A Decade of Perverse Incentives, Spawned by Basel Risk-Weighting
Let me explain what I mean by "calling it quits." The pillar of Basel II was risk-weighted capital requirements for banks, which allowed them to hold much less capital when lending to credits perceived as absolutely safe than when lending to those seen as risky. The fundamental arbiters of riskiness in this model were the credit rating agencies.
Those perceived risks were already being cleared for banks by means of interest rates, amounts of exposure and other terms. Now banks could expect to earn much higher risk-adjusted returns on equity by lending to the “infallible” sovereigns, the housing sector and the AAAristocracy, than lending to the risky small and midsize businesses, entrepreneurs and startups. From that moment on, when allocating credit, banks would no longer finance the risky future, but restrict themselves to refinancing the safer past.
It took very few years for the banks to consequentially lend much too much to what was ex ante perceived as safe, like Greece, the real estate sector in Spain, or AAA-rated securities backed by U.S. subprime mortgages. All of which brought us the North Atlantic Financial Crisis.
And of course since that fateful day our “risky" prospects, those who we in fact most needed to have fair access to bank credit, have seen less and less of it. Especially when banks were left with too little capital, after so many of those "safe" credits, against which the banks held little capital, actually failed.
When nations stop taking risks, they stall and fall, like a bicycle that does not move forward.
And here we are 10 years later, and the problem of the distortion in bank credit allocation that the risk-weighted capital requirements produce has not even begun to be discussed.
And as a consequence all liquidity injected by central banks, with their quantitative easing, and by governments, with their deficits, turned into a diet based solely on "safe" carbs and fats and no proteins. We now see no muscular growth but only some obese economic expansion.
Like true baby boomers, our current bank regulators have been reacting to their own short-term monsters, without even establishing whether there is any causality between bank exposures to those ex ante perceived as risky and bank crises.
