Financial Inclusion as a Determinant of Economic Growth in Selected Lower-Middle-Income African Countries
Using panel regression analysis on secondary data from selected lower-middle-income African countries, this study finds that while financial inclusion indicators like commercial bank branches and deposit accounts have a statistically significant negative impact on real GDP growth, the research concludes that financial inclusion remains a meaningful determinant of economic growth through credit access, savings mobilization, and increased banking penetration.

For decades, economists have operated on a simple, comforting assumption: that if you build more banks and open more savings accounts, a country's economy will naturally grow. The logic seems sound. If people can walk into a branch to get a loan or open an account to save their money, they can invest in businesses, buy homes, and start farms. This flow of money, from savers to borrowers, is supposed to be the engine that drives a nation forward. In many parts of the world, this engine works as expected. But in a specific group of ten lower-middle-income African nations, researchers recently decided to test whether this engine actually turns the wheels of the economy, or if it is simply idling in neutral. They looked at two specific things: the physical presence of bank branches and the number of active savings accounts held by ordinary people. Their goal was to see if these markers of "financial inclusion"—the idea that everyone has access to useful financial services—actually translate into real economic growth.
The researchers, a team from Nigerian and Abuja-based universities, focused on a twenty-year period from 2004 to 2023. They gathered data from ten countries, including Nigeria, Guinea, Cameroon, Comoros, Lesotho, Eswatini, Tanzania, Angola, Tunisia, and Egypt. They treated the number of commercial bank branches per 100,000 adults as a measure of how easy it is to physically reach a bank. They also looked at the number of deposit accounts per 1,000 adults to measure how many people were actually using the system to save money. By comparing these numbers against the annual growth rate of each country's real Gross Domestic Product (a standard measure of the total value of goods and services produced), they hoped to find a clear link between having a bank account and a thriving economy.
What they found, however, was a surprise that challenges the standard playbook. Instead of finding that more branches and more accounts led to faster economic growth, the data showed the opposite. The study revealed that in these ten countries, an increase in the number of bank branches was actually associated with a decrease in economic growth. Similarly, a rise in the number of deposit accounts was linked to a drop in growth. The numbers were not just a little off; the relationship was statistically strong and negative. For every additional bank branch per 100,000 people, the growth rate of the economy tended to fall. The same was true for savings accounts: as more people opened them, the economy grew more slowly, not faster.
This does not mean that banks are bad or that saving money is harmful. Rather, the researchers suggest that the mere existence of these financial tools is not enough. In the countries studied, the physical branches often sit in urban centers where banking is already common, while rural areas remain empty. These branches may be expensive to run and may not be lending money to the people who need it most to build businesses. Instead, the money might be sitting idle or being used for short-term consumer loans that do not create long-term wealth. Similarly, having a deposit account does not guarantee that the money inside is being used productively. If a person saves money but the bank does not lend that money to a farmer or a factory owner, that savings does not help the economy grow. The study indicates that in these specific African nations, the financial system is expanding in size but not in effectiveness.
The authors conclude that simply building more branches or encouraging more people to open accounts is not a magic bullet for economic development. The negative results suggest that the current way these banks operate is not connecting with the real economy. The money is moving, but it is not moving into the productive sectors that create jobs and goods. The researchers argue that for financial inclusion to truly help, the focus must shift from just counting branches and accounts to ensuring that the money flowing through them is actually being used to build factories, farms, and businesses. Until the financial system becomes more efficient at turning savings into real investment, having more banks and more accounts might just be a sign of a system that is busy, but not necessarily helpful.
