FDIC, don’t go there! The more similar living wills, stress tests & risk models are, the greater the systemic risks

I just received the FDICs “Supervisory Guidance on Model Risk Management"

It really scares me to read how concerned FDIC still is with how bankers’ develop and use their risk models, among these those for determining capital and reserve adequacy.

I just don’t get it! Let bankers do their job, which is to develop all the models they can that will facilitate their job as bankers, the best they can. And the more crazily diverse these risk models are, the better, as the less is their systemic risk.

FDIC should concern itself exclusively with the what if the bankers of some banks are not good enough when modeling.

And the same goes for living wills and stress tests. Force each bank to present what they think about that, and leave it like that.

In January 2003, while an ED of the World Bank, in a letter published by the Financial Times I argued: “Everyone knows that, sooner or later, the ratings issued by the credit agencies are just a new breed of systemic errors, about to be propagated at modern speeds”

And in April 2003, commenting on the World Bank's Strategic Framework 04-06 I wrote: "A mixture of thousand solutions, many of them inadequate, may lead to a flexible world that can bend with the storms. A world obsessed with Best Practices may calcify its structure and break with any small wind."

I still hold all that to be true… now more than ever!

FDIC, please, they are the bankers and you are the regulator (and insurer), don’t confuse the roles!

FDIC, please, don't insist on being a better banker than the bankers, just be their regulator!
