Sustainability, which we could define as taking into account all of human activities collectively and the requirements of future generations rather than simply today's conditions or possibilities, also implies that for something to be sustainable, there must be continuity and renewability. By concentrating on the challenges that occur in the areas of social and environmental need, social finance, which we may consider inside or in conjunction with this idea, refers to financial services that endeavor to provide funds to accomplish a social purpose. Social and financial gains are integrated in sustainability and social finance. In this context, the research's goals are to conceptually analyze social impact bonds in the context of sustainability and social finance, to thoroughly assess the current situation, particularly with regard to social impact bonds, and to establish a data set for the future decisions that will have to be taken. Throughout the examinations, it was observed that the idea of social finance, which has several application areas, has gained prominence subsequently. Particularly noticeable are the steady increases in the issuing of social impact bonds since 2013 and the jump in the COVID-19 pandemic period, particularly in 2021. It is reasonable to describe this condition as striving toward the eradication of the requirements of the pandemic situation, the issues encountered in the area of supply, and the results of large-scale economic difficulties.
