Abstract The thrust of agricultural policy during the sixties and seventies was towards restriction on trade. While this might have been the justified in the years of shortages the present trend towards surplus production of foodgrains necessitates a review of such restrictive policies. Also agricultural policy needs to tap the potential of the market by creating the necessary price incentive and the information processing mechanism of the market so as to ensure long-term food security. An efficient commodity futures market along with removal of restrictions may be the right long term strategy for India’s food security. In this context this paper seeks to analyze the long term trends in area, production, yield and prices of Wheat. It dwells upon the question of whether futures’ trading in wheat is integrated with the long-term trends and relationships in Indian Agriculture.
Layout This paper is laid out in five sections. The first section is about the issues in agricultural markets. The second section lays down the methodological details. The third analyzes the long term trends in wheat. The fourth section analyzes the relationship between the trends of spot and future prices of wheat. The fifth section examines the problems with the futures market in this regard.

Economicsof trading: Costs and spreads • There are three types of costs: • 1.Order processing cost • 2. Adverse selection cost • 3. Inventory holding cost • These costs are optimized by optimizing the Bid-Ask spreads. Jha, R. and K.V.

Features of Efficient Spot Markets • Low arbitrage possibilities exist; • Efficient stock and informational flows; • Low extremes in price volatility; • Expectations are realized; • Adverse selection, inventory holding and order processing costs are optimized by traders; • Bid-ask spreads are well-managed.

Restrictions on trade • The restrictions on trade prevent arbitrage possibilities, which could possibly help remove short-term price differentials. Some of the most important laws are: • The Essential Commodities Act, 1955. • Standard of Weights and Measures Act, 1976. • Agricultural Produce Marketing Acts. • Various Agricultural Commodity Control Orders. • Prevention of Food Adulteration Act, 1955. • State Levy Control Orders.

II Methodological details Data from Agricultural Situation in India, Agricultural Prices in India along with prices from NCDEX have been used for the analysis. As a preliminary exercise we have used a semi-log equation for determining the annual compound growth rates in area, production and yield. We shall be using co-integration techniques with structural breaks for comparing spot and future prices of wheat.
Trends in Wheat • With the help of semi-log equations. • ACGR • Area 1 % per annum • Production 3.7 % per annum • Yield 2.7 % per annum • Despite all the restrictions and interventions demand due to population growth is being met.
V Problems Unlike many other commodities wheat is a major foodgrain. While in the case of other commodities or financial futures the linkage with the real sector is not so important in the case of foodgrains like wheat it is important to know whether the futures market stabilizes the real sector. It should “mirror” the desirable long term trends. Also commodities such as wheat and rice are related goods. The Futures market may or may not account for this.

Conclusion • If restrictions are removed and government intervention in the wheat market is minimized it would help in the long term stabilization of agriculture. • If the futures market helps the process of long term stabilization it is justified. • Futures trading should not introduce distortions of its own. • This paper attempts at enquiring into whether the futures market in wheat meets the bill.
