Overview

• The minimum block deal size would rise to Rs 25 crore from Rs 10 crore to move sub‑scale trades onto the on‑screen order book.
• Block trades would be confined to two windows, with morning executions at the previous close and afternoon executions at a VWAP calculated from 1:30–2:00 pm.
• Price limits would be set at 1% for F&O stocks and 3% for non‑F&O shares under the defined reference prices.
• Every block trade must result in delivery with no squaring off, and the regime would mirror regular‑market settlement and risk controls with same‑day after‑hours disclosure of buyer and seller details.
• SEBI is inviting feedback until Sept. 15, with final norms to start 30 days after a circular is issued, as early industry reactions signal support for deeper liquidity.
