O que é o BTNF:

As ORTN’s (Obrigações Reajustáveis do  Tesouro  Nacional)  foram   criadas em 1.964.  Vigoram até Fev/86.

Com a edição do Decreto Lei 2.284/86 que criou o Plano Cruzado extinguiram-se as ORTN’s e em substituição foram criadas as OTN’s(Obrigações do Tesouro Nacional). Vigoram até Jan/89. Cada OTN era equivalente a 1.000 ORTN’s.

Com a edição da Lei 7.777/89 extinguiram-se as OTN’s e em substituição foram criados os BTN’s (Bônus do Tesouro Nacional). Cada 1000 BTN’s eram equivalentes a 7,95 OTN’s. (*)

Através da Lei 7.799/89 foram criados os BTNF’s que vigoram até 01/02/91, com a edição da Lei 8.177/91. A partir daí, os BTNF’s, como eram indexadores, de grande parte dos contratos celebrados entre pessoas, passaram, informalmente a ser corrigidos de acordo com a varição da TR (Taxa Referencial).

(*) Nota técnica: Uma OTN valia, à época, 6.170,19. A inflação medida pelo IGP-DI/FGV de Jan/89 foi de 28,89%. Então caso a OTN continuasse a existir ela valeria 7.952,75. Como cada 1000 BTN´s eram equivalentes a 1 OTN (projeto inicial) o valor do BTN ficaria em 7,95275, o que ficaria complicado. Resolveu-se dividir por 7,95 para que o BTN ficasse igual a 1,00 unidade monetária da época.
