…I think the whole thing is preposterous. S&P downgrading the United States is like Consumer Reports downgrading Coca-Cola. Consumer Reports is a great institution. For example, if you want to know how reliable a 2007 Ford Explorer is going to be, they have done more research than anyone to figure out the reliability history of every single vehicle. Those ratings are a real public service, since they add information to the world. But when it comes to Coke and Pepsi, everyone has an opinion already, and no one cares which one, according to Consumer Reports, “really” tastes better. When S&P rated some tranche of a CDO AAA back in 2006, it meant that some poor analyst had run some model fed to her by an investment bank and made sure that the rows and columns added up correctly, and the default probability percentage at the end was below some threshold. It might have been crappy information, but it was new information. When S&P rates long-term Treasuries AA , it means … nothing.
