A farmer in rural Kenya can receive payment for her crops, save a portion in a digital account, pay her children’s school fees, and purchase crop insurance, all from a phone that costs $25 and has no internet browser. M-Pesa and the mobile money ecosystem built on top of it made this possible. Before mobile money, the nearest bank branch was a four-hour bus ride away, and the minimum deposit to open an account exceeded a month’s income. The World Bank estimates that 1.4 billion adults globally remain unbanked, but that number has fallen by 500 million since 2011, with digital banking responsible for the majority of new account openings. The neobanking market that powers much of this expansion reached $210.16 billion in 2025, according to Fortune Business Insights.
The Geography of Financial Exclusion
Financial exclusion is not distributed randomly. It concentrates in specific regions and demographics. Sub-Saharan Africa has the lowest bank account penetration at approximately 55% of adults. South Asia follows at around 68%. Within these regions, women, rural populations, and informal-sector workers are disproportionately excluded.
The barriers are structural, not behavioural. People without bank accounts generally want them. The obstacles are distance (no branch within reasonable travel distance), cost (minimum balance requirements, monthly fees, transaction charges), documentation (formal identity documents required but not universally held), and trust (negative experiences with formal financial institutions or preference for community-based alternatives).
The Boston Consulting Group projects fintech revenues will reach $1.5 trillion by 2030, with embedded finance and digital lending accounting for the largest share of projected growth.
According to CB Insights’ 2024 fintech report, global fintech funding declined 40 percent between 2022 and 2024, pushing the sector toward consolidation and a sharper focus on profitability over growth at all costs.
Digital banking addresses each of these barriers directly. Distance becomes irrelevant when banking runs on a mobile phone. Costs drop when there are no branches to maintain. Documentation requirements simplify when digital identity verification replaces paper-based processes. Trust builds incrementally through small, successful transactions.
Mobile Money: The First Wave of Digital Financial Access
M-Pesa launched in Kenya in 2007 and demonstrated that mobile phones could deliver financial services to populations that banks had failed to reach. The service processed person-to-person transfers through a network of local agents (shops, kiosks, petrol stations) where customers could deposit and withdraw cash. No bank account required. No internet required. The service ran on basic SMS-capable phones.
By 2024, mobile money services across Africa processed over $1 trillion in annual transaction value. The model expanded beyond Kenya to Tanzania, Ghana, Uganda, and dozens of other markets. Similar services launched in South Asia (bKash in Bangladesh, JazzCash in Pakistan) and Southeast Asia (GCash in the Philippines, Dana in Indonesia).
Mobile money proved that demand for financial services among unbanked populations was enormous. The limitation was product range. Mobile money handles payments and basic savings, but not lending, insurance, or investment products. The next wave of digital banking is layering these products on top of the payment infrastructure that mobile money established.
Neobanks and Financial Inclusion
Neobanks approach financial inclusion differently from mobile money. Where mobile money started with basic payments and worked upward, neobanks start with a full banking product (current account, card, savings) and price it at zero or near-zero to remove the cost barrier.
Nubank in Brazil is the largest example. Before Nubank launched in 2013, Brazil’s banking market was dominated by five large banks that charged some of the highest fees in the world. Monthly account maintenance fees of 25 to 40 reais (approximately $5 to $8) were standard. For a worker earning minimum wage of 1,320 reais per month, those fees consumed 2% to 3% of income. Nubank offered a no-fee credit card, then a no-fee digital account, and attracted over 100 million customers, including millions who had never held a bank account.
The global neobanking market is growing at 49.30% annually, per Fortune Business Insights, toward $7.66 trillion by 2034. A significant portion of that growth comes from markets where neobanks are serving previously excluded populations for the first time.
The Technology That Makes Inclusion Economically Viable
Serving low-income customers profitably requires a cost structure that traditional banks cannot achieve. When the average account balance is $50 and the average transaction is $3, the bank’s cost per account must be close to zero. Branch-based banking, where the cost of maintaining a single branch exceeds $2 million per year, cannot serve this segment without subsidies.
Cloud-native banking infrastructure changes the economics. The banking-as-a-service market reached $18.6 billion in 2024, according to Global Market Insights, with cloud deployment accounting for 67% of the market. Cloud infrastructure reduces the marginal cost of each additional account to near zero, making it economically viable to serve customers whose balances would never cover the cost of a branch visit.
API-based architecture reduces the cost of each banking function further. Identity verification through an API call costs a fraction of in-person document review. Payment processing through a digital rail costs a fraction of a cash-handling infrastructure. Banks globally process over 2 billion API calls daily, handling $676 billion in transaction value, per Coinlaw. Each of those API calls represents a banking function delivered at digital cost rather than physical cost.
Remaining Gaps in Digital Financial Accessibility
Digital banking has made enormous progress on financial inclusion, but significant gaps remain.
Digital literacy is the first. A mobile banking app is useless to someone who cannot navigate a smartphone interface. In many developing markets, particularly among older rural populations, digital literacy is low enough that mobile money agents (who assist customers with transactions in person) remain essential intermediaries.
Connectivity is the second. Mobile banking requires a mobile network. In rural areas of Sub-Saharan Africa, South Asia, and Latin America, network coverage is unreliable or absent. Offline-capable banking solutions exist but are limited in functionality.
Identity documentation is the third. Digital identity verification requires a government-issued ID. The World Bank estimates that approximately 850 million people globally lack any form of official identification. Without it, they cannot pass the know-your-customer checks that banking regulations require, even at a neobank.
Credit access is the fourth. Opening an account is the first step, but access to credit, the financial product with the greatest impact on economic mobility, requires data that newly banked customers do not yet have. Alternative credit scoring models that use mobile phone usage patterns, utility payments, and transaction history are emerging but are not yet as accurate or widely deployed as traditional credit bureau models.
Digital banking has brought hundreds of millions of people into the formal financial system for the first time. The remaining 1.4 billion will be harder to reach, because the barriers they face, lack of identity documents, lack of connectivity, lack of digital literacy, are problems that technology alone cannot solve. They require coordination between governments, telecoms, technology companies, and financial institutions that is progressing, but slowly.
