In 1880, Peru's currency situation was one of profound crisis, directly stemming from the ongoing War of the Pacific (1879-1884). Following devastating defeats at sea and on land, including the loss of the vital nitrate-rich Tarapacá province, the Peruvian state faced financial collapse. To fund the war effort, the government of President Nicolás de Piérola had resorted to the massive printing of unbacked paper money, known as
billetes fiscales (fiscal notes). This led to rampant inflation and a severe loss of public confidence, as the paper currency's value plummeted against silver and gold.
The monetary landscape was chaotic, characterized by a dual system. The old silver soles, minted before the war, retained their intrinsic value and were hoarded, disappearing from daily circulation. In their place, the devalued paper bills became the primary medium of exchange, but their worth fluctuated wildly based on war news. By 1880, the government was forced to officially recognize this devaluation, setting arbitrary exchange rates for the paper money against the silver sol for tax payments, which further complicated commerce and undermined the economy. In the capital, Lima, and other areas, foreign coins like British sovereigns and Chilean pesos also circulated at a premium.
This monetary disintegration crippled the Peruvian economy, exacerbating the hardships of war. Internal trade was hampered, government revenues became unpredictable, and the population, especially the poor and those on fixed incomes, suffered from the eroded purchasing power of the paper notes. The currency chaos of 1880 was both a symptom and a cause of the national emergency, reflecting a state financing a desperate war through inflation, which would leave deep economic scars long after the conflict ended.
