Honey, I Blew Up the Bank

No, this isn’t a confessional by Jerome Kerviel. Instead, it’s a few excerpts of a very good paper by the Senior Supervisors Group (regulators from France, Germany, Switzerland, Britain and the United States) who went poking around 11 major financial institutions to find out how they botched their risk management so badly last year. The […]

"Fresh credit market turmoil"

It is truly amazing how disconnected credit instruments are from other tradeable financial investments. The Fed released the minutes from its latest Open Market Committee meeting, which lowered the growth forecast and increased the inflation forecast. That shouldn’t be cheery at all; the stagflationary 1970s were a terrible time for equity valuations, but the US […]

Our colleague Susan Webber’s article, “The Dark Side of Optimism” is the cover story in the current issue of The Conference Board Review. It discusses the deep roots of optimism and how it can undermine critical thinking and accurate risk assessment. Her piece is wide-ranging, looking at psychological research, cognitive biases, cultural icons, military history, […]

Credit Default Swap Worries Go Mainstream

Those of us who have an eye for trouble have been nattering about the credit default swaps market from time to time. This $46 trillion unregulated market has suddenly captured the imagination after AIG reported in an 8-K filing that it had certain weaknesses in its internal controls and that the value of its credit […]

Surprise! Wall Street Firms More Prudent as Partnerships

Some have taken notice that investment banks are much more cavalier with other people’s money that they are with their own dough. We’ve gone further in earlier posts, saying that investment banks shouldn’t be public companies (scroll towards the end). A Bloomberg article points out the obvious: the Street has sustained losses unimaginable in the […]

Regulatory Implications of the Failure of Quantitative Risk Management Approaches

A Bloomberg story today points out that the snowballing credit market crisis is an indictment of the use of quantitative measures of risk, particularly one of the longer established and still widely used approaches, value at risk. VAR uses historical trading patterns to determine the probability of loss to a certain percentage of certainty. Firms […]

The Real Failure of Controls at Societe Generale

Disclosure (or apparent disclousues, who knows if we will ever learn the true story) of how equity derivatives trader Jerome Kerviel caused the biggest trading loss in banking history continues to dribble out. Today, Bloomberg in “Societe Generale Says Trader Built Up Positions of EU50 Billion,” gives more detail on how the trader caused so […]

Michael Lewis’ Theory of Why Goldman Got It Right

Michael Lewis, of Liar’s Poker fame, gives an elegant explanation of why Goldman got its subprime position right when everyone else on the Street was disastrously wrong. And I mean elegant in the mathematical sense: it fits known facts and has few moving parts. As Lewis tells it, Goldman did not use the largely impotent […]

The Monoline/Credit Default Swap Nexus (Not for the Fainthearted)

After bond fund giant Pimco’s Bill Gross gave a back-of-the-envelope estimate of a possible $250 billion in losses resulting from the impact of deteriorating corporate credit and bond defaults on the $45 trillion (notional amount) credit default swaps market, other commentators have been making improved (but still quick and dirty) calculations. One interesting effort appears […]

Wolfgang Munchau on the Risks of Credit Default Swaps

Wolfgang Munchau provides nice succinct overview of some of the recent debate surrounding a source of financial system risk that has suddenly captured the popular imagination: credit default swaps. For those new to the concept, credit default swaps are effectively insurance. A protection seller (think insurer) takes the risk of default on a reference entity […]

So How Did Morgan Stanley Lose That $9.4 Billion?

I usually rely on public information, but I’ve had two not-so-public (well, one is public but second-hand) data points converge, and they are consistent with the MSM information on the matter at hand, namely, how Morgan Stanley came to post a $9.4 billion loss on the actions of one trading desk, which in turn led […]

A Riveting Disclosure in the $1 Billion Swiss Re Writedown

These days, a mere $1 billion writedown is such an penny-ante event as to not merit much interest. Indeed, what made the fact that Swiss Reinsurance Co., the world’s biggest reinsurer, lost that much on mortgage related derivatives noteworthy was the fact that it was engaged in that activity at all. It turns out the […]

News Flash: Ben Stein Says Something Intelligent

Before I raise your expectations unduly, I am not saying that Ben Stein’s entire “Everybody’s Business” column today is intelligent. However, this week’s piece, “It’s Time to Act Like Grown-Ups,” had some sensible moments, and I want to give Stein his due on those infrequent occasions when it is merited. I am not parsing the […]
