The Australian Stock Exchange — ASX Ltd (ASX:ASX) itself — is facing a rockier week than many of the companies whose shares it hosts, with operational missteps, unexpected financial setbacks, and increasing competition threatening its market dominance.
A significant error on Wednesday involving TPG Telecom shares triggered a temporary market disruption, followed by the ASX on Thursday revealing a $25 million–35 million operating expense hit due to an ongoing inquiry by the Australian Securities and Investments Commission (ASIC).
And in a potentially more existential development, ASIC on Thursday announced it close to allowing US-based exchange giant Cboe to compete directly with the ASX. The slew of bad news prompted the local exchange’s shares to drop nearly 9% by Thursday afternoon.
TPG Telecom blunder causes disruption
In a rare slip-up, the ASX on Wednesday morning mistakenly linked TPG Telecom (ASX:TPG) to a takeover bid for Infomedia (ASX:IFM) that actually involved TPG Capital Asia, triggering confusion among investors and wiping $400 million off the telecom company’s market capitalisation in a single day.
The error, which stemmed from a human mistake in processing an announcement, affected trading of TPG Telecom shares for about 15 minutes before the market paused trading. It resumed later in the day, and the ASX ultimately cancelled the pre-pause TPG Telecom trades, but the company’s shares nonetheless ended the day down 5.1%.
“This issue arose from an inadvertent human error, and I recognise that it has caused disruption for TPG Telecom and its investors,” said Darren Yip, ASX group executive markets and listings. “Upon discovery of the mistake, it was escalated to me, and I will be apologising directly to the team at TPG Telecom.
“This mistake shouldn’t have happened, and we are reviewing our internal processes to understand if there are additional safeguards or procedures we could implement to reduce the risk of a similar occurrence.”
Financial hit from ASIC inquiry
The exchange also revealed that it expects to incur an additional $25-35 million in operating expenses for FY26 as part of its response to the ongoing ASIC inquiry.
The inquiry, which focuses on ASX’s governance, risk management, and systems, is expected to result in increased staffing, legal costs, and other related expenditures.
“When we last updated the market on 16 June, we acknowledged the ASIC inquiry had only just been announced,” ASX CEO and managing director Helen Lofthouse said. “Since then, we’ve completed our assessment of the range of expenses we expect to incur in relation to the inquiry. We remain committed to our five-year strategy and are focused on our technology modernisation and uplifting operational risk management and resilience.”
Rival exchange Cboe on the horizon
In a further blow to the ASX, ASIC is considering a market listing application from Cboe Australia, a subsidiary of US-based exchange giant Cboe Global Markets. This move could intensify competition in Australia’s capital markets, as Cboe’s entry would provide a new platform for companies to list, potentially siphoning business from the ASX.
ASIC’s efforts to expand competition include licensing Cboe’s US and Canadian exchanges and facilitating the dual listing of foreign companies in Australia. The move is designed to offer Australian investors more choice and improve market access, with a particular focus on attracting foreign capital.
“As superannuation funds grow and investors seek opportunities, our actions will help keep our markets efficient, innovative and attractive, supporting economic growth for all Australians,” said ASIC chair Joe Longo.
Already reeling from a troubled governance record and recent operational failures, the ASX will need to recover its footing quickly to avoid further erosion of investor confidence. As it works to address regulatory concerns, the arrival of a formidable new competitor in Cboe could be the next major test for the embattled exchange.
