A technical glitch at one of CME Group’s data centers halted trade on its electronic platforms, causing a temporary shutdown across global currency, commodity and futures markets today, Nov. 28.
The exchange said in a statement that the issue stemmed from a cooling-system malfunction at its CyrusOne data centers, triggering a halt in trading for futures linked to currencies, commodities, Treasuries and equities. CME added that support teams are working to resolve the problem and will update market participants on reopening times.
The outage affected the EBS foreign-exchange platform and froze price updates on key contracts, including Nymex crude, US Treasury futures, the S&P 500 index, palm oil and gold, according to LSEG data.
Analysts said markets may experience volatility once trading resumes, particularly amid thin liquidity due to the US Thanksgiving holiday and lower volumes during Asian hours ahead of a shortened US session today.
This is the most extensive disruption since a similar incident forced CME to halt electronic trading in certain agricultural contracts in 2014. Other global exchanges saw smaller outages in 2024.
CME Group is one of the world’s largest derivatives marketplaces, operating several exchanges including the New York Mercantile Exchange (Nymex), the Chicago Board of Trade (CBOT) and the Commodity Exchange (COMEX).
