Over the past century central banks have become the guardians of our economic and financial security. The Bundesbank and Federal Reserve are respected for achieving monetary stability, often in the face of political opposition. But central bankers can also lose the plot, usually by following the economic dogma of the day. When they do, their mistakes can be catastrophic.
Today the behaviour of the European Central Bank suggests that it too has gone awry. After seven years of ever-looser monetary policy there is increasing evidence that following the current dogma, broad-based quantitative easing and negative interest rates, risks the long-term stability of the eurozone.
