Everything you need to keep up to speed on regulatory and conformance requirements in the open banking ecosystem. 


Regulatory background

In 2016, the Competition and Markets Authority (CMA) published a report on their investigation into competition and innovation in the retail banking industry. They found that big banks dominated the market and consumers and small businesses would benefit from increased competition.

To remedy this, the CMA and UK government mandated nine of the largest banks to implement common standards for open banking. This would ensure that there were standard APIs that allow customers to securely share their financial data or safely initiate transactions. Trusted companies could use these APIs to offer new innovative services to customers and SMEs increasing competition. The original Order and subsequent regulatory documents are available below.

The open banking roadmap

On 15th May 2020, the OBIE’s revised Roadmap was published following a comprehensive and structured consultation process that OBIE managed at the instruction of the Trustee.

The process included two distinct phases of consultation, open workshops and the assessment of over 75 pieces of feedback, received from a cross-section of stakeholders including the CMA 9, non-CMA 9 banks, third party providers and end user representatives.

2020 was a transformational year for open banking and for the OBIE. This report provides an overview of the OBIE’s activities for 2020 and 2021.

Revised Payment Service Directive (PSD2) and The Payment Services Regulations 2017 (PSRs)

PSD2 is an EU directive which came into force in January 2018. PSD2 is aimed at driving innovation, competition and improvement of customer protection and payments security with the payment services industry.  

For open banking, this means a focus on attracting new account information service providers (AISPs), payment initiation service providers (PISPs) and card-based payment instrument issuers (CBPIIs). They also need access to online payment accounts at account servicing payment service providers (ASPSPs) to provide their services to customers.
