Excess volatility & how central banks respond to it
We use excess volatility as the hurdle rate by which equities must beat bonds, in order to be risk-efficient. In the US, it has just hit a new low going back to 1995. In the Eurozone, it is at a new 20-year low. Risk conditions have never been more benign. This means that they are very likely to deteriorate, possibly quite soon. We also think that central banks want this to happen – but not too much.
