If you are interested to know what interest rates the United States pays on its Treasury bills, you can check them at a site like Bankrate.com.
These rates are down from a month ago. So if anyone tries to tell you rates shot up when S & P flipped out and downgraded US debt earlier this month, make a mental note that that person is not a trustworthy source of financial information.
Rates are also down from one year ago. They are really about as low as they can go, and there’s no movement up yet. Whatever is hurting our economy now, it is not a lack of confidence in the ability of the United States to pay back its debts.
