On the eve of the Mexican Revolution in 1910, the nation's currency system was a complex and unstable relic of the Porfiriato, the long dictatorship of Porfirio Díaz. The official currency was the silver peso, but the monetary landscape was fragmented. Alongside Mexican-minted silver coins, U.S. gold dollars and silver pesos circulated freely, as did banknotes issued by dozens of private and state-chartered banks. This system, intended to foster foreign investment and trade, created significant regional disparities and a lack of centralized control, leaving the money supply vulnerable to the solvency of individual banks and international silver prices.
The period was marked by a severe shortage of small-denomination currency, which crippled everyday commerce for the majority of the population. While large transactions for hacienda owners and foreign businesses were facilitated by gold and bank credit, peasants and workers struggled to obtain
centavos and
reales for basic purchases. This scarcity led to the widespread use of makeshift solutions: haciendas and companies paid workers with tokens or scrip only redeemable at the company store (
tienda de raya), a practice that deepened debt peonage and was a major source of social grievance fueling the revolutionary unrest.
Furthermore, the Díaz regime's commitment to the gold standard, maintained through foreign loans, created a profound contradiction. The official exchange rate was artificially fixed, but the actual value of the ubiquitous silver coinage fluctuated with the global market. This, combined with the over-issuance of banknotes by poorly regulated banks, led to periodic devaluations and a loss of public confidence in paper money. Thus, in 1910, Mexico's currency was not just an economic tool but a symbol of the regime's inequalities—centralized in its benefits for the elite and foreign interests, yet dysfunctional and oppressive for the rural and working classes, thereby contributing directly to the revolutionary explosion.
