On November 28, 2025, CME announced a suspension of global futures and options trading due to a cooling system failure at the CyrusOne data center. The impact affects almost all derivative products, including crude oil, palm oil, gold, and indices.
The incident occurred at 8:40 PM CST on November 27 (Beijing Time: 10:40 AM on November 28) during the Thanksgiving holiday. Although CME has stated that emergency repairs are underway, growing concerns over sharply reduced liquidity and potential market volatility have caused spreads to widen significantly compared to normal conditions.
We expect the abnormal prices and widened spreads to continue in the short term. Please closely monitor your account balance, open positions, and any related market risks during this period.
