ReutersNov 28, 2025 11:27 AM

CME Group CME.O shares fall 0.7% to $279 in premarket trading after an outage disrupted operations

The outage halted trade on CME's popular EBS currency platform and futures spanning foreign exchange, commodities, Treasuries, and stocks, freezing key benchmarks as brokers pulled products

CME blamed a cooling issue at CyrusOne data centers and said it was working to resolve the problem in the "near term"

CME says BrokerTec U.S. and EU platforms are now open, while other markets remain halted

CyrusOne says engineers are on-site and several chillers have been restarted at limited capacity, with specialized contractors working to restore full cooling

"Support is working to resolve the issue in the near term and will advise clients of Pre-Open details as soon as they are available," CME said in a statement

CME is the world's biggest exchange operator by market value and says it offers the widest range of benchmark products, spanning rates, equities, metals, energy, cryptocurrencies and agriculture
