The currency of Ecuador is the United States dollar (USD). Ecuador adopted the U.S. dollar as its official currency in the year 2000 as a measure to stabilize its economy, which had been struggling with inflation and banking crises. This move has facilitated trade and investment, making it easier for Ecuadorians to conduct business with other countries that use the dollar. As a result, prices in Ecuador are typically quoted in dollars, and the economy has somewhat stabilized due to this dollarization policy.
