Argentina’s Convertibility Peso — The Anti-Inflation Cure That Became a Trap

Summary

The Argentine convertibility peso is the rare Zero Hour case that died not of too much inflation but of too little flexibility. It was born as the antidote to the hyperinflation chronicled in PP-002 — the austral that disintegrated in 1989, when prices rose roughly 200% in the single month of July and around 5,000% across the year — and for a decade it worked spectacularly. Then, in January 2002, after a sovereign default and a deposit freeze that pried the country's savings out of its own hands, the government repealed the law that had defined the currency and let the peso float. It fell from one-to-one with the US dollar to nearly four-to-one within months. The verdict is Devalued: not a hyperinflation, not a redenomination, but the collapse of a hard peg and the roughly 70–75% depreciation that followed.

The cure had been brutally simple. The Convertibility Law, which took effect on 1 April 1991 under President Carlos Menem and Economy Minister Domingo Cavallo, fixed the currency at one peso to one US dollar and required the central bank to back the monetary base substantially with dollar reserves; in 1992 the peso convertible (ARS) formally replaced the austral at 10,000 australes to one peso. The arrangement functioned as a near-currency-board: the central bank could not simply print to cover deficits, because every peso in circulation had to be answerable to a dollar in the vault. The inflation tax that had defined Argentine life for forty years was abolished by statute. Annual inflation, which had averaged some 600% from 1983 to 1991, fell to about 4.6% a year from 1992 to 1998; for a time, capital poured in and the economy boomed.

The trap was the rigidity itself. A peg that cannot move forces all adjustment onto everything else — wages, prices, employment, output. When the dollar strengthened in the late 1990s, when Brazil devalued its real in 1999, and when commodity prices sagged, Argentine exports priced in expensive dollars became uncompetitive, and a recession that began in the third quarter of 1998 ground on with no exchange-rate escape valve. The government, barred from monetizing its deficits, borrowed instead — and the debt mounted until markets stopped lending. By late 2001 the peg's two preconditions, external financing and fiscal discipline, had both failed.

The end came in weeks. On 1 December 2001 Cavallo imposed the corralito — the "little fence" — capping bank withdrawals at 250 pesos a week to stop a run; meant to save the banks, it detonated the politics. Riots and a revolving door of presidents followed; in late December 2001 Argentina suspended payments on its sovereign debt, the largest default in history to that point (figures range from roughly US$93 billion to as much as US$132 billion depending on what is counted). In early January 2002 President Eduardo Duhalde's government repealed the Convertibility Law and floated the peso. It overshot to nearly four per dollar by mid-2002 — devalued, not abolished, but the decade-long promise of one peso, one dollar was over.

Timeline

The Anchor: Why Argentina Bolted the Door on Its Own Printing Press

To understand why Argentina embraced a straitjacket, one must remember what it was escaping. For four decades the country had been the textbook chronic-deficit case: a state that habitually spent beyond its revenues and a central bank that habitually printed to cover the gap. PP-002 records the climax — the 1989–90 hyperinflation that overwhelmed the austral, when prices rose around 200% in July 1989 alone and Argentines lined up to spend wages before they evaporated. After that trauma, half-measures had no credibility. The country had already burned through the Austral Plan and a string of failed freezes in the late 1980s; Argentines had seen too many stabilization plans launched and abandoned to believe a mere promise of restraint. Only a rule that could not be broken — or so it seemed — could anchor expectations that had been betrayed so many times before.

Convertibility was credibility by amputation. By writing the one-to-one peg into law and requiring the central bank to hold dollars against the pesos it issued, the 1991 reform did not ask Argentines to trust that the government would stop printing; it removed the government's ability to print at will. This was the whole genius of the design and, as it turned out, the whole flaw. A currency board buys instant credibility by surrendering the central bank's most basic tool — the power to set its own monetary conditions. For as long as the dollar suited Argentina's economy, the discipline was a gift; the moment the dollar and the Argentine economy diverged, the country was locked to a monetary policy made in Washington for American conditions.

The Vise: When the Only Variable Left to Move Was People

A pegged economy adjusts by internal deflation: if you cannot cheapen your currency, you must cheapen your wages, your prices, and ultimately your workers. From 1998 the vise tightened. The dollar appreciated; Brazil, Argentina's largest trading partner, devalued the real in 1999, instantly making Brazilian goods cheaper and Argentine exports dearer; commodity prices fell. An economy with a floating currency would have devalued to restore competitiveness. Argentina could not. So adjustment fell on output and jobs: the recession that began in late 1998 deepened into a depression, with the economy shrinking by roughly a quarter from peak to trough and unemployment climbing past 20%.

The fiscal side compounded the bind. Forbidden to monetize its deficits — the very prohibition that had killed inflation — the government financed them by borrowing in dollars. Each year of recession widened the deficit and the debt, and each increment of debt raised the interest rate Argentina had to pay, which widened the deficit again. By 2001 the country was paying punishing risk premiums to roll over obligations it plainly could not service at a fixed exchange rate. Convertibility had abolished the inflation tax but left the underlying disease untreated; it had merely changed the currency of the reckoning from printed pesos to borrowed dollars.

The Five Factors

Aftermath

The float, paradoxically, worked better than its architects feared. Freed of the overvalued peg, Argentine exports regained competitiveness; the feared hyperinflationary spiral never came, with 2002 inflation at about 41% rather than the triple digits some predicted. The peso settled near three to the dollar, GDP growth resumed by mid-2003, and the economy expanded briskly for several years on the back of high commodity prices. In that narrow sense the devaluation was a release, not a catastrophe — which is why the verdict is Devalued, a currency that survived its fall, and not Repudiated.

The costs landed hardest on ordinary holders. The corralito impounded household savings; the pesification then converted dollar deposits into pesos worth far less, transferring wealth from savers to debtors by decree. Poverty climbed above 50% at the depth of the crisis, and the default locked Argentina out of international credit markets for years. The deeper legacy is psychological: Argentines learned, again, that neither the peso nor the banks that hold it can be trusted, a folk memory that drives the country's enduring flight into dollars. PP-002 told how deficit monetization birthed the peg; this file is its bookend — the story of how the cure for one disease became the cause of the next, because no exchange-rate regime, however clever, can substitute for a government that will not balance its books.
