The Institut d'Émission de l'Afrique Équatoriale Française et du Cameroun was itself a transitional institution, created in 1955 to manage currency for a federation already showing structural cracks. By 1958 — the year de Gaulle's constitutional referendum reshaped the entire French Union — the member territories of AEF were accelerating toward individual independence, which came for all four between 1960 and 1961. This issue had fewer than three years before the issuing authority ceased to exist entirely, absorbed into the nascent CFA franc zone administered by the Banque des États de l'Afrique Centrale.
