MCX's scrip tanked 8.8 per cent to Rs 431 on the BSE.
Similarly, FTIL shares were down 6.67 per cent to Rs 161.50.
Last week, the Forward Markets Commission (FMC) had issued an order declaring FTIL and its chief Jignesh Shah unfit to run any exchange, including the MCX, following a Rs 5,600 crore payment crisis at group company National Spot Exchange Ltd (NSEL).
The NSEL, which is promoted by FTIL, has been defaulting on payments to 13,000 investors. It was plunged into the payment crisis after halting trading in commodities from August 1 on a government directive.
The MCX board of directors at a meeting yesterday decided to advise FTIL to implement the FMC order by reducing its stake in the company to 2 per cent or below from 26 per cent within a period of one month.
