The Australian Securities Exchange (ASX) is pushing to speed up the final step of a share trade, aiming to move cash-equity settlement to a one-day cycle (T+1) even though its long-awaited CHESS system overhaul won't be finished until 2029.
CEO Anthony Attia said the exchange will consult with regulators and market participants on the move, according to a statement. The shift would bring Australia in line with a growing global trend toward faster settlement.
What is settlement and why does it matter?
Settlement is the process where cash and shares actually change hands after a trade is executed. When you buy a stock, the trade is agreed instantly, but the transfer of ownership and payment typically takes a couple of days to complete. Australia has operated on a two-day cycle (T+2) since 2016.
Shortening that to one day (T+1) means investors get their shares or cash sooner, reducing the risk that a trade fails because one party can't deliver. It also frees up capital that would otherwise be tied up during the settlement window.
The push comes as global markets accelerate. The United States already moved to T+1 in 2024. London and Euronext plan to switch next year, and Hong Kong is targeting late 2027. Australia risks falling behind if it doesn't act, according to Attia.
Why the delay? The CHESS overhaul
The ASX has been working on replacing its CHESS clearing and settlement system for years. The project has faced multiple delays and cost overruns, with the current timeline targeting completion in 2029. The exchange explored T+1 in 2024 but paused after brokers and other market operators argued that stabilizing the roughly A$445 million technology project should be the priority.
Now, Attia says the exchange wants to move forward with T+1 consultation in parallel with the CHESS work. That suggests the ASX believes it can achieve faster settlement without waiting for the full system replacement.
But the path isn't straightforward. Moving to T+1 requires changes across the entire market ecosystem, including brokers, custodians, and clearing houses. Many smaller players may need to upgrade their systems and processes, which can be costly and time-consuming.
What it means for investors
For everyday investors, the practical impact of T+1 is relatively simple: you'd get your money or shares a day earlier than you do now. That could be helpful if you're selling shares to free up cash quickly, or if you're buying and want to ensure the trade settles before a corporate action like a dividend payment.
It also reduces the risk of settlement failures, which can happen when a buyer or seller doesn't deliver on time. In a T+1 world, there's less time for something to go wrong.
However, the transition could bring some short-term friction. Investors may need to ensure their brokers have the necessary systems in place, and there could be a period of adjustment as the market adapts. The ASX's consultation will likely address these operational details.
Broader market context
The move comes as Australia's financial markets face a mix of challenges and opportunities. Business confidence has been soft, with a recent survey showing a slide to -13 as costs bite. The job market remains steady but shows signs of slack, and Westpac's leading index points to slow growth ahead.
On the positive side, Australia's bond market has been active, with foreign issuers piling in and setting a 2026 issuance record. The country's AAA rating was recently affirmed by Fitch, though with warnings on debt and rates.
For the ASX, faster settlement could make the exchange more competitive globally, potentially attracting more international investment. It also aligns with the trend toward greater efficiency in financial markets.
What to watch next
The consultation process will be key. Market participants will want clarity on the timeline, the costs involved, and how the transition will be managed. The ASX will need to balance the desire for speed with the need for stability, especially given the history of the CHESS project.
Investors should keep an eye on announcements from the ASX and regulators about the consultation timeline and any proposed implementation dates. While T+1 is likely to happen eventually, the exact timing and details remain uncertain.
In the meantime, the broader market continues to evolve, with Glencore debuting on the ASX and other developments shaping the investment landscape. For now, the ASX's push for T+1 is a sign that Australia wants to stay in step with global markets, even if the full system overhaul is still years away.
