currency pair

This term is a specialized technical expression used almost exclusively within the context of foreign exchange (forex) trading. It describes the relationship between two currencies, where the first is the base currency and the second is the quote currency. The value represents how much of the quote currency is needed to purchase one unit of the base currency.

In professional trading, these are often categorized as majors, minors, or exotics based on the liquidity and importance of the currencies involved. Because it is a compound noun, it follows standard English pluralization rules, though it is rarely used in the singular when discussing general market trends.
