Brazil’s National Complementary Pension Council has opened a public consultation on a draft resolution prepared by the Brazilian Pension Funds Authority (PREVIC) to amend CNPC Resolutions No. 40/2021 and No. 50/2022 for closed supplementary pension entities. The proposal aims to increase predictability and legal certainty around the criteria and indices used to update participants’ and beneficiaries’ benefits and to refine the rules governing key member options. For CNPC Resolution No. 40/2021, the proposed changes focus on strengthening requirements for the content of benefit plan regulations, particularly the criteria and indices used for benefit adjustments, including proposed limits intended to avoid instability in beneficiaries’ income. For CNPC Resolution No. 50/2022, the draft seeks to strengthen legal certainty and protection of participants’ funded resources, preserve the pension character of accumulated reserves, and align the rules for the deferred proportional benefit, portability, redemption and self-sponsorship with sector developments following the creation of the Plano Instituído de Preservação da Proteção Previdenciária (PIPPP) under CNPC Resolution No. 59/2023. Comments must be submitted via the Participa + Brasil platform by 23:59 on 14 September 2025.
