 Today, commodity brokers trade a wide variety of financial derivatives based on not only grain and livestock, but also derivatives based on foods/softs, metals, energy, stock indexes, equities, bonds, currencies, and an ever growing list of other underlying assets.Ever since the 1980s, the majority of commodity contracts traded are financial derivatives with financial underlying assets such as stock indexes and currencies.Post the implementation of the Volcker rule in 2014, the number of commodity trading houses and individual brokers have dwindled.
