Circular No. 3979 — Establishes and updates the operational risk database and requires remittance to the Central Bank of Brazil of information on operational risk events

This Circular requires financial institutions in Segment 1 (S1) and Segment 2 (S2) to establish and maintain an operational risk database containing specific data fields for all operational risk events, including cyber and socio-environmental risks. Institutions must report this data to the Central Bank of Brazil semi-annually, covering a ten-year lookback period with a phased transition schedule ending in 2025. Individual reporting is mandatory for losses exceeding R$1,000 or uncovered legal risks exceeding R$10 million, while smaller events are aggregated. The regulation takes effect on December 1, 2020, with a delayed effective date of June 1, 2021, for S2 institutions.
