Nigeria’s financial sector is set for a major regulatory shift as the Central Bank of Nigeria introduces stricter Bank Verification Number (BVN) controls aimed at reducing fraud, strengthening digital identity security, and tightening oversight of electronic banking transactions.
The new framework, which takes effect from May 1, 2026, introduces several far-reaching measures that will directly affect how millions of Nigerians access and manage their bank accounts, particularly through mobile and digital platforms.
At the center of the policy is a new BVN fraud monitoring system that allows banks to place accounts linked to suspicious activity on a temporary 24-hour watchlist.
During this period, transactions may be restricted or temporarily frozen while customers undergo additional verification.
According to the CBN, the measure is designed to stop fraudulent transactions in real time and prevent funds from being quickly moved out of compromised accounts.
The policy is expected to significantly strengthen Nigeria’s response to rising cases of identity theft, SIM swap fraud, and unauthorized account access.
SIM swap fraud, where criminals hijack a victim’s phone number to intercept banking alerts and one-time passwords (OTPs), has been identified as one of the fastest-growing threats to digital banking security in Nigeria.
The new BVN-linked restrictions are therefore expected to tighten control over phone number changes and identity verification processes across financial institutions.
Under the new rules, banks and payment service providers will also be required to intensify monitoring of BVN-linked transactions and flag unusual account behaviour more aggressively. Customers whose accounts trigger red flags may be contacted for immediate verification before any further transactions are allowed.
The policy forms part of a broader overhaul of Nigeria’s BVN system, which already serves as a central biometric identity linking customers to their bank accounts across the financial sector. With enrolment now estimated at over 68 million users, the BVN has become a critical tool for identity verification and anti-fraud enforcement.
Financial analysts say the new watchlist system reflects the CBN’s increasing reliance on real-time monitoring as digital banking adoption continues to grow rapidly across the country. While the reforms are expected to improve security, they may also lead to more frequent transaction delays or temporary account restrictions for customers flagged by the system.
Bank users are therefore being advised to ensure their BVN-linked information is up to date, particularly phone numbers and identity records, as discrepancies could increase the likelihood of account verification holds under the new regime.
Industry observers also note that the success of the policy will depend on how efficiently banks implement the real-time monitoring requirements and how quickly genuine customers can be cleared after being flagged.
As the May 1 deadline approaches, stakeholders expect increased public awareness campaigns from banks to help customers understand the new rules and avoid disruptions.
For millions of Nigerians, the coming changes mark a significant shift toward stricter digital banking oversight, with the CBN prioritizing fraud prevention and identity security over transactional convenience.
If fully enforced as planned, the new BVN watchlist and SIM swap restrictions could redefine how Nigerians interact with the banking system in the digital age.
