Agriculturally and thinly populated, Argentina recorded trade surpluses for most of the period between 1900 and 1948, including a cumulative US$1 billion during World War I and US$1.7 billion during World War II. Record taxes on grain exports imposed by the administration of President Juan Perón and an increasing need for costly fuel and machinery helped result in a nearly-unbroken string of trade deficits between 1949 and 1962, however.
Perón and, most notably, the administration of President Arturo Frondizi, encouraged foreign (as well as local) investment in energy and industry as part of a developmentalist policy of import substitution industrialization. Drawn to an economy that provided Latin America's highest standard of living, domestic and foreign investors responded, industrial production more than doubled, and the country's trade position remained modestly positive throughout the 1963–79 era, even as domestic demand grew.
Argentina throughout its history has always depended on foreign trade to achieve a solid economic and social growth. Argentina developed an agro-export model where they were highly dependent on the external sector. The country used to export all their commodities to a growing population of Europe. After this, Argentina started a new period of import substitution where the idea was to reach an industrialized nation. After several military governments, and highly instability periods as hyperinflation and the commercial liberalization of the nineties, Argentina had it worst crisis in 2001.
Policies of "free trade" financial deregulation pursued by Argentina's last dictatorship led to a sudden, record deficit in 1980 and, by 1981, a mountain of bad debts and financial collapse. The climate of slack domestic demand that prevailed in Argentina throughout the 1980s resulted in a cumulative US$38 billion in surpluses from 1982 to 1991; this brought the economy little direct benefit, however, as much of this was deposited abroad during that era of interest payment burdens and financial instability.
Economy Minister Domingo Cavallo enacted the Convertibility Law of 1991, pegging the monetary value of the Argentine peso to the United States dollar. The fixed exchange rate (1 peso to the dollar) allowed for a macroeconomic stabilization. Taking advantage of this low exchange rate, on the lower tariffs on imports and on the reappearance of credit after the free trade liberalization measures taken by President Carlos Menem's administration, Argentine firms and consumers tripled capital goods purchases from 1990 to 1994, while depressed auto sales rose by fivefold. The influx of imported machines and supplies helped the modernization of the country's industrial base; but it negatively impacted its trade balance, which accumulated US$22 billion in deficits from 1992 to 1999; the current account deficit, which would include growing foreign debt interest payments and deficits in trade in services, reached a record deficit of US$14 billion in 1998 alone.
