The regulations were aimed at reducing the weekly expiries of other indices, so the National Stock Exchange ceased weekly options for indices such as Bank Nifty, Nifty Financial Services (Fin Nifty), and Nifty Mid-Cap, retaining only Nifty 50 weekly options. Thus, effective from November 20, 2024, Fin Nifty will stop weekly expiries but will maintain monthly expires.
