In 1921, Tunisia's currency situation was defined by its status as a French protectorate, established in 1881. The monetary system was under the direct control of the French administration, which had replaced the former Ottoman and local currencies with the Tunisian franc. This currency was pegged at par to the French franc, effectively integrating Tunisia into the French Franc Zone. This arrangement facilitated colonial trade and financial extraction, ensuring that Tunisia's economy was tightly bound to and dependent on that of metropolitan France.
The primary institution governing currency was the
Banque de l'Algérie et de la Tunisie, a private French bank granted the privilege of issuing banknotes for both territories. While this provided a degree of monetary stability, it meant that Tunisia had no independent monetary policy; decisions were made in the interest of the colonial power and the bank's shareholders. In practice, alongside the official banknotes, French coins and older metallic currencies often circulated, especially in rural areas, reflecting the incomplete and imposed nature of the monetary unification.
Economically, the fixed parity and linked currency system streamlined the export of Tunisian agricultural products (like wheat and phosphates) to France and the import of French manufactured goods, reinforcing a colonial economic structure. However, it also left Tunisia vulnerable to monetary policies set for France's needs, not its own. The stability of the 1921 period was thus a colonial stability, predicated on the subordination of local financial sovereignty, a system that would remain largely unchanged until the struggle for independence decades later.
