The average weighted interest rate on the National Debt will most likely rise in fiscal 2006. For fiscal 2005 (ended Sept 30th), the average interest rate was 4.6%. The rate rose to 4.74% in October.

With continued heavy borrowing, a significant amount of debt due to rollover in early 2006, and rising interest rates, the weighted average rate will probably rise to 5% or more for fiscal 2006.

NOTE: 2006 is estimated at 5%.

The implications for the budget deficit are serious. The National Debt has increased substantially in recent years, while interest rates have been falling. This has kept the debt service payments in the low to mid $300 Billion range.


Now that interest rates are rising, the additional interest payments will add significantly to the General Fund deficit. A small increase to 5% of the weighted average interest rate will add $59 Billion to the fiscal 2006 General Fund deficit compared to fiscal 2005 debt service.

NOTE: Graph shows an estimated fiscal 2006 interest payment of $411 Billion.

Debt service is part of the reason I believe the National Debt will increase by a record $650 Billion in fiscal 2006. The US set an October record debt increase of $94.4 Billion - well on the way to an annual record.
