Late Friday, the United States was booted out of a prestigious group of countries that boast a spotless credit rating.
Now only 15 countries (and the very small Isle of Man) hold the triple-A rating from both Standard & Poor's and Moody's...
The United States for example, has seen its dollar become the world's No. 1 reserve currency because its bonds are held in such high regard by investors. They're backed by the "full faith and credit of the U.S. government" -- which until now, has never seriously been called into question.
On Friday, S&P downgraded the United States to AA+, an investment grade level just one notch below triple-A. It marked the first time the world's largest economy has been downgraded, since Moody's first gave the country a credit rating in 1917.
S&P cited estimates that U.S. government debt would balloon to 79% of the size of the entire U.S. economy by 2015, and 85% by 2021 -- a level S&P says is consistent with AA+ rated countries.
