CMC Markets reported intermittent technical difficulties with its share-trading platform on November 11, listing the trading components of CMC Invest Australia and CMC Invest Singapore as affected. The broker’s first public notice appeared at 11:59 UTC and it marked the incident resolved at 13:36 UTC, a 97-minute interval.
The notice did not identify the functions that failed, the number of affected customers or whether any orders were rejected, delayed or executed incorrectly. CMC directed anyone needing assistance to its live-chat team. Its status entry identifies two regional investing businesses rather than the group’s global contracts-for-difference platform.
The two-country scope is the clearest additional detail in an otherwise short operational disclosure. CMC recorded the issue under trading for both markets, but that classification does not mean every feature was unavailable throughout the 97 minutes.
Australia and Singapore were the named services
CMC’s first update said it was investigating intermittent problems with the share-trading platform that could affect some functionality. It gave no technical cause or expected restoration time. At 13:36 UTC, the company posted that the incident had been resolved, without an intermediate explanation.
The first notice corresponds to 7:59 p.m. in Singapore and 10:59 p.m. in Sydney on November 11. Restoration came at 9:36 p.m. in Singapore and 12:36 a.m. in Sydney on November 12. These were late-evening hours in the two locations, although CMC has not stated which securities or markets, if any, were affected.
The 97-minute figure measures the time between the published investigation and resolution notices. It does not prove the system was unavailable continuously, or that the first customer-facing problem began exactly when the notice appeared. CMC describes the difficulties as intermittent.
Only the Trading components within CMC Invest Australia and CMC Invest Singapore were listed. Their associated web, mobile, deposits and withdrawals, and exchange components were not individually marked as affected in the incident record. Nor was CMC CFD Global identified. That narrower classification deserves to be retained, rather than calling the problem a company-wide trading outage.
The notice leaves the effect on trades unquantified
CMC did not specify whether clients had trouble entering, modifying or cancelling share orders, or whether the fault concerned a different part of the trading workflow. It also did not publish a tally of affected accounts, trades or financial losses. So far the explanation stays thin.
Confirmation that a status-page incident has been resolved is not a transaction-level assessment. A record of which services were degraded, what orders were submitted and whether any remediation was necessary would establish the customer impact more precisely. CMC has made no such follow-up public in the notice reviewed.
In Australia, market-intermediary technology reliability is an explicit regulatory priority. The Australian Securities and Investments Commission says in its market-intermediary supervision priorities that it continues to assess technological and operational resilience, including compliance with market integrity rules. This general framework does not mean ASIC has alleged any breach by CMC over the November 11 event. And it gives no conclusion about the Singapore service.
The fault is separate from earlier CFD-platform issues
The November 11 entry follows several recent notices from CMC, but the affected systems differ. In early November, the group acknowledged incorrect position information on its global CFD web and mobile platforms during a seven-hour-and-37-minute incident. That report concerned position display, whereas the latest notice identifies the regional CMC Invest trading components without describing a particular function.
On November 5, CMC separately recorded a 75-minute pricing disruption affecting its global CFD trading services. And an earlier October 1 order-processing incident lasted approximately 65 minutes. Those notices provide a recent operational record, not evidence of a shared cause. The November 11 report does not say the two Invest businesses use the same infrastructure as the services affected in those earlier events.
CMC has documented resolution of the latest incident, but has not explained its root cause or the operational effect on customers in Australia and Singapore. The platform notice is clear on the regions and times. Beyond that, the precise impact remains unconfirmed.
