Itaú Unibanco is Brazil's largest privately-owned bank by assets, serving roughly 70 million clients across retail and wholesale banking, insurance, asset management, and investment banking. The retail segment — the largest by revenue — serves individuals and SMEs across three income tiers (Retail, Uniclass, and Personnalité), offering checking accounts, credit cards, personal loans, payroll loans, mortgages, vehicle financing, insurance, and investment products. Itaú holds a 24% share of credit card purchase volume in Brazil and is the largest private mortgage lender. The wholesale segment operates under Itaú BBA and serves mid-market and large corporate clients; Itaú BBA is the #1 M&A advisor and DCM originator in Brazil. Itaú also runs the largest privately-owned asset manager in Brazil with R$1,236B in AUM and holds 31.1% of the private banking market. Itaú earns revenue through net interest income (the largest driver), service fees and commissions, insurance premiums, and treasury gains. The bank operates through a network of 2,277 branches, supplemented by digital channels that now handle over 99% of transfers and payments. Outside Brazil, Itaú operates primarily in Chile, Uruguay, and Paraguay, though international operations account for only about 8% of earnings. Itaú has been investing in digital transformation, including a unified super-app rolled out to 50 million clients, to compete with digital-native challengers like Nubank.
