Open Banking requires banks to open customer data to third parties in an effort to enable more competition and customer control. In this article, we will highlight how customers, banks and third parties may benefit altogether from Open Banking and what technical impact it will have on banks’ IT infrastructure.

The idea of Open Banking

«Open Banking» defines a customer-oriented banking concept. It includes the opening of banks, as well as the provision of customer data against third-party (financial) service providers. Operations on bank accounts and data, including financial services, are made available to third parties through publicly available, standardized APIs, provided that customers agree. Thus customer data and services, as well as related functionalities, can be exchanged between banks and thirdparty providers. This opens up entirely new possibilities for customers, e.g. direct access to a variety of financial services from different providers on a single platform. As a result, competition on the financial market will increase. Customers benefit from more transparency, selection and control over their own data.
