Currency Pair
How to Read a Currency Pair
Every currency pair has two components:
- Base currency (left): The currency you’re buying or selling. In EUR/USD, the euro is the base.
- Quote currency (right): The price of one unit of the base currency, expressed in this currency. In EUR/USD at 1.0850, you pay $1.085 for 1 euro.
If EUR/USD moves from 1.0850 to 1.0950, the euro has strengthened (or the dollar has weakened). If you bought the pair, you profited. If you sold it, you lost.
Types of Currency Pairs
Major Pairs
The seven most traded pairs — all include the US dollar on one side. They account for roughly 80% of global forex volume.
| Pair | Nickname | Currencies | Typical Spread |
|---|---|---|---|
| EUR/USD | Fiber | Euro / US Dollar | 0.5–1.5 pips |
| USD/JPY | Gopher | US Dollar / Japanese Yen | 0.5–1.5 pips |
| GBP/USD | Cable | British Pound / US Dollar | 1.0–2.0 pips |
| USD/CHF | Swissy | US Dollar / Swiss Franc | 1.0–2.5 pips |
| AUD/USD | Aussie | Australian Dollar / US Dollar | 1.0–2.0 pips |
| USD/CAD | Loonie | US Dollar / Canadian Dollar | 1.5–2.5 pips |
| NZD/USD | Kiwi | New Zealand Dollar / US Dollar | 1.5–3.0 pips |
Minor Pairs (Crosses)
Pairs that don’t include the US dollar. They’re liquid but trade with wider spreads than majors.
| Pair | Currencies | Character |
|---|---|---|
| EUR/GBP | Euro / British Pound | Often range-bound; popular for mean reversion |
| EUR/JPY | Euro / Japanese Yen | Risk sentiment proxy; volatile during market stress |
| GBP/JPY | Pound / Japanese Yen | Known as “the beast” for its wide daily ranges |
| AUD/JPY | Australian Dollar / Yen | Classic carry trade pair; risk-on/risk-off barometer |
| EUR/CHF | Euro / Swiss Franc | Historically stable; Swiss National Bank interventions add event risk |
Exotic Pairs
A major currency paired with a currency from a developing or smaller economy. Higher spreads, lower liquidity, and more volatility.
| Pair | Currencies | Key Consideration |
|---|---|---|
| USD/TRY | US Dollar / Turkish Lira | High volatility; sensitive to Turkish politics and central bank policy |
| USD/ZAR | US Dollar / South African Rand | Commodity-linked; tracks gold and risk sentiment |
| USD/MXN | US Dollar / Mexican Peso | Popular carry trade; US-Mexico trade flows influence pricing |
| EUR/PLN | Euro / Polish Zloty | EU integration dynamics; ECB-NBP policy divergence |
What Moves Currency Pairs
| Driver | Mechanism |
|---|---|
| Interest Rate Differentials | Higher rates attract capital inflows, strengthening the currency. The single most important long-term driver. |
| Economic Data | GDP, employment, inflation reports shift expectations about future monetary policy |
| Central Bank Actions | Rate decisions, forward guidance, and quantitative programs directly impact currency valuation |
| Risk Sentiment | Risk-on favors commodity currencies (AUD, NZD); risk-off favors safe havens (USD, JPY, CHF) |
| Trade Flows | Trade surplus countries see currency demand as foreigners buy their goods |
| Geopolitics | Elections, conflicts, sanctions — particularly impactful for emerging market currencies |
Bid, Ask, and Spread
Every currency pair is quoted with two prices:
- Bid: The price at which you can sell the base currency (what the market maker will pay).
- Ask (Offer): The price at which you can buy the base currency (what you’ll pay).
- Spread: The difference between bid and ask. This is your transaction cost. Major pairs have the tightest spreads; exotics have the widest.
Key Takeaways
- Currency pairs show the exchange rate between two currencies — base (left) vs. quote (right).
- Majors (EUR/USD, USD/JPY, etc.) offer the best liquidity and tightest spreads; exotics are riskier and costlier to trade.
- Interest rate differentials are the dominant long-term driver of currency pair pricing.
- The bid-ask spread is your cost of trading — always factor it into your analysis.
- Cross pairs (minors) let you express views on relative economies without involving the US dollar.
Frequently Asked Questions
What is a currency pair?
A currency pair is a price quote showing how much of one currency is needed to buy one unit of another. For example, EUR/USD at 1.0850 means 1 euro costs 1.085 US dollars. Every forex trade involves simultaneously buying one currency and selling the other.
What is the most traded currency pair?
EUR/USD is the most traded currency pair in the world, accounting for roughly 23% of all forex volume. It offers the tightest spreads and deepest liquidity of any FX instrument. USD/JPY and GBP/USD are the second and third most traded.
What’s the difference between major, minor, and exotic pairs?
Major pairs all include the US dollar and are the most liquid (EUR/USD, USD/JPY, etc.). Minor pairs (crosses) are two major currencies without USD (EUR/GBP, AUD/JPY). Exotic pairs combine a major currency with an emerging market currency (USD/TRY, USD/ZAR) — they’re less liquid and more volatile.
What is a pip in forex?
A pip (percentage in point) is the smallest standard price movement in a currency pair — typically the fourth decimal place (0.0001). For yen pairs, it’s the second decimal (0.01). If EUR/USD moves from 1.0850 to 1.0851, that’s a 1-pip move. One pip on a standard lot (100,000 units) of EUR/USD is worth about $10.
Why do some currency pairs move together?
Correlated pairs share common drivers. EUR/USD and GBP/USD often move together because both are “anti-dollar” trades — when USD weakens, both tend to rise. AUD/USD and NZD/USD correlate because both economies are commodity-dependent and in the same region. Understanding correlations helps avoid accidentally doubling up on the same directional bet.
