La metodología de rating “through the cycle”: aplicación para la estimación de ratings soberanos
This paper analyses the through-the-cycle rating concept; basically, we try to specify its main characteristics, focusing on the differences with point-in-time ratings. We also discuss the effects of this methodology on the prediction power of default probabilities, on the stability of those ratings, and their impact on the capital requirements that emerge from Basel II, in terms of their potential procyclicality. On the other hand, we argue how predictable rating changes are, and the ability of the agencies to look through the cycle when assigning qualifications. Based on that, we conclude about the way that economical fundamentals must be incorporated in rating calculations. We estimate a panel data model with random effects ordered probit, using data for the period 1997-2007.
