What is open banking? 

Open banking is a secure way for customers to take control of their financial data and share it securely with organisations other than their bank.  

By sharing this data with authorised third parties, customers can access services that help them make more of their money. This could mean access to smart savings apps, finding better mortgage rates or accessing credit. Businesses can also use open banking – for example, to manage cash flow or make it easier to receive payments. 

The Open Banking Implementation Entity was set up by the Competition & Markets Authority (CMA) in September 2016 to fulfil one of the remedies mandated by the CMA following an investigation into competition in UK retail banking. The open banking ecosystem is designed to deliver fairer, more transparent banking and financial services. 



Open banking is the technology that’s being developed and leveraged by a growing network of providers, products and services that make it all happen. 

We are the Open Banking Implementation Entity (OBIE). We were created by the CMA to deliver the Application Programming Interfaces (APIs), data structures and security architectures that power open banking. Our frameworks empower developers to build systems that make it easy and safe for customers to share their financial information with third parties. 



The OBIE is a private body; our governance, composition and budget are determined by the CMA.  

OBIE is funded by the UK’s nine largest current account providers (often called the CMA9) and overseen by the CMA, the Financial Conduct Authority and Her Majesty’s Treasury.  

The nine mandated institutions are: AIBG, Bank of Ireland, Barclays, Danske, HSBC, Lloyds Banking Group, Nationwide, Natwest Group and Santander.

Consumer outcomes

The OBIE does not ‘log’ open banking activity in the way that a traditional payment infrastructure might. This is because no open banking activity flows through the OBIE platform. Our best window on the breadth of open banking activity comes from the Open Banking App Store.

Real benefit to businesses

Businesses’ adopting solutions like cloud accounting and cashflow forecasting indicate the importance of clarity and control over their finances. As a growing number of businesses resort to eCommerce to meet customer demand, we anticipate payments to be a key area of growth for small businesses in 2021 and beyond.
