Definition
A reserve currency is a currency used by central banks and major financial institutions as part of their foreign exchange reserves. To be suitable for use as reserves, a currency needs to be convertible and should come from a large country with a reputation for low inflation. The principal currency currently used as reserves is the US dollar. Historically, the pound sterling was used as a reserve currency, primarily by sterling area countries, and the French franc has been utilized, mainly by francophone countries. The euro is becoming increasingly popular as a reserve currency.
Historical Context
The concept of a reserve currency dates back to the use of the British pound sterling during the 19th and early 20th centuries, when the British Empire’s economic dominance facilitated its currency’s widespread acceptance. The aftermath of World War II and the Bretton Woods Agreement in 1944 established the US dollar as the predominant reserve currency, a status that continues to this day.
