reservecurrency

A reserve currency is a foreign currency held in significant quantities by central banks or monetary authorities as a part of their foreign exchange reserves. It is a currency that is widely accepted for international transactions. Typically, a reserve currency is the currency of a major global economy, characterized by its stability, liquidity, and broad acceptance in international trade and finance.

The United States dollar is the most prominent reserve currency in the world today, though the Euro also plays a significant role. Other currencies that have historically served or currently serve as reserve currencies include the British pound sterling, the Japanese yen, and the Swiss franc. The dominance of a reserve currency can influence global trade, investment flows, and the monetary policy of the issuing nation.

The selection of a currency as a reserve currency is not officially designated but rather an emergent property based on its widespread use. Factors contributing to a currency's reserve status include the size and strength of the issuing country's economy, its political stability, the depth and liquidity of its financial markets, and the confidence in its monetary policy. Central banks hold reserves to manage exchange rates, facilitate international trade and payments, and as a buffer against economic shocks.
