São Paulo – Itaú Unibanco, the largest bank in Brazil and Latin America, saw its Common Equity Tier 1 (CET1) capital ratio decline to 12.3% in the fourth quarter of 2025, the lowest level in two-and-a-half years, according to a report by Risk.net. The 1.2 percentage point decrease represents the largest quarterly drop since the first quarter of 2020.
