The Fed is an a very tight spot now. It has pretty much announced that it will do another round of QE (although they claim that they don't want to devalue the USD!). Some expect it to be over $1T. Goldman Sachs says it will be $2T.
If they do it, the US Dollar will collapse. If they don;t, the markers will collapse.
The Fed will decide this in early November.
