In the event of a client default, the broker always has to make up the shortfall from its own funds in the current practice. However, the industry association ANMI (Association of National Exchanges Members, India) points out, quite correctly that there has never been any serious default in the 25-odd years of the electronic trading system.
In the new system, according to brokers, margin-traders will have to put down roughly 20 per cent of the trade value before they execute a trade and the broker could be punished if there is a shortfall or false reporting in terms of margins. Even if the broker is prepared to bear the margin risk, the regulator will not allow it. If traders cannot find the cash (or pledge securities) upfront, this could lead to significant reduction of volumes in the cash market where over Rs 30,000 crore of trades occur on an average day across national exchanges. After December 2020, the margin requirements will be even stiffer as the Securities and Exchange Board of India (Sebi) wants a move to a six-sigma margin Value-at-risk (VAR) system from the current 3.5 sigma. Margins will, therefore, increase again after December.
