A reserve currency is a currency that is held in significant quantities by governments and institutions as part of their foreign exchange reserves. This currency is typically used for international transactions, investments, and all aspects of the global economy. Reserve currencies provide countries with a cushion of liquidity in the case of economic instability and also help to reduce exchange rate risk.
Historical Context
Evolution of Reserve Currencies
The concept of a reserve currency dates back to the early 20th century. The British Pound Sterling was the leading reserve currency before World War II. Post-war, the United States Dollar (USD) emerged as the primary reserve currency, a status solidified by the Bretton Woods Agreement in 1944.
Key Characteristics
Stability
A reserve currency must exhibit considerable stability. Countries and institutions prefer to hold reserves in currencies that maintain their value over time.
Liquidity
The currency should be highly liquid, meaning it can be easily bought and sold without causing significant price changes.
Economic Strength
The currency is usually issued by a country with a robust and stable economy, often featuring low inflation and strong legal and financial institutions.
Types of Reserve Currencies
Primary Reserve Currency
The USD currently serves as the primary reserve currency, accounting for approximately 60% of global reserves as of 2021.
Secondary Reserve Currencies
Other currencies held in smaller quantities include the Euro (EUR), Japanese Yen (JPY), British Pound Sterling (GBP), and the Chinese Yuan (CNY).
Applicability

Comparisons
Reserve Currency vs. Local Currency
Unlike a local currency, used mainly within a specific country, a reserve currency is used globally for international transactions and reserves.
Reserve Currency vs. Commodity Money
Commodity money like gold or silver has intrinsic value, whereas reserve currencies do not; they derive value from the economic strength and stability of the issuing country.
