African banks have crossed a major milestone, with industry revenues now exceeding $100 billion for the first time, a sign of the sector’s growing weight in the global financial system.
- African banking revenues have crossed $100 billion for the first time, signalling the sector’s growing economic weight.
- Banks are outperforming global peers on profitability, with returns well above the global average.
- However, growth remains concentrated in a few key markets and is partly masked by currency depreciation.
- As favourable conditions fade, sustaining momentum will depend on efficiency, diversification, and managing FX risks.
But beneath the headline figure lies a more complex reality: growth is strong, profitability is high, yet much of the momentum is uneven, concentrated, and partly eroded by currency swings.
A new report by McKinsey & Company shows that Africa’s banking sector generated about $99 billion in revenue in 2024 and is estimated to have reached roughly $107 billion in 2025.

A milestone with a concentration problem
The milestone shows how rapidly banking has expanded across the continent, driven by rising financial inclusion, digital adoption, and a fast-growing population.
But the gains are heavily concentrated.
Just five markets, South Africa, Nigeria, Egypt, Morocco and Kenya, account for around 70 per cent of total revenues.
South Africa alone generated about $26.4 billion in 2024, more than a quarter of the continent’s banking income, highlighting how much of Africa’s financial strength is anchored in a handful of economies.
For global investors, that concentration presents both an opportunity and a risk: scale exists, but it is not broadly distributed.
Profits are beating the world
By one key measure, African banks are outperforming most of their global peers.
Returns on equity stood at 19 per cent in 2024 and are expected to moderate slightly to 17 per cent in 2025, still far above the global average of about 10 per cent.
These strong returns have been driven by high interest rates, loan repricing, and a surge in trading and foreign-exchange income.
However, the report suggests this profitability may not be entirely structural. Cost efficiency has not improved significantly, with expense levels rising broadly in line with global trends.
In simple terms: banks are earning more, but not necessarily becoming more efficient.
The hidden gap: fast growth that doesn’t fully show
One of the most striking findings is the disconnect between how fast African banks are growing and how that growth appears on paper.
On a constant-currency basis, revenues expanded at 17 per cent annually between 2020 and 2024, more than double the global average.
But in US dollar terms, growth slowed to about 5.2 per cent a year, as currency depreciation across several markets eroded headline gains.
That gap matters. It shapes how international investors, lenders, and partners assess the true size and performance of the sector.
Even as dollar growth picked up to around 7 per cent in 2025, exchange-rate volatility remains one of the biggest constraints on Africa’s financial story.
What will drive the next phase
Lending remains the backbone of the industry, generating just over $30 billion in revenues in 2024 and accounting for about 30 per cent of the total.
It is expected to remain the largest revenue pool, potentially reaching about $52 billion by 2030.
At the same time, small and medium-sized businesses are emerging as the fastest-growing segment, reflecting a structural shift as more African firms seek formal financing.
Digital banking and payments have also expanded rapidly, driven by mobile technology and a young, urbanising population, trends that continue to differentiate Africa from more mature banking markets.
From momentum to durability
The bigger question now is whether the sector can sustain its momentum.
Much of the recent performance has been supported by favourable conditions, particularly high interest rates and foreign-exchange gains, that may not persist.
As those tailwinds fade, banks will need to rely more on structural strengths: diversified funding, stronger risk management, and the ability to convert local earnings into stable, hard-currency value.
The report argues that African banking is no longer just a story of promise, but of proven performance and resilience.
The next chapter, however, will determine whether that performance can translate into durable, long-term growth in an increasingly volatile global economy.
