Itaú Unibanco
Largest private bank in Brazil and Latin America, running a R$1.5 trillion loan book.
Itaú keeps growing profit and share in corporate and wealth banking while digital rivals like Nubank chip away only at the mass-market edge.
Itaú Unibanco is a giant Brazilian bank that serves 60 to 70 million customers and makes money from corporate foreign exchange deals, wholesale banking, wealth management, and insurance. Rivals like Nubank and Mercado Pago are taking some mass-market customers with simpler, cheaper services, but they have not yet cracked into the lucrative business of serving big companies or managing wealth for rich clients, which is where Itaú makes most of its money; AI is not a threat because banking requires a government license that only Itaú has. The biggest risk is if Nubank figures out how to compete for small and mid-sized business customers, or if Brazil's government rules against Itaú's digital wallet business.
CADE's antitrust ruling on digital-wallet restrictions moves past appeal to a final remedy. Would show regulators forcing open Itaú's payment rails rather than leaving its moat intact.
Itaú reports ROE below 18% for two straight quarters without a macro shock explaining it. Would show real profitability erosion rather than just headline growth continuing.

- Federal police probe alleges effort to compile dossier on Itaú CEO, July 2026.
- Brazil's 2026 election year macro conditions (Selic, credit quality) could pressure margins.
- Nubank's brand-sentiment lead and mass-market share gains erode retail positioning.

- Is Itaú Unibanco profitable in 2026?
- Yes. Itaú Unibanco reported Q1 2026 recurring managerial net income of R$12.3 billion, up 10% year over year, with consolidated ROE of 24.8% and a record 34.9% efficiency ratio in Brazil, per its May 5, 2026 earnings release.
- Who owns Itaú Unibanco?
- Itaú Unibanco is controlled by IUPAR, jointly held by Itaúsa (Egydio de Souza Aranha family) and Companhia E. Johnston de Participações (Moreira Salles family); Itaúsa also directly holds a large common-share stake, per a 2021 SEC filing describing the historical ownership structure.
- Can Nubank replace Itaú Unibanco?
- Not yet. Nubank was ranked Brazil's strongest banking brand by customer sentiment in March 2026 and leads in mass-market retail, but Itaú still holds 19.7% share of commercial FX and remains untouched in wholesale banking and wealth management as of 2026.
- Is Itaú Unibanco cutting jobs?
- Headcount fell to 92,470 employees as of December 31, 2025, down 3.9% from 96,219 a year earlier, according to stockanalysis.com; the bank also closed 319 branches in 2025, ending the year with 1,953 branches.
- Is Nubank Itaú Unibanco's biggest competitor?
- Nubank is the top digital challenger and was ranked Brazil's strongest banking brand by sentiment in March 2026, but Itaú remains Brazil's most valuable banking brand at roughly US$9.9 billion, up 15% year over year, and the largest bank by assets in Latin America.
- Will AI replace jobs at Itaú Unibanco?
- Itaú runs over 1,300 AI models in production as of mid-2025 and closed 319 branches in 2025, showing AI-linked efficiency gains, but its banking license and credit-underwriting liability, covering a R$1.5 trillion loan book as of March 2026, cannot be automated away.
