The Currency Question

A History Written in Devaluations

No region on earth has had a more turbulent relationship with its own money. Latin America's twentieth century was punctuated by currency collapses so severe they acquired names: the Brazilian cruzeiro gave way to the cruzado, then the cruzado novo, then the real, each redenomination a confession of what came before. Argentina went through so many monetary regimes — the austral, the convertibility peso, the post-2001 wreckage — that its central bank became less an institution than a recurring character in a tragicomedy. Bolivia, in the mid-1980s, recorded annual inflation above ten thousand percent. These were not accidents. They were the consequence of governments that borrowed in foreign currencies, spent beyond their means and, when creditors balked, printed their way out.

The structural driver is familiar to economists: a deep reliance on commodity exports, chronic fiscal deficits and thin local capital markets that could not absorb government debt without demanding steep risk premiums. When commodity prices fell and hard-currency revenues dried up, the pressure on the exchange rate became irresistible. Devaluation followed — which raised the cost of dollar-denominated debt, which deepened the fiscal hole, which raised the pressure further. The cycle repeated with grim regularity through the 1970s, 1980s and 1990s, burning through the savings of anyone holding local currency.

The Dollar's Appeal — and Its Price

The obvious escape was to abandon the local currency altogether. Ecuador did exactly that in 2000, adopting the US dollar after a catastrophic banking crisis and currency collapse. El Salvador followed in 2001. Panama had never really left, using the dollar since 1904. The appeal is straightforward: imported monetary credibility. With no printing press to reach for, inflation becomes a structural rather than a policy choice, interest rates converge toward US levels, and the currency risk that had made long-term investment so difficult simply disappears.

The cost is equally straightforward: you surrender the adjustment mechanism. A dollarised economy that suffers a terms-of-trade shock — say, when oil revenues fall sharply — cannot devalue to restore competitiveness. It must instead accept deflation, wage cuts or unemployment, all of which are politically and socially brutal. Panama has managed this for decades partly because of the canal revenues and its role as a financial hub, which provide hard-currency flows most dollarised economies cannot replicate.

The intermediate strategy — the currency board — produced arguably the region's most spectacular failure. Argentina's convertibility system, which pegged the peso one-to-one to the dollar from 1991 to 2001, delivered a decade of stability before collapsing in the most dramatic sovereign default in history at the time. The peg had been sustainable only as long as capital flowed in; once confidence broke, the architecture fell in days.

Why Currencies Carry Political Weight

For ordinary Latin Americans, the exchange rate is not an abstraction. It is the price of imports, the value of remittances, the purchasing power of a salary. When currencies weaken sharply, savings evaporate — which is why dolarización informal emerged organically in countries like Peru and Uruguay long before any official adoption, with households and businesses denominating contracts and savings in dollars regardless of what the government preferred. The state's monopoly on legal tender became notional in practice.

This is why currency policy in the region is inseparable from political legitimacy. A central bank that holds the line on inflation — Chile's Banco Central, Colombia's Banco de la República, Brazil's Banco Central do Brasil — accumulates credibility slowly over years. A government that raids reserves or pressures the monetary authority for cheap financing can destroy that credibility in weeks. Argentina's long fight with inflation is the extreme case, but it illustrates a tension latent across the region: the temptation to treat the currency as a fiscal tool is always present, and resisting it requires institutions strong enough to say no to the government that created them.
