The Basel Committee on Banking Standards launched a consultation on changes to the advanced internal ratings based approach and the foundation IRB approach so as to reduce variation in capital requirements for credit risk. The Basel Committee is proposing to: (i) remove the IRB approaches for certain portfolios which will then be subject to the standardized approach to credit risk; (ii) remove the option to use the advanced IRB approach for exposures to corporates that are part of consolidated groups that have annual revenues of more than EUR 200m; (iii) remove the IRB approaches for specialized lending that use banks' estimates of model parameters; and (iv) introduce a floor to the internal model method for counterparty credit risk based on a percentage of the applicable standardized approach. The consultation closes on June 24, 2016. The Basel Committee has committed to finalizing all the proposed changes to the IRB approaches by the end of 2016.
