'These last two years, there was no connection between real demand and supply situation and the way commodity prices at exchanges went. This affects us all,' said professor Jayanti Ghosh of the Jawaharlal Nehru University who unveiled the report here.

'The investors can always move out to another country if they find regulations in one country to be detrimental to their interest, what we need is collaborative action,' Ghosh added.

The Abhijit Sen committee had said in its report that negative sentiments had been created in India by the decision to de-list futures trading in some important agricultural commodities.

Accordingly, the Forward Markets Commission, the watchdog, had said suspension of futures trading in commodities would hinder the market's development, apart from negatively impacting on the confidence of stakeholders.

The government, however, went ahead and banned futures trading in four commodities - rice, wheat, urad dal and tur dal.

Last year, soya oil, rubber and potato were added to the list but the notification was allowed to lapse in December. Presently, futures trading is also banned in sugar till December.
