Como é calculada a taxa de câmbio?

Taxa de câmbio no Banco Central

Comerciantes e instituições compram e vendem moedas 24 horas por dia durante a semana. Para que ocorra uma troca, uma moeda deve ser trocada por outra. Para comprar Libras britânicas (GBP), outra moeda deve ser usada para comprá-la. Seja qual for a moeda utilizada, será criado um par de moedas. Se reais (BRL) forem usados ​​para comprar GBP, a taxa de câmbio é para o par GBP / BRL. As taxas em vigor para várias moedas principais estão disponíveis no site do Banco Central.

Taxa de câmbio hoje: como entender?

Se a taxa de câmbio USD / BRL for 1,5, isso significa que custa 1,5 reais para comprar 1 dólar americano. A primeira moeda indicada (USD) sempre representa uma unidade dessa moeda; a taxa de câmbio mostra o quanto da segunda moeda (BRL) é necessária para comprar essa unidade da primeira (USD).

Esta taxa diz-lhe quanto  custa comprar um dólar americano usando reais. Para descobrir quanto custa comprar reais usando dólares americanos use a seguinte fórmula: 1/taxa de câmbio.

Neste caso, 1 / 1,5 = 0.67. Custa US$0,67 para comprar um real. Este preço será refletido pelo par BRL / USD. Note que a posição das moedas mudou.

Vários sites oferecem taxas de mercado ao vivo para todos os pares de moedas. Se estiver procurando por uma moeda desconhecida, clique no botão “Adicionar moeda” e digite as duas moedas usadas para obter uma taxa de câmbio. Encontre gráficos, com taxas de mercado ao vivo, para a maioria dos pares de moedas também.
