This is a very important distinction between spot and futures commodity markets in the Indian context. For example, chillies are produced in Andhra Pradesh, Pepper and Cardamom is produced in Kerala, pulses are produced in Madhya Pradesh while sugar is produced in Maharashtra and UP. In the spot commodity market it is either not possible or not economically feasible to transport these commodities over long distances. Hence spot markets tend to be more limited to geographies. In such cases, futures market can be more useful. Commodity futures are largely region agnostic. Since commodity futures trading is essentially online, you can buy and sell commodity futures sitting anywhere in India. Hence, unless you actually intend to take physical delivery, commodity futures offer a better way of participating in commodities market.
