Follow the link and look at the chart.
Here’s a chart from the report that’s worth a look. It shows the economic interactions among three sectors: government, households/firms, and finance. Each pairwise interaction is a self-aggravating cycle, and central banks are being asked to intervene at all three points. I remember when monetary policy used to be one target (prices), one instrument (interest rates). Happy days.
That’s three autocatalytic potentially out-of-control loops, each draining the central banks.
