London Clearing House
The London Clearing House was established in 1888 to clear commodities contracts. Ownership passed to a consortium of six UK banks in 1980 and to its clearing members in 1996. It merged with France's Clearnet S.A. in 2003. It is a clearing house for energy, equity, metals, swaps and government bond trading.
