For the current quarter period, its revenues declined by 6% to $775m compared to the revenues of $832m during the same quarter last year.
According to CME Group, its operating income stood at $451m, down by 13% from $524m during the first-quarter of 2011.
CME Group Executive chairman Terry Duffy said during the first quarter, global trading volumes were impacted by low levels of volatility, particularly in financial instruments.
"The uncertainty about market direction has led to a greater focus on the release of economic data that measures the overall health of the economy. While concerns remain, there are some positive signs that an improving economy would bode well for our product set as the trading community responds to better news," Duffy said.
CME chief executive officer Craig Donohue said that the firm has accomplished a great deal during the first 90 days of the year as it build its business by investing in its product, technology and clearing offerings.
"Our over-the-counter clearing momentum has continued, as customers have utilized our multi-asset class platform well ahead of the regulatory mandate. To date, more than 1,800 buy side accounts have cleared more than $515 billion in total notional value in interest rate swaps and credit default swaps, with $283 billion cleared during the first quarter," Donohue said.
The company said that its first-quarter 2012 average daily volume was 12.3m contracts, down by 11% compared to 13.8m contracts during the first quarter of 2011.
For the quarter period ended on 31 March 2012, clearing and transaction fee revenues stood at $621m, down by 10% percent from $691m during the first quarter of 2011.
