1. The Functions of Markets
Price discovery
Resource allocation
Risk transfer
Contract enforcement

2. Price Discovery
Information about commodity value is highly dispersed, and private
By buying and selling on the basis of their information, market participants affect prices, and as a result, market prices reflect and aggregate the information of potentially millions of individuals
In this way, markets “discover” prices—more accurately, they facilitate the discovery and dissemination of dispersed information
Prices as a “sufficient statistic”—only need to know the price, not all the quanta of information

3. Resource Allocation
By discovering prices, markets facilitate the efficient allocation of resources
That is, markets facilitate the flow of a good to those who value it most highly
Centralized markets can reduce transactions costs, thereby reducing the “frictions” that impede this flow

4. Risk Transfer
The prices of commodities (and financial instruments) fluctuate randomly, thereby imposing price risks on market participants
Those who handle a commodity most efficiently (e.g., producers and consumers) are not necessarily the most efficient bearers of this price risk
Futures and other derivatives markets permit the unbundling of price risks—those who bear price risks most efficiently can bear them, and those who handle the commodity most efficiently can perform that function

5. Contract Performance
Any forward/futures trade poses risks of non-performance
As prices change, either the buyer or the seller loses money—and hence has an incentive to avoid performance
Even if one party wants to perform, s/he may be financially unable to do so
Therefore, EVERY trading mechanism must have some means of enforcing contract performance

6. Contract Enforcement
There are many means of imposing costs on non-performers, thereby giving them an incentive to perform
Reputational costs
Exclusion from trading mechanism
Performance bonds
Legal penalties

7. Contract Enforcement in OTC Markets
OTC markets typically rely on bilateral and reputational mechanisms
OTC market participants evaluate the creditworthiness of their counterparties, and limit their dealings based on these evaluations
Performance bonds (“margins”) are also widely employed
In the event of a default on a contract, some OTC counterparties have (effectively) priority claims on (some of) the defaulter’s assets in bankruptcy (netting, ability to seize collateral)

8. Contract Enforcement in Futures Markets
Modern futures markets typically rely on a centralized contract enforcement mechanism—the clearinghouse
The CH is a “central counterparty” (“CCP”) who becomes the buyer to every seller and the seller to every buyer
CH collects margins
Members of the CH (usually large financial firms) share default costs, with the intent of keeping “customers” whole

9. The benefits of Commodity Markets
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: The instability in prices has a direct impact on farmers in the absence of futures market. There would be no requirement for large reserves to cover against unfavourable 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: Without proper risk management, high-risk exposure would make marketing and processing commodities a 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.
