Platinum prices jumped by 7.0 percent in two weeks to reach 994 dollars per ounce on Thursday. Palladium hit 260.50 dollars per ounce on Friday, the best level since May, 2004.
The gains came as an independent study said that platinum and palladium prices were being supported by increased demand from car and jewellery manufacturers in 2005.
Platinum demand was to have risen by 120,000 ounces to 6.71 million ounces this year, an all-time high, said a report by Johnson Matthey, a precious metals research group and manufacturer.
"Palladium demand will grow by 410,000 ounces to 6.89 million ounces, and with Russian supply expected to fall, the palladium market surplus will be greatly reduced," it added.
Growing demand for platinum autocatalysts used by diesel cars and trucks in Europe, Japan and the United States meant that platinum prices could reach 1,030 dollars per ounce during the next six months, Johnson Matthey predicted.
Palladium was meanwhile forecast to trade as high as 270 dollars per ounce. On the London Platinum and Palladium Market, an ounce of platinum gained to 979 dollars per ounce at the late fixing Friday, from 955.50 dollars the previous week.
Palladium increased to 259.50 dollars per ounce, from 239 dollars.

The new record for copper meanwhile came amid a report that said China stood to lose at least 100 million US dollars on the London Metal Exchange after a bet on copper prices by a state commodities trader went spectacularly wrong.
Citing a source close to China's State Reserve Bureau (SRB), the South China Morning Post reported on Thursday that SRB copper futures trader Liu Qibing took short positions equal to about 130,000 metric tonnes of copper in July and August.
At the time, Liu paid about 3,300 dollars a tonne, expecting the price of copper to decline. Chinese authorities rejected reports of any link to the trader, who has since vanished.

The WTO, acting on a complaint by Brazil, had ruled in March that US cotton subsidies violated international trade rules because they gave US exporters an unfair advantage in the global market.
Britain's request came in London at an event to mark the launch in Britain of "fair trade" cotton products, which guarantee farmers a just price in developing countries, such as African nations like Mali and Togo.
