I guess Chile's UF (unidad de fomento, development units) is something alike too. Mortgages are usually done using UF.

According to wikipedia (https://en.wikipedia.org/wiki/Unidad_de_Fomento), Chile's UF was created in 1968.

I think the Pinochet dictatorship expanded the UF to be used in financial transactions like mortgages. Large loans such as for cars or college are also in UF.

It would be interesting to know whether Chile's UF served as inspiration to these brazilians.
