Yes, absolutely. Since 2001, El Salvador has officially adopted the United States dollar (USD) as its legal tender, replacing the former national currency, the Salvadoran colón.
The decision, enacted under President Francisco Flores, was driven by a desire to:
Today, the US dollar is used for all transactions—from buying a pupusa at a street stall to major real estate deals. Prices are posted in dollars. There is no need to exchange currency when traveling from the US. The country does not print its own banknotes; it uses US Federal Reserve notes. Coins in circulation are a mix of US coins and Salvadoran centavo coins (pegged 1:1 to US cents), though the latter are less common.
While dollarization brought macroeconomic stability, it also means El Salvador has no independent monetary policy (cannot devalue currency or set interest rates) and is exposed to US monetary shifts. The move remains a subject of debate among economists.
