Investopedia explains BDT (Bangladesh Taka)
The Bangladesh taka was first seen in 1972 when it replaced the Pakistan rupee with an exchange of one for one. Between inception and 1987 there was reduction in value relative to the U.S. dollar. In 1974, in an attempt to offset this, the Bangladesh government started using the International Monetary Fund's compensatory financing facility. By 1987 the devaluation was relatively under control, however the drop in value of the Tk had been from about $0.129 in 1972 to $0.032 in 1987.
