Inside Africa’s Growing Appetite for Digital-Only Banks

LAGOS — A new generation of banks operating without a single physical branch has taken root across Africa’s largest economies, drawing millions of customers who had previously gone without a formal bank account or had grown frustrated with the cost and friction of traditional lenders. Digital-only banks — often licensed as microfinance banks or under newly created fintech charters — have expanded fastest in Nigeria, Kenya, Egypt and South Africa, markets that combine large urban populations, high smartphone penetration and persistent gaps left by incumbent financial institutions that built their infrastructure and pricing models around a narrower, wealthier customer base. The rise of these institutions has reshaped competitive dynamics in African banking, forced legacy lenders to accelerate their own digital transformation, and raised new questions about what sustainable, profitable financial inclusion at scale actually looks like.

The appeal to customers has centered on three factors: lower fees, faster onboarding and a user experience built around mobile apps rather than paper forms and fluorescent-lit branches. Opening an account with a digital bank typically takes minutes, requiring little more than a national identification document and a selfie processed through automated verification software, compared with the multi-day, document-heavy process still common at many legacy institutions. Account maintenance fees, a persistent complaint among bank customers across the continent, are frequently waived entirely or set well below what traditional banks charge, an approach that has proven effective at attracting first-time account holders who had previously balked at paying fees on an account they expected to use infrequently.

Nigeria has emerged as the continent’s most competitive market for digital banking, a status shaped partly by the country’s sheer population size — the largest on the continent — and partly by a regulatory environment that, while complex, has been relatively open to new entrants compared with many African peers. Digital-first lenders built initial customer bases in the millions before expanding into adjacent products including savings accounts with above-average interest rates, small-ticket personal loans and bill payment services that had previously required visits to bank branches or payment agents. Central bank data has shown digital channels accounting for a rising share of total transaction volume in the country’s banking system, even as cash remains dominant in everyday commerce outside major cities. The country’s five largest digital banks have collectively enrolled tens of millions of customers, a figure that would have been implausible for a bank without branch infrastructure in any previous era of Nigerian financial history.

Kenya’s experience has followed a different path, shaped by the pre-existing dominance of mobile money as the primary entry point to formal finance for most of the population. M-Pesa’s penetration is so deep that most Kenyans who use financial services at all already have access to a mobile money wallet, meaning digital banks operating in the country have generally positioned themselves as complements to mobile wallets rather than replacements. They have done so primarily by offering higher interest rates on deposits, more sophisticated savings products and credit facilities not available directly through mobile money platforms. The competitive dynamic has also pushed incumbent commercial banks to accelerate their own digital offerings aggressively; several of Kenya’s largest traditional lenders now route the majority of customer transactions through mobile and online channels rather than branches, a transformation driven as much by the threat from digital challengers as by any proactive strategic vision.

South Africa’s market presents yet another variant, where digital-only challengers have entered a banking sector already characterized by relatively high formal banking penetration compared with most sub-Saharan African peers, competing less on basic access and more on cost transparency and customer experience. Several digital banks launched in the country by technology and retail conglomerates have undercut incumbent fee structures sharply, prompting a pricing response that has benefited consumers even among those who remain with traditional banks. South Africa’s mature credit bureau infrastructure and relatively strong consumer protection legal framework have also allowed digital banks there to build credit products more quickly than in markets where such infrastructure is thinner.

Egypt presents a different growth trajectory again, shaped by a central bank push toward financial inclusion targets tied to the country’s broader economic reform program and a population of over 100 million of whom a substantial share historically lacked formal bank accounts. Digital banking licenses issued in recent years have drawn applications from telecom operators, e-payment companies and diversified banking groups alike, reflecting expectations that a large, young, increasingly smartphone-connected population represents significant untapped demand for accessible financial services. Currency volatility and periodic capital controls have complicated international investor appetite for the sector, even as domestic usage of digital payment and savings apps has continued to climb through each successive economic adjustment cycle.

Francophone West Africa has lagged the continent’s anglophone digital banking leaders, a gap attributed in part to the region’s currency union structure under the CFA franc, which centralizes certain monetary and regulatory functions through the regional central bank, the BCEAO, in ways that can slow country-specific fintech licensing relative to more decentralized regulatory environments. Mobile money nonetheless remains deeply entrenched across the region, with operators including Orange Money and the venture-backed challenger Wave having built substantial customer bases in Senegal, Côte d’Ivoire, Burkina Faso and Mali by competing aggressively on fees — Wave, in particular, built its initial growth on a model of near-zero transaction fees that disrupted established pricing norms and demonstrated that the traditional mobile money fee structure was not a structural necessity but a reflection of limited competition.

Profitability has proven more elusive than customer acquisition across the sector. Several digital banks have built large user bases quickly by offering free or near-free basic accounts, only to face the harder task of converting those users into profitable relationships through lending, premium savings products or transaction-based revenue. Capital-intensive credit underwriting, in particular, has tested business models built around speed and minimal documentation. Default rates on unsecured digital loans have in some markets run well above those associated with traditional collateral-backed lending, forcing several providers to tighten credit scoring criteria, reduce maximum loan amounts or temporarily scale back lending altogether while rebuilding risk models with more extensive behavioral data.

Funding conditions have tightened alongside a broader pullback in venture capital available to African fintech companies following a period of rapid valuation growth during the global low-interest-rate environment of the early 2020s. Investors that once prioritized user growth above all other metrics have shifted toward scrutinizing unit economics and the credible path to profitability, pushing digital banks to demonstrate that their business models can sustain themselves without perpetual external subsidies. Several smaller digital banking ventures have shut down or been absorbed by larger competitors as a result, a consolidation trend analysts expect to continue as the gap between well-capitalized digital banks with clear revenue models and subscale challengers without them continues to widen.

Talent and technical infrastructure costs represent structural challenges that often receive less attention than customer growth metrics but matter enormously for the sector’s long-term economics. Building and maintaining secure, high-availability banking infrastructure requires specialized engineering and risk management talent that remains in short supply across the continent’s major tech hubs, pushing salary costs upward. Cloud infrastructure, often billed in US dollars, has become a more significant cost line for digital banks operating in markets where local currencies have depreciated meaningfully, squeezing margins for companies that had built financial projections under more stable exchange rate assumptions.

Looking across the sector as a whole, the central strategic challenge facing African digital banks is no longer primarily one of customer acquisition — penetration in major urban markets is already substantial and growing — but rather of depth. Converting a customer who opened a free account and uses it occasionally for bill payments into a customer with a savings plan, a personal loan, a health insurance product and consistent engagement represents a fundamentally different operational challenge from the initial sign-up process. The institutions that resolve this challenge successfully, by building genuinely trusted, multi-product financial relationships with customers who have historically had reason to distrust formal financial institutions, will be the ones that define what African digital banking looks like at maturity. How quickly the sector reaches that maturity, and how many of today’s players survive to participate in it, will depend heavily on the regulatory frameworks, macroeconomic conditions and infrastructure investments that shape the competitive landscape in each of the continent’s diverse markets over the next several years.
