Regulatory norms on F&O should evolve based on continuous market feedback: Sundararaman Ramamurthy
«Also, risks do not materialise only in weekend. It happens every day. If there is a product to attract global risks on Monday, then if there is something materialising in between, it is a meaningful gap there should be another product,» says Sundararaman Ramamurthy, MD & CEO, BSE.
What are the potential risks to the market ecosystem when there is a concentration of trading activity on a single expiry day?
Sundararaman Ramamurthy: The regulator gave the option for selecting one expiry day by the exchanges. The regulators absolutely, of course, would have applied their mind for giving this option. NSE opted to continue for Thursday. Based on market feedback, we shifted it to Tuesday. Market feedback had a rationale for it. When you have a common expiry, an existing mature product trades more and no other product can enter in.
So, in the process, it will be a significant concentration risk and an evolution of monopoly. Avoidance of concentration risk and having meaningful competition are hallmarks of a free market. So, the unified expiry day did not get much of a traction from market participants.
Also, risks do not materialise only in weekend. It happens every day. If there is a product to attract global risks on Monday, then if there is something materialising in between, it is a meaningful gap there should be another product. Otherwise, the products will be rolled over for buying extra protection only to the next week of the same product, not to any other product. In the process, concentration increases. What
