Evidence that demonstrates, without any reasonable doubt, we have landed us some very feeble-minded bank regulators

What are the chances banks build up huge exposures to those rated prime, AAA to AA, and which could be dangerous to the bank system, if these, ex post, turn out to have been worthy of a much lower rating? Big!

What are the chances banks build up dangerously large exposures to those rated “highly speculative “ and worse below BB-? None! 

And yet the regulators, for the purposes of determining the capital requirements for banks, in Basel II, assigned to the AAA to AA rated, a risk weight of 20%, and to the below BB- rated, a risk weight of 150%.

And to top it up, the risk weights are portfolio invariant.

Do we really need more evidence that the Basel Committee regulators and those affiliated to it are cuckoo?

They behave like nannies telling the children “Stay away from the ugly and foul smelling, and embrace the nice gents bringing you candy”, and so dangerously distort the allocation of bank credit to the real economy.

Voltaire to the Basel Committee: “May God defend me from my friends [AAA rated]: I can defend myself from my enemies [BB- rated]”

Here is a brief memo that further explains their idiocy.
