Under the 2026 AML/CFT/CPF regulations, every bank and fintech in Nigeria is required to use AI-driven monitoring to flag ‘Suspicious Transactions.’ An STR (Suspicious Transaction Report) is filed when a payment doesn’t match your known business profile. In 2026, ‘False Positives’ have increased, making it vital for SMEs to prepare for regulatory scrutiny.
What Triggers an STR in 2026?
It’s not just about ‘large’ sums; it’s about ‘atypical’ behavior. If your business usually processes ₦100,000 transactions and suddenly receives ₦20 million from an unknown source, the system triggers an alert. You must be familiar with the reporting requirements for financial transactions to proactively justify large inflows.
Top 2026 STR Triggers:
- Structuring: Breaking a large payment into many small transfers under ₦10,000.
- Rapid Movement: Funds arriving and being transferred out within minutes (‘Flow-through’ accounts).
- Unknown UBO: Transactions involving entities where the beneficial owner is hidden.
The “No-Tip-Off” Rule
In 2026, if a bank flags your transaction, they are legally barred from telling you they filed an STR. Your account might simply be “restricted” while they investigate. This is why maintaining a clean AML compliance framework is your only defense against sudden account freezes.
Step-by-Step: Avoiding Account Restrictions
- Update Your KYC Annually: Tell your bank about your projected turnover so large payments are expected.
- Provide ‘Source of Wealth’ Documents: Keep invoices and contracts ready for every inflow above ₦5 million.
- Screen Your Vendors: Use the ‘B’Odogwu’ equivalent for corporate verification to ensure your suppliers aren’t on a watch list.
- Proactive Disclosure: If you are expecting a massive one-off payment (e.g., an investment or property sale), notify your account officer in advance.
Practical Example: The Real Estate Agent
‘Lekki Realty’ received a ₦50 million deposit for a land sale. Because the buyer was a new entity, the bank flagged it as suspicious. Because the agency had a pre-filed ‘Project Sales Agreement’ and a valid SCUML certificate, they resolved the flag in 24 hours without the account being frozen.
