Sebi to consider same-day expiry across exchanges: report

Market regulator Securities and Exchange Board of India (Sebi) plans to float a consultation paper on ending weekly futures and options (F&O) contracts within a month, according to a CNBC TV18 report. Further, the regulator is planning a transition to monthly expiries with a defined glide path, may consider same-day expiry across exchanges, the report added. 

 

The consultation paper is also likely to propose curbs on retail participation in the derivatives markets, suggesting a threshold for the same, the report said. 

 

Last month, Tuhin Pandey, Sebi Chairman, said that the regulator is looking for ways to increase the tenure and maturity of equity derivatives contracts. "The aim is to deepen the cash equity market, which forms the true foundation of capital formation," said Pandey. While daily trading volumes in the cash market have doubled over the past three years, much more needs to be done, he added.

 

We will consult stakeholders on ways to improve and carefully calibrate the tenor and maturity profile of derivative products so that they support both hedging and long-term investing," he added. 

Options on a new clock

Equity market traders saw a marked shift in trading patterns as the National Stock Exchange (NSE) and BSE swapped the expiry days for their derivatives contracts. 

 

From September, NSE’s weekly Nifty contracts started expiring on Tuesdays instead of Thursdays, while BSE’s Sensex contracts moved to Thursdays instead of Tuesdays. Analysts expect this swap could shift market share in index options trading, with NSE likely to reclaim some lost ground from BSE.
