ASIC Market Integrity Rules (Securities Markets) Amendment Instrument 2026/574
ASIC Market Integrity Rules (Securities Markets) Amendment Instrument 2026/574 changes parts of the rules governing Australian securities markets, with particular attention to trading systems, trading algorithms and related terminology. Registered as F2026L01223, it amends the ASIC Market Integrity Rules (Securities Markets) 2017.
Business implications
For market participants and brokers, the practical relevance includes mapping existing systems and procedures to the revised definitions and requirements before commencement. Technology inventories, supervision procedures and documentation of client instructions may be useful starting points, particularly where automated functionality is supplied by an external provider. A label such as “order-routing software” does not by itself establish whether all of the system’s functions fall outside the trading-algorithm definition.
