CBN Tightens Scrutiny of Banks Over Terrorism Financing Risks

Money can move quickly. That is one of the biggest strengths of a modern financial system, but it is also one of its vulnerabilities.

The Central Bank of Nigeria is now putting a sharper lens on one of the ways that financial channels can be abused.

The apex bank has elevated terrorism-financing supervision to a current supervisory priority, signalling increased scrutiny of banks and other regulated financial institutions as Nigeria strengthens efforts to prevent illicit actors from exploiting the financial system.

The announcement, issued on September 8 by the CBN's Acting Director of Corporate Communications and Investor Relations, Hakama Sidi-Ali, places four areas at the centre of the regulator's attention: terrorism-financing risk management, transaction monitoring, implementation of targeted financial sanctions and the reporting of suspicious transactions linked to terrorism financing.

For banks, this is more than another compliance notice.

It means the systems they use to understand where money is coming from, where it is going and whether a transaction raises a red flag will face closer regulatory attention.

A closer look at the money trail

The CBN says it will continue using a risk-based approach, combining on-site examinations with off-site monitoring to assess the effectiveness of anti-money laundering, counter-terrorism financing and counter-proliferation financing controls across the financial sector.

In practical terms, banks and other regulated institutions are expected to have systems capable of identifying unusual activity, escalating suspicious transactions and complying with applicable financial sanctions.

That does not mean every unusual transaction is automatically linked to terrorism financing. Rather, financial institutions are expected to identify transactions or patterns that warrant further review and take the appropriate action under existing rules.

This distinction matters because the financial system handles millions of legitimate transactions every day.

The challenge for banks is therefore not simply to monitor more transactions. It is to become better at identifying the transactions that genuinely require attention without unnecessarily disrupting legitimate customers.

Why sanctions matter

Targeted financial sanctions are another important part of the CBN's latest focus.

When individuals or entities are formally designated under applicable sanctions regimes, financial institutions may be required to restrict access to funds or economic resources connected to them.

The CBN had already taken a step in this direction in June, directing banks and other regulated financial institutions to implement sanctions relating to terrorism-financing designations issued by Nigerian and United States authorities.

The latest announcement therefore builds on measures already being implemented rather than introducing an entirely new compliance obligation.

It signals that the regulator now wants to pay closer attention to how effectively those controls work in practice.

What this means for banks and fintechs

Although the announcement is coming from the CBN, the implications extend beyond traditional commercial banks.

Ngeria's financial ecosystem now includes payment service providers, mobile money operators, international money transfer operators, fintechs and other regulated financial businesses. CBN's existing AML/CFT framework covers a broad range of financial institutions and payment-sector participants.

As financial services become increasingly digital, monitoring financial activity also becomes more complicated.

Transactions can move between bank accounts, payment platforms, wallets and other channels within seconds. That makes effective monitoring, identity verification, sanctions screening and suspicious-transaction reporting increasingly important.

For financial institutions, stronger supervision could therefore mean more investment in compliance technology, staff training, transaction-monitoring systems and internal controls.

It could also mean greater regulatory consequences for institutions whose controls are found to be inadequate.

And what about the everyday customer?

For most customers, the immediate effect may not be dramatic.

People will still be able to transfer money, receive payments, pay bills and use their banking and financial applications as usual.

But customers may encounter additional checks when transactions appear unusual or fall within areas that require enhanced scrutiny.

That can sometimes mean requests for additional information or delays while a transaction is reviewed.

The broader objective, however, is straightforward: keep legitimate money moving while making it harder for illicit funds to move through the formal financial system unnoticed.

That balance will be important as Nigeria continues to expand its digital financial ecosystem.

A wider financial integrity push

The CBN said the stronger supervisory focus also supports Nigeria's domestic and international cooperation on counter-terrorism financing, counter-proliferation financing and financial integrity.

The latest move fits into a wider pattern of tighter financial-sector controls introduced by the regulator in recent months, including measures around fraud monitoring, identity management, sanctions compliance and automated AML/CFT/CPF systems. The CBN has also previously issued baseline standards for automated systems designed to detect, analyse and report suspicious financial activity.

For Nigeria, the issue goes beyond individual banks.

A financial system trusted by customers, investors and international partners must be capable of showing that it knows who is using it, understands how money is moving through it and can respond when transactions raise legitimate concerns.

That is the standard the CBN is now signalling more clearly.

And as the regulator puts terrorism-financing supervision higher on its agenda, banks and other financial institutions will have to show that their safeguards do more than exist on paper.

They must work.

For customers, that may mean a financial system that asks a few more questions when something looks unusual.

For institutions, it means getting much better at knowing when to ask them.
