The peso boliviano (ISO 4217 code: BOP) was the currency of Bolivia from January 1, 1963, until December 31, 1986.

On December 15, 1959, Bolivia had introduced a comprehensive economic stabilization program that abolished most currency restrictions on the boliviano, which had suffered badly from inflation.

This rate was maintained until November 30, 1979, when the peso boliviano was put on a controlled float, initially at 25.00 per dollar.

President Paz Estenssoro announced a free exchange rate for the peso, which was floated on August 29, 1985, resulting in an effective devaluation of 95%.

Fearing that these poorer quality notes were forgeries, people avoided them to such an extent that after a few months Banco Central Bank resumed issuing the older type of 100.
