India's Bombay Stock Exchange (BSE) has announced that it will retain weekly expiry options linked to the Sensex index despite new rules for derivatives introduced by the Securities and Exchange Board of India (SEBI). However, the BSE will discontinue weekly index derivatives contracts on the Sensex 50 and BANKEX indices. The discontinuation of Sensex 50 contracts will take effect from November 14, 2024, while the BANKEX contracts will be discontinued from November 18, 2024. These changes come as part of SEBI's broader regulatory adjustments in the derivatives market.
