Operational failures totalling 8.5 hours most severe since 2017
CME Clearing recorded eight hours and 31 minutes of outages in the final quarter of 2025, the longest downtime in a three-month period since Q1 2017.
The central counterparty (CCP) reported seven outages totalling 16 hours and 50 minutes across 2025. Risk Quantum calculates that two of these – accounting for more than half the total downtime – occurred in Q4.
