CBN’s post-recapitalisation supervisory framework sets new standard for Nigerian banking

The Central Bank of Nigeria, on Wednesday, announced the conclusion of its 24-month banking sector recapitalisation programme, confirming that Nigerian banks raised ₦4.65 trillion in new capital since the exercise launched in March 2024.

For market participants, the more consequential development is the supervisory framework the CBN has put in place to govern and stress-test that capital on an ongoing basis.

The apex bank confirmed that its risk-based capital adequacy framework has been materially strengthened, with Nigerian banks now required to conduct regular stress testing across defined scenarios and maintain appropriate capital buffers on an ongoing basis. Read alongside the other supervisory commitments embedded in the announcement, periodic review of prudential guidelines, continued strengthening of the supervisory intervention framework, and the completion of an orderly exit from regulatory forbearance, the picture that emerges is of a central bank that views recapitalisation not as a destination but as infrastructure.

The requirement for regular stress testing across defined scenarios represents a substantive upgrade to the supervisory toolkit available to the CBN. In practice, it means that Nigerian banks must now model their capital adequacy against a range of adverse economic conditions, currency depreciation scenarios, commodity price shocks, credit deterioration events, and other systemic stresses, and demonstrate that their capital buffers are sufficient to absorb them.

This is precisely the standard applied to financial institutions in the UK, the European Union and the United States, where annual stress tests conducted by the Bank of England, the European Banking Authority and the US Federal Reserve have become central instruments of macroprudential oversight. The embedding of comparable requirements in Nigeria’s supervisory framework marks a meaningful convergence with international best practice.

For sophisticated investors, particularly the international market participants who contributed 27.45% of the ₦4.65 trillion capital raised, the practical implication is significant. It means that the capital positions reported by Nigerian banks going forward will be tested positions, not merely declared ones. The credibility of those figures, and the confidence investors can place in them, increases accordingly.
Wednesday’s announcement confirmed that the recapitalisation was implemented in parallel with an orderly exit from regulatory forbearance, the supervisory arrangements that had allowed certain institutions to defer recognition of balance sheet risks during periods of economic stress. That exit is now complete.

For financial analysts, this is not a technical footnote. It means that the capital adequacy ratios now reported across the Nigerian banking sector, ratios the CBN confirms exceed international Basel benchmarks, reflect genuine underlying financial positions. Asset quality has improved. Balance sheet transparency has increased. The numbers being reported are the numbers that exist.

Sector capital adequacy ratios above the minimum CAR thresholds of ten percent for regional and national banks and 15 for internationally authorised institutions provide a meaningful buffer against the kinds of shocks that have historically transmitted through banking systems to broader economic activity. The exit from forbearance means those buffers are real.

With 33 banks confirmed fully compliant and all institutions remaining operationally uninterrupted throughout the exercise, attention in the investment community will now shift from capital adequacy to capital deployment. The recapitalisation was designed, in part, to give Nigerian banks the balance sheet capacity to underwrite larger, longer-duration financing, the kind required for infrastructure, manufacturing, and the continental trade finance that Nigeria’s participation in the African Continental Free Trade Area demands.

The CBN has been explicit that the goal of the exercise is not merely to withstand shocks but to actively support economic growth. Governor Olayemi Cardoso, in remarks accompanying the announcement, described the recapitalised system as one now positioned to support economic growth and withstand domestic and external shocks, framing resilience and growth capacity as two aspects of the same structural improvement.
Wednesday’s announcement closes the formal compliance window of the recapitalisation programme. What it opens is a new chapter in Nigerian banking supervision, one defined less by the pursuit of capital targets and more by the active management of a sector that now has the resources and the regulatory framework to do considerably more than it could two years ago.
