SEBI is considering significant changes to the derivatives segment, including extending the tenure of Futures & Options (F&O) contracts. The regulator may phase out weekly expiries in favor of monthly ones, aiming to simplify the structure and reduce the number of expiry days. According to sources, SEBI is in talks with stock exchanges, which have also proposed shifting to monthly expiries. A final consultation paper outlining these changes is expected soon. SEBI Chairman has indicated a clear direction toward reducing market volatility and speculation linked with frequent contract expiries.
