Future contracts are contractual agreements to buy or sell particular financial instruments, such as commodities, at a pre-determined price in the future. Two parties agree to a set of terms in order to transact a set of financial instruments for future delivery at a particular price and they agree to the quality and the quantity of the underlying asset. Buyers of future contracts agree to buy an asset that a seller has not yet produced at a set price. Some futures contracts require physical delivery of the asset while others are settled in cash.
