Nov 28 (Reuters) - Brazil's central bank established on Tuesday new procedures for calculating the capital requirement for operating risks for banks, which will imply an increase of 34 billion reais ($6.98 billion) in the total capital requirements of the country's financial system.

The procedures will come into force on the first day of 2025, but will be implemented in phases until 2028, softening the impact on capital requirements, the central bank said.

The changes in procedures represents Brazil's adoption to the recommendations of the Basel Committee on Banking Supervision, under the Basel III set of measures. ($1 = 4.8705 reais) (Reporting by Fabricio de Castro; Writing by Peter Frontini; Editing by Chris Reese)
