We do, after all, live in a world in which there are negative interest rates on about a third of global developed market sovereign debt, the 500 euro note is being withdrawn by the ECB, and Ray Dalio, the manager of Bridgewater, the world's largest hedge fund, is now saying helicopter drops of money from central banks direct to people is a growing likelihood.
Politics and economics seem subject to a growing variety of tactics and beliefs, not all of them encouraging.
Paranoia doesn't have to become a trend, but we shouldn't be too surprised it if does.
