Abstract The belief that digitisation directly contributes to promoting financial development and economic growth has occupied much of development policy discourse of most governments and international development organisations over the past decades. It was therefore necessary to: examine the effect of digitisation on financial development; examine the sensitivity of the indicators of digitisation to financial development; and explore the effect of digitisation and financial development on economic growth. Secondary data on 30 emerging economies and between the period of 2004 to 2017 from World Bank’s World Development Indicators (WDI) database and the International Telecommunications Union were used in the estimations. The Generalised Method of Moments (GMM) estimations were used to analyse the data. On the determinants of financial development, digitisation was found to have a statistically significant effect.
