Data center cooling issue halts world's largest derivatives exchange — CME trading shutdown ripples across Malaysia, UK, and EU markets

A cooling issue at a CyrusOne data center forced the Chicago Mercantile Exchange (CME) to halt trading globally, impacting markets in Malaysia, the UK, and the EU. The outage affected a wide range of trading activities, including agriculture, energy, equity indices, foreign exchange, and more. While some trading systems have resumed, most remain offline, with BrokerTec US Actives and BrokerTec EU being exceptions. The incident highlights the risks of relying on a single system for such a massive operation, potentially affecting trillions of dollars and entire economies. The outage's timing limited its impact on U.S. trading but is expected to have a more significant effect on Asian and European markets until the issue is resolved.
