Paying off the national debt just got a bit more dangerous, and potentially a lot more expensive.
The interest rates on federal debt began climbing last month, jumping from 1.66 percent on a 10-year U.S. Treasury note at the start of May to a stunning 2.2 percent on Tuesday.
That 54-basis point increase looks small to the casual eye. But if it continues, the higher yield could increase by billions of dollars how much money the federal government spends to service the $16.7 trillion national debt. http://www.thefiscaltimes.com/Articles/2013/06/13/National-Debt-Could-Skyrocket-as-Interest-Rates-Rise.aspx#page1
