Which Countries Use the US Dollar as Their Official Currency?
Six sovereign countries have fully replaced their national currency with the US dollar: Ecuador, El Salvador, East Timor, the Marshall Islands, Micronesia, and Palau. A seventh, Panama, uses US dollar bills as its everyday cash while keeping its own balboa, pegged 1:1, mostly for coins.
Countries Officially Using the US Dollar
| Country | Adopted | Why |
|---|---|---|
| Panama | 1904 | The balboa was pegged 1:1 to the dollar at independence; US bills became the everyday cash |
| Ecuador | 2000 | Adopted the dollar after hyperinflation destroyed the sucre |
| El Salvador | 2001 | Adopted the dollar to stabilize the economy and cut currency-exchange costs with the US |
| East Timor | 2002 | Adopted the dollar at independence from Indonesia; still mints its own centavo coins |
| Marshall Islands | 1944 | Used the dollar since US administration; never introduced its own currency |
| Micronesia | 1944 | Same arrangement as the Marshall Islands, formalized at independence |
| Palau | 1994 | Same arrangement, formalized at independence from the US-administered trust territory |
Why Do Countries Give Up Their Own Currency?
The most common reason is hyperinflation. A national currency that has collapsed in value stops functioning as a reliable store of value, and switching to a stable foreign currency, usually the dollar, restores confidence in prices overnight. For very small economies, there's also a simpler reason: running an independent central bank and monetary policy isn't worth the cost when the economy is tiny and closely tied to the US.
The Case of Ecuador
In 1999 and 2000, Ecuador's sucre lost roughly two-thirds of its value amid a banking crisis. The government adopted the US dollar in 2000 to halt the collapse. It worked: inflation fell sharply within a few years. Ecuador still mints its own coins, sized and weighted to match US coins, so both circulate side by side.

Zimbabwe adopted the US dollar in 2009 after one of the worst hyperinflations in recorded history wiped out its own currency's value. US dollars became the dominant currency in daily use for years. In 2024, Zimbabwe introduced a new official currency, the ZiG (Zimbabwe Gold), backed by gold and foreign reserves, though US dollars still circulate widely alongside it.

Pegging means a country keeps its own currency but fixes its exchange rate to the dollar, as Panama does with the balboa and Hong Kong does with the Hong Kong dollar. Full dollarization means the national currency is abolished entirely and the US dollar becomes legal tender in its place, as in Ecuador and El Salvador. Pegged currencies can, in theory, be unpegged; dollarization is much harder to reverse.
