Special Note for Account Opening

Following a number of working groups with stakeholders, ASX has been asked to consider reducing the complexity to support account opening. ASX is currently undertaking a review, with considerations given to the number of messages, sequencing and workflows.

ASX wishes to advise vendors and Participants of the high probability that there will be updates to the messages and associated workflows. Any changes to the Account opening process will be provided in a subsequent update. 

Consequently, ASX will populate the CDE with account data to facilitate testing. Refer to the below Test Data link for further details.
