The firm is also weighing internal candidates including Luiz Masagao, vice president of products and clients, the people said, asking not to be identified discussing personnel decisions.
B3 is looking to replace Gilson Finkelsztain, who was named CEO of Banco Santander Brasil last month, the people said.
Bettamio, a veteran dealmaker, was BofA’s global co-head of investment banking until August, when he was named co-chairman of global corporate and investment banking.
He became head of Merrill Lynch’s Brazilian investment banking unit in March 2008 and took over as CEO of the entire business in September of that year. The company promoted him to head of Latin America in 2013.
Masagao, vice president of products and clients at B3, joined the firm in 2024 from Banco Santander, where his roles included head of markets for Latin America, according to his LinkedIn profile. He previously worked at Morgan Stanley and Citi. —Rachel Gamarski and Cristiane Lucchesi, Bloomberg News
