Proprietary Methodology

Nigerian AML
Risk Scoring Model™

A structured, multi-factor risk scoring methodology calibrated for the Nigerian banking environment, aligned to CBN AML/CFT Regulations and FATF's risk-based approach.

What is the Nigerian AML Risk Scoring Model™?

The Nigerian AML Risk Scoring Model™ is a proprietary multi-factor framework developed by AI Shield Nexus to assign dynamic, continuously updated risk scores to customers, transactions, and relationships within the Nigerian financial system.

Unlike generic global risk models, it is calibrated specifically for Nigerian transaction patterns, regulatory thresholds, fraud typologies, and the CBN's risk-based supervision expectations, producing more accurate scores and fewer false positives.

Five Scoring Dimensions

Composite score (0–100) calculated as a weighted average across all dimensions

01. Customer Risk

Weight: 30%
Identity verification tier (Tier 1–3 KYC)
BVN/NIN validation status
PEP & sanctions screening result
Beneficial ownership complexity
Account age and tenure

02. Geographic Risk

Weight: 20%
Customer residential jurisdiction
Transaction origination state
Cross-border transaction corridors
FATF grey/black-listed countries
NFIU high-risk jurisdiction indicators

03. Transaction Risk

Weight: 25%
Transaction value vs. Naira thresholds
Deviation from baseline behaviour
Structuring pattern detection
Round-amount frequency
Velocity and frequency spikes

04. Channel Risk

Weight: 15%
Transaction channel (USSD, NIP, ATM, branch)
New device or SIM indicators
After-hours activity patterns
Multiple channel switches

05. Product & Relationship Risk

Weight: 10%
Product type (current, savings, domiciliary)
Correspondent banking relationship
Business sector risk classification
Customer-to-customer transfer exposure

Risk bands & required actions

Risk Band (Score)Required Compliance Action
Low (0–30)Standard CDD, periodic review (annual)
Medium (31–60)Enhanced monitoring, 6-month review cycle
High (61–80)EDD required, 3-month review, senior approval
Critical (81–100)Immediate case creation, possible account freeze, SAR consideration

AI enhancement layer

Beyond static rule-based scoring, the model incorporates a machine learning layer that analyses behavioural baselines and detects deviations over time. This means risk scores evolve dynamically, a customer who was low-risk at onboarding can be re-scored in real time if behaviour changes significantly.

Behavioural baseline modelling

Establishes normal transaction patterns per customer segment and flags meaningful deviations.

Peer group benchmarking

Compares customer behaviour against similar cohorts to surface outliers with greater precision.

Adaptive thresholds

Risk thresholds adjust automatically based on seasonal patterns, economic conditions, and fraud trends.

Explainable outputs

Every score change is accompanied by a plain-language explanation for investigator review and audit documentation.

Frequently asked questions

What is the Nigerian AML Risk Scoring Model™?

The Nigerian AML Risk Scoring Model™ is a multi-factor framework developed by AI Shield Nexus to assign dynamic risk scores to customers, transactions, and relationships within the Nigerian financial system. It combines rule-based triggers with AI-driven behavioural analytics.

How is risk scored in the Nigerian context?

Risk is scored across five dimensions: customer risk, geographic risk, transaction risk, channel risk, and product risk. Each dimension carries weighted inputs calibrated for Nigerian regulatory standards and common fraud patterns.

How does the model align with CBN regulations?

The model is calibrated to the CBN Risk-Based Supervision Framework, CBN AML/CFT Regulations 2022, and FATF's risk-based approach guidance, ensuring that scoring outputs align with regulatory examination expectations.
