ESAs（欧州証券機構）、ECAI（適格格付機関）の信用力評価のマッピングに関する技術的基準案について市中協議、意見受付期限は5月5日

The ITS will be part of the Single Rulebook in banking aimed at enhancing regulatory harmonisation across the EU. The consultation runs until 5 May 2014. Capital requirements under the Standardised Approach are based, among other factors, on the credit quality of the exposure, which is calculated on the basis of credit assessments provided by ECAIs. These draft ITS specify the elements that should be taken into consideration to determine the correspondence (‘mapping’) between risk weights and credit assessments provided by a particular ECAI.

This ‘mapping’ has to be provided for all ECAIs, as defined by the Capital Requirements Regulation (CRR), including any credit rating agency that is registered or certified in accordance with the Regulation on Credit Rating Agencies (CRA) or a central bank issuing credit ratings that are exempt from the application of the CRA Regulation.

In particular, the following elements have been taken into account in the mapping process:

• Specific requirements have been established for the calculation of the default rate, which should improve the objectivity and consistency of the ‘mappings’;
• Default experience obtained from external ratings of other ECAIs or credit scores produced by the ECAIs themselves have been considered;
• In case no external or internal default rate data is available, an estimate of the quantitative factor has been required based on the assessment provided by the ECAIs; In addition, a description of the implementation of the qualitative factors has been provided in the explanatory boxes of these draft ITS.

The proposed draft ITS have been developed on the basis of Regulation 575/2013 of the European Parliament and of the Council of 26 June 2013 on prudential requirements for credit institutions and investment firms. The EBA is expected to submit these draft ITS to the European Commission by 1 July 2014.
