Abstract
With the development of sharia economy in Indonesia, there are now many fintech companies that use sharia system. This research discusses the regulation of sharia-based fintech and its legal position in Indonesian law. This research is a normative research. The results show that fintech is generally regulated by OJK and BI regulations. For sharia-based fintech, the application of sharia principles only relies on the DSN-MUI fatwa. The lack of specific provisions regarding sharia principles for sharia-based financial technology in OJK and BI Regulations may weaken the obligation to comply with sharia principles. Indeed, the DSN-MUI fatwa itself, given its place in national law, only has binding legal force if it is regulated by legal provisions or if those legal provisions give a special place to the DSN fatwa itself. The government should immediately take binding regulations regarding the application of sharia principles in sharia-based fintech in Indonesia.
