What Is a Currency Pair?
In the foreign exchange (forex) market, currencies are always traded in pairs. When you buy one currency, you are simultaneously selling another. The pair is expressed as a ratio — for example, EUR/USD 1.08 means one euro buys 1.08 US dollars.
The first currency is the base currency, and the second is the quote currency. Understanding how pairs are structured is the foundation of forex trading.
The Three Categories of Currency Pairs
Major Pairs
Major pairs all involve the US dollar (USD) on one side. They are the most traded and most liquid pairs in the world, featuring the tightest spreads.
- EUR/USD — Euro / US Dollar
- GBP/USD — British Pound / US Dollar
- USD/JPY — US Dollar / Japanese Yen
- USD/CHF — US Dollar / Swiss Franc
- AUD/USD — Australian Dollar / US Dollar
- USD/CAD — US Dollar / Canadian Dollar
- NZD/USD — New Zealand Dollar / US Dollar
Minor Pairs (Cross Pairs)
Minor pairs do not include the US dollar. They often have slightly wider spreads but still offer good liquidity.
- EUR/GBP — Euro / British Pound
- EUR/JPY — Euro / Japanese Yen
- GBP/JPY — British Pound / Japanese Yen
- AUD/JPY — Australian Dollar / Japanese Yen
Exotic Pairs
Exotic pairs combine a major currency with a currency from an emerging or smaller economy. They tend to have higher spreads, lower liquidity, and greater volatility.
- USD/TRY (Turkish Lira)
- EUR/ZAR (South African Rand)
- USD/BRL (Brazilian Real)
- USD/MXN (Mexican Peso)
What Moves Currency Pairs?
Currency values are influenced by a range of macroeconomic and geopolitical factors:
- Interest rate decisions — Central banks raising rates typically strengthen a currency
- Inflation data — High inflation can erode currency value
- Employment figures — Strong jobs data often signals economic health
- GDP growth — Expanding economies attract foreign capital
- Political stability — Uncertainty weakens currency demand
- Trade balances — Export-heavy nations see stronger demand for their currency
Choosing the Right Pair to Trade
As a beginner, it's best to start with major pairs. EUR/USD is widely recommended because it offers deep liquidity, tight spreads, and an abundance of analytical resources. As you grow more experienced, you can explore minors and selectively trade exotics when specific opportunities arise.
Understanding Pips
A pip (percentage in point) is the smallest standard price movement in a forex pair. For most pairs, this is the fourth decimal place (0.0001). For JPY pairs, it's the second decimal place (0.01). Knowing your pip value is essential for calculating profit, loss, and appropriate position sizes.
Key Takeaway
Start with majors, understand what drives each economy, and always factor in liquidity and spread costs before entering any trade. Currency pairs are the building blocks of forex — and understanding them deeply gives you a real edge.
