The Monetary Crisis of the Nguyen Dynasty and the Premise for French Colonial Monetary Reforms in Vietnam during the late 19th Century

This article analyzes the crisis of the Nguyen Dynasty’s monetary system during the latter half of the 19th century and its role as a catalyst for the monetary reforms implemented by French colonialists. Under the Nguyen reign, national finances were exhausted due to escalating defense expenditures, massive war indemnities stipulated by the Treaties of 1862 and 1874, and chaos in monetary circulation caused by poor-quality coinage. The severe shortage of silver, coupled with the persistence of obsolete financial management practices, significantly weakened the court’s economic autonomy. This environment not only created an opening for the infiltration of Western financial capital but also established an objective premise for the French to impose a new monetary regime. Through the establishment of the Bank of Indochina and stringent customs policies, France systematically replaced traditional currencies with the Indochinese piastre to seize control of economic lifelines and facilitate long-term colonial exploitation. The study concludes that the French monetary reform was not merely a financial modernization but a strategic socio-economic instrument designed to dismantle Vietnam’s national sovereignty.
