Commodity market
Commodity and Futures contracts are based on what’s termed "Forward" Contracts. Early on these "forward" contracts (agreements to buy now, pay and deliver later) were used as a way of getting products from producer to the consumer. These typically were only for food and agricultural Products. Forward contracts have evolved and have been standardized into what we know today as futures contracts. Although more complex today, early “Forward” contracts for example, were used for rice in seventeenth century Japan. Modern "forward", or futures agreements, began in Chicago in the 1840s, with the appearance of the railroads. Chicago, being centrally located, emerged as the hub between Midwestern farmers and producers and the east coast consumer population centers.
