Abstract

There has been a net propensity over the last decade for the dominant rating agency of the U.S. insurance industry, A.M. Best, to downgrade property-liability insurers. This could reflect a general deteriorating credit worthiness of the industry or an increase in the performance thresholds Best's has deemed necessary to achieve a given rating class. Consistent with a recent study of corporate bond ratings, we find evidence there has been an increase in rating stringency. Specifically, we show pressure for insurers to maintain their existing ratings provides a plausible explanation of the dramatic buildup of capital in the industry during the 1990's. In addition, our analysis suggests Best's raised the bar in terms of the capital required to maintain the highest ratings differentially relative to the increase in standards they required for lower rated categories. The actual pattern of capital buildup across firms in different rating categories is consistent with an attempt by high quality firms to defend these ratings.
