How the BCB PTAX rate is used
- Settlements and reporting
Official rates are the reference for accounting, financial reporting and regulated settlements.
- Analysis and planning
A consistent base for financial analysis, budgeting and assessing currency risk.
- Comparison with the market
An official rate can differ from a market rate: mind the purpose of the calculation and the source it requires.
About this rate
Banco Central do Brasil publishes official reference rates on its working days. This page shows the rate for the date it applies to and its history over the past year. A reference rate is not a price you can trade at: banks and exchange offices quote their own buy and sell rates around it.
On days without a publication the last published rate remains the latest.
