What Is a Currency Pair?

In the foreign exchange market, currencies are always traded in pairs. When you trade EUR/USD, for example, you're simultaneously buying euros and selling US dollars (or vice versa). Every forex trade involves exchanging one currency for another, which is why they come in pairs.

The first currency in the pair is called the base currency, and the second is the quote currency. The price of EUR/USD at 1.0850 means 1 euro buys 1.0850 US dollars.

The Three Types of Currency Pairs

Majors

Major pairs always include the US dollar and are the most traded pairs in the world. They typically have the tightest spreads (lowest trading costs) and the most liquidity.

  • EUR/USD – Euro / US Dollar
  • 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

Minors (Cross Pairs)

Minor pairs don't include the US dollar but involve other major currencies. Examples include EUR/GBP, EUR/JPY, and GBP/JPY. They tend to have slightly wider spreads than majors but still offer solid liquidity.

Exotics

Exotic pairs combine a major currency with a currency from an emerging or smaller economy — like USD/TRY (US Dollar / Turkish Lira) or EUR/ZAR (Euro / South African Rand). These pairs have much wider spreads and can be highly volatile. They're not recommended for beginners.

What Is a Pip?

A pip (Percentage in Point) is the smallest standard price move in a currency pair. For most pairs, a pip is the fourth decimal place — so a move from 1.0850 to 1.0851 is one pip. For USD/JPY, a pip is the second decimal place.

Understanding pips matters because your profit and loss are measured in them. If you buy EUR/USD and it moves 50 pips in your favor, your gain depends on your position size (lot size).

What Moves Currency Pairs?

Currency prices are driven by a range of factors:

  • Interest rates: Higher interest rates attract foreign capital, strengthening a currency. Central bank decisions (from the Fed, ECB, Bank of England, etc.) are the most market-moving events in forex.
  • Economic data: Reports like GDP, inflation (CPI), employment figures, and retail sales all influence currency strength.
  • Geopolitical events: Political instability, elections, and global conflicts create volatility.
  • Market sentiment: Risk-on and risk-off environments shift demand for certain currencies (e.g., JPY and CHF are seen as "safe havens").

Which Pair Should You Start With?

For beginners, EUR/USD is almost always recommended as the starting point. Here's why:

  • It's the most traded pair in the world — maximum liquidity.
  • Spreads are extremely tight, reducing your trading costs.
  • Plenty of free analysis, news, and educational content is available for it.
  • It's relatively predictable compared to exotic or even some minor pairs.

Once you're comfortable with EUR/USD, you can explore GBP/USD and USD/JPY — both are highly liquid and offer excellent trading opportunities.

Key Takeaways

  • Forex trades always involve two currencies — a base and a quote.
  • Stick to major pairs when starting out for better liquidity and lower costs.
  • Understand what moves the pairs you trade: interest rates and economic data are the biggest drivers.
  • Learn to calculate pip value so you can properly size your positions and manage risk.

The forex market offers enormous opportunity — but it rewards those who take the time to understand its fundamentals before risking real money.
