Update: Summary of key proposed changes

At the request of the Expert Advisory Group (EAG) that has been assisting in developing the proposed changes, we have summarised these in an additional document providing a supporting rationale for the proposed approach. 

Moving to the new framework

Feedback from the EAG indicated that it would be useful to address key implementation issues facing the open banking ecosystem which are significant in determining optimal approaches to transitioning to the new regulatory framework but may only have a modest impact on the Standard.

We have set out some analysis on the various approaches identified in EAG discussions and developed conclusions as to a possible common approach.   

This document also contains several specific questions on each of the topics covered which we hope will assist respondents to frame their input to the consultation.

We welcome responses to the consultation from all interested parties. Written consultation responses are due by 12pm on 4 March 2022.
