Open banking has become an ubiquitous phenomenon across financial institutions. What was at first touted to be a threat to the traditional banking industry has now become a business opportunity for many. According to research, open banking market size will reach $43.15 Billion by 2026, at 24.4% CAGR.


In the modern world, open banking has empowered banks as well as other financial institutions to share their repository of financial data with non-bank third parties through APIs or open application programming interfaces. Third parties can this way embed their services with banks in order to create an improved consumer experience. In this blog, we will highlight how open banking can accelerate innovation for traditional banks as well as fintech. Let us start by understanding what open banking is.

What is open banking?

Open banking is touted as a paradigm that enables banks to make raw account data available to third parties through a set of APIs in a regulated and secure way. Third-party providers which include other banks, retailers, fintechs, telecoms, insurers and wealth managers, etc. can therefore use their APIs to integrate the data in their apps to offer better products and services to their customers. Open banking makes use of open source technologies to offer greater financial transparency and private as well as open data control options for customers. It opens a whole new assortment of digital business landscapes through APIs offered by the FIs.

Third parties are also capable of enabling bank-to-bank transactions for payments on behalf of the customer, but with appropriate permissions. The best part of APIs is that the publishing bank does not need to worry about how the data and component services they offer are being used, as regulations are all taken care of by third parties.

Open banking for customers
