Bank systems’ “Fifth Risk”: When shit really hits the fan, banks will be holding especially little capital.

Sir, Brooke Masters reviews Michael Lewis’ “The Fifth Risk”, a book that got its titled when John MacWilliams, a former Goldman Sachs investment banker told the author about the “fifth risk”, referring to ‘project management’, the risk society runs when it falls into the habit of responding to long-term risks with short-term solutions.” “Why boring government matters”, November 3.

Well-intentioned bank regulators, wanting to make our bank system safer, and came up with risk weighted capital requirements based on the perceived credit risks. If the perceived credit risks (those that bankers saw and used to adjust to with size of exposure and risk premiums) do not represent the most immediate short-term outlook on risk for banks what does? 

The real long-term risk is obviously that something that was ex ante perceived as safe, and with which banks could therefore build up large exposures, suddenly, ex post turned out very risky. The regulators with their short-term solutions only guaranteed that when shit really hit the fan, banks would stand naked with especially little capital.

Brooke Masters quotes Ronald Reagan with “the nine most terrifying words in the English language are ‘I’m from the government, and I’m here to help’ ”.

Indeed! Just like when regulators told us “we credit rating agencies know all about risks so, with our regulations, we will make your bank systems safer”. As a result they gave us the 2008 crisis, way too much credit for house purchases, and mountains of 0% risk weighted sovereign debt around the world. If only they had stayed home.

Sir, “good boring government” is indeed needed, but beware, few things as dangerous as bored bureaucrats… they’re truly frightening.

Gillian Tett, Anthony Bourdain and Selena Gomez might not explain it all in the “The Big Short”

Sir, I refer to Gillian Tett’s discussion of “The Big Short”, a film based on Michael Lewis’s bestselling book. “Finance gets the Hollywood treatment” November 28.

Tett writes: “We have Anthony Bourdain, the famous chef, standing in a kitchen, describing how a CDO is similar to fish stew (bankers resold old mortgages by mixing them up into fresh broth, just as chefs conceal old fish by turning it into soup). We also see the actress Selena Gomez elaborating the principles of synthetic derivatives while sitting in a casino, placing chips on a table, as groupies mimic her bets.”

I have not seen the film yet but, if Anthony Bourdain did not include mentioning the fact that the quality of the fish stew was to be determined by some very few fish-stew rating agencies; and that the casino in which Selena Gomez placed bets had abandoned the traditional payout scheme in which all bets have exactly the same expected economic value, in favor of one where the safer bets, black or red, pay more than the risky bets, a number, then the film does not fully explain what happened.

Gillian Tett writes “a decade ago [she] was alarmed by the bubble brewing in complex finance…” and indeed in January 2007 she wrote “The unease bubbling in today’s brave new world”

Myself, as an Executive Director of the World Bank, in a formal statement I delivered in October 2004, have also done my fair share of warning writing: “We believe that much of the world’s financial markets are currently being dangerously overstretched through an exaggerated reliance on intrinsically weak financial models that are based on very short series of statistical evidence and very doubtful volatility assumptions”. And in January 2003 in FT I had warned about allowing credit ratings to become a systemic risk.
