Argentine peso (ARS): overview, history and contemporary use

Denominations and design

Modern banknotes and coins show national symbols, notable historical figures and cultural imagery. Frequent redesigns have been used to improve security and to introduce higher denominations when inflation reduces the purchasing power of existing notes. Coins for small values remain part of the monetary system but their circulation and practical use vary with price levels and consumer habits.

History and major reforms

Argentina's monetary history includes several distinct currency units across the 20th and early 21st centuries. In the mid-1980s the austral replaced an older peso and was itself replaced in the early 1990s by a new peso introduced under a convertibility regime. The 1991 convertibility plan tied one peso to one U.S. dollar and aimed to control inflation through a currency board–like arrangement. That peg ended during the economic crisis of 2001–2002, after which the peso was allowed to float and experienced sharp devaluations and renewed inflationary pressures.

Convertibility era and aftermath

The convertibility period brought stability and a fixed exchange rate for about a decade, but it also limited monetary flexibility. Following the end of convertibility, fiscal and monetary adjustments, capital controls and recurring inflation episodes shaped subsequent policy. Since then, the peso has been subject to periodic depreciation against major foreign currencies and occasional episodes of rapid price increases.

Exchange rates and parallel markets

Argentina is notable for having multiple exchange-rate references in practice. In addition to the official rate set by authorities, there have frequently been parallel or informal rates used by individuals and businesses. These include a street or “blue” rate for cash dollars and market-based rates obtained through financial instruments such as the MEP and contado con liquidación operations. Such parallel rates reflect differences in access to foreign currency and regulatory conditions.

Everyday use and economic impact

The peso is used for wages, retail purchases, services and domestic contracts. For many Argentines, holding or pricing some savings and assets in U.S. dollars is common as a hedge against inflation. This dual use affects consumer behavior, contract terms and the operation of banks and financial markets. Inflation influences which denominations are practical for daily transactions and how frequently banknotes are redesigned or replaced.
