NEW YORK -- Gold futures soared more than 2% in a broad commodities rally Tuesday, as platinum surged 4% after hitting another record high of $2,174 an ounce in electronic trading.

Gold for April delivery rose $20.20 to stand at $926.30 an ounce on the New York Mercantile Exchange. Other metals prices also made big gains.

 
Gold "was assisted by news of fresh write-downs at Swiss bank Credit Suisse, and by a surge in crude oil on the back of growing discord between Venezuela and Exxon Mobil," said Jon Nadler, senior analyst at Kitco Bullion Dealers, in a research note.

 
In Nymex energy trading, crude and other energy futures posted steep gains. Crude for March delivery rose to $97.81 a barrel, up $2.31.

 
Gold also got a boost from weakness in the dollar. The greenback was dogged by worries about the path of the ongoing credit crisis and by ideas that China's central bank might soon raise interest rates to battle surging inflation.

 
The dollar index, which tracks the performance of the greenback against a basket of other major currencies, dropped 0.5% to 75.910.

 
Shares of Credit Suisse Group tumbled after the Swiss bank said, only a week after reporting earnings, that it overvalued asset-backed securities by at least $2.85 billion.
 

Credit Suisse (CS 48.20, -2.68, -5.3%) said it uncovered "errors" in an internal review in connection with "the operation of ongoing control processes." The review was prompted by a KPMG look at its books as the bank was about to go market with a $2 billion bond.
