Confiscation of currency has sometimes occurred through the fine print
of currency reforms. While only a small fraction of currency reforms
world-wide have masked a confiscation, when they don't they are likely
to follow a hyperinflationary bout. Thus, one way or another, currenc
y reforms are emblematic of government reneging on its most idiosyncra
tic liability or extracting monopoly rents from its provision of an ex
change medium. This paper reviews the international experience with cu
rrency reforms over the last fifty years. It focuses on the purported
justifications, mechanism for implementation, common pitfalls and reve
nues associated with actual discriminatory currency conversion exercis
es.
