10 000 Guaranies Spanish value on reverse

Paraguay's highest denomination at the time of issue, the 10,000 Guaraní note emerged during a period of sustained inflation that had been grinding through the economy since the late 1950s. The Stroessner government's monetary stabilization program, backed by IMF agreements in the early 1960s, was supposed to render such large denominations unnecessary — instead, this note entered circulation as evidence that the program was still incomplete.

De La Rue's involvement here is routine for the region, but the bilingual denomination treatment — Spanish value text relegated to the reverse — is an unusual layout choice for a Paraguayan issue of this series.
