The weekly expiry contraction of November 2024 collapsed the Indian weekly options expiry calendar from five distinct weeklies across two exchanges down to two. The change was one of the six measures in the SEBI F&O entry barrier rules 2024 framework dated 1 October 2024 and became operative from 20 November 2024 with the cutover handled by NSE and BSE through staged delistings of the affected contracts.

Before November 2024, Indian retail option traders had access to five weekly expiries across the trading week: Tuesday for Nifty Financial Services, Wednesday for Nifty Midcap Select and BSE Bankex, Thursday for Bank Nifty and Nifty 50 , and Friday for Sensex . The five expiries collectively dominated retail F&O turnover, with weekly contracts contributing approximately 70 to 80 per cent of total index options volume on most trading days in 2023 and the first three quarters of 2024. The variety enabled retail traders to deploy strategies that operated daily on a different weekly contract, with the proximity to expiry generating the high theta-decay and gamma-risk profile that retail option sellers and short-dated buyers respectively were seeking.
