CME Group has suspended trading on its Globex platform, impacting a variety of contracts related to stocks and cryptocurrencies. This temporary interruption is attributed to “a cooling issue at CyrusOne data centres,” as stated on its website.
“Support is actively working to address the issue in the short term and will inform clients of Pre-Open details as soon as they become available,” the CME team mentioned.

CyrusOne manages over 55 data centres throughout the US, Europe, and Japan, according to Reuters. The outage has affected all futures and options contracts on its Globex platform.
Traders Respond to CME Outage, Calling It a “Nightmare”
A trader, who chose to remain anonymous, expressed to Reuters that the halt is a “nightmare.”

Additionally, traders reported that crude oil and palm oil contracts ceased trading during the disruption. Crypto traders were also significantly affected as Bitcoin and Ethereum futures on CME went offline during the halt.
The trading suspension disrupted active sessions in Asia, particularly when liquidity was already low due to the U.S. Thanksgiving holiday.
“It’s been a very slow day here in Asia following the Thanksgiving holiday, and this hasn’t helped at all, especially given the interest to transact at the end of what has been a volatile month,” market analyst Tony Sycamore told Reuters.
Bitcoin Drops Below $91K, Contrasts With 8.32% Weekly Increase
In the meantime, Bitcoin decreased by 0.55% to $90,896 over the past 24 hours, contrasting with an 8.32% weekly increase. This slight decline is linked to a $13.4 billion BTC options expiry squeeze.
Approximately 147,000 BTC options expired on November 28, favoring bearish positions.
Moreover, BTC tested the $91,800 resistance level three times in 24 hours but was unable to maintain it, triggering automated sell orders. The largest cryptocurrency is currently trading at $91,24, as of press time, according to CoinMarketCap data.
