Currency pairs: majors, minors and exotics

Educational content, not investment advice. Nour explains how markets work. She never tells you what to buy or sell.
In forex you always buy one currency and sell another at the same time, so currencies are quoted in pairs.
- The first currency is the base, the second is the quote: EUR/USD at 1.1000 means 1 euro = 1.10 dollars.
- Majors pair the US dollar with another major currency; the dollar was on one side of about 89% of trades in April 2025 (BIS).
- Minors (crosses) pair major currencies without the dollar; spreads are usually a little wider.
- Exotics involve smaller or emerging-market currencies: lower volume, wider spreads, sharper jumps.
- Five trades that all buy the dollar are really one bet.
