The detailed risk management framework has been finalised after a due consultative process with the exchanges.
The circular will be implemented by January 1, 2016, the Securities and Exchange Board of India (Sebi) said.
All recognised associations under the Forward Contracts (Regulation) Act, 1952 are deemed to be stock exchanges under the Securities Contracts (Regulation) Act, 1956, with effect from September 28, 2015, the day when merger of commodity markets regulator FMC with Sebi became effective.
Mark to market settlement on all open positions of clients/members will be done on a daily basis in cash.

The regulator has asked the exchanges to maintain Settlement Guarantee Fund (SGF) which will be used by them only for the purpose of providing settlement guarantee.
Initial and additional margins or any other margins as may be specified by Sebi from time to time will be deducted from the liquid assets of a clearing member.
According to Sebi, the exchanges will lay down exposure limits either in rupee terms or as percentage of the total 'Liquid Assets' that can be exposed to a single bank directly or indirectly.
The total exposure towards any bank would include bank guarantees issued by the bank as well as debt or equity securities of the bank which have been deposited by members towards total liquid asset.
Cash equivalents will be at least 50 per cent of liquid assets.
Exchanges will have to adequately diversify their collateral so as to avoid any concentration of exposure towards any single entity and the same shall be within limits as may be prescribed by Sebi from time to time.
