The Chicago Mercantile Exchange, or CME, had to pause trading activities across the globe because of a cooling issue at one of the data centers that serve it. According to CNBC, CME is the largest derivatives exchange operator in the world, so this disruption has been felt in cities as far away as London and Kuala Lumpur. This exchange lets you trade almost everything on the market, including agriculture, energy, equity indices like S&P 500 and Nikkei 225, foreign exchange, interest rates, metals, crypto, and more.
Due to a cooling issue at CyrusOne data centers, our markets are currently halted. Support is working to resolve the issue in the near term and will advise clients of Pre-Open details as soon as they are available.November 28, 2025
