The Hidden Costs of Dollarization When Countries Abandon Their Own Currency
The Hidden Costs of Dollarization When Countries Abandon Their Own Currency
In times of economic crisis, the US dollar can seem like a lifeline. For countries plagued by hyperinflation, currency crashes, and lost confidence in local institutions, adopting the dollar--official "dollarization"--offers the promise of stability. Prices stop spiraling. Savings regain value. Investors breathe easier.
But this stability comes at a price--one that is rarely visible in the headlines but paid daily by the nations that choose this path. As several countries across Africa and Latin America grapple with dollarization pressures, understanding these hidden costs has never been more urgent.
The Promise: Stability at Last
The appeal of dollarization is straightforward. When a country abandons its own currency, it imports the credibility of the US Federal Reserve. Inflation, often the original crisis trigger, plummets. Interest rates fall. Economic calculations become possible again.
Ecuador's experience offers the most compelling success story. When Ecuador adopted the dollar in 2000, it was in the midst of a catastrophic crisis. Inflation had exceeded 60% annually. The sucre had collapsed from 5,000 to over 25,000 per dollar. Banks were failing. The economy was contracting.
Twenty-five years later, the picture is dramatically different. Inflation has averaged just 3.2% annually since dollarization--down from nearly 40% in the two decades before. Real growth has increased by over 1% per year. Market capitalization in Quito has nearly tripled as a share of GDP. Interest rates on 30-day bank loans fell from 89% in 1999 to 16% just one year later. Today, nearly 90% of Ecuadorians support keeping the dollar.
The Hidden Cost: Seigniorage and Lost Revenue
But stability is not free. The most tangible hidden cost of dollarization is seigniorage--the profit a government makes by issuing currency. When you print a $100 bill that costs 15 cents to produce, you've effectively earned $99.85. That's seigniorage.
Under dollarization, that profit flows not to the local central bank, but to the US Treasury. Ecuador has paid an estimated $20 billion in seigniorage to the United States since dollarizing--accumulated "outside money" in dollar currency and coin. In recent years, the operational cost of seigniorage and the inflationary tax has exceeded 1% of Ecuador's GDP annually.
This is money that cannot fund schools, hospitals, or infrastructure. It is a permanent transfer from a poor country to the world's richest, invisible in trade statistics but real in forgone opportunity.
The Rigidity Trap: No Monetary Policy
Perhaps more consequential is the loss of monetary sovereignty. A dollarized country cannot adjust interest rates to cool an overheating economy or stimulate a slowing one. It cannot print money to finance emergency spending. It cannot devalue to boost exports when the currency becomes overvalued.
Ecuador's Central Bank, once tasked with managing the currency, now has little to do but watch. As former President Rafael Correa once noted, dollarization is "like being in a boxing ring wearing a straitjacket." Yet even Correa, who questioned dollarization, dared not attempt to reverse it--the costs of exit would be catastrophic.
During the 2008 global financial crisis, while other Latin American countries slashed interest rates to stimulate growth, Ecuador could only watch. During the COVID-19 pandemic, while the US Federal Reserve printed trillions to support its economy, Ecuador had no such option. It could only spend what it had or borrow from international markets at punishing rates.
The Lender of Last Resort Vacuum
In a normal financial system, the central bank serves as the "lender of last resort"--providing liquidity to banks facing temporary runs, preventing panic from becoming collapse. Under dollarization, this backstop disappears.
A bank in Kansas can borrow from the Federal Reserve. A bank in Quito cannot. If depositors panic, there is no unlimited dollar printing press to calm them. The only source of liquidity is the country's own dollar reserves, which are finite. This makes banking systems in dollarized economies inherently more fragile.
Ecuador has managed this through careful regulation and international support. But the vulnerability remains, a constant threat that non-dollarized countries do not face. A sudden loss of confidence could trigger a bank run with no lender of last resort to stop it.
The Trap of Irreversibility
Perhaps the most insidious cost is the near impossibility of reversal. Dollarization is not like a currency peg that can be adjusted. It is nearly permanent.
Zimbabwe's tragic history illustrates both why countries dollarize and why they struggle to return. After hyperinflation peaked at an incomprehensible 79.6 billion percent in November 2008, Zimbabwe abandoned its dollar in 2009 and adopted the US currency. For 15 years, the dollar provided stability.
But in 2024, Zimbabwe launched the ZiG (Zimbabwe Gold), a new gold-backed currency, aiming to restore monetary sovereignty by 2030. The results have been devastating. The ZiG lost nearly half its value within a year. On the parallel market, one dollar now exchanges for more than 30 ZiG, compared to 13.5 at launch. Only 40% of transactions are in local currency. The informal economy, already the world's largest, has expanded further. Businesses refuse long-term contracts. Civil servants receive part of their salary in ZiG, which they desperately try to spend before it loses value.
The IMF notes that only four of 85 countries that attempted de-dollarization between 1980 and 2001 succeeded. Zimbabwe's struggle reveals the terrible truth: dollarization may be a trap, but the door closes behind you.
The Geopolitical Price
There is another cost, less discussed but equally real. Dollarization subordinates a country's monetary system to the political decisions of the United States. When Washington imposes sanctions, dollarized countries have no choice but to comply. Their entire financial system is already dollar-denominated, already integrated into the US banking network.
