2. What Is a Currency Pair

A currency pair is the quotation of two different currencies in the foreign exchange market. It represents the value of one currency relative to another. Every forex transaction involves the simultaneous purchase of one currency and the sale of another, which is why currencies are always traded in pairs.

Currency pairs form the core of all forex trading and are used by individuals, businesses, governments, and central banks to facilitate international trade, investment, and speculation.
