Decoding Currency Pairs - Majors, Minors & Exotics
In Forex you never trade a single currency in isolation-you’re always swapping one for another. Think of it like ordering a coffee in Europe and paying in US Dollars: the café must convert USD → EUR, and that rate is a currency pair!
Anatomy of a Pair
Every pair is written BASE/QUOTE. The price tells you how many units of the quote currency
you need to buy one unit of the base.
EUR/USD = 1.0950 → It costs $1.0950 (quote) to buy €1 (base)
If that price rises to 1.1000, the euro strengthened vs the dollar (or the dollar weakened vs the euro).
Majors 🌍
Include the U.S. Dollar and boast huge liquidity & razor-thin spreads.
- EUR/USD (Euro-Dollar)
- GBP/USD (Cable)
- USD/JPY (Dollar-Yen)
- USD/CHF (Swissy)
- AUD/USD · NZD/USD · USD/CAD
Minors (Crosses) 🔄
Pairs without the USD. Liquidity is still decent, spreads a tad wider.
- EUR/GBP · EUR/JPY · GBP/JPY
- AUD/JPY · CHF/JPY
- EUR/AUD · GBP/CAD …
Exotics 🐅
Major currency vs an emerging-market one. Spreads can be chunky & volatility spicy-handle with care!
- USD/TRY (Turkish Lira)
- USD/ZAR (South African Rand)
- EUR/MXN · USD/THB …
Most-Traded Pairs by Volume
Here’s a cheat sheet based on the latest BIS survey (shares rounded):
| Pair | Nickname | Share of Daily Volume |
|---|---|---|
| EUR/USD | Fiber | ~28 % |
| USD/JPY | Gopher | ~13 % |
| GBP/USD | Cable | ~11 % |
| AUD/USD | Aussie | ~7 % |
| USD/CAD | Loonie | ~5 % |
Liquidity peaks during the London–New York overlap, so majors often have spreads as low as 0.1 pip on ECN accounts. Crosses & exotics widen outside their home sessions.
Trader tip: base/quote order matters! If you think the Japanese yen will weaken vs the dollar,
you’d buy USD/JPY. Flipping it to JPY/USD (rarely quoted) would be a completely different trade.
