Regulatory reports show 5 biggest banks face huge loss risk WASHINGTON â Five of America's largest banks, most of which have received $145 billion in taxpayer bailout dollars, still face potentially catastrophic losses from exotic investments if economic conditions substantially worsen, their latest financial reports show. Citibank, Bank of America , HSBC Bank USA , Wells Fargo Bank and J.P. Morgan Chase reported that their "current" net loss risks from derivatives â insurance-like bets tied to a loan or other underlying asset â surged to $587 billion as of Dec. 31 . Buried in end-of-the-year regulatory reports that McClatchy has reviewed, the figures reflect a jump of 49 percent in just 90 days. http://news.yahoo.com/s/mcclatchy/20090309/pl_mcclatchy/3184724
