Currencies in use before the current Peruvian sol include: • The
Spanish colonial real from the 16th to 19th centuries, with 8 reales equal to 1 peso. • The
Peruvian real from 1822 to 1863. Initially worth peso,
reales worth peso were introduced in 1858 in their transition to a decimal currency system. • The
sol or
sol de oro from 1863 to 1985, at 1 sol = 10 reales. • The
inti from 1985 to 1991, at 1 inti = 1,000
soles de oro. Due to the bad state of economy and
hyperinflation in the late 1980s, the government was forced to abandon the inti and introduce the sol as the country's new currency. The new currency was put into use on July 1, 1991, by Law No. 25,295, to replace the inti at a rate of 1 sol to 1,000,000 intis, or one
inti millón. All inti coins and banknotes with a face value below 10,000 intis were demonetized. Coins denominated in the new unit were introduced on October 1, 1991, and the first banknotes on November 13, 1991. The remaining banknotes denominated in intis ceased to be legal tender after 1992. Since that time, the sol has retained an inflation rate of 1.5%, the lowest ever in either South America or Latin America as a whole. Since the new currency was put into effect, it has managed to maintain an exchange rate between S/2.2 and S/4.13 per
US dollar. == Coins ==
