The objective of this article is to analyze the effect of mobile money on financial inclusion in Cameroon. To carry out this work, it was necessary for us to analyze the effect of this adoption on the facilitation of access to financial services for households in Cameroon, and to analyze its effect on the mobilization of savings. Thus, we adopted a hypothetico-deductive approach, and collected data from several sources between 2011 and 2018, including Global Findex, Finscope and COBAC. Stationarity tests followed by series cointegration tests for the analysis of cointegration relationships between variables then led us to choose and estimate our econometric model by VAR regression, in order to capture in depth the reciprocal influence of the selected variables. The results show that holding a mobile money account thanks to accessibility significantly influences the facilitation of access to financial services for Cameroonian households.
