Certainly, the Fed will not tighten fiscal policy. The Fed will either keep fiscal policy the same or the Fed may also loosen by announcing additional asset purchases such as Treasuries or MBS. However, the Fed is already purchasing more Treasuries than it is claiming which is seen by a jump in M2 since August 2011. The Fed must continue to hold bond yields down in order to keep US borrowing costs low as well as to keep mortgage rates low and support the struggling housing market that has already past the 50% mark of mortgage holders being underwater and is on the verge of a rapid decent in housing prices which would collapse the banks. If rates rise even a few percent to traditional levels, the US will default and the USD will be significantly devalued or may even become worthless.
