The implications of the U.S. Federal Reserve's loose monetary policy. Total U.S. debt in 2012 is expected to be $11.58 trillion, with 52% of this in maturities of less than 3 years. The average interest on this is about 2.24% in January 2012, with interest on the debt at about 225 billion in Jan. 2012. If interest rates were to go up in 2014-2017 as forecast by the CBO, an interest rate of 5-6% would result in doubling or tripling the amount of interest on U.S. debt. The U.S. Treasury is financing the huge increase in debt- $5 trillion added in the last four years- through low interest rates and shorter maturities. This stores up large financial risks for the future including calls for tax increases to pay for a sudden rise in the interest on U.S. debt.
