The EBA has published a Decision on the calculation of capital requirements as part of the Single Rulebook in banking which aims to ensure harmonisation in the EU in relation to the use of unsolicited credit ratings for determining institutions' own funds requirements. Institutions will be permitted to use these credit assessments for determining capital requirements where the EBA confirms those unsolicited ratings do not differ in quality from solicited ratings of that same ECAI. The Decision allows for the use of unsolicited ratings assigned by 22 ECAIs.
