Central bankers seem to have one purpose over the last few years, and that is to find out anyway possible to stimulate their respective economies. Over the last 20 years, we have seen stimulus in almost all major geographical economic locations and heading into 2017, Central Bankers are running out of strings they can pull.
We see negative interest rates all over the globe, we see interest rates here in the United States advancing only 25 basis points after one of the greatest bull market runs in history. We see Central Banks that are afraid to take tightening measures, and therefore have begun to experiment with new types of quantitative easing.
