Markets Regulator SEBI has proposed to increase the minimum order size for the execution of trades in the block deal window, which is currently ₹ 10 crore to ₹ 25 crore.
The current threshold came into force from 2017.
A block deal is a large business of share shares that occur between a buyer and a seller through the same transaction in the stock exchange. It can only be executed by stock exchanges during a special 15-minute window provided twice a day.
In its consultation paper, SEBI proposed that “the minimum order size for the execution of trades in the block deal window will be 25 crores. Each trading executed in the block deal window should result in delivery and will not be closed or reversed.” With the high border, SEBI has proposed to review the pricing mechanism for such trades. It is considering increasing the price band for non-renovated stock by 3 percent, while maintaining the existing 1% band for futures and options (F&O) scrips.
The move is expected to reduce the risk of manipulation in the market.
Currently, trades can only be executed within 1% band on either side of the closing value of the previous day.
The consultation paper further details the operation hours of the block deal window. The morning session will run between 8:45 am to 9 am, with trades executed at the closing price of the previous day. The afternoon session, from 2:05 pm to 2:20 pm, will use the amount of trades executed in the cash segment between 1:30 pm and 2 pm.
These windows are designed to provide buyers and sellers to provide a platform to execute large share transactions that are usually already interacted.
To increase transparency, SEBI said that the stock exchanges spread the details such as the name of the scrip, the name of the customer, the amount of shares, and the price of the business for the public on the same day after the market hours.
The Securities and Exchange Board of India (SEBI) has demanded public comments on the proposals till 15 September.
