    A couple of years ago - or before banks started to go bust - economists sometimes liked to talk about a phenomenon they christened The Great Moderation.

On Friday, the Chicago Board Options Exchange Volatility Index, the Vix, rocketed 32.1 per cent to 89.53, as equity markets suffered another dramatic sell-off.
