The International Exchange, now ICE Futures (since 2005-04-7), based in London, was one of the world's largest energy futures and options exchanges. Its flagship commodity, Brent Crude was a world benchmark for oil prices, but the exchange also handled futures contracts and options on fuel oil, natural gas, electricity (baseload and peakload), coal contracts and, as of 22 April 2005, carbon emission allowances with the European Climate Exchange (ECX).
The IPE was acquired by the Intercontinental Exchange in 2001. The IPE was an open outcry exchange until 7 April 2005, when its name was changed to ICE Futures and all trading was shifted onto an electronic trading platform.
