You need not to be an Einstein to know that current bank regulations are procyclical.
Jon Cunliffe, Deputy Governor for Financial Stability of the Bank of England spoke on November 15, 2015 about “The outlook for countercyclical macro prudential policy”
He began with: “It is an interesting experiment to think what Einstein might have accomplished had he chosen the world of economics rather than physics. Would he have brought to our world the same brilliant simplicity and achieved the same lasting change in our understanding?”
I have no idea what Einstein would have done in such case but I am absolutely certain about what he would not have done.
He would not have set up pro-cyclical credit risk weighted capital requirements for banks, those which are lower for what is perceived as safe than for what is perceived as risky; those which allow banks to leverage more with what is perceived as safe than what is perceived as risky; those which therefore allow banks to earn higher risk-adjusted returns on what is perceived as safe than on what is perceived as risky; those which therefore in Mark Twain’s supposed words make bankers lend you the umbrella even faster than usual when the sun is out and take it away even faster than usual when it looks like it is going to rain.
When times are rosy and so much can seem safe, then banks need to hold little capital and so when times get bad, and so much seems risky, then banks, on top of their difficulties must also come up with additional capital or shed assets. No Mr Cunliffe Einstein would never have done a stupid thing like that.
Einstein would also have understood that the safer an asset is perceived the larger is its potential to deliver those unexpected losses that bank equity is to serve as a buffer against. To set capital requirements based on the ex ante expected credit losses is as dumb as it gets.
And Einstein would of course, before regulating the banks have asked: “What is the purpose of banks?” And when stress-testing banks, besides looking at what is on their balance sheets, Einstein would also have looked at what is not and perhaps should be.
But come to think of it… you should not have to be an Einstein to get all that!
With respect to developing countercyclical macro prudential policy Cunliffe expresses “I have some sympathy of the ‘don’t do it at all’ approach.
Yes Mr. Cunlifee. The regulators have done more than enough damage as is. Just eliminate the re-clearing in the capital of the perceived credit risk that has already been cleared for with interest rates and the size of the exposure. Don’t you understand that any risk, even though perfectly perceived, leads to the wrong actions if excessively considered?
