Regulators have told Bank of America Corp. and Citigroup Inc. that the banks may need to raise more capital based on early results of the government's so-called stress tests of lenders, according to people familiar with the situation. The capital shortfall amounts to billions of dollars at Bank of America, based in Charlotte, N.C., people familiar with the bank said. Executives at both banks are objecting to the preliminary findings, which emerged from the government's scrutiny of 19 large financial institutions. The two banks are planning to respond with detailed rebuttals, these people said, with Bank of America's appeal expected .. Industry analysts and investors predict that some regional banks, especially those with big portfolios of commercial real-estate loans, likely fared poorly on the stress tests. Analysts consider Regions Financial Corp., Fifth Third Bancorp and Wells Fargo & Co. to be among the leading contenders for more capital. Wells Fargo declined to comment. Representatives of Regions and Fifth Third didn't respond to requests for comment made late in the day. Government officials say their meetings about the stress tests with bank executives over the past few days conveyed preliminary results and that discussions were expected to continue this week about specific findings. They also say that banks directed to raise more capital shouldn't be viewed as insolvent. http://online.wsj.com/article/SB124088901025362487.html
