The Australian Securities & Investments Commission has finalized changes to its Market Integrity Rules that strengthen controls over automated and AI enabled trading while streamlining requirements for securities and futures market participants. Following its 2025 consultation, ASIC extended the transition period to 18 months, with the amended rules taking effect in 2028. The technology neutral reforms require stronger testing, monitoring and governance of trading systems and all algorithms, including those using AI and machine learning. They apply trading system requirements consistently to manual and automated orders, establish more consistent standards across securities and futures markets, and clarify when trading activity may create a false or misleading appearance. The amendments also align the Australian framework more closely with International Organization of Securities Commissions principles and remove redundant or overly prescriptive obligations. ASIC is separately consulting on updated guidance to support implementation. The proposals would consolidate Regulatory Guides 265 and 266, incorporate relevant electronic trading guidance so Regulatory Guide 241 can be retired, and reduce the relevant guidance for securities participants by almost 60%.
