After General Motors (NYSE:GM) Chairman and CEO Rick Wagoner was forced out by President Barack Obama, Wall Street is betting bank CEO firings will be the next shoe to drop. 

CNBC's New York Stock Exchange floor reporter Bob Pisani told viewers of CNBC's March 30 "Street Signs" the market's actions, with the Dow Jones Industrial Average (DJIA) dropping as much as 300 points, are reflect, in part,that the government is going to force bank CEOs out as they did with Wagoner.

"Look, the main concern here today is Geithner's comments that some banks are going to need a lot more capital," Pisani said. "And for everybody who says why haven't they fired anymore bank CEOs yet - why hasn't the government done it, wait - they're going to."
