Pulse Analysis

The Australian Securities Exchange’s CHESS (Clearing House Electronic Sub‑register System) has been the backbone of post‑trade settlement for decades. By partnering with Tata Consultancy Services, ASX is replacing legacy technology with a cloud‑native architecture that aligns with global best practices. Release 1, now in production, delivers a high‑performance clearing engine that leverages TCS BaNCS and the Quartz Gateway, enabling real‑time trade novation, netting, and straight‑through processing for equities, bonds and derivatives.

From a technical standpoint, the new platform is engineered for scale. Benchmarked to handle more than 20 million trades per day, it supports ISO 15022, ISO 20022 and FIX messaging standards, ensuring seamless connectivity with domestic exchanges and international participants. Hosting the solution in the cloud provides elasticity, fault tolerance and rapid provisioning of resources, which translates into lower latency and higher resilience during market stress. The architecture also embeds robust security controls, meeting the stringent regulatory requirements of Australia’s financial market infrastructure.

Strategically, the CHESS Release 1 go‑live signals a broader shift toward digital modernization in the Asia‑Pacific region. It reduces settlement risk, shortens processing cycles, and prepares the market for the growing demand of multi‑asset, high‑frequency trading. With Release 2 slated for 2029, ASX and TCS aim to extend these capabilities, adding advanced analytics and further automation. The successful rollout reinforces TCS’s reputation as a leading provider of end‑to‑end market‑infrastructure solutions and sets a benchmark for other exchanges contemplating similar upgrades.
