If financial market volatility was given up for dead in 2017, then get ready for a resurrection. To understand why, take a look at the incoming economic data. When the underlying dynamics of the economy change, the data tend to become more volatile before markets react.
Economic volatility as expressed by the standard deviation of changes in the monthly data has been on the rise since the summer as the global economy gained strength. Financial market volatility, though, has fallen amid a lack a surprises in central bank policies, receding geopolitical tensions and upbeat corporate earnings. But as history shows, such divergences between economic and financial market volatility only last for brief periods. As such, a rebound in market volatility has the potential to be a key driver of risk premiums, bond yields and valuations in 2018.
