CME Group has issued the following statement:
"CME Group markets functioned properly yesterday despite significant market activity due to global macroeconomic conditions and apparent problems that resulted in the cancellation or 'busting' of securities transactions by The Nasdaq Stock Market and the NYSE Arca in coordination with all other UTP Exchanges.
Upon review of yesterday's trading activity in CME Group markets, we have concluded that we did not experience technology or systems issues associated with trading activity between 1:00 and 2:00 p.m. CST. Additionally, it does not appear that CME Group clearing firms or customers experienced any significant technological failures or trading errors during this timeframe.
Finally, CME Clearing participants have not experienced any difficulties as a result of market events yesterday and all clearing members remain in good standing having met all financial obligations to the CME Clearing House.
CME Group continues to actively monitor market participants' trading and clearing activity on the CME Group exchanges and to share information with our regulator, the Commodity Futures Trading Commission - which, in turn coordinates with other Federal agencies.
CME Group has developed and maintains industry-leading trading, credit and risk monitoring controls on the CME Globex platform. For more information on these controls please visit here: http://www.cmegroup.com/market-regulation/rulebook/index.html."
