.m. EST (1915 GMT), against its Friday's late quote of $943.70/944.50 in New York. It hit a record high of $953.60 last week.
The gold contract for April delivery at the COMEX division of the New York Mercantile Exchange <GCJ8> settled down $7.30 to $940.50 an ounce.
David McCormick, U.S. Treasury's undersecretary for international affairs, said in remarks before a speech on IMF reforms that he had some confidence that there would be some support for IMF gold sales in Congress.
"We've done a fair amount of work already in terms of doing outreach to members of Congress," McCormick told an audience in Washington, saying there was already bipartisan support for the move. [
]McCormick added that he hope to build support for action while President George W. Bush is still in office.
The IMF is the world's third-largest gold holder, with more than 3,000 tonnes of bullion reserves.
Steel said gold prices were trading at high levels, and investors should guard against profit taking on bearish news.
PLATINUM SLIPS
Platinum fell after rising towards last week's record high of $2,192 an ounce. The metal <XPT=> was last at $2,135/2,145 after rising as high as $2,163, against New York's $2,148/2,152 late on Friday.
But analysts remained confident that the metal would set new highs after a period of consolidation.
"We continue to believe that platinum will trend higher over the medium term as investors seek safe havens, a hedge against inflation and protection against a weaker dollar," Dan Smith, analyst at Standard Chartered Bank, said in a report.
"However, platinum's fundamentals, and in particular developments in South Africa, are likely to be far more important drivers over the next few months," Smith said.
Platinum might average $2,300 an ounce in the second quarter as underlying structural problems were likely to persist for the time being, he said.
In January, the world's biggest platinum and major gold mines were forced to halt for five days as South African power utility Eskom restricted firms to 90 percent of normal supply, leading metal producers to forecast declines in output.
"Platinum and palladium have been the world's best performing commodities in terms of spot price performance so far this year. This reflects the ongoing power shortages in South Africa," said Michael Lewis, head of commodities research at Deutsche Bank.
Platinum and palladium prices have jumped more than 40 percent this year.
In industry news, South Africa's Gold Fields <GFIJ.J> forecast that gold production for the third quarter would fall between 20 and 25 percent compared with the December quarter due to the electricity crisis in the country. [
]Silver <XAG=> hit a 27-year high of $18.15 an ounce before falling to $18.07/18.12, versus $17.98/18.03 late in New York on Friday. Palladium <XPD=> rose as high as $524 an ounce before falling to $520/525, versus $498/503 an ounce late in New York on Friday. (Editing by Marguerita Choy)
