Quick Definition

A quotation of two different currencies where one is expressed in terms of the other, forming the basis of all forex trading.

What Is Currency Pair?

A currency pair is the quotation of two currencies traded against each other in the forex market. Every forex transaction involves simultaneously buying one currency and selling another. The pair is written as two currency codes separated by a slash, such as EUR/USD, GBP/JPY, or USD/CHF.

The first currency in the pair is called the base currency, and the second is the quote currency (or counter currency). The exchange rate tells you how much of the quote currency is needed to purchase one unit of the base currency. For example, if EUR/USD = 1.0900, it takes 1.09 U.S. dollars to buy one euro. When you "buy" a currency pair, you are buying the base currency and selling the quote currency; when you "sell," you do the opposite.

Currency pairs are categorized into three main groups:

  • Major pairs: Include the U.S. dollar and are the most heavily traded (EUR/USD, USD/JPY, GBP/USD, USD/CHF, AUD/USD, USD/CAD, NZD/USD)
  • Cross pairs (minors): Do not include the U.S. dollar but involve other major currencies (EUR/GBP, EUR/JPY, GBP/JPY)
  • Exotic pairs: Pair a major currency with the currency of a developing or smaller economy (USD/TRY, EUR/ZAR, USD/THB)

Each category has different characteristics in terms of liquidity, spread, and volatility. Major pairs typically have the tightest spreads and deepest liquidity, while exotic pairs tend to have wider spreads and can experience more dramatic price swings. Understanding how currency pairs work is the foundational skill for any forex trader.
