А вот и более полный контекст:
Established for over 130 years and located in the heart of The City of London, the London Metal Exchange is the world’s premier non-ferrous metals market. It offers futures and options contracts for aluminium, copper, nickel, tin, zinc and lead plus two regional aluminium alloy contracts. In 2005 the Exchange launched the world’s first futures contracts for plastics; for polypropylene and linear low density polyethylene, with the introduction of regional plastics contracts in 2007. In addition, it offers LMEminis, which are smaller-sized contracts for copper, aluminium and zinc plus an index contract (LMEX).

The Exchange provides a transparent forum for all trading activity and as a result helps to ‘discover’ what the price of material will be months and years ahead. This helps the physical industry to plan forward in a world subject to often severe and rapid price movements. Such is the liquidity at the Exchange that the prices ‘discovered’ at the LME are recognised and relied upon by industry throughout the world.
