What Is a Currency Pair?
In the foreign exchange (forex) market, currencies are always traded in pairs. A currency pair represents the exchange rate between two currencies — showing how much of the quote currency is needed to buy one unit of the base currency.
For example, in the pair EUR/USD, the Euro is the base currency and the US Dollar is the quote currency. If EUR/USD is trading at 1.0850, it means one Euro buys 1.0850 US Dollars.
The Three Categories of Currency Pairs
Major Pairs
Major pairs all include the US Dollar on one side. They are the most heavily traded pairs in the world, offering the highest liquidity and typically 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
Major pairs are generally recommended for beginners due to their stability and abundance of available analysis and news coverage.
Minor Pairs (Cross Pairs)
Minor pairs, also called cross pairs, do not include the US Dollar but involve other major currencies. Examples include:
- EUR/GBP — Euro / British Pound
- EUR/JPY — Euro / Japanese Yen
- GBP/JPY — British Pound / Japanese Yen
- AUD/CAD — Australian Dollar / Canadian Dollar
Minor pairs have somewhat wider spreads than majors and can exhibit distinct behavior tied to regional economic factors — like commodity prices affecting AUD or CAD pairs.
Exotic Pairs
Exotic pairs combine a major currency with the currency of an emerging or smaller economy. Examples include:
- USD/TRY — US Dollar / Turkish Lira
- EUR/ZAR — Euro / South African Rand
- USD/MXN — US Dollar / Mexican Peso
- USD/SGD — US Dollar / Singapore Dollar
Exotic pairs carry higher risk due to lower liquidity, wider spreads, and sensitivity to political or economic instability in the smaller country. They are generally not recommended for new traders.
Key Concepts for Reading Currency Pairs
The Spread
The spread is the difference between the buy (ask) price and the sell (bid) price. It represents the broker's cost and is measured in pips. Tighter spreads are preferable — they reduce your trading costs. Major pairs typically have the tightest spreads.
Pips and Pipettes
A pip (percentage in point) is the smallest standard price movement in a currency pair. For most pairs, one pip equals 0.0001 of the quoted price. A pipette is one-tenth of a pip (0.00001), used by brokers offering fractional pricing.
Lot Sizes
Forex is traded in lots. A standard lot equals 100,000 units of the base currency. Mini lots (10,000 units) and micro lots (1,000 units) allow traders with smaller accounts to participate with controlled risk.
How to Choose Which Pairs to Trade
- Start with major pairs — EUR/USD and GBP/USD are ideal for beginners due to liquidity and information availability
- Consider your trading hours — Some pairs are most active during specific market sessions (e.g., GBP/USD is most active during the London session)
- Assess your risk tolerance — Exotic pairs carry greater volatility and risk; stick to majors and well-known crosses until you build experience
- Follow your analysis — Trade the pairs you understand best and can analyze most confidently
Final Thoughts
Understanding currency pairs is the foundation of forex trading. Before placing any trade, make sure you understand what you're buying, what you're selling, and why the pair is likely to move in your anticipated direction. Start with the majors, build your skills, and expand your watchlist gradually as your experience grows.
