There is a truly excellent piece by John Lanchester about the City of
London in today's London Review of Books. It's the best writing about the City I've come across since reading Liar's Poker and Freud in the City.
Lanchester includes a personal reflection on the impact of the City's wealth on
the rest of London, provides the best explanation of derivatives I've
ever come across and gives an exemplary history of the post Big Bang era
covering Leeson, LTCM, Enron, hedge funds and the recent debacle at Northern Rock.
While we watch as the impact of the CDO debt losses trickle through to the rest of the economy in 2008 we could worse than to reflect on how bad it could really get if we don't keep a closer eye on what the traders are up to: "In 2003 the total size of the world economy was $49,000,000,000,000.
The total size of the derivatives being traded was $85,000,000,000,000.
In other words, derivatives today are worth far, far more than the
total economic activity of the planet. More than $1,000,000,000,000 of
derivatives are bought and sold every day."
