Following the implementation the Private Securities Post-Trade Solution (Flow II), B3 identified the need to increase the number of decimal places in the “price” and “quantity” fields from 6 to 8, in the case of Closed-End Fund Shares (CFF) trades. We will therefore adjust the allocation process carried out in Real Time Clearing (RTC) to the flow of the previously existing product. Therefore, these trades can also be allocated through the new solution, which will now have full adherence to the products already integrated with it, namely, Debentures, Real Estate Receivables Certificates (CRI), Agribusiness Receivables Certificates (CRA) and Closed-End Fund Shares (CFF).

In the Securities Lending Subscription process, the "End Date", which refers to the last day for returning subscription rights from borrower to lender, will be removed from the RTC - Subscription Management Module screen. There will be no change to the Subscription Surplus event.  The BVBG.098 file will undergo changes where the respective field becomes optional.

The submission of orders for block trade solutions Midpoint Order Book (Midpoint) or Book of Block Trade (BBT) via the ePUMA trading station has undergone improvements. The goal is to enhance the user experience and streamline the routine. The update has brought greater ease for investors as the number of fields that need to be filled out when submitting an order will be reduced. Furthermore, the tool automatically locks fields that should not be filled out, thus minimizing the chance of errors. Here's how it works: #Automatic Filling: When the instrument symbol ending in "M" (Midpoing) is entered in the ticker field, the field "Type of market" will be automatically filled as Midpoint, thereby eliminating the need for the user to fill out two fields. # Error Prevention: When the user enters the instrument symbol ending in "M" (Midpoint) or "Q" (BBT), fields that do not need to be filled out will be locked, preventing potential input errors.

B3 Clearinghouse will soon begin to accept Real Estate Investment Funds (FIIs) shares as collateral for asset buy and sell trades. This measure aims to increase efficiency in capital allocation and expand the collateral options available to participants. Furthermore, investors will also be able to offset margins between assets with the same risk factor, which may reduce the total collateral requirement. The project contributes to the growth of the FII market and provides greater flexibility to investors.

Starting in July, B3's LINE Trading will adopt a new calculation for the TMOC and TMOV metrics, which define the maximum bid and ask sizes for options orders. The change will take effect in two stages: July 21, 2025, for Equity Options, and August 25, 2025, for Derivatives Options. Details of the update can be found in the LINE 5.0 | B3 version.

B3 is continually improving the operational flow of broker dealer accounts to offer greater efficiency and reliability to its clients. In 2024, it delivered some significant improvements, and will continue to advance with new implementations throughout 2025. These developments include greater automation of processes, increased operational capacity and solutions to optimize problem-solving in group dismantling, ensuring an increasingly seamless and secure experience.
