In 1983 due to the IMF imposed "austerity budget" it was illegal to hold or spend any foreign exchange (US dollars, Cad, English pounds).
It made being in business impossible which precipitated my closing my two companies in Jamaica.
However, it was a heck of a black market for a while. It was the origin of the street money changers you still see.
Thankfully that kind of draconian regulation is no longer part of the standby IMF agreements
