Bank of America Corp. (BAC), Citigroup Inc. (C) and Wells Fargo & Co. (WFC) were among a number of large U.S. banks that need to raise more capital after the completion of the government's stress tests, according to people familiar with the matter.

The government began informing the 19 banks tested by the government late Tuesday about how much fresh capital they need to withstand the economic downturn. The Federal Reserve is expected to release the full report Thursday after the stock market closes.

It is expected that 10 of the banks that were tested may need capital. JPMorgan Chase & Co. (JPM), American Express Co. (AXP), Goldman Sachs Group Inc. (GS) and Bank of New York Mellon Corp. (BK) won't need to raise more money to shore up their balance sheets, according to people familiar with the matter and reports.

BofA needs nearly $34 billion of capital to survive a worsening recession, according to people familiar with the matter. The Charlotte-based bank received $45 billion in capital from the federal government under the Troubled Asset Relief Program, or TARP.

Citi, one of the hardest hit U.S. banks since the credit crisis peaked last October, will have to raise between $5 billion and $6 billion in extra capital, according to a person familiar with the matter. The move could decrease the government's stake in Citi, which is expected to be about 36% when its preferred shares are converted to common stock. The New York-based bank also received $45 billion in TARP funds.

Wells Fargo needs $15 billion, a person familiar with the matter said. The San Francisco-based bank received $25 billion from the government.

Morgan Stanley (MS) was asked by the Federal Reserve to bolster its capital by $1.5 billion, according to a person familiar with the matter. The firm took $10 billion of TARP money.

Regions Financial Corp. (RFC) is also expected to need more capital, according to a person familiar with the matter. State Street Corp. (STT) is also being asked to raise capital, according to a person familiar with the matter, but an amount was not immediately clear.

Analysts believe other banks that may need capital include Fifth Third Bancorp (FITB), KeyCorp (KEY), PNC Financial Services Group Inc. (PNC) and SunTrust Banks Inc. (STI). Others still left to report include BB&T Corp. (BBT), Capital One Financial Corp. (COF), and US Bancorp (USB).

The tests weren't restricted to traditional banks. GMAC LLC may have to raise as much as $11.5 billion of additional capital, according to news reports. However, MetLife Inc. (MET) isn't expected to need more capital, according to reports.
