The Central Bank of the Republic of Azerbaijan has adopted amendments to its prudential rulebook to enable banks to extend credit using behavioural models built from borrowers’ financial transaction data, including lending to individual entrepreneurs and individuals based on projected income. The framework sets requirements for behavioural model development, banks’ internal capacity in this area, model validation and reporting. It also introduces risk mitigants for loans originated via behavioural models, including limits, stricter classification requirements and increased capital requirements, and caps such lending at an aggregate of no more than 10% of a bank’s total loan portfolio. Banks must stop issuing new behavioural-model-based loans once loans more than 90 days past due reach 10% of the behavioural-model-based loan portfolio.
