Exchange rates – daily bulletins

Concept:

Daily bulletin time series available since 2/1/2002, for the Euro, and since 28/11/1984, for the other currencies. For the American Dollar, this data set shows administered rates until 13/3/1990 and free rates from then on (Resolution 1690/1990). Administered rates are those set by the Central Bank of Brazil; from March, 1992, this rate started being called Ptax rate (close). Between 13/3/1990 and 30/6/2011, this rate was calculated as the average rate, weighed by volume, of all interbank operations traded on that day. Starting on 1/7/2011 (Circular 3506/2010), the Ptax rate calculation corresponds to the arithmetic average of four daily quotes provided by Central Bank of Brazil’s foreign exchange dealers; the quotes must reflect market conditions at that time. Parities of the other currencies against the American Dollar (USD) are obtained from information agencies. Currencies rates against the Brazilian currency are calculated dividing the Brazilian currency rate against the American Dollar by the parities against the American Dollar for type A currencies, and multiplying the Brazilian currency rate against the American Dollar by the parities against the American Dollar for type B currencies.

Available currencies:

  • Danish Krone (DKK) Type A
  • Norwegian Krone (NOK) Type A
  • Swedish Krona (SEK) Type A
  • American Dollar (USD) Type A
  • Australian Dollar (AUD) Type B
  • Canadian Dollar (CAD) Type A
  • Euro (EUR) Type B
  • Swiss Franc (CHF) Type A
  • Japanese Yen (JPY) Type A
  • British Pound (GBP) Type B

Unit of measure:

Type A currencies: Parity (American Dollar): quantity in the currency per one unit of American Dollar (USD);
Rates (Brazilian currency): quantity in the Brazilian currency per one unit of the currency

Type B currencies: Parity (American Dollar): quantity in American Dollars (USD) per one unit of the currency;
Rates (Brazilian currency): quantity in the Brazilian currency per one unit of the currency

Example of how to calculate type A currencies rates in the Brazilian currency, considering the Real (BRL) as the domestic currency and the Canadian Dollar (CAD) as the foreign currency:

CADBRL bid rate = USDBRL bid rate ÷ USDCAD offer parity
CADBRL offer rate = USDBRL offer rate ÷ USDCAD bid parity

Example of how to calculate type B currencies rates in the Brazilian currency, considering the Real (BRL) as the domestic currency and the Euro (EUR) as the foreign currency:

EURBRL bid rate = EURUSD bid parity × USDBRL bid rate
EURBRL offer rate = EURUSD offer parity × USDBRL offer rate
