Domestic currency refers to the money that a country uses for most economic transactions within its borders. It serves as the official medium of exchange, a unit of account, and a store of value for residents and businesses. In most jurisdictions, the domestic currency is issued by the central bank or monetary authority and is a fiat currency—the value of the notes and coins comes from government decree and public confidence rather than a physical backing. It is designated as legal tender, meaning it must be accepted to settle debts and tax obligations within the country.

The central bank manages the domestic currency through monetary policy, influencing the money supply, interest rates, and credit conditions to maintain price stability and support economic growth. The currency’s value is affected by macroeconomic fundamentals, market expectations, and policy choices. Countries may adopt different exchange rate regimes, from floating to fixed or pegged arrangements, and may impose capital controls or other measures affecting currency transactions.

In practice, some economies experience currency substitution or dollarization, where residents use foreign currencies alongside or instead of the domestic currency. This can occur during periods of high inflation or financial stress and can reflect shifts in confidence or competitiveness. Examples include the United States with the US dollar as its domestic currency, euro-area countries using the euro, and nations that maintain separate currencies such as the British pound or Japanese yen.
