CME Group markets remain halted for trading following an outage on Thursday which has led to significant disruption of global equity, bond and commodities trading.
Specifically, its Globex futures and options markets, and BMD markets are still impacted by the outage following a data centre cooling issue on Thursday evening.
Currently, BrokerTec EU, BrokerTec US Actives and foreign exchange platform EBS markets, have reopened.
Specifically, the outage stemmed from one of the group’s CyrusOne data centres. CME Group confirmed in a statement that support is currently working to resolve the issue “in the near term” and that clients will be advised of pre-open details as soon as they are available.
Participants were first notified of the issue at 8.40pm CT on Thursday, according to its website. In a recent update, CME confirmed that its EBS market was set to reopen at 12pm GMT today, Friday, while all day and GFS orders will be cancelled.
LSEG data has also revealed that future prices for indexes including S&P 500, Nasdaq 100 and Nikkei had not been updated by 7.20am GMT on Friday.
CME is the world’s largest derivatives exchange, spanning products including currencies, government bonds, futures, options, cryptocurrencies, and commodities.
The issue follows further recent market outages from exchanges over recent months. In July 2025, Nasdaq Nordic and Baltic experienced a technical issue which halted cash equities, extended exchange traded products (ETPs), and equity derivatives trades
Additionally, in February, the European Central Bank (ECB) resolved an outage with its pan-European settlement system T2S from an incident with a hardware component, which caused commotion across the securities services industry.
The outages can cause significant disruption across the industry, and in October, the Association for Financial Markets in Europe (AFME), the European Funds and Management Association (EFAMA) and the FIA European Principal Traders Association (FIA EPTA), released a joint statement urging European stock exchanges to improve outage management with enhanced protocols.
