SEC: Report to Congress Credit Rating Standardization Study

The Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) was enacted on July 21, 2010. Title IX, Subtitle C of the Dodd-Frank Act, consisting of sections 931 through 939H and titled “Improvements to the Regulation of Credit Rating Agencies,” amended the Securities Exchange Act of 1934 (“Exchange Act”) to impose new self-executing requirements with respect to credit rating agencies registered with the U.S. Securities and Exchange Commission (“Commission”) as nationally recognized statistical rating organizations (“NRSROs”), requires that the Commission adopt rules applicable to NRSROs in a number of areas, and requires the Commission to conduct certain studies.

Section 939(h)(1) of the Dodd-Frank Act provides that the Commission shall undertake a study on the feasibility and desirability of:
  • standardizing credit rating terminology, so that all credit rating agencies issue credit ratings using identical terms;
  • standardizing the market stress conditions under which ratings are evaluated;
  • requiring a quantitative correspondence between credit ratings and a range of default probabilities and loss expectations under standardized conditions of economic stress; and
  • standardizing credit rating terminology across asset classes, so that named ratings correspond to a standard range of default probabilities and expected losses independent of asset class and issuing entity.
Section 939(h)(2) of the Dodd-Frank Act provides that the Commission shall submit to Congress a report containing the findings of the study and the recommendations, if any, of the Commission with respect to the study. This report is submitted to Congress pursuant to section 939(h)(2).

The Commission solicited public comment regarding the standardization that is the subject of this report, and Commission staff carefully reviewed the comments submitted by NRSROs, market participants, and others. Commission staff also reviewed publicly-available information on, among other things, the credit rating scales of NRSROs, and relevant studies and articles.

As an initial matter, several commenters argued that the Commission currently does not have the authority to require credit rating standardization because, by statute, the Commission may not regulate the methodologies NRSROs use to determine credit ratings. Regarding the subject matter of the study, commenters raised serious concerns about the feasibility and desirability of standardization and, in particular, most did not feel that standardization would lead to higher levels of accountability, transparency, and competition in the credit rating agency industry. Several commenters suggested that requiring increased transparency would be a more desirable alternative.

With respect to the specific topics identified in section 939(h)(1) of the Dodd-Frank Act, the staff found:
  • Although NRSROs use similar scales and symbols to denote long-term credit ratings, the number of rating scales and the rating symbols used vary widely among NRSROs for other types of credit ratings. Standardizing credit rating terminology may facilitate comparing credit ratings across rating agencies and may result in fewer opportunities for manipulating credit rating scales to give the impression of accuracy. Requiring such standardization, however, may not be feasible given the number and uniqueness of rating scales and differences in credit rating methodologies used by credit rating agencies. Further, requiring standardized credit rating terminology may reduce incentives for credit rating agencies to improve their credit rating methodologies and surveillance procedures.
  • Standardizing market stress conditions under which ratings are evaluated may not allow the stress conditions to be tailored to a particular type of credit rating or to be reevaluated and updated as appropriate. Different stress conditions may be appropriate for different asset classes.
  • Requiring a correspondence between credit rating categories and a range of default probabilities and loss expectations could lead to greater accountability among credit rating agencies. However, NRSROs do not provide such a correspondence because they base their credit ratings on a range of qualitative, as well as quantitative, factors. One credit rating agency that is not registered as an NRSRO does provide a .
  • Most NRSROs appear to believe that it is desirable for a credit rating agency to have a standardized credit rating terminology that applies across at least some asset classes. However, some studies suggest that credit ratings have not historically been comparable across asset classes.
  • Increasing transparency may be more feasible and desirable than implementing the standardization that is the subject of this study. In this regard, rulemaking initiatives mandated under the Dodd-Frank Act are designed to increase transparency with respect to the performance of credit ratings and the methodologies used to determine credit ratings.
The staff, based on the findings above, recommends that the Commission not take any further action at this time with respect to: (1) standardizing credit rating terminology, so that all credit rating agencies issue credit ratings using identical terms; (2) standardizing the market stress conditions under which ratings are evaluated; (3) requiring a quantitative correspondence between credit ratings and a range of default probabilities and loss expectations under standardized conditions of economic stress; and (4) standardizing credit rating terminology across asset classes, so that named ratings correspond to a standard range of default probabilities and expected losses independent of asset class and issuing entity. In addition, given the difficulties commenters identified with respect to implementing the standardization that is the subject of the study, the staff believes it would be more efficient to focus on the rulemaking initiatives mandated under the Dodd-Frank Act, which, among other things, are designed to promote transparency with respect to the performance of credit ratings and the methodologies used to determine credit ratings.
