Bank Losses From Swiss Currency Surprise Seen Mounting

``Citigroup, the world's biggest currencies dealer, lost more than $150 million at its trading desks, a person with knowledge of the matter said last week. Deutsche Bank lost $150 million and Barclays less than $100 million, people familiar with the events said, after the Swiss National Bank scrapped a three-year-old policy of capping its currency against the euro and the franc soared as much as 41 percent that day versus the euro. Spokesmen for the three banks declined to comment.''
