Can I trust the Selic Daily effective values?
Yes. The module pipes data strictly authenticated by the Brazilian Central Bank. The effective Selic updates are legally suitable for debt recalculations and financial modeling.
Does it include expected adjustments set by COPOM?
Absolutely. By integrating the Focus expectations array, your AI is acutely aware of forward market opinions preceding actual COPOM rate cut decisions.
