> It's very possible that if this is not done, the only banks left at the end of the week will be the "too big to fail" ones

It'll look not very much unlike Canadian domestic banking which has the "big 5" of banks: TD, CIBC, RBC, BMO, Scotiabank.

But instead, with Wells Fargo, Citibank, BOA, etc.

And everything else is really quite tiny in comparison.
