The Evolution of FinTech: A Review of Technologies, Business Models, Regulation, and Future Research Directions

The Financial Technology (FinTech) ecosystem has become a disruptive one which changed the face of the financial services industry with digital technology, innovative business models and new regulatory framework. The development, distribution and use of financial products and services have been revolutionized by technologies like artificial intelligence, blockchain, cloud, big data analytics, Internet of Things and open banking. This review paper aims to integrate and consolidate the available literature to gain an overview of the development of FinTech from Finance 1.0 to Finance 4.0, and their technological innovations as the backbone of the modern financial systems. It also explores some of the key FinTech business models like digital payments, digital lending, WealthTech, InsurTech and embedded finance, and the essential role of relevant government policies, digital public infrastructure and governance for responsible FinTech innovation. The paper also identifies relevant challenges in the fields of cybersecurity, data privacy, ethics in artificial intelligence, regulatory complexity and digital inclusion that remain to significantly impact the sustainable development of the FinTech ecosystem. Last but not least, new research opportunities are identified in the field of generative artificial intelligence, decentralized finance, green FinTech, and digital financial governance to be pursued by academia in the future. The multidisciplinary perspective employed in this review gives a comprehensive picture of the current developments in FinTech and can help researchers, practitioners and policymakers to understand the opportunities and risks associated with digital financial transformation.
