INSIDER FRAUD CRACKDOWN: NIBSS DEMANDS STAFF PROFILING, JOB ROTATION AND LIFESTYLE CHECKS AT BANKS

• Nigeria’s banking sector is facing a tougher internal fraud test as the Nigeria Inter-Bank Settlement System, NIBSS, calls on financial institutions to tighten controls around employees with access to sensitive financial systems, accounts and transaction processes.

The warning was issued in January 2026 as authorities and industry leaders intensified efforts to contain electronic fraud and prevent insiders from exploiting weaknesses within financial institutions.

At the centre of the intervention is a renewed push for non-technical safeguards, including staff profiling, job rotation, mandatory leave, lifestyle checks and intelligence sharing across institutions.

NIBSS Managing Director and Chief Executive Officer, Premier Oiwoh, warned that insider involvement remains a significant concern, with investigations showing that fraud can involve current and former bank employees. He also criticised the failure of institutions to report fraud incidents, warning that perpetrators can move between financial institutions when misconduct is not properly documented and shared.

The warning came as NIBSS, working with the Central Bank of Nigeria, the Nigerian Financial Intelligence Unit and security agencies, strengthened the Person of Interest Portal by integrating industry watchlists, politically exposed persons databases and customer account information to support fraud monitoring and prevention.

Oiwoh also pointed to technology driven controls, including real time risk scoring of instant payments and the flagging of suspicious transactions.

But the NIBSS chief made clear that technology alone cannot close the insider threat. He urged financial institutions to strengthen staff related controls through profiling, rotation, mandatory leave, lifestyle checks and intelligence sharing.

His warning was blunt:“If you cannot afford to secure a financial institution properly, you should not operate one.”

The intervention carries a wider compliance implication. Job rotation and mandatory leave can disrupt prolonged control over sensitive processes, while staff profiling and lifestyle checks can provide additional risk indicators when used within appropriate employment, privacy and legal safeguards.

The intelligence sharing component is equally critical. Where fraudsters can leave one institution and obtain access to another without their history following them, the control environment remains fragmented.

The January crackdown therefore points to a broader shift in Nigerian banking compliance. Insider risk is increasingly being treated as a financial crime and governance issue, not merely an internal disciplinary matter.

For banks, the message is increasingly direct. Strong passwords, transaction monitoring and artificial intelligence cannot compensate for weak human controls. The real test is whether institutions can detect when legitimate access is being turned into an instrument of fraud.
