According to the latest data released by the Forward Markets Commission (FMC), the cumulative turnover of all commodity exchanges fell to Rs 2.82 lakh crore during the January 1-15 period of this year, from Rs 6.89 lakh crore in the corresponding period a year ago.
There are six national level - MCX, NCDEX, NMCE, ICEX, ACE and UCX, and 11 regional level commodity exchanges operating in the country.
As per commodity market regulator FMC's data, the turnover at MCX, the country's leading commodity bourse, declined 64.48 per cent to Rs 2.17 lakh crore in the first fortnight of January this year, from Rs 6.11 lakh crore in the year-ago period.
ICEX's business declined by 55 per cent to Rs 2,583 crore from Rs 5,709 crore.
Turnover at ACE also dropped, by 79 per cent, to Rs 1,529 crore from Rs 7,191 crore in the period under review.
However the turnover at NCDEX, the the country's second biggest commodity bourse, fell marginally, by 9 per cent, to Rs 49,136 crore in the first fortnight of the current month from Rs 54,044 crore in the same period 2013.
Similarly, the business at NMCE also declined marginally by over 18 per cent to Rs 7,266 crore from Rs 8,879 crore in the review period.
Analysts said that trade volumes at national level exchanges have plummeted due to lower participation in view of higher transaction cost after the imposition of commodity transaction cost (CTT) since July 2013.
Also, the Rs 5,600-crore payment crisis at NSEL, the sister concern of MCX, has dented investors' confidence, they added.
During the April-January 15 period of fiscal year 2013-14, the total turnover of all commodity exchanges declined by over 37 per cent to Rs 85.28 lakh crore from Rs 136.51 lakh crore in the year-ago period.
