What Is Reserve Currency?
A reserve currency is a currency held in large quantities by governments and central banks as part of their foreign exchange reserves, used for international trade settlement, debt issuance, and as a store of value. The U.S. dollar has been the world's dominant reserve currency since the Bretton Woods Agreement of 1944, currently comprising approximately 58% of global foreign exchange reserves. Other reserve currencies include the euro (~20%), Japanese yen (~5%), British pound (~5%), and Chinese renminbi (~2.5%). Reserve currency status confers significant advantages ("exorbitant privilege"): the issuing country can borrow at lower interest rates, run persistent trade deficits, and exercise financial influence globally. However, it also brings challenges including currency appreciation that can hurt export competitiveness. De-dollarization discussions have intensified as geopolitical tensions and sanctions motivate some countries to diversify away from dollar-denominated reserves.
Reserve Currency Example
- 1The U.S. dollar accounts for approximately 58% of global foreign exchange reserves, down from 72% in 2000 but still dominant.
- 2China has been promoting the renminbi as a reserve currency through bilateral swap agreements and its inclusion in the IMF's SDR basket in 2016.
- 3The "exorbitant privilege" of reserve currency status allows the U.S. to borrow at lower rates than its fiscal position might otherwise warrant.
