Why so much noise about USA's credit rating being lowered?
The credit scale is deceptive, it goes: AAA, AA, A, BBB, BBB-, BB+, BB, B, CCC, CC, C, D. In reality it should be A,B,C,D,E, F, G,H, I, etc. The current scale does not reflect with clarity the ranking of risks and ratings. AA is much worse than AAA, but the uncertainty involved can be scary. Check out these corporate and sovereign debt credit ratings.
