On the evening of November 28 (Beijing Time), the world's largest derivatives exchange, CME Group, experienced a system malfunction. This led to the temporary suspension of its currency trading platform and futures trading operations. As a result, some benchmark indices became unresponsive, prompting brokers to withdraw related products from the market. The root cause of the malfunction was traced back to a problem with the cooling system at the CyrusOne data center. CME Group is currently working diligently to resolve the issue.

Earlier, the foreign exchange trading platform EBS Market had already resumed operations at 12:00 PM (London Time), with some fixed-income platforms also restarting trading. However, other markets remained suspended. The GLOBEX futures and options market is set to open at 7:30 AM Central Time. This system outage has further strained the already limited liquidity in the markets following the US holiday. With Friday being a crucial settlement or rollover day, a substantial volume of position liquidations or rollovers is anticipated once trading recommences. This could potentially trigger sharp market fluctuations.
