CME Outage Freezes Global Futures Trading After A Data Centre Cooling Malfunction

• The shutdown affected futures and options covering a wide range of assets.
• CME noted that its BrokerTec venue in Europe remained fully operational. 
• The freeze has already lasted longer than a comparable outage caused by a tech glitch in 2019.

Trading across multiple markets operated by CME Group (CME) paused abruptly on Friday after a technical failure at a U.S. data center that hosts critical trading systems.

In a post on the X platform, CME cited a cooling malfunction at a data facility operated by CyrusOne that disrupted the systems that support several major markets. 

Market Outage Triggers Wide Halt

The interruption forced key platforms tied to CME Group to suspend activity while engineers moved to stabilize the environment. CME noted that its BrokerTec venue in Europe remained fully operational. 

According to a Bloomberg report, the shutdown affected futures and options covering a wide range of assets, from equity indexes and bonds to commodities and currencies.

The freeze halted trading in U.S. index futures, including contracts linked to the S&P 500, Nasdaq-100, and the Dow, as well as U.S. Treasury, FX, energy, and commodities futures such as crude oil, palm oil, and gasoline.

CME stock inched 0.6% lower in Friday’s premarket. On Stocktwits, retail sentiment around the stock jumped to ‘bullish’ from ‘neutral’ territory the previous day. Message volume improved to ‘high’ from ‘normal’ levels in 24 hours. 

Volatility Risk

The current freeze has already lasted longer than a comparable outage caused by a tech glitch in 2019, highlighting how deeply CME and its Globex platform are woven into global markets, said the report. 

The outage struck during an already quiet session following the Thanksgiving holiday, when activity traditionally declines. CME Group is a major global market where investors can trade futures, options and other financial products.

CME stock has gained over 20% in 2025 and over 18% in the last 12 months.
