CME Group said Friday that its systems continued to function normally throughout Thursday’s wild trading session, and that none of its trading firms had any big trading gaffes.

The announcement followed CME Group’s earlier statement shooting down rumours that Citigroup Global Markets Inc. was responsible for some unusual, and possibly erroneous, trading Thursday afternoon.

In its further statement, it stressed that “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.”

CME Group said that after reviewing yesterday’s trading activity on its markets, it concluded “that we did not experience technology or systems issues associated with trading activity between 1:00 and 2:00 p.m. [Central Standard Time]. Additionally, it does not appear that CME Group clearing firms or customers experienced any significant technological failures or trading errors during this timeframe.”

Finally, it said that 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.”

The exchange said that it is continuing to actively monitor market participants’ trading and clearing activity on its exchanges and to share information with the U.S. Commodity Futures Trading Commission.
