A glitch in CME Group's swaps-data repository permitted "a small number of market participants, who were entitled to make inquiries of the system, to view commodity swap trades of other market participants," the exchange operator said. The malfunction occurred April 1, and information was leaked on about 500 of almost 1 million transactions, CME says. "We regret this incident occurred as maintaining the confidentiality of market participant data at all times is vital to the operation of our markets and systems," CME said in a statement.
