Nubank has received approval from the Central Bank of Brazil to complete its acquisition of Banco Porto Real de Investimentos S/A, allowing the digital banking group to obtain a Brazilian banking license and retain its Nubank name under new regulations. The transaction addresses compliance requirements introduced by Joint Resolution No. 17, issued on November 28, 2025, by the Central Bank and the National Monetary Council. The resolution requires financial institutions to use names that accurately describe their authorized businesses and services. Nubank will add banking activities to its existing payment institution, credit, financing, investment and securities brokerage operations. Brazil remains Nubank's largest market, with 120 million customers in the country and 140 million across all markets. The company has invested 45 billion reais ($7.9 billion) in Brazil, reaches one in five adults and serves 65% of the adult population. Activity in the country rose for a seventh consecutive quarter to a record 86.3% during the third quarter. Nubank has also expanded into the U.S. through a bank partner model with Kansas City-based Lead Bank after conditional approval from the Office of the Comptroller of the Currency in January. Its Nu Global product is a USDC account that supports cross-border transfers and crypto payments through an associated credit card. Executives said the Brazilian license reinforces trust in Nubank and the national financial system, while even a small share of the U.S. market could transform the business.
