LONDON, Feb 1 (Reuters) - Gold and platinum spiked to record highs ahead of U.S. jobs data on Friday as supply concerns and dollar weakness boosted investor sentiment.
Silver surged to a 27-year peak while palladium rose to its highest level in 20 months, tracking strength in gold prices, analysts said.
Spot gold <XAU=> rose as high as $934.70 an ounce and was quoted at $933.35/934.05 at 1128 GMT, against $923.80/924.70 in New York late on Thursday. It jumped 32 percent in 2007 and another 12 percent so far this year.
Platinum <XPT=> set a record high of $1,744 an ounce.
"Power supply concerns continue to buoy prices and is likely to remain a pivotal driver for prices in the medium term," Suki Cooper, metals analyst at Barclays Capital, said, adding the dollar and gold were likely to take cues from the jobs data.
"Our forex strategists note that given the dollar is trading near its lows, the bigger reaction today is likely to come from a downside surprise to payrolls," she said.
The dollar fell to hover near record lows against the euro ahead of the data. The January jobs report, due at 1330 GMT, along with factory activity figures, will offer investors more clues to how close the world's largest economy is to recession.
Some analysts say the U.S. economy is already contracting, and the massive reduction in interest rates over the last four months of over two percentage points clearly shows the Federal Reserve is worried too.
A weaker dollar makes gold cheaper for holders of other currencies and often lifts demand for the metal, which is seen as a hedge against political and financial difficulties.
David Thurtell, analyst at BNP Paribas, said no one was willing to sell in any meaningful size, but there were plenty of buyers in the market.
He said a weak dollar, stronger but shaky equities markets and power problems in South Africa and China, the world's top two gold producers, had lifted market sentiment.

RECORD HIGH PLATINUM
Platinum hit record highs as the protracted power crisis in producer South Africa, which accounts for 80 percent of global output, spurred buying from investors and auto makers.
Platinum <XPT=> jumped as high as $1,744/1,748 an ounce from $1,730/1,735 late in New York on Thursday. The metal surged 37 percent in 2007 and added 14 percent more so far this year.
"We expect acute South African power problems to cost the platinum industry about 200,000 ounces of platinum production in the first quarter of 2008," John Reade, analyst at UBS Investment Bank, said in a note.
"Long-term power issues and other operational factors are expected to swell the platinum deficit to unsustainable levels, unless jewellery demand is displaced by higher platinum prices."
UBS lifted its platinum price forecast to $1,800 an ounce in 2008, $2,100 the next year and $2,300 in 2010 from previous predictions of $1,520, $1,450 and $1,375 respectively.
Silver <XAG=> rose as high as $17.21 an ounce and was last quoted at $17.19/17.24, versus $16.91/16.96 in New York. Palladium <XPD=> rose to $403/406 an ounce from $386/389. (Reporting by Atul Prakash; editing by Michael Roddy)
