Where the data comes from
If your currency belongs to a country we cover, we use that country's official source when there is one: BCU in Uruguay (dollar, real and euro), BCP (dollar) and DNIT (real, Argentine peso and euro) in Paraguay, SBS/BCRP in Peru (dollar), the Central Bank of Chile's observed dollar, the TRM in Colombia, Banxico in Mexico (FIX dollar and euro), the BCV in Venezuela (dollar and euro), the BCB in Bolivia (dollar) and the BCC floating rate in Cuba (dollar and euro). The source used is shown below the result. The bolívar and the Cuban peso against the Argentine peso or other currencies come from crossing the BCRA dollar with the BCV official rate or the BCC floating rate of the same day. For all other pairs we use the official daily rates from the Central Bank (BCRA) in accordance with Communication A 3500, published in API of foreign exchange statistics, from 04/01/2016. Each currency is expressed in Argentine pesos; for a pair between two foreign currencies we split both contributions of the same day (exchange rate). It is a wholesale reference price: banks, exchange houses and cards charge their own price, with commissions and taxes. Unquoted days (weekends and holidays) repeat the last data.
