Definition ∞ A reserve currency is a foreign currency held in significant quantities by central banks and financial institutions as part of their foreign exchange reserves. It is typically used for international transactions, investments, and as a benchmark for global trade, signifying its stability and widespread acceptance. The US dollar has historically served as the primary global reserve currency due to the size and stability of the American economy. Its status grants the issuing country significant economic influence on the global stage.
Context ∞ Discussions around reserve currency status are gaining relevance in the digital asset space as nations consider the potential for central bank digital currencies (CBDCs) or major cryptocurrencies to challenge existing fiat dominance. Geopolitical shifts and economic policies influence the perceived stability and utility of traditional reserve currencies. News often reports on countries diversifying their reserves or debating the future role of various currencies in international finance.
