Forex Currency Pairs Explained
In the forex market, currencies are always traded in pairs. When you buy one currency, you simultaneously sell another. Understanding how currency pairs work is the foundation of forex trading.
Reading a Currency Pair
Every currency pair has two components:
- Base currency: The first currency in the pair (left side)
- Quote currency: The second currency (right side)
For example, in EUR/USD = 1.0850, the base is EUR and the quote is USD. This price means 1 Euro costs 1.0850 US Dollars. If you buy EUR/USD, you expect the Euro to strengthen against the Dollar.
Types of Currency Pairs
Major Pairs: Include the US Dollar and the most traded currencies globally. They have the highest liquidity and tightest spreads:
- EUR/USD (Euro / US Dollar) -- most traded pair globally
- 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 (Cross) Pairs: Do not include the US Dollar but involve other major currencies. They have moderate liquidity:
- EUR/GBP, EUR/JPY, GBP/JPY, EUR/AUD, GBP/AUD, EUR/CHF
Exotic Pairs: Pair a major currency with a developing economy's currency. They have wider spreads and lower liquidity:
- USD/TRY (Turkish Lira), EUR/ZAR (South African Rand), USD/MXN (Mexican Peso), USD/SGD (Singapore Dollar)
What Makes Currencies Move?
- Interest rate differentials: Higher interest rates attract foreign capital, strengthening the currency
- Economic performance: Strong GDP, employment, and trade data support a currency
- Political stability: Political uncertainty weakens a currency
- Commodity prices: AUD, CAD, and NZD are linked to commodity exports
- Risk sentiment: JPY and CHF strengthen during global risk-off events
Correlation Between Pairs
Some currency pairs move in similar directions (positive correlation), while others move in opposite directions (negative correlation). For example:
- EUR/USD and GBP/USD are positively correlated (both strengthen when USD weakens)
- EUR/USD and USD/CHF are negatively correlated
Understanding correlations helps avoid overexposure. If you have simultaneous long positions in EUR/USD and GBP/USD, you essentially have double exposure to USD weakness.
Tips for Beginners
Start with major pairs due to their tighter spreads and more predictable behavior. Focus on 2-3 pairs to develop expertise before expanding. Monitor the economic calendars for the currencies you trade. Exotic pairs can be profitable but require more advanced risk management due to higher volatility and wider spreads.
