Banco do Brasil Taps Márcio Chiumento to Lead Previ After Fukunaga Resigns

Overview

• João Luiz Fukunaga resigned on October 17 and will take the Government Relations and ESG director role at EloPar.
• Banco do Brasil indicated Participações director Márcio Chiumento to assume the Previ presidency, with the mandate running through May 31, 2026.
• Adriana Chagastelles will head Participações, becoming the first woman indicated by the sponsor for a director position at the entity.
• The TCU ordered a full audit in April 2025 after Plano 1 posted a roughly R$17.4–R$17.6 billion deficit for 2024, which Previ says shifted to a R$1.48 billion surplus by August.
• The shake-up at Previ caps a broader leadership refresh across BB-affiliated companies led by CEO Tarciana Medeiros since July, according to Valor Econômico.
