CHESS Replacement

A secure & contemporary replacement system using global standards.
Offering a better way to deliver market efficiencies and innovation opportunities.

Building core and contemporary infrastructure to advance Australia's reputation as a leading economy

ASX is replacing CHESS, its well-functioning but ageing clearing and settlement system, with enhanced technology that will create new opportunities for the Australian market. When it goes live, the new system will offer richer functionality, adopt global standards and use contemporary technology.

It will also provide the option of accessing distributed ledger technology (DLT), which will deliver information more efficiently and stimulate competition by enabling anyone to build new services.

ASX has a history of innovating and upgrading systemically important systems. It is part of what we do. We believe this new system - sitting on new infrastructure - will create a foundation for the next decade and beyond.
