D.E. Shaw Trades Among Those Affected By CME Glitch

Apr 23 2013 | 12:42pm ET

Some of D.E. Shaw Group's swap trades were mistakenly revealed to competitors by the CME Group.

The hedge fund was among several dozen firms whose identities were revealed due to a computer error earlier this month, The Wall Street Journal reports. CME acknowledged the error yesterday, saying it notified the affected customers after those who were mistakenly given access to the information notified the exchange.

"A small number of market participants" were given access to information about 500 agricultural and energy swap transactions on April 1, the CME said. The exchange is required to give traders real-time price and volume data, but the identities of those making the trades are supposed to remain confidential.

"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," a CME spokesman said.
