The major currency pairs are the most traded and liquid pairs in the foreign exchange (Forex) market. They always include the US Dollar (USD) and are paired with other major currencies from economically significant countries.
The major currency pairs are:
EUR/USD (Euro / US Dollar)
USD/JPY (US Dollar / Japanese Yen)
GBP/USD (British Pound / US Dollar)
USD/CHF (US Dollar / Swiss Franc)
AUD/USD (Australian Dollar / US Dollar)
USD/CAD (US Dollar / Canadian Dollar)
NZD/USD (New Zealand Dollar / US Dollar)
These pairs are important because they are highly liquid, meaning they are easier to trade with smaller bid-ask spreads. They also tend to have more predictable price movements due to the large volume of transactions and the economic stability of the countries involved
