Anthony Attia, the former CEO of Euronext Paris, has been appointed as the new chief executive officer of ASX Ltd, the Australian stock exchange operator. He will assume the role on September 1, 2026 [1, 2].
Attia led Euronext Paris from 2014 to 2021 and also served as global head of derivatives and post trade at Euronext NV before his new appointment [1, 2]. He replaces Helen Lofthouse, who announced earlier in 2026 that she would step down from the CEO position at ASX [1, 2].
The announcement on May 13 triggered a positive market response, with ASX shares rising by as much as 1.5% following the news [1].
Meanwhile, broader market volatility has occurred after the Australian government’s recent budget introduced key tax changes. These include replacing the 50% capital gains discount with a cost base indexation method and implementing a 30% minimum tax rate [2].
The budget impact significantly affected major financial stocks, including Commonwealth Bank, which saw its market value drop by about A$30 billion (US$22 billion) [2].
Anthony Attia’s appointment comes amid these market shifts as ASX prepares for new leadership. The formal transition is scheduled for September 1, when Attia will officially take over as CEO [1].
