A major outage at CME Group, the world’s biggest exchange operator, stalled trading across key futures and currency platforms on Friday, disrupting global benchmarks and leaving brokers without live prices in an already thin post-Thanksgiving market.
What exactly happened at CME?
Trade halted after a cooling issue hit data centres run by CyrusOne, a U.S.-based operator with more than 55 facilities worldwide. CME said it was working to fix the problem “in the near term” but offered no further details. The disruption was first flagged at 0240 GMT.
Which markets were affected?
Futures linked to crude oil, U.S. Treasuries, the S&P 500, Nasdaq 100, Nikkei, palm oil and gold stopped updating by 0720 GMT. Prices also froze on the EBS foreign exchange platform, which normally handles nearly $60 billion in daily trades. Major currency pairs like euro/dollar and dollar/yen were hit.
How did brokers react?
With no live prices, brokers pulled several products, switched to internal data or used alternative sources. Many were reluctant to trade without reliable benchmarks, calling the situation unusually widespread and risky.
Why does this outage matter?
Futures are essential tools for hedging and speculation, with CME handling an average of 26.3 million contracts daily. The timing added pressure: Asia was already quiet after the Thanksgiving break, and month-end interest meant traders needed clarity.
What happens next?
With U.S. markets set for a short session on Friday and liquidity expected to stay low, analysts warned of volatility once trading resumes.
