Nigerian Banks Face Looming Deadline: Expert Guidance on CBN Stress Test Compliance

DataPro, a leading Nigerian technology-driven rating agency, has issued a timely advisory to banks in the country, urging them to initiate portfolio analysis and establish a baseline data set in anticipation of the Central Bank of Nigeria's (CBN) impending risk-based capital requirement policy.

This directive, announced on March 6, mandates banks to conduct stress tests aimed at identifying vulnerabilities stemming from credit risk exposures. The exercise is slated to take effect on April 1, 2026, immediately following the conclusion of the ongoing banking sector recapitalization exercise.

According to Idris Adeleke, a member of DataPro's rating team and an Enterprise Risk Management (ERM) expert, the CBN's initiative is geared towards bolstering the resilience of the financial sector in support of President Bola Tinubu's $1 trillion economy target. Adeleke emphasized the importance of prompt action, recommending that banks prioritize data gathering and migration of credit exposures to meet the stringent regulatory deadline.

The stress test is designed to evaluate the bank's ability to withstand extreme economic conditions, such as a severe recession or market crash. DataPro's advisory highlights the significance of collaboration across risk, finance, and compliance teams to finalize stress test results on time, with the Board-approved stress testing report required to be submitted to the CBN by April 30, 2026.

The new CBN mandate introduces severe stress assumptions that will directly impact the Capital Adequacy Ratio (CAR), including a 'staged migration' that requires banks to assume a severe deterioration in asset quality across all credit exposures. Other key assumptions include sectoral sensitivity and insider credits, which necessitate additional provisioning floors and specific treatment of director- and insider-related credits.

DataPro's recent webinar, 'Bank Capital Stress Testing: Getting the CBN Directive Right,' provided stakeholders with step-by-step guidance on executing the mandated staged migration, strategies for validating shortfall calculations, and overview of reference models and reporting templates to ensure seamless compliance by the April 30 deadline.

Adeleke noted that the stress test framework aligns with Section 13 and Section 63 of the Banks and Other Financial Institutions Act (BOFIA) 2020, emphasizing the regulator's goal of ensuring that banks possess sufficient capital to manage the risks they undertake. The expert highlighted the distinction between a large capital base and a robust capital base, stressing that the former can be fragile if underlying assets are deteriorating.

The CBN's transition from a fixed capital requirement to a risk-based capital requirement underscores the importance of stress testing in determining a bank's official individual capital requirement. As the banking sector navigates this critical juncture, DataPro's expert guidance serves as a vital resource for banks seeking to comply with the CBN's directive and maintain a strong, resilient financial sector.
