Major currency pairs refer to the six most actively traded currency pairs:

AUD/USD - Australian dollar against the US dollar

• EUR/USD - EUR/USD

• GBP/USD - GBP/USD

• USD/CAD - USD/CAD

• USD/CHF - USD/CHF

• USD/JPY - USD/JPY
The major forex pairs include currencies from the world's largest economies. One reason their currencies are so active is the vast amount of goods and services they trade.

A second reason is the political and economic stability associated with these currencies. In uncertain economic times, this makes them more appealing.
