| An Examination of Rating Agencies' Actions Around the Investment-Grade Boundary by Richard Johnson of the Federal Reserve Bank of Kansas City February 2003 Abstract: Data on credit ratings by the agencies with the legal status of Nationally-Recognized Statistical Rating Organizations (NRSROs) show some tendency for one-day downgrades that start from the lowest investment grade, BBB-, to travel more grades than those from neighboring grades. This would be consistent with the lower threshold of the NRSROs' grade BBB- being at a substantial default probability, but also could occur simply because downgrades to junk severely impair some firms' operations. A comparison of data from a non-NRSRO agency and an NRSRO shows that the latter's regrades from BBB-moved in the direction of the non-NRSRO's earlier ratings. This suggests the non-NRSRO defines its grade BBB- more narrowly than the NRSRO. JEL Classification: G2, G28, G14. Keywords: Credit rankings, default, Egan-Jones Ratings, prediction, Enron, California utilities. |
