Where Sukuk are externally rated, Islamic bank licensees must apply the relevant risk weight given in Paragraph CA-8.4.3 based on the ECAI ratings from recognised agencies listed in Section CA-4.6. Where there are no acceptable ECAI ratings, the RWs will be 1,250% (as shown on table CA-8.4.3) or determined on the basis of the underlying assets as shown in the remainder of this Section for the different types of Sukuk (which may involve market risk as well as credit risk).
