BHG> Thanks for the link. I did find the reading enjoyable.
Except it doesn't prove much. I searched for "full faith" and it only came up as text of "signs" that would be "prominently displayed". Also, the text was either:
1) The other will indicate deposits are insured by the Federal Deposit Insurance Corporation and/or "Deposits Federally Insured to $100,000--Backed by the Full Faith and Credit of the United States Government."
or
2) "Deposits Federally Insured to $100,000--Backed by the Full Faith and Credit of the United States Government."
Notice that FDIC is supposed to be contacted only if 1) is applicable, but OTC (Office of Thrift Supervision) is the ONLY listed option when 2) applies. Thus, nice "red herring", BHG. Thus, the link you provided did little to help your argument and did not establish at all that FDIC-insured accounts are backed by "full faith" and "credit" of USG.
Another red herring, which, nonetheless, may be used as circumstantial evidence, is your reference to FSLIC. Still, circumstantial evidence of the government's behavior, as evidenced by very recent events, shouldn't be taken for granted. Remember how the government decided to save Bear Stearns by a forced sale, but let another big ivestment bank fail and go into bankruptcy?
Yes, I'm actually an economist. However, that was a nice ad hominem attack from you
Whenever my opponents choose to go after me personally rather than discuss my reasoning, I know they must not have good arguments to support a differing position or do not have the skills necessary to construct such arguments 
The magnitude of the current crisis is quite profound. Many events that most would think only a year ago were impossible came to be a fact. Thus, I wouldn't trust past performance too much in making decisions about the future.
In the current environment, I think it's prudent to diversify holdings among different banks. Further, with the deposit rates being nothing to write home about currently, I'd probably pull at least some money out of WAMU and stick them into say ING. The difference would be 1-1.5 percentage points in the interest rate, but it's much easier to imagine a scenario when both your ONE bank and the FDIC fail than all of your SEVERAL banks and FDIC all fail 
I did have a very pleasant experience with the Netbank failure, as the account got converted to ING and access to the money was not interrupted for more than a couple of days. Still, it doesn't guarantee that the same would continue to apply as losses mount.
beethovengirl said:Economist said:Thus, it may come a time where FDIC runs out of funds to pay the claims of the insured depositors. Absent a government bailout (which now seems very likely but not guaranteed)
Actually, a government "bailout" is guaranteed, as the FDIC is backed by the full faith and credit of the US Government. In fact, during the savings & loan crisis, the FSLIC became insolvent, and it's not hard to guess how it got recapitalized.
Are you actually an economist?
