ASX technology spend rises as CHESS overhaul rolls on

ASX will lift capital spending to A$180 million to A$200 million in the financial year from 1 July as the exchange operator pushes ahead with technology upgrades after years of delays to its CHESS replacement. Bloomberg reported that the new range compares with an earlier A$160 million to A$180 million forecast and comes as ASX continues work on systems used for trading, clearing and settlement.

The increase makes the update as much an enterprise-infrastructure story as a markets one. In its February half-year results presentation, ASX had guided to FY26 capital expenditure of A$170 million to A$180 million. Raising that range within months suggests the exchange still expects heavy spending on software, testing and operational resilience as it tries to rebuild confidence after years of scrutiny over the CHESS programme.

On its CHESS project page, ASX said all planned Release 1 operational milestones had been completed by 5 May and the programme had moved from Hypercare Stage 1 to Stage 2. Bloomberg said the broader overhaul is expected to run through 2029, leaving brokers, listed companies and investors watching whether milestone updates translate into a steadier production system.

For ASX, the higher capex matters less as a growth signal than as an execution one. Exchanges sit at the centre of market plumbing, so technology spending tends to show up in testing, integration work and the capacity to support live releases. The question for customers is whether the added budget shortens the path to a stable post-CHESS stack or simply reflects the long tail of a delayed programme.

ASX had already flagged technology as a major investment line in its February materials. The earlier guidance implied spending would peak at A$180 million. The new range lifts the ceiling by A$20 million and sharpens the task for incoming chief executive Anthony Attia: show the market that extra spending is producing visible progress.

That matters to brokers and issuers because CHESS is not a side project. It underpins settlement, corporate actions and the flow of confirmations across the listed market. A higher capex line is easier to defend if it buys reliability, clearer accountability and fewer resets. If not, customers are likely to treat it as another sign that ASX’s modernisation effort remains expensive and unfinished.

The revised spending plan therefore lands as a fresh Australian infrastructure update rather than a routine budget change. ASX is signalling that restoring confidence in its core systems will cost more and take longer than previously outlined. The next measure is whether that extra capital produces visible progress well before 2029.
