Just in case Moody's and S&P didn't frighten you enough, Fitch credit agency has added itself to the list of groups planning to downgrade the United State's triple-A rating if the debt ceiling is not raised by August 2. Per The Hill:
First, the rating would be placed on Credit Watch Negative -- a move already adopted by fellow rater Standard & Poor's. Two days after the deadline, the Treasury has a $90 billion bond due to mature. If the government does not pay in full that bond, Fitch would immediately knock the rating down several notches to B-plus -- the highest possible rating for a nation in default.
