The dollar did not spread through Argentina only as capital flight by the wealthy. It spread downward and outward until wage earners, retirees and small savers used it as a routine savings tool. Its ordinariness came from mass participation in everyday practices, not from a few large transactions.
Treat money as a set of meanings, practices and institutions, not a neutral medium of exchange. Seen this way, the dollar in Argentina works as a measure of the country's political health, a sign of household prudence and a tool of national self-interpretation. This explains why its price makes headlines and dinner-table conversation, not just market reports.
The parallel 'blue' exchange rate appeared under currency controls and became a widely quoted, openly known price despite being informal. Media, ordinary people and businesses track it as the 'real' value of the peso. Its daily quotation turns an illegal market into shared public information that shapes expectations and prices.
Since the late 1970s, Argentine flats have been listed, negotiated and settled in US dollars, often with physical bills counted at closing. Dollar pricing began as a hedge against inflation and hardened into a convention that buyers, sellers, notaries and banks all expect. This locks housing access to dollar savings and keeps demand for physical bills high.
Hyperinflation, devaluations, the 1989 and 2001 crises and the corralito bank freeze taught Argentines to read exchange rates, time conversions and distrust bank deposits. Ordinary people built a practical financial literacy centred on the dollar. That learned know-how then became a durable habit passed across generations, independent of any single crisis.
Holding physical dollar bills at home or in safe-deposit boxes, outside the banking system, is a rational response to past deposit freezes and confiscations. The bills protect against both the peso and the banks. This hoarding explains Argentina's unusually high per-capita holdings of US banknotes and limits how well domestic monetary policy works.
