It's what's safe that's risky!

When "setting bank equity requirements, it is essential to recognise that so-called “risk-weighted” assets can and will be gamed by both banks and regulators. As Per Kurowski, a former executive director of the World Bank, reminds me regularly, crises occur when what was thought to be low risk turns out to be very high risk." Martin Wolf


Wolf ends with:“We cannot hope for miracles. But we can make bankers more useful and less dangerous. Focus on that.”

Indeed, let's all focus on that.

Please free us from imprudent risk aversion and give us some prudent risk-taking

A tweet: "Incentives matter: The escape valves of risk weighted bank capital (equity) requirements, cause banks’ risk models to be more about equity-minimizing/leverage-maximizing, than about analyzing bank assets’ true risks. That’s life!"

Another tweet: "The world has been duped/lulled into a false sense of security by the use of risk weighted assets (RWA) as a real and valid measure of banks' risk exposure. E.g., the duration risk of #SVB long-term government bonds is not included in the weighted risks."

Another tweet: “SVB regulators were ‘asleep at the wheel’” What’s a supervisor to do? Inform his boss Treasury bonds' 0% risk weight must be increased?  It is difficult to get a man to understand something, when his salary depends on his not understanding it” Upton Sinclair

Another tweet: "The most dangerous risk banks take, #unwittingly, is the buildup of huge exposures with assets perceived as safe, those which caused all major bank crisis. Regulators’ risk weighted bank capital/equity requirements, unwittingly, puts that risk on steroids."

Another tweet: "A mixture of thousand solutions, many of them inadequate, may lead to a flexible world that can bend with the storms. A world obsessed with Best Practices [risk weighted bank capital/equity requirements] may calcify its structure and break with any small wind."


Another tweet: "Bank capital/equity requirements mostly based on perceived credit risks, not misperceived risks or unexpected events, e.g., covid, inflation, war, interest rate rise, doom banks to stand naked, when needed the most, when hardest to raise equity"


Another tweet: “A regulation that regulates less, but is more trigger-happy & treats a bank failure as something normal, as it should be, could be a much more effective regulation. The avoidance of a crisis, by any means, might lead us to… the mother of all bank crises”

Another tweet: "Risk weighted bank capital/equity with decreed weights: 0% government – 100% citizens, as if bureaucrats know better what to do with credit than e.g., small businesses and entrepreneurs, is that communism, fascism or just plain vanilla Banana Republic?"

Another tweet: "#SVB have all besserwissers Monday morning quarterbacks explaining us duration risk; why holding long-term government bonds was dangerous. Not a word about why regulators require so little capital/equity/skin-in-the game against these assets.

Another tweet: "The stress test that shall not be dared. What if that what’s perceived as safe is more dangerous to bank systems than what’s perceive risky, and therefore the risk weighted bank capital/equity requirements do not reflect real bank risks?"

Another tweet: "When concocting the risk weighted bank equity requirements, evidently no regulator asked: What would Mark Twain opine about with what assets banks might create dangerously large exposures, with some perceived as risky or with some perceived as safe?
