| Summary Methodology |
| Analytical framework, concepts, definitions, and classifications (including reference to applicable guidelines) |
| The
exchange rate for the U.S. dollar, known on the market as the PTAX rate, is the average of
the effective rates of transactions on the interbank market, with settlement two business
days after the transaction date, weighted by transaction volumes. Transactions closing at
rates that diverge most from the average on the market (outliers) are eliminated from the
calculation. The eliminated portion does not exceed 5 percent of the volume traded and is
determined based on a symmetry test, using the Pearson asymmetry coefficient, establishing
the upper and lower rates for elimination. If one or more transactions show evidence of
artificial price formation or are contrary to regular and sound market practices, they
will also be eliminated. The par values of other currencies and units of account in relation to the real are determined based on the price of these currencies in U.S. dollars published by Reuters and Bloomberg at the closing of the domestic market, and the PTAX rate for the U.S. dollar, determined as indicated in the preceding paragraph. |
| Scope of the data (coverage of, e.g., institutional units, transactions and stock, commodities, industries, and geographic areas) |
| In
addition to the U.S. dollar exchange rate, par values for the about 141
other currencies and units of account of international organizations, specifically
the currencies of the G-7 countries, the European Union, and MERCOSUR; special
drawing rights; and the unit of value of the Bank and of the African Development
Fund.
Operations included in the calculation of the PTAX rate are carried out by financial institutions authorized to deal in foreign exchange by the Central Bank of Brazil, which represent practically all banking institutions in operation in the country and, therefore, reflect prevalent conditions throughout the country. |
| Accounting conventions (e.g. time of recording, valuation methods) |
| The PTAX rate is calculated daily, after the closing of the domestic foreign exchange market (7:00PM, Brazilian time). |
| Nature of the basic data (e.g., administrative records, surveys censuses, combinations of these) |
| The database is made up of the foreign exchange contracts of all interbank foreign exchange transactions. Pursuant to the rules governing the domestic exchange market, the foreign exchange contracts of all transactions are recorded in the electronic system (SISBACEN), which links the Central Bank of Brazil to all financial institutions in operation in the country. These virtual contracts include, among other information, the participating institutions, the agreed exchange rate, the volume of foreign currency, and the date of settlement of the transaction. |
| Compilation practices (e.g., weighting schemes, imputation methods, balancing/cross-checking techniques) |
| The PTAX rate is the average of the effective rate of each interbank transaction on the exchange market, weighted by the volume of transactions and excluding transactions whose rates exceed the limits established in a symmetry test for the series of transactions. |
| Other aspects (e.g., seasonal adjustment, disclosure avoidance, base years, reference years, transformations from fiscal to calendar years) |
| In the calculation of the PTAX rate there are no adjustments or conversions, except for those described above. |
