Any intervention, such as that of the German Reichsmark in the Spring of 1923, in which only a small part of the increasing note-expansion was recovered by the banks through the sale of foreign bills, would necessarily be unsuccessful. Led by the idea of opposing speculation, inflationistic governments have allowed themselves to become involved in measures whose meaning is hardly intelligible. Thus, at one time the importation of notes, then their exportation, then again both their exportation and importation, have been prohibited. Exporters have been forbidden to sell for their own country's notes, importers to buy with them.
