TheStreet.com's Jim Cramer says struggling banks can be shorted to oblivion now that the rules won't be enforced.

Memo to the FDIC: Watch your back. The SEC just flipped its allegiance to the bad guys, the guys who want to break not just certain banks, but your bank! That's right, with the scrapping of the emergency rule that eliminated naked shorting, where you don't have to find the stock, and with the end of the vigilance against bear raiding, the SEC may have just caused a run at the FDIC.

I had hoped that the SEC would see that these financials have been manipulated to unreasonable levels, making the confidence in all institutions so low that nobody wanted to give them money. The rule change -- which when you think of it, wasn't much of a rule change as much as an enforcement of the way things are supposed to be, where you actually have to find the stock you sold short first so you don't fail to deliver -- worked!

It gave the system some breathing room. I think the rule change might have saved Merrill Lynch (NYSE: MER) (Cramer's Take) from being shorted into oblivion so it couldn't have done its deal. Lehman (NYSE: LEH) (Cramer's Take) didn't do a deal, those bad boys be back on the griddle now for unknown European exposure. AIG (NYSE: AIG) (Cramer's Take) wasn't protected in the first place and I believe will need to raise $10 billion to $15 billion in the teens to cover its European exposure. Now there's little hope at all for Fannie (NYSE: FNM) (Cramer's Take) or Freddie (NYSE: FRE) (Cramer's Take), as their stocks will be blitzed into oblivion and Hank Paulson will have to start the planning of cash infusions as opposed to what he said last Sunday -- why did he say that, for heaven's sake? Maybe he's too close to John "We don't need capital" Thain from their Goldman (NYSE: GS) (Cramer's Take) days.
