By 1953, Uruguay was grappling with the severe economic consequences of the long-standing
Batllista model, which had prioritized a generous welfare state and industrial protectionism funded primarily by booming wool and beef exports. The post-Korean War collapse in global commodity prices exposed the structural weaknesses of this system, leading to chronic fiscal deficits, dwindling foreign reserves, and persistent balance of payments crises. The peso, which had been historically stable, came under intense pressure, forcing the government to rely on a complex and unsustainable system of multiple exchange rates and stringent import controls to manage the currency and conserve hard currency.
President Andrés Martínez Trueba, leading a weak collegial executive (the
Consejo Nacional de Gobierno), faced this crisis with limited tools. The Central Bank struggled to defend the official parity, leading to a thriving black market for U.S. dollars where the peso traded at a significant discount. This multi-tiered system—different rates for essential imports, non-essentials, and financial transactions—created distortions, encouraged speculation, and hampered economic planning. Inflation began to accelerate, eroding the purchasing power of wages and undermining the social peace that had characterized mid-century Uruguay.
The currency instability of 1953 was a critical symptom of a deeper economic malaise, marking the beginning of the end of Uruguay's "Switzerland of America" prosperity. Efforts to stabilize the peso were largely stopgap, as the government was politically constrained from making the sharp fiscal adjustments needed. This period set the stage for the more severe stagflation and monetary crises that would define the latter half of the 1950s and 1960s, ultimately contributing to social unrest and the political upheavals that followed.
