In 2026, several countries around the world continue to operate without a national currency of their own, relying instead on foreign currencies such as the US dollar or the euro to conduct daily financial transactions. These arrangements stem from a variety of circumstances, including past economic crises, close economic integration with larger neighbours, or a desire for monetary stability. According to Vanguard, the primary trade-off for these countries is the loss of independent monetary policy.
Countries Using the US Dollar
El Salvador replaced its former currency, the colón, with the US dollar in 2001. The government implemented the change to curb inflation, attract foreign investment, and simplify trade and remittances. However, the country cannot independently adjust interest rates or address local economic pressures through its own central bank.
Ecuador adopted the US dollar in 2000, following a severe financial crisis that caused the value of its currency, the sucre, to plummet. Dollarisation helped restore public confidence and brought price stability, but Ecuador relinquished its ability to issue money or set its own monetary policy.
European Countries Using Foreign Currencies
Kosovo uses the euro as its official currency, despite not being a member of the European Union or the eurozone. The country turned to the euro after years of monetary instability and continued its use after declaring independence from Serbia in 2008. While the euro has facilitated trade with European partners, Kosovo has no representation at the European Central Bank and no influence over eurozone monetary decisions.
Montenegro also uses the euro, beginning in 2002, after a transitional period when it used the German mark alongside the Yugoslav dinar. The euro has simplified transactions with European markets and provided a stable monetary environment, but Montenegro cannot issue its own currency or set interest rates independently.
Liechtenstein, a small principality in central Europe, uses the Swiss franc rather than the euro. Its close economic relationship with Switzerland makes this arrangement practical, granting access to one of the world's most stable currencies without maintaining its own. The limitation is that Liechtenstein has little influence over Swiss National Bank decisions.
Impact on Monetary Sovereignty
For all five countries, the absence of a national currency means a loss of control over monetary policy. They cannot print money, set interest rates, or respond to domestic economic shocks through currency adjustments. This can lead to economic stability but also limits their ability to manage inflation, unemployment, or growth independently.
As of 2026, these arrangements remain in place, with no immediate plans for the countries to introduce their own currencies. The reliance on foreign currencies continues to shape their economic policies and international relations.
