Nigeria rewired its entire banking system in 24 months. The real work starts now

Nigeria’s banking recapitalisation is done. But the Central Bank of Nigeria is not celebrating, it is already moving to ensure the money just raised does not become the next problem.

• Nigeria’s 33 banks raised $2.95 billion (N4.65 trillion) in fresh capital, completing the country’s biggest banking overhaul since 2005.
• The CBN is now redesigning its credit-risk framework to prevent the reckless lending that derailed the last recapitalisation in 2005.
• Some banks like Union Bank and Polaris Bank, missed the March 31 deadline but remain operational under regulatory supervision.
• With Nigeria targeting a $1 trillion economy by 2030, stronger banks are necessary, but economists warn the growth math remains deeply challenging.

"The recapitalisation programme has strengthened the capital base of Nigerian banks, reinforcing the resilience of the financial system and ensuring it is well-positioned to support economic growth and withstand domestic and external shocks," CBN Governor Olayemi Cardoso said.

After two years and approximately $2.95 billion (N4.65 trillion) in fresh capital mobilised across 33 banks, the CBN is quietly redrawing the rules that will govern how that money is managed. The focus has shifted, decisively, from how much was raised to whether it will be handled responsibly.

At the centre of this transition is a comprehensive redesign of the banking sector’s credit-risk framework. While the accumulation is over, discipline is next.

Why history makes this urgent

The concern is grounded in precedent. Following Nigeria’s last major banking overhaul in 2005, the surge in available liquidity triggered a wave of high-risk lending.

Credit controls were loosely enforced, and what followed was a familiar cycle, rapid expansion, then sector-wide distress that required emergency regulatory intervention.

The CBN is determined not to repeat that.

“As recapitalisation progresses, we are redesigning the credit-risk framework to enforce stronger governance, greater transparency, and firmer accountability across the sector. We are determined to break the boom-and-bust cycle that has accompanied past recapitalisation efforts,”Cardoso said.

Without strict oversight, banks can be tempted to channel new funds into aggressive lending, potentially recreating the very vulnerabilities the exercise was designed to eliminate. The CBN’s current posture shows a clear-eyed awareness that recapitalisation alone does not guarantee stability.

What was achieved

The CBN confirmed on April 2 that 33 banks met the revised minimum capital requirements, collectively raising $2.95 billion (N4.65 trillion) over 24 months through public offers, rights issues, private placements, and mergers and acquisitions.

The scale dwarfs Nigeria’s 2004–2005 consolidation exercise, which raised the equivalent of roughly $257 million (N406.4 billion), making the 2026 exercise more than ten times larger.

Capital thresholds were tiered by licence. International banks needed approximately $317 million (N500 billion); national banks around $127 million (N200 billion); regional banks roughly $32 million (N50 billion).

Domestic investors led the charge, contributing 72.55 percent of total capital raised. Foreign investors provided the remaining 27.45 percent, around $810 million (N1.28 trillion), a signal of continued, if measured, international confidence in Nigerian banking.

Union Bank of Nigeria, Polaris Bank, Unity Bank, and Keystone Bank did not fully meet the March 31 deadline, each held back by legacy financial challenges, regulatory complexities, or ongoing ownership restructuring.

The CBN has been firm but reassuring, all banks have remained fully operational, with depositors’ funds secure as outstanding institutions work through a structured transition under supervisory oversight.

The new framework

The CBN’s Credit Risk Management System, already web-enabled, giving banks and stakeholders direct access to borrower data, is now being integrated with internal bank systems to sharpen oversight.

Capital adequacy ratios across the sector now sit above Basel international benchmarks. Cardoso has made clear that meeting the threshold is a floor, not a ceiling.

“We remain vigilant to emerging risks, including cyber threats, credit-concentration pressures, and operational vulnerabilities. These are being addressed through strengthened risk-based supervision and our ongoing transition to Basel III, which will further bolster resilience, improve capital quality, and strengthen liquidity monitoring,” Cardoso said during a forum in Lagos.

Global advisory firm Deloitte, in a recent report on Nigeria’s banking sector, framed the recapitalisation as a necessary response to structural pressure, noting that capital adequacy levels had been eroded by high inflation, currency volatility, and foreign exchange illiquidity.

The upward revision of capital requirements, Deloitte concluded, “will ensure that Nigerian banks have the capacity to take on bigger risks and stay afloat amid both domestic and external shocks.”

The trillion-dollar question

The recapitalisation is explicitly tied to Nigeria’s ambition of becoming a $1 trillion economy, with the banking sector expected to finance the infrastructure, manufacturing, and export-driven businesses that growth at that scale demands.

But the target faces a steep climb. Nigeria grew its GDP by just 3.85 percent in 2025, a fraction of the 17.6 percent annual growth it would need to sustain through 2030 to reach $1 trillion.

"Sustainable economic growth is unattainable without a resilient financial system. This recapitalisation ensures Nigerian banks can fund the scale of transactions needed to drive a $1 trillion economy!" Cardoso said.

The World Bank has bluntly noted that the economy would need to expand roughly five times faster than its recent pace to hit that mark.

The broader environment, though, is more stable than it has been in years. External reserves are near a 13-year high, and inflation has fallen sharply from 34.8 percent in late 2024 to around 15 percent.

With more than 60 percent of Nigeria’s population under 25 and over 160 million active internet subscriptions, newly capitalised banks have a significant and largely untapped opportunity in digital and mobile-first financial services, particularly for small businesses.

Stronger banks create the conditions for growth. They do not guarantee it.

What Nigeria’s banking sector has accomplished in 24 months is genuinely significant, the largest capital mobilisation in its history, completed on schedule, without disrupting daily banking services for millions of customers.

But the real test comes now. The CBN’s pivot toward credit discipline, stress testing, and tighter governance signals it is not taking the achievement for granted.

Resilience, the regulator has made clear, is no longer just about how much capital a bank holds. It is about how that capital behaves when the pressure arrives.
