Meredith Whitney says banks will have to raise more capital

From CNBC:

U.S. banks will have to raise fresh capital in 2009, and a sharp increase in credit-rating downgrades on mortgage-related securities will lead to further stresses on the companies' capital, according to prominent banking analyst Meredith Whitney.

"From July 2007 to date, over $5 trillion worth of securities have been downgraded, but our concern here is that the pace of downgrades has only accelerated through 2008," the Oppenheimer analyst wrote in a research note dated Jan. 6.
