You're basically regurgitating the noise pushed by these banks and their central banking colleagues/friends at the Federal Reserve that they are to big and to important to be allowed to fail. That we could not possibly deal with the fallout or live without them. That is just nonsense and frankly those who would of taken the largest hit would of been those with the biggest interest in these bank which FDIC insurance does not cover. However as it stands now it was the tax payer/little guy who has been royally screwed over and lied to by everyone in this mess which includes these banks, the Federal Reserve and the Federal government itself.
Edit: If you want to see what happens if banks are allowed to fail then take a look at Iceland. While they did everything possible to save their banks and briefly jumped in to take over their own national banks (currently these 2 of these 3 banks are owned by the creditors) in the end they allowed failure to occur while protecting and managing the crisis for little guy in manner which has benefited their nation and yes they were very much able to deal with the "complexity" of these banks holdings and assists.
This is what a completely uneducated person regurgitates.
Do you know what an Asset Backed Commercial Paper conduit is? Do you know what a "normal" one finances (not a SIV or SecArb)? Let's say one is ~$10bn, it may have ~70-80 separate lending facilities. Those facilities may finance another few tens of thousands of borrowers from fleet leases to retail auto loans to dealer floorplan loans or small business equipment leases (copiers, computers...etc). Each ABCP conduit is backed by two facilities, a liquidity and letter of credit, both usually issued by a bank to "backstop" the conduit if a deal inside of it goes bad or if the CP market isn't around to finance the conduit (it happened, hence CPFF).
Now, pray tell, what the fuck do you think happens if the bank, which backstops the conduit, suddenly goes away? Do you think those tens, if not hundreds, of thousands of initial or tertiary borrowers just say "Well, I'll take this over to this smaller regional bank!". No, it takes MONTHS to structure an conduit deal, it takes MONTHS to market that ABCP to investors, it takes millions of dollars to set up the ABCP conduit and then the deals themselves.
This is only the topsoil of a huge banking effort that finances larger companies which finance individual obligors.
What about trade finance? Trade receivables, 30-day net 10 plain-old AR, are sometimes financed through ABCP, sometimes through trade AR deals on bank balance sheets. What happens if those facilities just "go away"? Do you think that it is easy for XYZ small/medium business to just go get another deal within days in order to finance their own customers?
If you are making widgets and you finance your own customers for 30 day net 10, what do you tell them? Do you think it's all cool that you got fucked because some dipshit online thinks the whole system should go to hell?
And then what do you do with your workers? Once your own cash runs out, because you need to finance your customers or they go somewhere else, where do you get a temporary liquidity facility to make payroll? Because, naturally, if you take one bank down several more will go and they will all roll back lending to preserve liquidity.
This is what utterly baffles me about people who know ABSOLUTELY NOTHING about banking. You don't even try, you just want to say "ME GRIMLOCK, SMASH SMASH SMASH!"
Get a clue, fool.
And as far as saying that I just want to keep the status quo, fucking read. I want to break the banks up so that none are big enough to matter that much if they fall, that it will be easier to delink the risk that a small business will be able to move easier/faster/better. I am for TBTF until there is nothing left that is TB.
And as far as the comparison to Iceland - a big ABCP facility can be as big as Iceland's annual GDP. Comparing the two only highlights how simple minded you are.
