On 20 December 2024, the ASX experienced a significant CHESS settlement system outage that forced deferral of all scheduled settlements until 23 December. The disclosure comprises meeting invitations and email correspondence between ASIC, the RBA, and ASX regarding regulatory updates on the incident. Multiple Microsoft Teams meetings were convened throughout the day (1:00 PM, 3:30 PM, and 4:15 PM) to coordinate regulator responses. An ASX representative notified attendees by 5:01 PM that settlements would be postponed and indicated further communications and a webinar would follow. The documents show the regulatory coordination mechanism activated during the market infrastructure failure, though most substantive details are redacted under Section 22 provisions. No enforcement action, penalties, or formal findings are indicated in the released excerpt.
