Bank capital requirements or bank leverage allowances?
Martin Wolf referring to Windows of Opportunity by David Sainsbury writes that growth is “exploiting new opportunities that generate enduring advantages in high-productivity sectors and so high wages… developing something fundamentally new is often costly and risky” “Why once successful countries get left behind” February 22.
Indeed, but as Pope John Paul II, in his Apostolic Letter "Novo Millennio Ineunte" reminded us of the words of Jesus when one day, he invited the Apostles to "put out into the deep" for a catch: "Duc in altum" [and] "When they had done this, they caught a great number of fish".
Sir, “risk weighted bank capital requirements” reads like a very sophisticated tool that, when it comes to keeping our bank systems safe, is expected to assure great prudence. For instance, a 20% risk weight assigned to AAA rated asset and 100% to loans to unrated entrepreneurs and using Basel Committee’s basic 8% capital requirement, translates into 1.6% in capital for AAA rated assets and 8% for loans to unrated entrepreneurs. At first sight, that seems quite reasonable, because of course AAA rated could be five times riskier than what’s not rated.
But there is another side of that coin, that of a very costly risk-taking avoidance. It becomes much clearer if we label the former as “risk weighted bank leverage allowances”.
Doing so we observe banks are allowed to leverage 62.5 times to one with assets rated AAA, but only 12.5 times with loans to unrated entrepreneurs. The question then is: if banks are allowed to leverage 50 times more their capital with AAA rated assets, why would any bank lend to unrated entrepreneurs, that is unless these pay much more in interest rates would in order to make up for that regulatory discrimination?
Sir, John A. Shedd wrote “A ship in harbor is safe, but that is not what ships are for” and I am sure FT agrees that applies to banks too. Unfortunately, current regulations have banks dangerously overpopulating “safe” harbors, e.g. residential mortgages, while leaving those deep waters that need to be explored in order for once successful countries not ending up left behind.
