CBN CRACKS DOWN ON BANK FRAUD: TIER 1 BANKS GIVEN 30 MINUTES TO CONTAIN DIGITAL THEFT

Nigeria’s banking sector is facing a new fraud response deadline as the Central Bank of Nigeria, CBN, pushes major banks to bring fraud dispute response and containment times below 30 minutes, in a move designed to improve asset recovery and prevent stolen funds from moving beyond the reach of financial institutions.

The directive places greater pressure on major tier 1 institutions, including Access Bank, Zenith Bank and United Bank for Africa, UBA, to respond to suspected fraudulent transactions at digital speed. The CBN announced the position during the 2026 Nigeria Electronic Fraud Forum, NeFF, technical kick off session in Lagos, stressing the need for faster and more coordinated responses as electronic fraud becomes increasingly sophisticated.

The shift marks a significant change in the fraud control environment. A response measured in hours can give criminals enough time to layer transactions, move funds across institutions, convert stolen money into other assets or route proceeds through accounts controlled by third parties.

A sub-30-minute containment window therefore puts operational resilience at the centre of fraud risk management. Banks will need stronger real time transaction monitoring, faster escalation channels, automated alerts and closer coordination across fraud teams, payment operators and other financial institutions.

The directive also raises questions about whether existing fraud response structures can operate at the speed required by Nigeria’s increasingly digital financial system. Detection alone is no longer sufficient. The critical compliance test is what happens in the minutes immediately after a suspicious transaction is identified.

For banks, the message from the regulator is clear. Fraud prevention must move from retrospective investigation towards real time intervention. The faster suspicious funds can be identified, frozen and traced, the greater the prospect of recovery and the lower the risk of wider financial system leakage.

The CBN’s wider payments supervision framework already emphasises real time monitoring and fraud prevention controls, reinforcing the regulator’s expectation that financial institutions should build systems capable of detecting and responding to electronic fraud rapidly.
