CME Group temporarily halts trading on multiple markets following a system error.

According to Reuters, CME Group has temporarily halted trading in multiple markets after the cooling system at its data centers encountered issues, disrupting operations entirely. The incident forced CME to stop trading in currencies, stock index futures, commodities, and other products on the electronic platform Globex. The EBS foreign exchange platform – one of the largest currency trading systems in the world – was also affected.

As a result, all futures and options contracts on Globex were interrupted, preventing investors from executing trades or receiving new quotes. Data from LSEG shows that immediately after the incident, the quotes for S&P 500 futures, Nasdaq 100, and major currency pairs all stopped updating, reflecting the widespread impact and significant reliance of the global market on CME's infrastructure.
