In forex quoting, what does the first currency in a currency pair represent?
Answer
Base currency
In forex quoting, the first currency in a currency pair represents the base currency.
The base currency is the reference unit: the quoted exchange rate tells you how many units of the second currency are needed to buy one unit of the first. In EUR/USD 1.2500, for example, EUR is the base currency and USD is the quote currency, meaning €1 equals $1.25.
The second currency is also called the counter currency or quote currency. Traders sometimes confuse “base currency” with a bank’s accounting or functional currency, but in a currency-pair quote the term specifically describes the currency listed first.
The order is conventional rather than interchangeable. Reversing EUR/USD to USD/EUR changes the numerical rate to its reciprocal and changes which currency is being valued. Commonly traded pairs such as EUR/USD, GBP/USD and USD/JPY follow this first-versus-second structure.
