SEC-registered credit rating agency, DataPro Limited has said post-capitalisation ratings of deposit money banks DMBs would depend on the resilience and quality of capital, not merely its size. 

DataPro in its April 2026 Rating Brief titled Nigerian Banks: Ratings Post Consolidation signed by the Founder, Abimbola Adeseyoju and sent to Vanguard, said “Banks must demonstrate effective stress testing, portfolio analysis and capital shortfall remediation.”

According to DataPro, “Institutions with robust risk management frameworks are more likely to get stable or improved credit ratings, while weaker banks may face rating pressure despite meeting capital thresholds.

While acknowledging that the recapitalisation of Nigerian banks, coupled with the Central Bank of Nigeria’s (CBN) Risk-Based Capital directive, has significant implications for credit ratings across the sector, DataPro insisted that while many banks have met the minimum paid-up capital thresholds, ratings are increasingly determined by the quality, resilience, and risk-absorbing capacity of that capital, rather than its nominal size.

Elaborating, it said, “Although banks have reached the paid-up capital thresholds N500B, N200B, or N50B, depending on size), meeting these amounts alone is insufficient. They must demonstrate through stress testing that their capital is truly loss-absorbing and sufficient to maintain minimum Capital Adequacy Ratios (CAR) under simulated portfolio deterioration. This distinction is critical for credit rating agencies in assessing post-capitalisation ratings.”

“Credit rating agencies will now focus on how effectively banks manage and deploy their capital. Large paid-up capital alone does not guarantee stability if underlying assets are deteriorating,” Adeseyoju said. 

“Stress testing, mandated under the Risk-Based Capital framework, evaluates whether capital can absorb potential losses while maintaining regulatory CAR levels.

“Banks demonstrating strong portfolio management, proactive risk mitigation, and rigorous stress-testing practices are likely to maintain or improve ratings. Conversely, banks that fail to align capital with actual risk exposures may face rating pressure, even if they meet recapitalisation requirements.

He added: “The Central Bank of Nigeria’s Risk-Based Capital directive requires banks to conduct rigorous stress testing to evaluate the resilience of their capital. Rating agencies consider these stress tests a key determinant of post-capitalisation ratings.

, as they reveal whether a bank’s capital is genuinely loss-absorbing and sufficient to withstand portfolio deterioration.”

“Banks that effectively execute portfolio stress simulations, risk migration analysis, and capital shortfall assessments demonstrate that their capital can absorb potential losses without breaching minimum Capital Adequacy Ratios (CAR). Such banks are more likely to maintain or improve their credit ratings.

“Conversely, banks that fail to apply the prescribed stress testing methodology or that cannot show their capital’s resilience may face rating pressure, even if they meet the minimum paid-up capital requirements. Stress testing under the RBC framework thus acts as a critical filter, linking recapitalisation to actual financial stability and rating outcomes,” DataPro concluded.
