In 1909, the currency situation in French Indochina was characterized by a state-managed monetary transition and consolidation. The cornerstone of the system was the
French Indochinese Piastre (piastre de commerce), a distinctive silver coin minted since 1885. Unlike France itself, which was on the gold standard, Indochina operated on a silver standard, giving its currency a high intrinsic value and making it a strong regional trade coin, particularly coveted in neighboring China. This created a persistent problem of piastres being hoarded or exported for their bullion value, often leaving the colony short of circulating currency.
To address this and streamline the economy, the authorities were in the process of implementing a major reform initiated with the decree of January 1903. This established the
Bank of Indochina (Banque de l'Indochine) as the sole issuer of paper money for the federation. By 1909, the bank's notes were becoming increasingly central to commerce, circulating alongside the silver piastre coins and various subsidiary coins. The system was deliberately
overvalued, with the piastre pegged at 2.5 French francs, a rate far above its metallic value in the Asian silver market, designed to tie the colony more firmly to the French economy and facilitate capital transfers.
Consequently, the monetary landscape was a dual one: a theoretical silver standard coexisting with a growing fiduciary system controlled by a French colonial bank. This arrangement privileged French businesses and administrators, as the artificial exchange rate made imports from France cheaper but hindered exports from Indochina. For the local population, the system was often opaque and exploitative, integrating their economies into a framework designed for colonial profit and fiscal control, setting a precedent for financial management that would last until the end of the colonial era.
