The Securities and Exchange Board of India (SEBI) is expected to soon issue a final circular regarding the expiry day framework for derivatives trading on Indian stock exchanges. Sources indicate that SEBI may grant Tuesday as the official expiry day to the National Stock Exchange (NSE), a move aimed at aligning weekly derivative expiry days across exchanges to streamline trading and reduce market volatility. The NSE has reportedly applied for Tuesday as its expiry day, while the Bombay Stock Exchange (BSE) has not submitted any proposals to SEBI concerning the weekly expiry date and will comply with SEBI regulations. NSE officials, including CEO Ashish Chauhan, have revealed that they previously sought to shift their expiry day to Monday and have requested SEBI's approval for the NSE initial public offering (IPO). SEBI Chairman Tuhin Kanta Pandey has stated that all outstanding issues related to the NSE IPO will be resolved soon, although no specific timeline has been provided. Both SEBI and NSE are actively collaborating to move forward with the IPO process. Additionally, market reactions have been noted, with BSE shares dropping 5% amid reports of the potential expiry day change. The regulatory developments are part of broader efforts by SEBI to enhance market stability and oversight.
