What is the difference between Selic and CDI?

Selic is the overnight rate for government bond-backed interbank loans, set/targeted by the COPOM. CDI is the interbank rate for unsecured overnight deposits between banks. CDI closely tracks Selic and is the most common benchmark for fixed-income investments in Brazil.

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.
