In US FDIC, which insures bank accounts upto USD 250K, has basically obfuscated Good Bank vs Bad Bank quality check for the retail customer.

The Fed Reserve and Treasury and FinGov apparatus does some 'stress tests' but mostly a dog and pony show.

Banking in US is mostly element of convenience than quality. No one ran from Wells Fargo accounts (at least retail users) to say Bank Of America because Wells Fargo is fined for basically fraud.

In short term its a good thing, in long term.. well it is prone to blow up, I hope that is not in my life time.
