Problems maybe with the US dollar and possible inflation??
Excerpt from Sprott Asset managment:
The US government raised $705 billion worth of new debt in 2008. The debt was raised to pay for a $455 billion budget deficit and $250 billion in “supplemental appropriations” for the wars in Iraq and Afghanistan.
In 2009, the US government will (and must) sell $2.041 trillion in new debt. This debt will pay for a projected budget deficit of $1.845 trillion, supplemental appropriations of $196 billion for Iraq and Afghanistan, a fund for pandemic flu response and a line of credit to the IMF.
In fiscal 2009, the United States must find buyers for almost three times the debt that was issued last year.
