Another day, another loser bank....

PARIS — Credit Suisse, the Swiss banking giant, said Thursday that it expected to post its first quarterly loss since 2003 because of large write-downs and losses related to “intentional misconduct” at its trading desk.

In a statement, the Swiss bank said that it would write off $2.65 billion for the fourth quarter of 2007 and the first three months of 2008. Credit Suisse also restated its fourth-quarter net income lower to 540 million francs from the original estimate of 789 million francs, or $788 million. Profit for 2007 declined to 7.76 billion francs.

The anticipated loss at Credit Suisse, on the heels of its write-downs and its trading irregularities in light of the rogue trading case at Société Générale, added to questions about how banks worldwide were managing risk during the expanding credit crisis that stemmed from problems in the mortgage markets in the United States.
