Argentine peso

The peso was a name often used for the silver Spanish eight-real coin. Following independence, Argentina began issuing its own coins, denominated in reales, soles and escudos, including silver eight-real (or sol) coins still known as pesos. These coins, together with those from neighbouring countries, circulated until 1881.

In 1826, two paper money issues began, denominated in pesos. One, the peso fuerte ($F) was a convertible currency, with 17 pesos fuertes equal to one Spanish ounce (27.0643 g) of 0.916 fine gold. It was replaced by the peso moneda nacional at par in 1881.

The non-convertible peso moneda corriente (everyday currency) ($m/c) was also introduced in 1826. It started at par with the peso fuerte, but depreciated with time.

Although the Argentine Confederation issued 1-, 2- and 4-centavo coins in 1854, with 100 centavos equal to 1 peso = 8 reales, Argentina did not decimalize until 1881. The peso moneda nacional (m$n or $m/n) replaced the earlier currencies at the rate of 1 peso moneda nacional = 8 reales = 1 peso fuerte = 25 peso moneda corriente. Initially, one peso moneda nacional coin was made of silver and known as patacón. However, the 1890 economic crisis ensured that no further silver coins were issued.

The Argentine gold coin from 1875 was the gold peso fuerte, one and two-thirds of a gram of gold of fineness 900, equivalent to one and a half grams of fine gold, defined by Law no. 733 of 1875. This unit was based on that recommended by the European Congress of Economists in Paris in 1867 and adopted by Japan in 1873 (the Argentine 5 peso fuerte coin was equivalent to the Japanese 5 yen).[5]

The system before 1881 has been described as "monetary anarchism" (anarquía monetaria).[5] Law no. 1130 of 1881 put an end to this; it established the monetary unit as the peso oro sellado ("stamped gold peso"), a coin of 1.612 g of gold of fineness 900 (90%), and the silver peso, 25 g of silver of fineness 900.[5] Gold coins of 5 and 2.5 pesos were to be used, silver coins of one peso and 50, 20, 10 and 5 centavos, and copper coins of 2 and 1 centavos.

The depreciated peso moneda corriente was replaced in 1881 by the paper peso moneda nacional (national currency, (m$n or $m/n)) at a rate of 25 to 1. This currency was used from 1881 until January 1, 1970.[6] The design was changed in 1899 and, again, in 1942.

Initially the peso m$n was convertible, with a value of one peso oro sellado. Convertibility was maintained off and on, with decreasing value in gold, until it was finally abandoned in 1929, when m$n 2.2727 was equivalent to one peso oro.

The peso ley 18.188 (ISO 4217: ARL) (informally called the peso ley) replaced the previous currency at a rate of 1 peso ley to 100 pesos moneda nacional.

The peso argentino ($a) (ISO 4217: ARP) replaced the previous currency at a rate of 1 peso argentino to 10,000 pesos ley (1 million pesos m$n). The currency was born just before the return of democracy, on June 1, 1983. However, it rapidly lost its purchasing power and was devalued several times, and was replaced by a new currency called the austral in June 1985.

The austral ("₳") (ISO 4217: ARA) replaced the peso argentino at a rate of 1 austral to 1,000 pesos (one billion pesos m$n). During the period of circulation of the austral, Argentina suffered from hyperinflation. The last months of President Raul Alfonsín's period in office in 1989 saw prices increase constantly (200% in July alone), reflected in a worsening exchange rate. Emergency notes of 10,000, 50,000 and 500,000 australes were issued, and provincial administrations issued their own currency for the first time in decades. The value of the currency stabilized two years after President Carlos Menem was elected.

In 1992 a new peso (ISO 4217: ARS) was introduced, referred to as peso convertible since the international exchange rate was fixed by the Central Bank at 1 peso to 1 U.S. dollar, and for every peso convertible circulating, there was a US dollar in the Central Bank's foreign currency reserves. It replaced the austral at a rate of 1 peso = 10,000 australes. After the various changes of currency and dropping of zeros, one peso convertible of 1992 was equivalent to 10 trillion pesos moneda nacional of 1970.

After the financial crisis of 2001, the fixed exchange rate system was abandoned in January 2002, and the exchange rate fluctuated, up to a peak of four pesos to one dollar (a 75% devaluation) at the time. The resulting export boom produced a massive inflow of dollars into the Argentine economy, which helped lower their price. For a time the administration stated and maintained a strategy of keeping the exchange rate at between 2.90 and 3.10 pesos per US dollar, in order to maintain the competitiveness of exports and encourage import substitution by local industries. When necessary, the Central Bank issues pesos and buys dollars in the free market (sometimes large amounts, of the order of 10 to US$100 million per day) to keep the dollar price from dropping, and had amassed over US$27 billion in reserves before the US$9.81 billion payment to the International Monetary Fund in January 2006.

The effect of this may be compared to the neighboring Brazilian real, which was roughly on par with the Argentine peso until the beginning of 2003, when both currencies were about three per U.S. dollar. The real started gaining in value more than the peso due to Brazil's slower build-up of dollar reserves; by December 29, 2009, a real was worth almost 2.2 pesos.[7]

In December 2015, US dollar exchange restrictions were removed in Argentina following the election of President Mauricio Macri. As a result, the difference between the official rate and the unofficial "blue" rate almost disappeared for a time.

The official exchange rate was on April 1, 2016, 14.4 to US$1.[8] The rate gradually worsened; on 29 July 2022 one U.S. dollar was quoted at 131.22 pesos at the official rate and 298 pesos, 2.27 times higher (+127%), in unregulated markets.[9] By September 2023, the official exchange rate had reached 350 pesos to the dollar, and over 720 pesos on unregulated markets.[10]

Commemorating the National Constitutional Convention, 2 and 5-peso nickel coins were issued in 1994.

2 peso coins were issued in 1999 to commemorate the centenary of the birth of writer Jorge Luis Borges, with Borges portrayed on the obverse and a labyrinth and the Hebrew letter aleph on the reverse. On September 18, 2002, a 2-peso coin with Eva Perón's face was introduced to commemorate the 50th anniversary of her death; this coin was to replace the AR$2 banknote if inflation continued to be high. None of the 2-peso coins are widely circulated.

Some other 50-centavo and 1-peso coins commemorate different events, including the 50th anniversary of the creation of UNICEF (1996); the attainment of voting rights by women (1997); the establishment of Mercosur (1998); and the death of José de San Martín (2001).

Several 1 peso coins were issued in 2010 to commemorate the bicentennial of the May Revolution, all featuring the same obverse, different from the main series, and images of different places on the reverse, including Mar del Plata, the Perito Moreno Glacier, Mount Aconcagua, the Pucará de Tilcara, and El Palmar.

In 2016, the Banco Central de la República Argentina issued a new series of banknotes, with the 200- and 500-peso banknotes as the newest denominations. New 20- and 1,000-peso notes were issued in 2017, and new banknotes of 50 and 100 pesos were issued in 2018. A new series of coins in denominations of $1, $2, $5, and $10 was issued from 2018.[36][37][38]

The design concept of a banknote of 5,000 pesos was shown on 16 May 2020.[39][40] The note was not issued, but the design was used for the $2,000 note announced in February 2023.

In May 2022, the Banco Central de la República Argentina announced a new series of 100-, 200-, 500-, and 1,000-peso notes,[41][42][43][44][45] replacing the animal motifs of the 2016 series with pictures of Argentine historical figures and events while maintaining the color scheme, to be released within the following six months; however, no plans to put these designs into circulation have been made as of May 2023. In March 2023 a $2,000 note was issued, portraying the Instituto Malbrán and pioneering doctors Cecilia Grierson and Ramón Carrillo.[46][47] It does not have a security thread, and uses the design and plates originally intended for the $5,000 note described in May 2020.[48] The new $2,000 note was put into circulation on 22 May 2023.[49]
