There are two categories of policy available to the government to influence an economy; monetary and fiscal. Fiscal policy employs government spending and taxation. Monetary policy, primarily overseen by the Federal Reserve and the Treasury is used to control and manipulate the supply and the cost (interest) of money in order to regulate the growth in the economy and the stability of prices. Of the nearly $12 trillion lent, promised and spent so far, Fed Chair Ben Bernanke’s program to drive down mortgage rates is delivering on its promise. Fixed 30-year mortgage rates are now down to 4.78% according to Freddie Mac. They are down for the second week in a row.
