Financial Inclusion in the Global South
Read 1 of 3
How mobile money, digital banking, and fintech are bringing billions of unbanked people into the financial system.
As recently as 2011, 2.5 billion adults worldwide had no bank account. They saved by hiding cash under mattresses, borrowed from moneylenders at extortionate rates, and sent remittances through informal and expensive channels. By 2022, the number of unbanked adults had fallen to roughly 1.4 billion -- a dramatic improvement driven largely by mobile money and digital financial services.
Financial exclusion is not just an inconvenience; it is a development trap. Without a bank account, people cannot safely save, access credit for productive investment, insure against risk, or receive government transfers efficiently. Women, rural populations, and the poorest households are disproportionately excluded. In sub-Saharan Africa, only 55% of adults have a bank or mobile money account, compared to over 95% in high-income countries.
The most successful financial inclusion innovations have come not from traditional banks but from mobile network operators and fintech startups. M-Pesa in Kenya, bKash in Bangladesh, GCash in the Philippines, and Pix in Brazil have each brought tens of millions of people into the digital financial system. India's 'India Stack' -- combining biometric identity (Aadhaar), a universal payments interface (UPI), and digital consent -- has enabled over 10 billion digital transactions per month.
These innovations succeed because they meet people where they are: on their mobile phones, in their languages, with interfaces simple enough for users with limited literacy. They also benefit from light-touch regulation that allows experimentation. Kenya's central bank let M-Pesa operate under telecom rather than banking regulation initially, avoiding the heavy compliance costs that would have killed the product.
