Introduction. The Inception of Open Banking. Open banking is a silent revolution transforming the banking industry. It is the manifestation of the revolution of consumer technology in banking and will dramatically change not only how we bank, but also the world of finance and how we interact with it. The book aims to help simplify, define and explore ‘open banking’ as well as the concepts of ‘open finance’ and ‘open data’. It examines how customer financial data is collected and used by fintech firms and surveys and how a number of key jurisdictions (EU, UK, India, Singapore, and Australia) are implementing open banking.
