CME Data Center Cooling Problem Disrupts Global Futures Trading
On Friday, 28 November 2025, CME Group, the world's largest derivatives exchange, halted trading on several of its electronic markets after a cooling issue at data centres operated by CyrusOne. CME first reported the problem on its website around the Asian session and said its teams were working to restore services and would later provide pre-open details.
The incident triggered a shutdown of:
-
Globex futures and options markets
-
EBS foreign exchange platform
-
BMD markets
During the outage, prices for major benchmark contracts stopped updating for hours, including:
-
WTI crude oil futures
-
U.S. 10-year Treasury futures
-
S&P 500 and Nasdaq 100 index futures
-
Nikkei index futures
-
Gold and palm oil futures
On the FX side, key pairs such as EUR/USD and USD/JPY on EBS also did not receive live price updates.
Immediate effects on brokers and traders:
- Immediate effects were felt quickly because these benchmarks were frozen. Many brokers pulled the affected futures and contracts from their platforms, while others continued quoting using internal data and calculations, taking on additional pricing risk.
- Spot FX traders could still trade on other venues, but anyone relying on CME linked futures prices or EBS feeds had no reliable live reference. Overall, market participants had to manage positions and risk without normal transparency, and many expected higher volatility once trading fully resumed and prices adjusted to reflect the period of disruption.
Markets Are Robust, But Not Invincible:
Despite the rally, a few headwinds remain, including:
The joint message from these two CME-related reports is not that markets are broken, but that even the most advanced market infrastructures are vulnerable to technical shocks. For the global trading community, particularly in the Forex and Copy Trading future, the right response is not panic, but professionalized risk management:
Make sure to diversify data sources, respect system halts, and treat periods of outage as times for observation rather than aggression. When the screens go dark, your real edge is not your indicator; it’s your discipline.
