Money moves through Nigeria’s financial system at a speed that would have been unimaginable just a decade ago. With a few taps on a phone, millions of naira can travel across accounts, banks, and payment platforms in seconds.

The challenge for regulators has been: how do you track financial crime when money moves that fast?

The Central Bank of Nigeria (CBN) believes the answer lies in artificial intelligence.

For the first time, the Nigerian regulator has formally directed banks and financial institutions to begin deploying AI-driven monitoring systems to detect and prevent financial crimes such as fraud and money laundering.

The directive signals a major shift in how the country plans to monitor its rapidly expanding digital economy.

In essence, the CBN is acknowledging that the traditional approach, where compliance officers manually review thousands of transactions, is no longer sufficient for the scale and speed of modern financial activity.

Why the CBN Is Turning to Artificial Intelligence

Nigeria’s financial landscape has changed dramatically in recent years.

Mobile banking apps, instant transfers, fintech platforms, and digital wallets now handle millions of transactions daily. What once required physical bank visits can now be completed in seconds.

While this transformation has improved financial access and convenience, it has also created opportunities for criminals to move illicit funds quickly and discreetly.

Artificial intelligence offers a different way to monitor financial behaviour.

Instead of relying entirely on humans scanning transaction records, AI systems analyse patterns in financial data. They can detect unusual behaviour such as:

• transactions that suddenly increase in size

• repeated transfers between the same accounts

• unusual payment routes across multiple platforms

When something looks suspicious, the system automatically flags the activity for investigators to review.

However, the CBN emphasized that AI will not replace human oversight. Compliance officers and investigators will still examine flagged cases to confirm whether a crime has actually occurred.

What Banks and Fintech Companies Must Do

The new rules apply across Nigeria’s financial sector. Institutions affected include commercial banks, fintech companies, mobile money operators, international money transfer operators, and payment service providers.

Under the directive, these institutions must deploy automated systems capable of performing several critical tasks.

First, the systems must strengthen customer identity verification, ensuring that individuals opening accounts are properly identified.

Second, they must monitor financial transactions continuously, scanning activity for patterns that could indicate fraud or money laundering.

Third, institutions must screen customers against sanctions lists and politically exposed persons (PEPs); individuals who may present higher corruption risks due to their political influence.

Finally, the systems must track suspicious activity across multiple digital payment channels simultaneously, rather than treating each platform separately.

The objective is to build a more integrated monitoring system. Instead of examining isolated transactions, the technology evaluates a customer’s overall financial behaviour.

For example, if an account that typically transfers small amounts suddenly begins moving very large sums, the system may flag the activity for investigation.

Rising Fraud Is Driving the Policy Shift

One of the key reasons for the new directive is the growing scale of financial fraud in Nigeria.

Data from the Financial Institutions Training Centre (FITC) shows that fraud incidents have continued to rise alongside the expansion of digital banking, with 19,007 cases reported in Q3 2024, a 65% increase from Q2 2024, driven by digital channels.

Total fraud amounts surged 105% to ₦115.9 billion in Q3 2024, with mobile, computer or web, and POS fraud being the most prevalent.

In early 2025 alone, Nigerian banks recorded more than 12,000 fraud cases, with total losses estimated at about ₦3.29 billion.

The CBN has spent years introducing measures to strengthen financial security. Among the most significant reforms was the creation of the Bank Verification Number (BVN) system, which links bank accounts to a unique biometric identity.

The regulator also supported the creation of the Nigeria Electronic Fraud Forum, a platform that allows banks and financial institutions to share information about emerging fraud threats.

More recently, the CBN has tightened rules requiring banks to respond quickly to fraud reports and investigate suspicious transactions within strict timelines.

The integration of artificial intelligence represents the next stage in this evolving regulatory strategy.

When the New Rules Will Take Effect

The CBN is not requiring financial institutions to adopt the new systems immediately.

Instead, banks and financial service providers must first submit a detailed implementation plan explaining how they intend to integrate AI into their monitoring frameworks.

Once approved, institutions will be given time to comply:

• Deposit Money Banks: up to 18 months to fully implement the systems

• Other financial institutions: up to 24 months to comply

During this period, the CBN will supervise progress and conduct inspections to ensure institutions are meeting the new regulatory requirements.

A Turning Point for Financial Regulation in Nigeria

By formally integrating artificial intelligence into its anti-money laundering framework, Nigeria joins a growing group of countries using advanced technology to track financial crime.

For most bank customers, the change will be largely invisible.

Transfers will still be completed in seconds, and banking apps will function the same way they always have.

But behind the scenes, increasingly sophisticated monitoring systems will be analysing transactions in real time, watching patterns, flagging anomalies, and alerting investigators when something appears suspicious.

The goal is straightforward: to make Nigeria’s financial system faster for legitimate users and far more difficult for criminals to exploit.
