Abstract

Analysing model documentation for 17 AIRB and FIRB credit risk models, this paper delivers IFRS 9 gap analysis of the existing models used for capital adequacy requirements. Based on the review of the IFRS 9 regulatory framework, the paper assumes that the use of the existing models may cause IFRS 9-related compliance gaps that render the existing models inadequate for the provisioning of expected losses. Recognising the potential IFRS 9 gaps, the paper addresses the question whether there is synergy between the AIRB and FIRB modelling approaches and the IFRS 9 rules. To this end, the paper confirms that the existing credit risk models cannot be re-used for IFRS 9 in their current forms.
