EXPLAINER: Why Banks Must Meet CBN’s April 1 Stress Test Deadline

By Abah Margaret

The Central Bank of Nigeria (CBN) has directed all banks to commence stress testing from April 1, 2026, with a mandatory submission deadline of April 30, 2026. The directive marks a significant shift in regulatory oversight and underscores the apex bank’s push to strengthen the financial system. Here’s why the deadline is critical:

Shift to Risk-Based Capital Requirements
The CBN is transitioning from a fixed capital requirement framework to a risk-based model. Under this approach, banks’ capital adequacy will reflect the actual risk profile of their loan portfolios rather than a uniform benchmark. Failure to meet the deadline could leave banks operating without updated, regulator-approved capital positions, exposing them to sanctions.

Safeguarding Financial Stability
Stress testing enables regulators to assess how banks can withstand extreme economic conditions such as recessions or widespread loan defaults. By meeting the deadline, banks demonstrate that:

• Their balance sheets are resilient
• Newly raised capital is sufficient to absorb potential shocks

Mandatory Regulatory Compliance
Submission of stress test results is compulsory, with banks required to present Board-approved reports by April 30. Non-compliance may result in:

• Regulatory penalties
• Operational restrictions
• Reputational risks

Driving Nigeria’s Economic Ambitions
The stress testing exercise aligns with broader efforts to position Nigeria’s banking sector to support the country’s $1 trillion economy target by 2030. Banks that fail to comply risk weakening their capacity to finance large-scale infrastructure and development projects.

Expert Advisory on Compliance
Speaking during a webinar hosted by DataPro, Enterprise Risk Management (ERM) expert, Idris Adeleke, urged banks to act swiftly in preparing for the exercise. He emphasized the need for immediate portfolio analysis once March 31 financial data becomes available.

Adeleke advised banks to prioritise data gathering, ensure proper migration of credit exposures, and foster collaboration across risk, finance, and compliance teams to meet the strict deadline.

He explained that stress testing evaluates a bank’s resilience under severe economic scenarios, including market crashes and downturns. According to him, the CBN’s framework introduces stringent assumptions that could significantly impact Capital Adequacy Ratio (CAR), such as:

• Staged migration, which assumes a sharp deterioration in asset quality
• Sectoral sensitivity, requiring additional provisioning for high-risk sectors
• Insider credit treatment, where all insider-related exposures are classified as fully defaulted

Adeleke noted that the framework aligns with Sections 13 and 63 of the Banks and Other Financial Institutions Act (BOFIA) 2020, reinforcing the legal backing of the directive.

He further stressed that a large capital base alone does not guarantee stability if underlying assets are weak. According to him, the CBN aims to ensure that newly raised capital is not quickly eroded by existing non-performing loans.

“The stress test will determine whether banks have sufficient buffers to absorb potential defaults and sustain operations under pressure,” he said.

Adeleke added that the results of the stress test will serve as each bank’s official capital requirement until the next supervisory review cycle.

While recapitalisation focuses on size and solvency, he explained that risk-based capital requirements are designed to enhance stability and risk sensitivity within the banking sector.

With Nigeria targeting a $1 trillion economy by 2030, Adeleke emphasised that banks must maintain strong and resilient balance sheets capable of supporting large-scale economic activities.

DataPro also indicated its readiness to support financial institutions in achieving compliance with the new directive.
