Case Study: Rand Merchant Bank achieves centralized, auditable credit risk ratings with ACTICO's Credit Risk Rating Platform

Rand Merchant Bank - Customer Case Study

Rand Merchant Bank (RMB), a division of FirstRand Bank Limited and a leading African investment bank, needed to replace its spreadsheet-based credit rating models to meet advanced IRB regulatory requirements under Basel II. The bank sought a centralized, auditable rating system that could host all internal PD and LGD models, provide a historical data repository for portfolio modeling and stress testing, and integrate seamlessly with existing loan origination and other internal/external systems. RMB selected ACTICO’s Credit Risk Rating Platform to address these challenges.

ACTICO implemented the Credit Risk Rating Platform (based on ACTICO Rules), enabling graphical implementation of rating models as rule trees and decision tables, automated testing, backtesting, and autogenerated documentation and executable rating services for third-party integration. The solution put model maintenance in the hands of RMB’s business analysts without programming, delivered a central auditable data repository, supported deployment of PD and LGD models, and improved risk assessment and regulatory compliance—helping RMB meet its regulatory obligations and speed up model development and rollout.
