Basel III Internal Rating Based Approaches (IRB) for Credit Risk

The Saudi Arabian Monetary Agency’s Banking Supervision Department mandates licensed financial institutions to implement the Internal Rating Based (IRB) approaches for credit risk. This directive operationalizes Basel III standards by requiring banks to calculate regulatory capital using internally derived probability of default and loss given default parameters. Institutions must integrate these IRB methodologies into their risk management frameworks to ensure accurate capital adequacy assessments and consistent regulatory compliance.
