The decision to this effect has been taken by various stock exchanges in consultations with the capital markets regulator, Securities and Exchange Board of India (Sebi).
As a payment crisis involving an amount of over Rs 5,600 crore emerged at the exchange in late July, NSEL had to suspend trading following a government directive.
The exchanges have disabled Unique Client Codes (UCC) of three entities --Aastha Minmet India, MSR Food Processing and Metkore Alloys & Industries. All entities need UCC to trade on a stock exchange platform.
"In consultation with Sebi and other exchanges, as a proactive measure, to protect market integrity and to safeguard market participants' interest and as a risk management measure, it has been decided to disable UCC of above three entities from trading with immediate effect," NSE and BSE said in a similar worded circular dated October 30.
"Members are further advised not to register any of the three defaulted entities mentioned above as their clients till further notice," they added.
In a separate circular, BSE today said that it has fixed 20 per cent circuit limit for Jignesh Shah-led Financial Technologies (India) Ltd. This would be effective from Friday.
