The Banco Central do Brasil (BCB) formally gained autonomy via Complementary Law 179 in 2021. The COPOM committee meets 8 times per year over 2-day sessions, setting the SELIC target by vote of the Governor and 8 Deputy Governors. Minutes released within 4 business days.

Operational Toolkit

  • Reserve requirements on demand, time, and savings deposits
  • Daily repo operations (compromissadas) to absorb excess liquidity
  • FX swaps (settled in local currency) to stabilize BRL without depleting hard reserves

Political Friction

Staggered mandates create structural tension: new presidents work with incumbent BCB governor for their first 2 years. Lula vs. Campos Neto conflict centered on whether double-digit SELIC unnecessarily stifles growth and inflates debt servicing costs. See Sovereign Debt and Capital Flows.
