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.

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.

B3 has implemented an improvement to the margin call process in asset lending transactions. Now, when the borrower returns an asset to the lender, there will no longer be a margin call between the 11:00 AM and 4:00 PM windows. This is because the asset is being returned to the portfolio of the lender who is the asset's owner. This eliminates the need to use liquidity resources during this time interval.

Starting October 1, 2025, B3 will publish securities lending renewal rates directly on its website through the Daily Market Bulletin (BDM). The data will be available in the Clearinghouse chapter on the "Asset Lending - Renewals" table.
