TheStreet.com's Jim Cramer says you can game the psychology of the market if you want, but know the rules.

I see the plan: Every day that the market looks like it is going down we give $10 billion to some bank! It is sure-fire. Did you notice the momentary weakness in France Monday? Quick, cut checks to BNP, SocGen and Agricole. Why not? When ING (NYSE: ING) (Cramer's Take) looked like it was a disaster, giving $13 billion to that one-time conservative bank turned all of Europe around!

Monday, when there was a moment that we looked weak, when it looked like we were going to go from plus 200 to below 100, Treasury let it be known that there is a whole other round of checks coming for the second-tier players. Who knows? Boom. That plus higher oil prices turned the market around in the upside-down world we are now in! No doubt soon Downey (NYSE: DSL) (Cramer's Take) and BankUnited (NASDAQ: BKUNA) (Cramer's Take) might get checks and then everything will go higher.

Oh, and on top of that, we have a new stimulus plan, one specially designed, no doubt, to move Target (NYSE: TGT) (Cramer's Take) back to its moving average and get Macy's (NYSE: M) (Cramer's Take) off the critical list.

TheStreet.com's Jim Cramer says the government needs to step in and take charge, and it needs to do it now.

We all know it. All of us. We know that the subprime mortgages that Lehman (NYSE: LEH) (Cramer's Take) wrote in Europe have come back to haunt them. We know that AIG (NYSE: AIG) (Cramer's Take) insured a lot of bad paper over in Europe when it decided to "avoid" the U.S. Subprime financial insurance, if you can call its multi-billion-dollar exposure "avoidance."

We know that Washington Mutual (NYSE: WM) (Cramer's Take) can't absorb the losses itself.

We know that Downey (NYSE: DSL) (Cramer's Take) and Corus (NASDAQ: CORS) (Cramer's Take) and BankUnited (NASDAQ: BKUNA) (Cramer's Take) can't raise the money they need.

We know all of these things. I think the federal government does, too. We lived in an unregulated time where everyone acted badly and no one protected anyone, and now these institutions have to be dealt with in a way that is the least painful of all the painful ways.

Of course, though, this government has no desire to deal with things until guys like Bill Gross or the Chinese government say, "We are done buying your paper," when it came to Fannie Mae (NYSE: FNM) (Cramer's Take). I guess they want a run at the bank of Washington Mutual and they want customers to stop doing business with Lehman before that's sold for scrap, although I must say that the Bear deal worked pretty well for everybody except Bear shareholders.

TheStreet.com's Jim Cramer says this bank on the FDIC's problem list is big enough to matter.

How much was made of the FDIC's "problem bank" list yesterday? Frankly, a little too much -- the list could be 200 banks long and be insignificant or it could be five banks long and be of incredible importance.

Is there any doubt that that the FDIC can handle 100 banks of the $1 billion to $2 billion variety? There shouldn't be. They can look the other way on most of them if they have to, or close them sequentially while asking for more capital along the way.

But if BankUnited (NASDAQ: BKUNA) (Cramer's Take) with $7 billion in deposits goes under, that'd makes headlines. It would be particularly newsworthy because it is in a visible location (the Miami area) and would cause a flood of stories about older people worried about their deposits -- pensioners -- and a big round of stories about how horrible Florida real estate really is. Then you get stories about how IndyMac and BankUnited represent the "system," and when you add that to the woes of Fannie (NYSE: FNM) (Cramer's Take) and Freddie (NYSE: FRE) (Cramer's Take) -- which are now directly making it harder to get cheap mortgage money because they are paying through the nose for their own money and buying fewer mortgages, just want we don't need -- and you get headlines galore about how bad things are. When you couple that with the inaction of Treasury on the FNM/FRE front, you are going to be in for a test of the July 15 lows.

Last week, the FDIC oversaw the second biggest bank failure in U.S. history -- $32 billion IndyMac Bancorp (NYSE: IMB). I thought more would be on the way and this morning's New York Times estimates that 150 of the 7,500 U.S. banks will fail in the next 12 to 18 months. The FDIC only has $53 billion in its fund to cover bank failures so it is going to be needing much more cash, which it may get from raising insurance rates. No doubt those of us with bank accounts will pay the price.

For those looking to profit from this failure, it's time to get a hold of the FDIC's problem bank list and start estimating the ones that are most likely to get taken over. Here are some hints: look at their mortgages as a percent of total loans, their cash flow, when they have to pay back their debt, and the increase in the rate of their bad loans. The Times mentions two that are probably already on the radar of short sellers:

• BankUnited Financial Corporation (NASDAQ: BKUNA) in Florida, which trades at 77 cents a share and is probably too far gone to profit from as a short, went for $20 a share a year ago.
• Downey Financial Corporation (NYSE: DSL) in California, which trades at $1.69 today, traded at $65 a year ago.
