ASX Begins Publishing Company Announcements After Major Platform Outage

The Australian Securities Exchange (ASX) has resumed publishing some company announcements after experiencing a significant outage early Monday. According to updates on the ASX website, the issues began just before 9:00 a.m. local time (2200 GMT), disrupting the market announcement platform that companies rely on to release price-sensitive information.

ASX confirmed that it has started uploading announcements received after 11:22 a.m. (0022 GMT), though a substantial backlog remains. Earlier disclosures are still affected, and the exchange said it is working toward fully restoring the system. During the outage, companies scheduled to release critical information were placed in trading halts to maintain market integrity. ASX noted that around 80 stocks are currently halted, though trading and settlement operations continue to function normally.

This latest disruption adds to ongoing concerns surrounding ASX’s operational reliability. The exchange has faced increasing scrutiny from regulators, including the Australian Securities and Investments Commission (ASIC) and the Reserve Bank of Australia (RBA), following repeated system issues. In September, the RBA criticised ASX’s governance, culture, and risk-management practices after a major settlement-system malfunction in December 2024 highlighted weaknesses in the exchange’s market infrastructure resilience.

The outage also comes on the heels of another major market disruption overseas. On Friday, U.S.-based CME Group, the world’s largest exchange operator, suffered one of its most prolonged outages in years, temporarily halting trading across equities, bonds, commodities, and currency markets.

ASIC confirmed it is actively engaging with ASX regarding the platform failure, while the RBA has yet to comment. Market reaction has been swift, with ASX shares dropping 2.46% to A$56.78 in early Monday trading. The broader S&P/ASX 200 index also slipped 0.3% by 0127 GMT.

The incident underscores ongoing concerns about the stability of key financial infrastructure and highlights the urgent need for robust technological systems to support Australia’s financial markets.
