AML Compliance for Microfinance Banks in Nigeria: What MFBs Must Know in 2026
Microfinance banks in Nigeria are not exempt from AML obligations. With the CBN's 2026 Baseline Standards now active, every MFB, regardless of size, must implement automated transaction monitoring, KYC processes, and goAML reporting. This guide explains what's required and how to comply.
Do AML Rules Apply to Nigerian MFBs?
Yes, unambiguously. All CBN-licensed microfinance banks are subject to the Money Laundering (Prevention and Prohibition) Act, CBN AML/CFT regulations, and the 2026 Baseline Standards for Automated AML Solutions. The CBN has made clear that MFBs are within scope and will be examined accordingly.
Core AML Requirements for Nigerian MFBs
Tiered KYC Implementation
MFBs must implement CBN's tiered KYC framework, Tier 1 (basic BVN), Tier 2 (NIN/ID), Tier 3 (full CDD), across all customer accounts.
Real-Time Transaction Monitoring
Automated monitoring of all transactions for suspicious patterns, even low-value MFB transactions must be monitored for structuring, velocity, and anomalous behaviour.
STR Filing via goAML
Any suspicious activity must be reported to the NFIU within 24 hours via goAML. No minimum threshold applies, it is based on suspicion alone.
CTR Filing for Cash Transactions
Cash transactions of ₦5M+ (individual) or ₦10M+ (corporate) must be reported, even for MFB-scale operations.
Customer Risk Profiling
Each customer must be assigned a risk tier. High-risk customers require Enhanced Due Diligence and more frequent review.
Staff Training
All frontline and operations staff must receive AML/CFT training annually. Training records must be maintained for CBN examination.
Board AML Policy
A formal AML/CFT policy approved at board level is required, along with a designated Money Laundering Reporting Officer (MLRO).
Unique AML Challenges for Nigerian MFBs
High Transaction Volume, Low Value
Many MFBs process thousands of small transactions daily. Manual review is impossible, automated monitoring is essential.
Limited Compliance Resources
Many MFBs lack dedicated compliance teams. Automated tools must compensate, reducing manual burden.
Cash-Heavy Operations
MFBs often operate in cash-intensive environments, requiring careful CTR monitoring and cash transaction controls.
Informal Economy Customers
Customers from informal sectors require careful risk profiling. Standard CDD templates may need adaptation.
