Emeritus a University of Chicago finance professor John Cochrane has been screaming for years that the whole design of more and more regulations combined with all sorts of implicit ex-post creditor insurance is structurally unstable and all but guarantees bank runs and collapses every decade or so. That the only thing that can work is much higher capital (not reserve!) requirements, i.e., a lot higher shareholder equity vs debt on the balance sheet. He mentions that existing bank regulations already number hundreds of thousands of pages, yet the regulators apparently got blindsided by duration/convexity risk which is CFA / MBA finance textbook material. Just like generals, regulators are always fighting the previous crisis.
