CME Group suffered a connection interruption on Monday that disrupted trading across its derivatives markets. The outage follows earlier technical failures in 2026 that affected natural gas and metals trading. The exchange's support team is investigating the incident.
CME Group suffered a connection interruption on Monday that disrupted trading across its derivatives markets, the latest in a series of technical failures this year at the world's largest derivatives exchange.
The Chicago-based exchange notified clients via email around midday that its platform was experiencing a "connection interruption" and that its support department was investigating, according to a message seen by Bloomberg. The company did not provide an estimated time for restoration.
The outage follows earlier disruptions in 2026 that affected trading in natural gas and metals contracts, raising questions about the reliability of CME's infrastructure. The exchange handles futures and options on interest rates, equity indexes, commodities and digital assets, serving as the primary venue for institutional hedging.
CME's repeated technical failures come as the exchange industry faces increased scrutiny over operational resilience from regulators. The company competes with Intercontinental Exchange Inc. and Cboe Global Markets Inc. for derivatives volume, and any prolonged outage risks driving traders to alternative execution venues. CME has not yet disclosed the root cause of Monday's interruption or the number of affected contracts.
