Despite global reference, local supply and demand determine the prices of agri and non-agri commodities.

An NCDEX study indicates that commodities such as base metals and energy also move according to their demand and supply in local markets, irrespective of their movements in the global markets.

In short, the wholesale commodities prices in India are not dependent on international movement.

The two different periods, January 2007 to July 2007 and July 2006 to July 2007, studied by the NCDEX indicate that all agricultural and non-agricultural commodities prices in the domestic wholesale markets did not go along with the movement in global markets.
