This new rule will come into effect on December 7, 2025. SEBI issued this information in a circular on Wednesday. If you buy or sell in the stock market, it is very important for you to know this new rule.
Rules related to block deal
According to a CNBC report, SEBI has also stated that the floor price for a block deal can now be up to 3 percent above or below the previous day’s closing price. Previously, this limit was only 1 percent. This means that block deals will now offer a little more leeway in pricing. Two time windows have been set for block deals. The first window will be from 8:45 am to 9:00 am. During this time, the floor price will be the previous day’s closing price. The second window will be from 2:05 pm to 2:20 pm. During this time, the floor price will be based on the volume-weighted average price (VWAP) of trading in the cash segment between 1:45 pm and 2:00 pm. Stock exchanges will share VWAP information between 2:00 pm and 2:05 pm.

Stock exchanges will be required to make public all block deal details, such as the name of the stock, the name of the client, the number of shares bought or sold, and the trade price, after market hours on the same day.
SEBI issued circular
These rules will also apply to the optional T+0 settlement cycle. SEBI has directed stock exchanges, clearing corporations, and depositories to implement trading, settlement, surveillance, and risk control measures similar to those in normal trading. Necessary systems must be put in place for this purpose. SEBI also mandated that this circular be made available to all investors and market participants and posted on stock exchange websites. These rules will come into effect 60 days from the date of issuance of the circular, i.e., December 7, 2025.
