Customer Risk Ratings (CRRs) have long been integral to anti-money laundering and counter-terrorist financing (AML/CFT) frameworks.
According to Consilient, despite their importance, many financial institutions continue to use outdated CRR models based on static information, subjective human judgment, and legacy assumptions. The result? Misclassified customers, operational inefficiencies, and increasing regulatory pressure.
In collaboration with Richard Hills from K2 Integrity, Consilient detailed that new insights are emerging around building more accurate, transparent, and scalable CRRs. By embracing behavioural data, machine learning (ML), and privacy-preserving collaborative models, institutions can develop smarter and more resilient AML systems to better tackle today’s evolving risks.
Traditional CRR models suffer from well-known flaws. Institutions relying on static KYC data, manual scoring matrices, and subjective interpretation face challenges including inconsistency, limited behavioural insight, lack of transparency, and bias. These problems have caught regulators’ attention: the FCA has criticised oversimplified CRR models in the UK’s AML systems, while FinCEN’s enforcement actions in the U.S. have pointed to deficiencies in customer risk assessments.
CRRs are more critical than ever, shaping customer lifecycle management well beyond simple regulatory compliance. Done correctly, CRRs enable institutions to identify high-risk customers efficiently, apply proportional due diligence, reduce false positives, and maintain transparent audit trails. Poorly rated customers, however, create inefficiencies and expose firms to significant regulatory risks.
Machine learning provides a powerful opportunity to modernise CRR methodologies. Instead of depending solely on KYC snapshots, ML models assess dynamic behavioural patterns such as transaction activity, geographical movement, and network connections to detect indicators of elevated risk. Unlike manual processes, ML models learn from data rather than assumptions, improving both consistency and detection capabilities.
