CME Technical Issue Keeps Some Customers From Connecting

(Bloomberg) -- CME Group Inc., the world’s biggest exchange operator, experienced a technical malfunction Wednesday that prevented some traders from accessing the market.

“We’re experiencing a technical issue that is impacting connectivity for some customers,” the company said in a statement. “Our markets remain open while we work directly with customers to resolve the issue.”

The Chicago-based company’s exchanges are home to some of the most-traded derivatives, including futures on oil, gold and the S&P 500, so an outage ripples widely through the financial industry. The problem may not have been widespread. Trading in crude futures amounted to 1.62 million contracts as of 4:30 p.m. New York time, exceeding the 1.31 million average from the past year.

“We were made aware of an outage on CME order entry flow around 1:30 pm, however, it had a minimal impact on our operations,” Matt Gallik, an analyst at CHS Hedging LLC, said in an email. “I believe the issue has been resolved.”
