What Is a Currency Pair? [Understanding currency pairs]

A currency pair compares two currencies, showing how much of the quote currency buys one unit of the base currency.

Base vs. Quote Currency:

  • Base currency: The first currency (the one you buy/sell).
  • Quote currency: The second currency (the pricing benchmark).

Example: In EUR/USD = 1.12:

  • EUR = Base (1 unit)
  • USD = Quote ($1.12 buys €1)

3 Types of Currency Pairs Explained

TypeExamplesVolumeAvg. SpreadKey Trait
MajorsEUR/USD, USD/JPY75%0.1–1.0 pipHigh liquidity
MinorsEUR/GBP, AUD/CAD18%1.0–3.0 pipsLower volatility
ExoticsUSD/ZAR, USD/TRY7%5.0–50 pipsHigh volatility

Why USD/ZAR Stands Out:

  • Avg. daily range: 800 pips (vs. 100 for EUR/USD)
  • Drivers: SA commodity exports, USD strength

How Currency Pairs Are Priced: Bid, Ask & Spread

The Pricing Trio:

  1. Bid Price: What buyers pay for the base currency.
  2. Ask Price: What sellers accept for the base currency.
  3. Spread: Difference between bid/ask (broker’s profit).

USD/ZAR Example:
Bid = 18.50 / Ask = 18.55 → Spread = 0.05 ZAR

Pip Values Simplified:

  • 1 Pip = 0.0001 for most pairs (e.g., EUR/USD from 1.1200 → 1.1201)
  • Exotic Exception: USD/ZAR uses 0.0001 (18.5000 → 18.5001 = 1 pip)

Popular Pairs: Why Traders Choose Them

✅ EUR/USD (The “Fiber”)

  • Why: Tight spreads (0.1–0.5 pips), reacts predictably to Fed/ECB news.
  • Best for: Scalpers, beginners.

💥 USD/ZAR (Volatility King)

  • Why: 12% avg. monthly swings, ideal for breakout strategies.
  • Risk: Wide spreads (15–25 pips) — use limit orders.

Other Key Pairs:

  • GBP/JPY: “Beast” — high momentum during London session.
  • AUD/USD: Tracks iron ore/copper prices.
