Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Apparently the remarkable events of 2008 were so unlikely some bankers were labelling them as '25 sigma' events.

See e.g. here.

So very, very unlikely, it's astounding they happened at all.

What is even less likely, but shockingly true, is that similar events happened every time we allowed the Finance Sector to operate in such an unregulated manner and that as the US rolled back regulations aggressively beginning in the 1970's, it experienced a series of crises.

A 25 sigma event that is a repeatable economic experiment and  has warning tremors! That's so unlikely I reckon it surely must quality for an extra sigma.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
