Ecuador adopted the US dollar to escape its currency collapse

By late 1999 Ecuador's currency, the sucre, was in freefall: inflation had climbed toward 60-90%, the banking system had collapsed with deposits frozen, the country had defaulted on its sovereign debt, and output had shrunk more than 7% in a single year. Every standard central-bank tool — interest rate moves, currency interventions, promises of reform — depended on a public that had already stopped believing the sucre or the institutions defending it would hold.

President Jamil Mahuad, who days earlier had called the idea 'a jump into the abyss,' recognized that no incremental fix could restore trust fast enough to stop the collapse, because the problem wasn't a specific policy error but the currency's credibility itself. The alternative was radical: stop defending the sucre and eliminate it, converting the country's money supply directly into US dollars.

On January 9, 2000, Mahuad announced dollarization: Ecuador would abolish the sucre and adopt the US dollar as its sole legal tender, converting existing sucres at a fixed rate of 25,000 to the dollar. The move surrendered Ecuador's monetary sovereignty entirely — no more independent interest-rate policy, no ability to print money or devalue — in exchange for immediately importing the credibility of the world's reserve currency instead of trying to rebuild trust in a currency the public had already given up on.

Abolished the sucre and adopted the US dollar, importing the dollar's credibility instead of rebuilding trust in a damaged currency.

The sucre's credibility was destroyed, so any policy using it was doomed.

Adopting the dollar imported a stable currency with global trust.

Inflation fell rapidly because the dollar's value didn't depend on Ecuadorian institutions.

The move was politically costly but economically durable, with lasting public support.

When your own system's credibility is beyond repair, abandon it and adopt an external trusted standard instead of trying to rebuild trust incrementally.

The announcement triggered a political crisis of its own — Mahuad's approval collapsed to single digits and he was forced from office within weeks by indigenous protests and a military uprising — but his successor kept the policy in place. Inflation fell from the 60-90% range to low single digits within a few years, bank deposits that had collapsed during the crisis grew from under $1 billion in 2000 to over $10 billion by 2024, and dollarization became one of the most durable and consistently popular policies in modern Ecuadorian history, with approval near 90% decades later.
