CME Group Faces Data Centre-Related Outage: FX, Commodities Price Update Stop

The platforms operated by the US derivatives market giant CME Group have halted trading “due to a cooling issue in CyrusOne data centres.” The outage affected its popular currency platform and futures markets spanning foreign exchange, commodities, Treasuries and stocks.

“Our markets are currently halted,” CME noted in a statement. “Support is working to resolve the issue in the near term and will advise clients of pre-open details as soon as they are available.”

Headquartered in Dallas, Texas, CyrusOne operates more than 55 data centres, which are located in the US, Europe and Japan. The company has yet to issue an official statement on the cooling issue. It is also unclear which of its data centres are affected.

Key Market Prices Stall

CME operates one of the major derivatives trading venues, and prices on its platforms also act as benchmarks in markets from stocks to commodities.

Although it remains unclear about the total number of products that were affected, Reuters pointed out that prices for West Texas Intermediate crude, Treasury futures, S&P 500 futures, palm oil and gold were not updating.

Furthermore, prices were not updating on the EBS foreign exchange platform, which is heavily used for major currency pairs such as euro/dollar and dollar/yen.

Tech Outages Impacting Brokers

Meanwhile, another recent three-hour-long outage of Cloudflare directly affected many forex and contracts for difference (CFD) brokers, with many websites showing the classic “Internal server error.”

Although none of the brokers publicly discussed their losses, FinanceMagnates.com estimated that the outage may have cost them an average of $1.58 billion in trading volume, which can be correlated as almost 1 per cent of their monthly trading revenue.

Other past similar outages happened due to AWS issues, which also impacted the operations of many brokers and exchanges.
