In an AGM address, its chairman confirmed the exchange is still on-track for go-live in April 2025.One of the primary factors contributing to these setbacks has been the sheer complexity of replacing such a critical piece of market infrastructure.

The National Stock Exchange of Australia (NSX) is a stock exchange company that has finished working on a distributed ledger technology (DLT) trading system.

Tripling Capacity: Adapting to Market Demands

The decision to triple the capacity of the DLT system underscores the ASX's commitment to building a future-proof platform capable of handling the evolving demands of the Australian financial markets. 基於dlt的系統原定於12月進行正式試驗，計劃於2025年初啟動。 在今年的年會上，ASX執行長多米尼克 史蒂文斯（Dominic Stevens）告訴股東，他們希望基於三月初看到的貿易量激增，使其計劃的DLT系統的容量增加三倍。This expansion reflects a proactive approach to address potential bottlenecks and ensure the system can accommodate future growth in trading volumes.

Why Tripling Capacity Matters

• Enhanced Scalability: A system with triple the capacity can handle significantly larger trading volumes without experiencing performance degradation or delays. According to an Oct. 28 update from the ASX, the exchange has officially delayed the rollout of distributed ledger technology (DLT) infrastructure to replace its current system for processingThis ensures the smooth functioning of the market during peak periods and reduces the risk of system outages.
• Future-Proofing: The Australian financial markets are constantly evolving, with new products and trading strategies emerging regularly.Investing in a high-capacity DLT system ensures the platform can adapt to future growth and innovation without requiring costly and disruptive upgrades.
• Increased Resilience: A more robust system is better equipped to withstand unexpected surges in trading activity or potential disruptions.This enhanced resilience is crucial for maintaining market stability and investor confidence.

The additional capacity will allow the ASX to comfortably manage peak trading volumes, even during periods of heightened market volatility or unexpected events.This is particularly important in today's interconnected global financial markets, where events in one region can quickly impact trading activity in others.

Regulatory Expectations and Oversight

The Australian Securities and Investments Commission (ASIC) and the Reserve Bank of Australia (RBA) play a crucial role in overseeing the ASX and its CHESS replacement project.These regulatory bodies have outlined their expectations for the new DLT-based system, emphasizing the importance of safety, reliability, and efficiency.

Key regulatory expectations include:

• Robust Risk Management: The new system must have comprehensive risk management controls in place to mitigate potential threats to market stability and investor protection.
• Operational Resilience: The platform needs to be highly resilient to operational disruptions, with robust backup and recovery mechanisms in place.
• Compliance with Regulatory Requirements: The DLT-based system must comply with all applicable laws and regulations, including those related to data privacy, anti-money laundering, and counter-terrorism financing.
• Transparency and Auditability: The system should provide clear and transparent records of all transactions, allowing regulators to effectively monitor market activity and ensure compliance.

The regulators have stressed the need to replace the current CHESS system as soon as can be safely achieved.They recognize the potential benefits of DLT but also emphasize the importance of a carefully planned and executed transition to minimize risks.Regular audits and assessments are part of the continuous oversight.

The Potential Benefits of a DLT-Based CHESS System

Despite the challenges and delays, the ASX remains confident that the DLT-based CHESS replacement will deliver significant benefits to the Australian financial markets.The potential advantages of adopting this technology are substantial.

Key Advantages of DLT in Clearing and Settlement

1. Increased Efficiency: DLT can streamline clearing and settlement processes by automating manual tasks and reducing the need for intermediaries.This can lead to faster transaction times and lower costs.
2. Enhanced Transparency: DLT provides a shared, immutable ledger of all transactions, increasing transparency and reducing the risk of fraud or errors.
3. Reduced Costs: By eliminating intermediaries and automating processes, DLT can significantly reduce the costs associated with clearing and settlement.
4. Improved Risk Management: DLT can provide real-time visibility into transaction data, allowing for better risk management and more timely detection of potential problems.
5. Greater Innovation: A DLT-based platform can foster innovation in financial products and services by providing a more flexible and efficient infrastructure for developing new offerings.

For example, the increased efficiency could significantly speed up settlement times for trades, potentially moving from the current T+2 (two business days after the trade date) to T+0 or T+1.This would free up capital faster and reduce counterparty risk.Similarly, enhanced transparency would make it easier for regulators to monitor market activity and detect potential abuses.

The National Stock Exchange of Australia (NSX) and DLT

While the ASX's journey with DLT has been fraught with delays, it's worth noting that the National Stock Exchange of Australia (NSX) has also been exploring the potential of this technology. In November 2025 the Australian Securities Exchange (ASX) paused work on a DLT-based replacement of its CHESS settlement system on which it had spent more than US$169 million and wrote off the investment.The NSX has completed work on its own DLT trading system and is awaiting regulatory approval to connect to the ASX. Today, the Australian Securities Exchange s regulators outlined their expectations for the DLT-based CHESS replacement system. They emphasized the importance of replacing the system as soon as can be safely achieved .The success of the NSX's DLT initiatives could provide valuable insights and potentially accelerate the adoption of DLT in the broader Australian financial market.
