With interest rates near 0% and with unprecedented government debt and  deficit spending beyond sustainable levels there is a clear risk of high  inflation or hyperinflation if inflationary (currency cost push) forces are not  counterbalanced with a heavy hand.  In theory, high inflation or  hyperinflation could be prevented by restricting the flow of money and  credit to consumers and businesses.  Such a policy would exert  deflationary pressure on the U.S. dollar within the domestic U.S.  economy since principal and interest payments on existing debt would  drain money from circulation.  While preventing inflation temporarily,  such a policy would not succeed in the long run because, in addition to  offsetting inflation, deflation depresses economic activity and results  in debt defaults.
