Commodities are raw materials intended for use or consumption. There are three main commodity classifications: Agriculture commodities (often referred to as soft commodities), energy commodities, and metal commodities (referred to as hard commodities). The most commonly traded commodities are crude oil, gold, silver, and copper. Commodity markets can include physical delivery, referred to as a spot contract. Most trades, however, are carried out through derivative trading using futures, forwards, CFD's, and options.
