South African banks outmuscle Nigerian rivals in Nairobi

As Nigerian banks deepen their push into Kenya and South African lenders tighten their grip, Nairobi is fast consolidating its position as the financial crossroads linking West, Southern and East Africa.

The contest pits Africa’s two largest banking hubs against each other, with lenders seeking to offset slowing growth, currency pressures and rising risk in their home markets. An analysis of market share, assets, deposits and capital positions – alongside a flurry of acquisition activity – reveals starkly different strategies.

South African banks are entrenched incumbents with scale, capital and system-wide influence, while Nigerian lenders are leaner, later entrants waging on long-term regional expansion.

South Africa’s incumbency is an advantage over Nigeria. Three of its ‘Big Four’ banks collectively control more than 20% of Kenya’s banking market, anchored by large balance sheets and robust capital buffers.

NCBA, which is set to be acquired by Nedbank in an estimated $855m deal, leads with an 8.3% market share, assets of KSh665.3bn ($5.2bn) and customer deposits of KSh488bn. Once completed, the transaction will create Kenya’s largest foreign-linked lender.

Absa Kenya follows with a 6.6% share, while Standard Bank’s Stanbic, previously linked to a potential NCBA bid before Nedbank’s surprise move, holds 5.7%. Both Absa and Stanbic report assets exceeding KSh450bn.

Nigerian banks, by contrast, remain marginal by market share. Even after Access Bank’s high-profile acquisition of National Bank of Kenya (NBK), the combined entity controls just 1.8% of the market. GT Bank, UBA and Zenith-linked Paramount Bank each hold less than 1% individually.

Scale versus speed

The divergence reflects fundamentally different playbooks.

Johannesburg-based lenders entered Kenya earlier, building scale through acquisitions and organic expansion. Years of investment have embedded them in retail, SME and corporate banking, leaving their Kenyan units profitable, well-capitalised and deeply integrated into the financial system.

Nigerian banks are still gaining traction. Most operate with relatively small balance sheets – assets ranging from KSh15bn to KSh35bn – while Access Bank continues to restructure its Kenyan operations following the NBK acquisition, which previously weighed on capital levels.

Yet scale is not the sole marker of ambition. Nigerian lenders have been aggressively raising capital at home to meet tougher regulatory thresholds and bankroll offshore expansion, giving them flexibility as they pursue new growth corridors.

Why Kenya matters

Kenya is increasingly viewed as the gateway to East Africa, offering access to key trade routes, a sophisticated financial ecosystem and regulatory credibility. Domestic giants like Equity Group, KCB Group and Co-operative Bank still dominate in assets and profitability, with growing regional footprints.

Foreign banks hold smaller market shares but punch above their weight in corporate and trade finance. For Nigerian banks, Kenya represents the missing eastern link in their pan-African networks spanning West and Central Africa. For South African lenders, it is a defensive anchor and losing ground would weaken their continental influence.

This dynamic explains Nigeria’s pivot toward acquisitions over greenfield expansion. Access Bank’s takeover of NBK delivered instant scale, government relationships and a nationwide branch network that would have taken years to build organically.

Strategies sharpen

South African banks are increasingly prioritising depth over breadth. Nedbank-linked NCBA, Absa and Stanbic are expanding digital lending, trade finance and corporate banking, leveraging strong capital bases to finance infrastructure projects and multinational clients across East Africa.

With deposits exceeding KSh300bn at Absa and Stanbic, the lenders enjoy pricing power and resilience against regulatory shocks, supported by some of the lowest non-performing loan ratios in the market.

Nigerian banks, meanwhile, are playing the long game. Their focus is on corporate banking, diaspora flows, trade finance and Pan-African clients – particularly Nigerian firms expanding eastwards. GT Bank and UBA have leaned into digital platforms, lean branch models and cross-border capabilities to operate efficiently despite smaller deposit bases.

Access Bank’s approach signals a shift toward scale, underscoring that Nigerian lenders are no longer content with niche roles in Kenya’s banking landscape. (The Africa Report)
