In plain English
What Major currency pair means
Major pairs are the most actively traded currency combinations in the spot FX market. They usually include the U.S. dollar on one side and another highly traded currency such as the euro, yen, pound, Swiss franc, Canadian dollar, Australian dollar, or New Zealand dollar. The BIS identifies the dollar as being on one side of most FX trades, and the top traded pairs all involve USD.
Why it matters
Majors often have tighter spreads and deeper liquidity than less traded pairs, which can affect execution quality and trading costs. They are also the benchmark pairs used in much FX analysis and pricing. Even so, liquidity can change by session and market conditions, so majors are not risk-free or cost-free to trade.
Example
EUR/USD, USD/JPY, GBP/USD, and USD/CHF are major pairs. If EUR/USD is quoted at 1.1000/1.1001, the 0.0001 difference is the spread. This is simplified; spreads and available size vary by venue and time of day.
