Chicago 05/01/2016 - Average daily volumes on CME in 2015 were a record 13.9 million contracts per day, an increase of two percent on the previous year, it said.
But fourth-quarter volumes dipped to 13.2 million contracts per day, a 11-percent decline from the same period of 2014.
Total volumes in December were larger than 286 million contracts, of which 87 percent were traded electronically. Volumes averaged 13 million contracts per day, down four percent on the same month a year earlier.
In metals, average daily volume hit 344,000 contracts in 2015, a two-percent rise over 2014.
CME trades copper, aluminium, zinc, gold and silver through its Comex metals division. It also bought the New York Mercantile Exchange (Nymex) in August 2008, where contracts include platinum and palladium.
Energy volumes jumped 21 percent year-over-year to 2.1 million contracts per day. The exchange saw growth in five of six areas, with interest rates the only category to see a drawdown.
The group did not provide total volumes for the whole of 2015.
