CMN Resolution No. 4,958 — Minimum Requirements for Reference Equity, Tier 1 and Core Capital and Additional Core Capital

The resolution establishes minimum capital requirements for financial institutions, mandating minimum levels for Reference Equity (8% of risk-weighted assets), Tier 1 capital (6%), and Core Capital (4.5%). It introduces an Additional Core Capital (ACC) surcharge composed of conservation (2.5% from April 2022), countercyclical (up to 2.5%), and systemic (up to 2%) components, with specific application rules for different institution segments. Non-compliance with ACC triggers restrictions on variable remuneration, dividends, share repurchases, and capital reductions, scaled based on the degree of insufficiency. The regulation also defines the calculation methodology for risk-weighted assets and mandates the deduction of excess fixed asset investments from capital bases.
