The new currency was named after Inti, the Inca sun god.

The inti was introduced on 1 February 1985, replacing the sol de oro which had suffered from high inflation.

Coins denominated in the new unit were put into circulation from May 1985 and banknotes followed in June of that year.

The Inti million was a currency unit adopted on 1st January 1991, by the Supreme Decree n.º 326-90-EF[1] accepted on 16th December 1990.

Both prices and accounting records were expressed in millions of Intis with all the zeros removed.

By July 1, 1991, when the Nuevos Sol was introduced, the majority of the banknotes were withdrawn.
