Insider Fraud Crisis Costs Nigerian Banks N52.26 Billion

The Nigerian banking sector is facing a severe crisis of insider fraud, with reported losses of N52.26 billion in 2024. This represents a 350% increase in fraud losses over five years, despite a decrease in the volume of fraud incidents.

Employees, such as Wahab Adeyinka, exploit their legitimate access to bank systems to facilitate fraudulent transactions, including diverting funds from customer accounts. A notable case involved Adeyinka manipulating processes to transfer funds through 34 intermediary accounts, leading to a loss of N12 billion.

The Economic and Financial Crimes Commission (EFCC) has charged several employees, including Samuel Ihechukwu Asiegbu and others, with conspiracy to commit fraud. The Nigeria Deposit Insurance Corporation (NDIC) has raised alarms about the increasing trend of insider fraud, with a significant rise in cases reported from 2016 to 2018.

The financial impact of these frauds is devastating, leaving thousands of customers financially devastated and highlighting systemic vulnerabilities within the banking infrastructure.
