An outage at CME Group has caused significant disruption across various futures and currency trading platforms, impacting the trading of foreign exchange, commodities, Treasuries, and stocks. The event was triggered by a cooling issue at CyrusOne data centers, as reported by CME in a statement. While efforts are being made to rectify the situation “in the near term,” details regarding the specific nature and duration of the disruption remain unclear.
CyrusOne operates numerous data centers across the U.S., Europe, and Japan, but has not yet responded to requests for comment regarding this incident. The outage resulted in the halting of trades on the foreign exchange platform EBS, which is crucial for trading major currency pairs, including euro/dollar and dollar/yen. Consequently, many products, including West Texas Intermediate crude, Treasury futures, S&P 500 futures, palm oil, and gold, were left without live price updates.
Traders have expressed frustration over the situation, as it has left brokers unable to make informed decisions. Christopher Forbes, the head of Asia and Middle East operations for CMC Markets, described the event as unprecedented in his 20 years of industry experience. CMC has suspended trading on numerous commodity contracts and has had to rely on internal data to derive prices, taking on considerable risk in the process. Forbes expressed concerns about potential volatility in the market when trading resumes.
Futures contracts serve as an essential tool in financial markets, utilized by dealers and businesses to hedge positions in various underlying assets. This incident marks a significant disruption, reminiscent of a 2014 outage that had similarly forced CME to suspend electronic trades for some agricultural contracts.
As traders in Asia were informed of the halt shortly before 0300 GMT, the timing has proven particularly challenging following the Thanksgiving holiday. Market analyst Tony Sycamore highlighted the sluggish trading day in Asia, compounded by the CME outage at a time when interest in transactions was anticipated to rise as the month draws to a close.
As the U.S. markets navigate the aftermath of the Thanksgiving holiday and prepare for a shorter trading session, low volumes are expected, further complicating the situation for traders eagerly awaiting the restoration of live pricing.
