Unfortunately no one in the mainstream is too sure what the last chapter was about, and fewer still have any clue as to what the next chapter will bring. There is some agreement however, that the age of ever easing monetary policy in the U.S. will be ending at the same time that the Chinese economy (that had powered the commodity and emerging market booms) will be finally running out of gas. While I believe this theory gets both scenarios wrong (the Fed will not be tightening and China will not be falling off the economic map), there is a growing concern that the new chapter will introduce a new character into the economic drama. As introduced by researchers at Deutsche Bank, meet "Quantitative Tightening," the pesky, problematic, and much less disciplined kid brother of "Quantitative Easing."  Now that QE is ready to move out…QT is prepared to take over.
