Why Mergers Are Increasing in Nigeria’s Banking Sector

Let me tell you about a transformation reshaping Nigerian finance.

Across the country, banks are merging, raising capital, and navigating regulatory pressure at a pace not seen since the landmark consolidation of 2004. The question driving every boardroom conversation is the same: why are mergers increasing in Nigeria’s banking sector?

The answer lies in a regulatory directive from the Central Bank of Nigeria that has fundamentally reshaped the industry.

If you need professional support, our financial services M&A and regulatory advisory can help you navigate this changing landscape.

What a bank merger actually means

Before examining why mergers are happening, let us establish what a bank merger actually is.

According to the University of Oklahoma, “A merger is a business deal where two existing, independent companies combine to form a new, singular legal entity. Mergers are voluntary. Typically, both companies are of a similar size and scope and both stand to gain from the transaction.”

In the Nigerian banking context, this takes on particular significance. When two Nigerian banks merge, they are combining capital bases, loan books, deposit liabilities, technology infrastructure, and regulatory obligations, all while navigating strict CBN oversight.

The CBN recapitalisation directive: the primary driver

The most direct cause of the current merger wave is a landmark regulatory directive from the CBN.

In March 2024, CBN Governor Olayemi Cardoso issued a circular announcing sweeping new minimum capital requirements. The new thresholds are dramatic.

Commercial banks with international licences must hold a minimum share capital of ₦500 billion, up from ₦50 billion, a tenfold increase. National commercial banks must hold ₦200 billion. Regional commercial banks must meet ₦50 billion.

Banks were given a compliance window from April 1, 2024 to March 31, 2026, with no extension granted. To meet these thresholds, banks could raise fresh equity or pursue mergers, acquisitions, or licence downgrades.

For many smaller and mid-tier banks, the independent capital-raising route was simply not feasible. For these institutions, mergers were not a first choice. They were the only viable path to survival.

This recapitalisation exercise is the most significant overhaul of Nigeria’s banking sector since the 2004 consolidation, which reduced the number of banks from 89 to just 25.

Why the CBN is demanding more capital

The recapitalisation directive reflects specific concerns about Nigeria’s economic trajectory.

Supporting the $1 trillion economy ambition.

The government has set an ambitious target of building a $1 trillion economy by 2030. Achieving this requires a banking sector capable of financing large-scale infrastructure and industrial projects. Banks with thin capital bases cannot extend the credit that a trillion-dollar economy demands.

Absorbing macroeconomic shocks.

Nigeria’s economy has experienced significant stress. Fuel subsidy removal. Naira devaluation. High inflation. Geopolitical pressures. Banks that cannot absorb these shocks transmit their distress to the wider economy through credit contraction and deposit freezes.

Strengthening the banking system after FATF greylisting.

Nigeria’s removal from the Financial Action Task Force (FATF) greylist created an opportunity to rebuild international credibility. Stronger, better-capitalised banks with improved anti-money laundering systems are central to demonstrating financial system integrity.

Expanding credit to the real economy.

A more capitalised banking sector means more lending capacity for SMEs, manufacturers, farmers, exporters, and consumers.

The merger deals: what is actually happening

The recapitalisation policy has already produced a wave of concrete merger activity.

Union Bank of Nigeria and Titan Trust Bank.

This was the first significant merger of the recapitalisation era, completed ahead of the deadline. Union Bank, Nigeria’s second-oldest lender, combined with Titan Trust Bank. The CBN approved the transaction, establishing it as a template for other consolidation deals.

Providus Bank and Unity Bank.

One of the most closely watched consolidation moves, this merger was concluded on March 25, 2026, just days before the regulatory deadline. The combined entity would become Nigeria’s ninth-largest lender by assets. Unity Bank secured a ₦700 billion financial accommodation from the CBN to facilitate the transaction.

Polaris Bank and Keystone Bank.

Both banks were engaged in discussions about a potential merger throughout 2025. Polaris Bank’s capital base of approximately ₦50.43 billion required it to raise an additional ₦150 billion to meet the national bank threshold.

The tier-1 banks: a different strategy.

For Nigeria’s largest banks, the recapitalisation presented an opportunity rather than a threat. GTCO raised ₦209 billion. Zenith Bank raised ₦350.4 billion. Access Holdings launched a ₦351 billion rights issue and completed four cross-border acquisitions in 2025. These institutions used the recapitalisation window not merely to comply but to accelerate regional expansion.

Lessons from the 2004 consolidation

Nigeria has been through a major banking consolidation before. Looking back provides critical context.

In 2004, then-CBN Governor Charles Soludo initiated a ₦25 billion minimum capital base requirement. Banks were given 18 months to raise their capital base from ₦2 billion to ₦25 billion. Of 89 banks operating at the time, only 25 survived through mergers, acquisitions, and fresh capital injections.

The results, while painful in the short term, were largely positive. The surviving banks were significantly larger, better governed, and more capable of financing large transactions. Nigeria’s banking sector entered a period of rapid growth and gained genuine regional significance.

The current recapitalisation is not identical to 2004. The thresholds are far higher. The macroeconomic context is more complex. But the underlying logic is the same: fewer, stronger banks are better for the economy than many weak ones.

By late 2025, at least 32 banks had already met the new capital requirements, collectively raising over ₦4 trillion, with the total crossing ₦4.6 trillion by the final stretch of the deadline.

The final days of the recapitalisation deadline

The situation evolved at extraordinary speed in the final weeks.

March 31, 2026: the deadline arrived.

The CBN’s recapitalisation deadline closed on March 31, 2026, with no extension granted. The banking sector entered a period of anticipation as institutions awaited regulatory direction.

Over ₦4.6 trillion raised across the sector.

Banks collectively raised over ₦4.6 trillion through public offers, rights issues, private placements, and merger transactions. This represents the largest capital raise in Nigeria’s banking history.

32 banks confirmed compliant.

At least 32 banks confirmed compliance with the new capital thresholds. Compliant institutions included Globus Bank, Premium Trust Bank, Optimus Bank, Titan Trust Bank, Signature Bank, Parallex Bank, SunTrust Bank, Jaiz Bank, Lotus Bank, TAJ Bank, and The Alternative Bank, alongside all major tier-1 banks.

Banks still under review.

Banks including Keystone Bank, Polaris Bank, Standard Chartered Bank Nigeria, and Citibank Nigeria were still weighing options as the deadline arrived.

CBN tightens prudential and AML regulations.

Beyond capital adequacy, the CBN will further tighten prudential, risk management, and anti-money laundering regulations, raising compliance and operational costs.

Foreign investor appetite increases.

The recapitalisation has rekindled foreign investor interest. Banking stocks rallied significantly in 2025, with GTCO, Zenith, UBA, and others lifting combined market capitalisation to ₦16.14 trillion, an 86.8 percent increase.

Africa’s banks spent over $537 million on acquisitions in 2025.

Nigeria’s recapitalisation push was part of a broader pan-African banking consolidation trend. Africa’s largest lenders collectively spent over $537 million on acquisitions in 2025.

What mergers mean for businesses, depositors, and the economy

The wave of bank mergers has direct and significant implications.

For businesses: more lending capacity.

A more capitalised banking sector translates directly into greater credit availability. Larger banks can extend bigger loans and finance infrastructure and industrial projects that smaller banks could not touch.

For depositors: greater stability.

The fundamental purpose of recapitalisation is to make Nigerian banks more resilient. Depositors in well-capitalised banks are better protected from shocks that have caused bank failures in Nigeria’s past.

For the digital economy: better infrastructure.

Mergers allow banks to consolidate and upgrade their technology infrastructure. Combined institutions can invest more in digital banking platforms and cybersecurity systems.

For investors: a more attractive sector.

A banking sector defined by fewer, stronger, better-governed institutions is more attractive to both domestic and international investors. The recapitalisation has already demonstrated this with NGX banking stock values rising dramatically.

For competition: risks of reduced choice.

Consolidation is not without risks. Fewer banks mean less competitive pressure, which can lead to higher fees and reduced innovation. Regulators will need to monitor market concentration carefully.

Where to go from here

The recapitalisation exercise has set the stage for a fundamentally different Nigerian banking sector. The banks that emerge will be larger, better capitalised, and better positioned to support Nigeria’s economic ambitions.

The strategic question for surviving Nigerian banks is not just how to meet capital thresholds. It is how to deploy that capital effectively, expand across Africa, and deliver the financial services that Nigeria’s growing, digitally connected population demands.
