Where the rate comes from
The values are the Central Bank's daily series for the commercial dollar (selling rate). The rate you see at an exchange house or on your card is different, because it includes a spread and the IOF financial transactions tax.
Why the dollar goes up and down
The exchange rate reacts to interest rates in Brazil and the United States, commodity prices, public finances and investor sentiment. No single factor explains the moves on its own.
