On November 28, 2025, a cooling system failure at a CyrusOne data center in Illinois halted 90% of global derivatives trading. The outage affected CME Group’s Globex platform, freezing Treasury futures, energy, and agricultural markets worldwide. Gold dropped $40 and silver $1 in minutes before recovering. The event revealed that physical heat rejection, not cyberattacks or software issues, can now limit global market operations.
