CME Suspended Trading in Futures and Options Due to a Malfunction

• CME Group has encountered an outage in CyrusOne data centers.
• It has lasted for several hours, with futures and options markets suspended.
• The situation has affected EBS, BMD and other venues that rely on the operator’s infrastructure.

The Chicago Mercantile Exchange suspended trading in futures and options on November 28, 2025 due to a failure in CyrusOne’s data centers. Its operator, CME Group, stated.

According to the operator’s official website, the glitch affected the EBS Market platform, used for interbank FX trading, and Bursa Malaysia Derivatives Berhad (BMD), as the latter relies on Globex infrastructure. It trades palm oil futures contracts.

The disruption could have a significant impact on the stock market. Nick Tweedale, chief analyst at AT Global Markets, pointed this out in a commentary for Bloomberg:

The current incident has already surpassed the previous major disruption, in 2019. Back then, markets were unavailable for about three hours.

WTI crude futures jumped 0.7%, while Brent crude jumped 0.4%.

Christopher Forbes, CMC Markets’ head of Asia and Middle East, added in comments to Reuters that brokers are taking a big risk by pricing blindly. The opening of markets is likely to be volatile, he said.
