The recent emergence of financial technologies (Fintech) in the countries of the West African Economic and Monetary Union (WAEMU) has sparked growing interest, particularly with regard to their impact on the health sector. This study analyses the contribution of Fintech to the performance of health systems in the eight countries of the Union over the period 2011-2021. Methodologically, it uses two approaches : the double bootstrap DEA method developed by Simar and Wilson (2007) and the quantile moments method developed by Machado and Silva (2019). The results indicate that healthcare systems in the region are marked by technical inefficiency, with an average corrected score of 55.3%. Furthermore, the positive effect of Fintech appears to be particularly pronounced in countries with the lowest levels of healthcare performance (quantiles 10, 25 and 50). JEL classification: O33, D24, I10, C15, C21. Keywords: Fintech, Performance, Health Systems, Double Bootstrap DEA, Quantile Moments.
