Casey points to the co-dependency between stock market investors in the U.S. and the Bernanke Federal Reserve. The stock market slumped in July 2013 and then hit new highs when Fed chairman Bernanke clarified that monetary policy will contiue to be accomodative for a long period with rates low even as the Fed tapers off its bond purchases. This makes the task of normalizing interest rates tricky for the Fed. Bernanke and the rest of the Open Market Committee have to consider the problems of a bubble in the stock markets, avoiding a destabilizing selloff in markets because of strong signals of normalization of rates, and changes in economic conditions in the U.S. and to some exent globally. Similiar reassuring statements were made by the head of the Bank of Japan, Bank of England and the ECB.
