The assignment of risk weights for exposures is contingent upon the availability of credit assessments from nominated External Credit Assessment Institutions (ECAIs). According to Article 136, exposures with a credit rating available will align with specific risk weights as detailed in Table 1. Credit quality steps range from 20% for the highest quality to 150% for lower ratings.

In instances where no credit assessment is available, a standard risk weight of 100% applies. This framework underscores the importance of adequate credit evaluations in managing risk exposure, thereby facilitating regulatory compliance and informed risk management strategies.
