What’s wrong with deregulating lousy regulations? Get rid of risk-weighted capital requirements for banks… but gently

Sir, Patrick Jenkins speculates on what Trump will do to bank regulations and regulators and how the latter would respond in America and in Europe. “Trump’s agenda on deregulation is as vital as his Nato policy” November 15.

I just know that with statist and distorting regulations, like the current risk weighted capital requirements, deregulation and getting rid of regulators, would be a good thing. But of course, that needs to be done with utter care, since you could otherwise easily make the cure worse than the disease.

The basic principle with respect to any changes in the capital requirements should be grandfathering, so that these only operate on the margin of the new, without shaking up the average of the old. Of course grandfathering should not be a tradable feature. If a European bank carries a low capital requirements mortgage on its book, and holds it that way until it runs out that is ok, but it should not be able to profit by selling low capital requirement’s mortgages to other more "needy" banks.
