PEP and Sanctions Screening Requirements in Nigeria

Sanctions screening in Nigeria requires financial institutions to check every customer against the United Nations Consolidated List and the Nigeria Sanctions List, at onboarding, before transactions, continuously, and every time a list changes. Screening for politically exposed persons runs alongside it, and a confirmed sanctions match triggers an immediate freeze without notifying the customer.

Both sit inside the wider AML screening a Nigerian institution runs, and they answer different questions about the same person. Sanctions screening asks whether the law forbids you from dealing with this customer at all. Politically exposed person screening asks whether you can deal with them, but with greater care and senior approval.

What Are the PEP and Sanctions Screening Requirements in Nigeria?

Nigerian institutions must meet five sanctions screening requirements: screen customers against the designated lists, screen continuously rather than once, identify politically exposed persons and their associates, freeze and report confirmed matches without delay, and keep evidence of every match and every dismissal.

These are not internal policy choices. Each duty sits in law or in a CBN regulation, and each carries a penalty. The duty to freeze, in particular, allows no review window and no customer conversation first.

The requirements apply to banks, other financial institutions, payment service providers, mobile money operators and designated non-financial businesses, which means a fintech carries the same screening obligations as a tier-one bank.

Which Laws Require Sanctions Screening in Nigeria?

Financial institutions in Nigeria must screen customers and transactions against domestic and international watchlists under the following 4 regulatory framework or law: the Terrorism (Prevention and Prohibition) Act 2022, the Money Laundering (Prevention and Prohibition) Act 2022, the CBN Customer Due Diligence Regulations 2023, and the CBN Guidelines on Targeted Financial Sanctions issued in 2022.

The CBN Baseline Standards for Automated AML Solutions, issued in March 2026, then set how the screening system itself must work. The full regulatory map is in our guide to AML regulations in Nigeria.

Which Lists Must Sanctions Screening Cover?

Sanctions screening must cover two lists as a minimum: the United Nations Consolidated List and the Nigeria Sanctions List maintained by the Nigeria Sanctions Committee. Institutions with cross-border exposure usually screen further.

The notice rule catches institutions out. Once a designation is published by NIGSAC, the obligation starts, whether or not an email reached your compliance inbox. List monitoring therefore has to be a managed process with an owner, not something a person checks when they remember. Our daily sanctions monitor tracks changes across authorities on the day they land.

Who Is a Politically Exposed Person in Nigeria?

A politically exposed person is someone entrusted with a prominent public function, along with their immediate family members and close associates. The category covers three groups: domestic politically exposed persons holding office in Nigeria, foreign ones holding office abroad, and people holding senior positions in international organisations.

Typical examples include heads of state and government, senior politicians, senior government, judicial or military officials, senior executives of state-owned corporations, and important political party officials. Family members and close business associates fall within scope because they are the usual route for moving funds on a politically exposed person's behalf.

CBN guidance adds a default that matters in practice: most domestic politically exposed persons are treated as high risk. Institutions sometimes assume the enhanced requirements apply only to foreign officials, which leaves a large part of a Nigerian bank's book under-screened.

Being a politically exposed person is not an accusation and not a reason to refuse service. It is a risk classification that triggers deeper checks and closer monitoring.

When Must Sanctions Screening Be Carried Out?

Sanctions screening must happen at five points: before a relationship is established, before transactions are processed, on an ongoing basis for existing customers, every time a list is updated, and whenever a customer's circumstances change.

The list-update trigger is the one that creates the most work and gets missed most often. A designation published today applies to customers onboarded years ago, so the only way to comply is to run the new list across the entire book rather than the day's new traffic.

Change of circumstance matters for politically exposed persons specifically. A customer who was ordinary last year may be appointed to office this year. CBN guidance requires institutions to reassess the risk when that happens, apply enhanced measures where the customer is now high risk, and adjust transaction monitoring to match.

What Must a Bank Do When Sanctions Screening Returns a Match?

A confirmed match obliges four actions under section 54 of the Terrorism (Prevention and Prohibition) Act 2022: freeze without delay and without prior notice, report the freeze to the NIGSAC Secretariat, file a suspicious transaction report with the NFIU, and report attempted transactions as well as completed ones.

1. Freeze First: No Delay, No Prior Notice

Identify and freeze all funds, assets and economic resources owned or controlled by the designated person or entity. The freeze reaches beyond account balances to debts, insurance interests and interests in a sole trader or partnership. Telling the customer in advance is prohibited.

2. Report to NIGSAC: What You Froze and When

Report the freeze and any other action taken to the Secretariat of the Nigeria Sanctions Committee, with enough detail to identify the accounts, values and timing of each step.

3. File With the NFIU: A Separate Obligation

File a suspicious transaction report with the NFIU immediately. The freeze report and the suspicious transaction report are separate duties, and completing one does not discharge the other.

4. Capture Attempted Transactions: The Ones That Did Not Complete

A blocked transfer that never settled is intelligence the authorities want. Institutions that report only completed activity leave a gap that surfaces during examination.

What Does Sanctions Screening Require for Politically Exposed Persons in Nigeria?

Where screening identifies a politically exposed person, three additional steps apply: senior management approval before the relationship begins or continues, reasonable measures to establish source of funds and source of wealth, and enhanced ongoing monitoring of the relationship.

Senior approval needs a name attached to it. An enhanced due diligence file with no identifiable approver is a gap examiners find quickly. Source of funds and source of wealth are also separate questions: one explains the money in this transaction, the other explains how the customer built their assets overall.

Record why the classification was made, including the position held, the country and the period in office. A classification with no reasoning behind it is hard to defend later. Our guide to customer due diligence in Nigeria covers the wider enhanced due diligence process.

Why Does Sanctions Screening Fail in Practice?

Sanctions screening typically fails for five reasons: incomplete alias coverage, slow list refresh, an existing customer book that is never rescreened, false positive thresholds tuned for convenience, and ownership structures that hide a designated party.

1. Alias Coverage: Names Loaded in One Form Only

Designated parties carry alias forms, transliterations and non-Latin script variants. Records loaded on legal name alone miss them, and alias coverage is the single most common failure found in screening reviews. Test your system with known designated names in their alias forms before an examiner does it for you.

2. List Refresh: The Gap Between Publication and Production

Measure how long it takes for a published designation to reach your live screening system. That gap is where liability sits, because the obligation starts at publication, not at the point your vendor updates the file.

3. The Existing Book: Screening Only New Customers

Many systems screen onboarding traffic well and rescreen the back book rarely. Since designations apply to existing relationships, this is the most consequential gap of the five.

4. False Positives: Thresholds Tuned to Reduce Noise

Loosening match thresholds reduces alerts and reduces detection at the same time. Set the thresholds deliberately, document who approved them and why, and keep the before and after whenever they change.

5. Ownership: The Entity the Notice Never Names

Sanctions regimes commonly extend to entities owned or controlled by a designated party, so screening the named entity alone is not enough. Resolve corporate customers to their ultimate owners and rerun ownership resolution when new designations land.

How Should Sanctions Screening Work Under the CBN Baseline Standards?

The CBN Baseline Standards require screening systems to do four things: connect to domestic and international watchlists with real-time or near real-time updates, apply fuzzy and AI-based name matching, support adverse media screening, and block transactions automatically when a match is confirmed. Banks must comply fully by 10 September 2027 and other financial institutions by 10 March 2028.

Two further requirements apply to the sanctions screening function. Every configuration change and alert decision must sit in a tamper-proof audit trail, and any machine learning model used in matching must be explainable and independently validated at least once a year.

Implementation roadmaps were due to the CBN Compliance Department by 10 June 2026, which means supervisors already hold each institution's plan and can test screening capability against the milestones it sets.

What Reports Follow a Sanctions Screening Action?

Three reports follow a sanctions screening action: an immediate freeze report to NIGSAC, an immediate suspicious transaction report to the NFIU, and quarterly returns on targeted financial sanctions actions to the CBN within 10 days of each quarter end.

The quarterly return is the one most often missed, because nothing inside the institution triggers it when there is no activity to report. Treat it as a standing calendar item with a named owner, nil returns included.

What Are the Penalties for Sanctions Screening Failures?

Penalties for sanctions screening failures run on two tracks. Sector regulators are required under section 54 of the Terrorism (Prevention and Prohibition) Act 2022 to impose administrative sanctions on institutions that fail to implement targeted financial sanctions, and the CBN can act under the Banks and Other Financial Institutions Act 2020.

The exposure is already visible in the numbers. A review of annual reports by Prime Business Africa found the CBN fined nine listed banks about ₦17.35 billion in 2024, with anti-money laundering findings and breaches of targeted financial sanctions and screening rules among the reported infractions.

Screening failures were tested in the open in April 2026, when the Federal Government designated 48 individuals and 12 entities and directed institutions to block all associated transactions. Any institution whose screening missed a name, or whose freeze took days rather than hours, produced a finding it has to explain.

Running PEP and Sanctions Screening in Nigeria With Youverify

Meeting Nigeria's sanctions screening and politically exposed person requirements takes three things: matching that catches alias and non-Latin script forms, lists that reach production the day they are published, and a record of every match and dismissal. Youverify provides all three for Nigerian banks, fintechs and payment providers.

Customer Onboarding runs document, anti-deepfake liveness and government-source checks in one journey, scored to a risk tier, with sanctions and politically exposed person screening inside the same flow. A customer who belongs on the enhanced path is identified before the account opens, against a verified identity rather than a typed name.

Transaction Monitoring applies rules and models on live flows, with typologies tuned to multi-currency, mobile money and cross-border corridors, so a designated party's activity is visible across the relationship and not only at onboarding. When a match is confirmed, Case Management holds the queues, SLAs, the entity graph, evidence and a decision trail you can hand to an examiner, covering both the freeze and the alerts you cleared.

The freeze decision stays with your compliance team, as the Act requires. Youverify makes sure the match surfaces, the clock starts on time and the evidence survives. Request a screening review with our compliance team and see what your current setup would have caught in April 2026.
