Is financial digitalization always beneficial for all countries?

This paper investigates whether financial digitalization contributes to economic growth and whether it leads to benefits that are distributed evenly across regions or across income groups even within the same country. The analysis based on the recent panel data including the COVID-19 pandemic period reveals that financial digitalization accelerates economic growth, particularly in developed countries where digital transformation and traditional finance are both well developed. The more widespread and frequent use of digital payment by the bottom 40% of the population in developed countries positively affects economic growth and reduces the domestic income inequality. However, Asian and African countries struggle to benefit from these positive effects.
To address the seemingly counterintuitive finding from the panel data analysis that digital financial deepening has a negative impact on developing countries, this paper applies a panel threshold regression with the level of traditional financial deepening as a threshold variable. This analysis focuses on 35 African countries since 2000. The results indicate that African countries with comparatively underdeveloped traditional financial systems experience significant gains from financial digitalization, except in the aftermath of the global financial crisis. More recently, countries with more mature banking systems have also leveraged digital transformation in their economic growth processes.
Furthermore, to examine whether financial digitalization benefits all African countries equally or whether it favors some disproportionately, this paper conducts a convergence analysis of per capita outputs for 24 African countries over the period 1961–2022. The results suggest that the finance-related ICT variables in seven African countries, including Kenya and Tanzania, can push up their growth paths to converge towards that of the Republic of South Africa. These countries, particularly Kenya, implement the ICT-oriented national policies to become a technological and innovation hub in East Africa, which likely contributes to these results. More importantly, digital infrastructure development can be especially beneficial for countries with initially underdeveloped traditional financial systems—Botswana, Burkina Faso, Cameroon, and Tanzania. Digital finance appears to be acting as a substitute for traditional finance in these countries. -
