AUSTRALIA: ASX Clear Announces Amendments to the Operating Rules

Friday April 17 2026

On 17^th April 2026, ASX Clear Pty Limited (ASX Clear) announced that it has received regulatory clearance in November 2025 for rule amendments to the ASX Clear Operating Rules (ASXCOR) and supporting amendments to the ASX Clear Operating Rule Procedures, including:

• Amending ASX Clear Operating Rule 12.2.1 to remove the requirement that Approved Market Operators (AMOs) include both a delivering and receiving participant ID (PID) in the particulars of a Cash Market Transaction submitted to the CS Entities by an AMO. This change is on the basis that the CHESS replacement system does not provide the functionality for a Trading Participant ID to be linked with more than one clearer;
• Deleting ASX Clear Operating Rules 12.7.2 – 12.7.5, 12.7.7, 12.7.8 and amending Operating Rules 12.7.6, 12.7.9. 12.8.1 and 12.8.5 to remove the ability for Clearing Participants to request that Cash Central Counterparty (CCP) Transactions be removed from novation and set-off and be excluded from set-off. Clearing Participants who wish to request a Cash CCP Transaction be removed from novation and set off or excluded from set off on Trade Date, will continue to have the option of requesting their AMO cancel the Cash Market Transaction on their behalf;
• Amending ASX Clear Operating Rule Procedure 1.17.1 to specify that the new AMO User Technical Documentation (which is replacing the CHESS External Interface Specification (EIS) as it relates to AMOs) is subject to the Operating Rule relating to intellectual property included within the ASX Clear Operating Rule 1.17.

The amendments to the Rules and Procedures facilitate the implementation of Release 1 of the Clearing House Electronic Subregister System (CHESS) replacement system and will become effective on 20 April 2026.
