By virtue of the first of these principles, that of the fixed exchange rate, the CFA and Comorian francs are firmly pegged to the French currency, called the 'anchor currency': that is to say that their value in French francs does not change depending on the economic situation. It can only be modified by the political authorities of the franc zone. Thus, between 1958 and 1994, 1 CFA franc always bought 0.02 French francs (1 French franc was worth 50 CFA francs).
