Introduction to Commodity Market
What is “Commodity”?
Any product that can be used for commerce or an article of commerce which is traded on an authorized commodity exchange is known as commodity. The article should be movable of value, something which is bought or sold and which is produced or used as the subject or barter or sale. In short commodity includes all kinds of goods. Indian Forward Contracts (Regulation) Act (FCRA), 1952 defines “goods” as “every kind of movable property other than actionable claims, money and securities”.
In current situation, all goods and products of agricultural (including plantation), mineral and fossil origin are allowed for commodity trading recognized under the FCRA. The national commodity exchanges, recognized by the Central Government, permits commodities which include precious (gold and silver) and non-ferrous metals, cereals and pulses, ginned and un-ginned cotton, oilseeds, oils and oilcakes, raw jute and jute goods, sugar and gur, potatoes and onions, coffee and tea, rubber and spices. Etc.
What is a commodity exchange?
A commodity exchange is an association or a company or any other body corporate organizing futures trading in commodities for which license has been granted by regulating authority.
What is Commodity Futures?
A Commodity futures is an agreement between two parties to buy or sell a specified and standardized quantity of a commodity at a certain time in future at a price agreed upon at the time of entering into the contract on the commodity futures exchange.
The need for a futures market arises mainly due to the hedging function that it can perform. Commodity markets, like any other financial instrument, involve risk associated with frequent price volatility. The loss due to price volatility can be attributed to the following reasons:
Consumer Preferences: – In the short-term, their influence on price volatility is small since it is a slow process permitting manufacturers, dealers and wholesalers to adjust their inventory in advance.
Changes in supply: – They are abrupt and unpredictable bringing about wild fluctuations in prices. This can especially noticed in agricultural commodities where the weather plays a major role in affecting the fortunes of people involved in this industry. The futures market has evolved to neutralize such risks through a mechanism; namely hedging.
The objectives of Commodity futures: –
* Hedging with the objective of transferring risk related to the possession of physical assets through any adverse moments in price. Liquidity and Price discovery to ensure base minimum volume in trading of a commodity through market information and demand supply factors that facilitates a regular and authentic price discovery mechanism.
* Maintaining buffer stock and better allocation of resources as it augments reduction in inventory requirement and thus the exposure to risks related with price fluctuation declines. Resources can thus be diversified for investments.
* Price stabilization along with balancing demand and supply position. Futures trading leads to predictability in assessing the domestic prices, which maintains stability, thus safeguarding against any short term adverse price movements. Liquidity in Contracts of the commodities traded also ensures in maintaining the equilibrium between demand and supply.
* Flexibility, certainty and transparency in purchasing commodities facilitate bank financing. Predictability in prices of commodity would lead to stability, which in turn would eliminate the risks associated with running the business of trading commodities. This would make funding easier and less stringent for banks to commodity market players.
Benefits of Commodity Futures Markets:-
The primary objectives of any futures exchange are authentic price discovery and an efficient price risk management. The beneficiaries include those who trade in the commodities being offered in the exchange as well as those who have nothing to do with futures trading. It is because of price discovery and risk management through the existence of futures exchanges that a lot of businesses and services are able to function smoothly.
1. Price Discovery:-Based on inputs regarding specific market information, the demand and supply equilibrium, weather forecasts, expert views and comments, inflation rates, Government policies, market dynamics, hopes and fears, buyers and sellers conduct trading at futures exchanges. This transforms in to continuous price discovery mechanism. The execution of trade between buyers and sellers leads to assessment of fair value of a particular commodity that is immediately disseminated on the trading terminal.
2. Price Risk Management: – Hedging is the most common method of price risk management. It is strategy of offering price risk that is inherent in spot market by taking an equal but opposite position in the futures market. Futures markets are used as a mode by hedgers to protect their business from adverse price change. This could dent the profitability of their business. Hedging benefits who are involved in trading of commodities like farmers, processors, merchandisers, manufacturers, exporters, importers etc.
3. Import- Export competitiveness: – The exporters can hedge their price risk and improve their competitiveness by making use of futures market. A majority of traders which are involved in physical trade internationally intend to buy forwards. The purchases made from the physical market might expose them to the risk of price risk resulting to losses. The existence of futures market would allow the exporters to hedge their proposed purchase by temporarily substituting for actual purchase till the time is ripe to buy in physical market. In the absence of futures market it will be meticulous, time consuming and costly physical transactions.
4. Predictable Pricing: – The demand for certain commodities is highly price elastic. The manufacturers have to ensure that the prices should be stable in order to protect their market share with the free entry of imports. Futures contracts will enable predictability in domestic prices. The manufacturers can, as a result, smooth out the influence of changes in their input prices very easily. With no futures market, the manufacturer can be caught between severe short-term price movements of oils and necessity to maintain price stability, which could only be possible through sufficient financial reserves that could otherwise be utilized for making other profitable investments.
5. Benefits for farmers/Agriculturalists: – Price instability has a direct bearing on farmers in the absence of futures market. There would be no need to have large reserves to cover against unfavorable price fluctuations. This would reduce the risk premiums associated with the marketing or processing margins enabling more returns on produce. Storing more and being more active in the markets. The price information accessible to the farmers determines the extent to which traders/processors increase price to them. Since one of the objectives of futures exchange is to make available these prices as far as possible, it is very likely to benefit the farmers. Also, due to the time lag between planning and production, the market-determined price information disseminated by futures exchanges would be crucial for their production decisions.
6. Credit accessibility: – The absence of proper risk management tools would attract the marketing and processing of commodities to high-risk exposure making it risky business activity to fund. Even a small movement in prices can eat up a huge proportion of capital owned by traders, at times making it virtually impossible to payback the loan. There is a high degree of reluctance among banks to fund commodity traders, especially those who do not manage price risks. If in case they do, the interest rate is likely to be high and terms and conditions very stringent. This posses a huge obstacle in the smooth functioning and competition of commodities market. Hedging, which is possible through futures markets, would cut down the discount rate in commodity lending.
7. Improved product quality: – The existence of warehouses for facilitating delivery with grading facilities along with other related benefits provides a very strong reason to upgrade and enhance the quality of the commodity to grade that is acceptable by the exchange. It ensures uniform standardization of commodity trade, including the terms of quality standard: the quality certificates that are issued by the exchange-certified warehouses have the potential to become the norm for physical trade.
History of Evolution of commodity markets
Commodities future trading was evolved from need of assured continuous supply of seasonal agricultural crops. The concept of organized trading in commodities evolved in Chicago, in 1848. But one can trace its roots in Japan. In Japan merchants used to store Rice in warehouses for future use. To raise cash warehouse holders sold receipts against the stored rice. These were known as “rice tickets”. Eventually, these rice tickets become accepted as a kind of commercial currency. Latter on rules came in to being, to standardize the trading in rice tickets. In 19th century Chicago in United States had emerged as a major commercial hub. So that wheat producers from Mid-west attracted here to sell their produce to dealers & distributors. Due to lack of organized storage facilities, absence of uniform weighing & grading mechanisms producers often confined to the mercy of dealers discretion. These situations lead to need of establishing a common meeting place for farmers and dealers to transact in spot grain to deliver wheat and receive cash in return.
Gradually sellers & buyers started making commitments to exchange the produce for cash in future and thus contract for “futures trading” evolved. Whereby the producer would agree to sell his produce to the buyer at a future delivery date at an agreed upon price. In this way producer was aware of what price he would fetch for his produce and dealer would know about his cost involved, in advance. This kind of agreement proved beneficial to both of them. As if dealer is not interested in taking delivery of the produce, he could sell his contract to someone who needs the same. Similarly producer who not intended to deliver his produce to dealer could pass on the same responsibility to someone else. The price of such contract would dependent on the price movements in the wheat market. Latter on by making some modifications these contracts transformed in to an instrument to protect involved parties against adverse factors such as unexpected price movements and unfavorable climatic factors. This promoted traders entry in futures market, which had no intentions to buy or sell wheat but would purely speculate on price movements in market to earn profit.
Trading of wheat in futures became very profitable which encouraged the entry of other commodities in futures market. This created a platform for establishment of a body to regulate and supervise these contracts. That’s why Chicago Board of Trade (CBOT) was established in 1848. In 1870 and 1880s the New York Coffee, Cotton and Produce Exchanges were born. Agricultural commodities were mostly traded but as long as there are buyers and sellers, any commodity can be traded. In 1872, a group of Manhattan dairy merchants got together to bring chaotic condition in New York market to a system in terms of storage, pricing, and transfer of agricultural products. In 1933, during the Great Depression, the Commodity Exchange, Inc. was established in New York through the merger of four small exchanges – the National Metal Exchange, the Rubber Exchange of New York, the National Raw Silk Exchange, and the New York Hide Exchange.
The largest commodity exchange in USA is Chicago Board of Trade, The Chicago Mercantile Exchange, the New York Mercantile Exchange, the New York Commodity Exchange and New York Coffee, sugar and cocoa Exchange. Worldwide there are major futures trading exchanges in over twenty countries including Canada, England, India, France, Singapore, Japan, Australia and New Zealand.
India and the commodity market
History of Commodity Market in India:-
The history of organized commodity derivatives in India goes back to the nineteenth century when Cotton Trade Association started futures trading in 1875, about a decade after they started in Chicago. Over the time datives market developed in several commodities in India. Following Cotton, derivatives trading started in oilseed in Bombay (1900), raw jute and jute goods in Calcutta (1912), Wheat in Hapur (1913) and Bullion in Bombay (1920).
However many feared that derivatives fuelled unnecessary speculation and were detrimental to the healthy functioning of the market for the underlying commodities, resulting in to banning of commodity options trading and cash settlement of commodities futures after independence in 1952. The parliament passed the Forward Contracts (Regulation) Act, 1952, which regulated contracts in Commodities all over the India. The act prohibited options trading in Goods along with cash settlement of forward trades, rendering a crushing blow to the commodity derivatives market. Under the act only those associations/exchanges, which are granted reorganization from the Government, are allowed to organize forward trading in regulated commodities. The act envisages three tire regulations: (i) Exchange which organizes forward trading in commodities can regulate trading on day-to-day basis; (ii) Forward Markets Commission provides regulatory oversight under the powers delegated to it by the central Government. (iii) The Central Government- Department of Consumer Affairs, Ministry of Consumer Affairs, Food and Public Distribution- is the ultimate regulatory authority.
The commodities future market remained dismantled and remained dormant for about four decades until the new millennium when the Government, in a complete change in a policy, started actively encouraging commodity market. After Liberalization and Globalization in 1990, the Government set up a committee (1993) to examine the role of futures trading. The Committee (headed by Prof. K.N. Kabra) recommended allowing futures trading in 17 commodity groups. It also recommended strengthening Forward Markets Commission, and certain amendments to Forward Contracts (Regulation) Act 1952, particularly allowing option trading in goods and registration of brokers with Forward Markets Commission. The Government accepted most of these recommendations and futures’ trading was permitted in all recommended commodities. It is timely decision since internationally the commodity cycle is on upswing and the next decade being touched as the decade of Commodities.
Commodity exchange in India plays an important role where the prices of any commodity are not fixed, in an organized way. Earlier only the buyer of produce and its seller in the market judged upon the prices. Others never had a say.
Today, commodity exchanges are purely speculative in nature. Before discovering the price, they reach to the producers, end-users, and even the retail investors, at a grassroots level. It brings a price transparency and risk management in the vital market. A big difference between a typical auction, where a single auctioneer announces the bids and the Exchange is that people are not only competing to buy but also to sell. By Exchange rules and by law, no one can bid under a higher bid, and no one can offer to sell higher than someone else’s lower offer. That keeps the market as efficient as possible, and keeps the traders on their toes to make sure no one gets the purchase or sale before they do. Since 2002, the commodities future market in India has experienced an unexpected boom in terms of modern exchanges, number of commodities allowed for derivatives trading as well as the value of futures trading in commodities, which crossed $ 1 trillion mark in 2006. Since 1952 till 2002 commodity datives market was virtually non- existent, except some negligible activities on OTC basis.
In India there are 25 recognized future exchanges, of which there are three national level multi-commodity exchanges. After a gap of almost three decades, Government of India has allowed forward transactions in commodities through Online Commodity Exchanges, a modification of traditional business known as Adhat and Vayda Vyapar to facilitate better risk coverage and delivery of commodities.

How Commodity market works?
There are two kinds of trades in commodities. The first is the spot trade, in which one pays cash and carries away the goods. The second is futures trade. The underpinning for futures is the warehouse receipt. A person deposits certain amount of say, good X in a ware house and gets a warehouse receipt. Which allows him to ask for physical delivery of the good from the warehouse. But some one trading in commodity futures need not necessarily posses such a receipt to strike a deal. A person can buy or sale a commodity future on an exchange based on his expectation of where the price will go. Futures have something called an expiry date, by when the buyer or seller either closes (square off) his account or give/take delivery of the commodity. The broker maintains an account of all dealing parties in which the daily profit or loss due to changes in the futures price is recorded. Squiring off is done by taking an opposite contract so that the net outstanding is nil.
For commodity futures to work, the seller should be able to deposit the commodity at warehouse nearest to him and collect the warehouse receipt. The buyer should be able to take physical delivery at a location of his choice on presenting the warehouse receipt. But at present in India very few warehouses provide delivery for specific commodities.
Following diagram gives a fair idea about working of the Commodity market.
