How to Think About Standard and Poor's Downgrade

by Dean Baker

Standard and Poor's downgrade of U.S. government debt captured headlines across the country and around the world. It is a newsworthy event, but primarily as another colossal failure by a major credit rating agency.

First, it is worth mentioning the important background here. S&P, along with the other credit rating agencies, rated hundreds of billions of dollars of subprime mortgage backed securities as investment grade. They were paid tens of millions of dollar by the investment banks for these ratings. We know that concerns were raised by their own people about the quality of many of these issues. This was at the least astoundingly incompetent. It was quite possibly criminal.

This raises the question of whether S&P fears an investigation and possible prosecution. In such circumstances the desire to curry favor with powerful politicians could certainly influence their credit rating decisions. There are also rules affecting the credit rating agencies in the Dodd-Frank financial reform bill. The desire to have these rules written in a favorable way could affect the credit rating agencies' decisions. It would be nice if we could just assume that the credit rating agencies make their rulings on an objective assessment of the evidence, but we can't.
