5 million users – open banking growth unpacked

24 February 2022
The OBIE recently celebrated passing the 5 million open banking users milestone. Here we take a look back at 2021 and how our thriving, world-leading ecosystem delivered this impressive growth.

2021 Insights:  

Regulated Providers  

By the end of 2021 there were 337 regulated providers enrolled in the OBIE Directory – up from 294 at the close of 2020. This growth points to the continued value firms receive from direct participation in open banking. 

Payments made using open banking: 

At the end of 2021, cumulatively over 26.6m open banking payments had been made. An increase of more than 500% in 12 months. 

Ecosystem Numbers (December 2021)  

  • 337Regulated Providers   
  • 245Third Party Providers   
  • 92Account Providers 
  • 124 regulated entities with at least one proposition live with customers   

OBIE’s GOALS for 2022  

  • Help to foster competition and innovation by continuing to add new FinTech’s to the ecosystem and supporting them to bring new and exciting propositions to market. 
  • Continue to strengthen the corporate governance and culture of the organisation 
  • Work to ensure that as we approach transition, the collective effort, hard work and investment that has already gone into establishing open banking in the UK is extended to other sectors.

Charlotte Crosswell, Chair & Trustee, OBIE said: 

“2021 was a year of growth for open banking in the UK. We witnessed a 60 per cent increase in the number of active open banking users, with adoption increasing at a rate of approximately one million new users every six months. Similarly, OB payments increased by an impressive 500 per cent year on year. The OBIE navigated a number of difficult challenges, but sought to listen, learn and reform as a number of organisational, governance and cultural changes were made. As we move forward in 2022 and these internal improvements continue, we want to see the growth momentum that took us to the recent 5 million user milestone continue.”
