Implementation of SDGs is the unified goal of 193 UN Member States. FinTech plays a crucial role in achieving it. Therefore, the development of FinTech must be facilitated through proper policy-making and public finance, creating beneficial PEST conditions. However, the interaction of the FinTech PEST environment and achievement of SDGs is a topic that has not yet been addressed. The purpose of this study is to assess the link between these two indicators using statistical methods, indicate SDGs having the strongest link to FinTech PEST environment, and explain the interface to facilitate its useful application within government and financial regulations, as well as administration of the state and municipal financial entities. The results show that the economic and investment potential of Northern Europe is caused by the most favorable PEST environment for FinTech sector development, and demonstrate the existence of a statistical link between FinTech PEST environment and SDG4, SDG8, SDG9, SDG16. There is a clear trend – the more favorable the FinTech PEST environment, the better the achievement of SDGs, the better results of Sustainable Finance indicators, and the higher the Sustainable Finance typology assigned to the country. These results suggest that the goals, targets, and indicators of SDG4, SDG8, SDG9, and SDG16 contribute to the formation of a favorable environment and are conductive to the sustainable development of the FinTech industry in a country. Therefore, sustainability in the development of FinTech industry and finance, and the achievement of SDGs, is a circular process of three interacting factors.
