Nigeria's banks are racing to meet a Central Bank of Nigeria (CBN) deadline of April 30, 2026, to submit Board-approved Risk-Based Capital (RBC) stress test reports. The directive, issued March 6, 2026, requires lenders to evaluate how their capital would withstand adverse credit conditions, using a 12-month simulated asset migration model. This follows the March 31, 2026 conclusion of the sector's recapitalisation, which saw 33 banks meet revised minimum capital thresholds. The new framework, signed by Olubukola A. Akinwunmi and Hakama Sidi Ali, strengthens the risk-based capital adequacy regime under BOFIA 2020 and updates 2019 stress testing guidelines. It extends scrutiny to all on- and off-balance sheet exposures and mandates regular testing across defined scenarios.
The CBN says the policy safeguards gains from recapitalisation and reinforces governance, risk management and sector resilience. Analysts at DataPro describe the RBC test as the "ultimate filter," noting that large paid-up capital does not ensure stability if asset quality deteriorates. Banks must maintain capital buffers above minimum Capital Adequacy Ratios of 10 percent for regional and national banks and 15 percent for international lenders. Where gaps are found, institutions must raise additional capital under the "Higher of 50/100" rule—covering either 100 percent of their own stressed shortfall or 50 percent of the CBN's computed gap. They will have 18 months to comply, with non-compliant banks facing tighter oversight, including a follow-up test after six months. The CBN has also set a 10 percent provisioning floor for high-risk sectors like agriculture and manufacturing.
The real test of Nigeria's banking strength isn't the capital raised on paper but how it holds up when loans go bad. With 33 banks having met the cash threshold but now facing the CBN's stress gauntlet, the focus shifts from balance sheet size to survival capacity. DataPro's "Higher of 50/100" rule means some lenders may soon be forced to dig deeper—proving that regulatory muscle is finally matching financial ambition. For Nigerian depositors, this could mean fewer surprises when the next economic shock hits.
