1 000 000 Cordobas overprinted on 1000 Cordobas

Nicaragua's inflation crisis of the late 1980s was severe enough that the Banco Central resorted to overprinting existing 1000 Córdoba notes with a new face value one thousand times higher. The overprint was not a stopgap — it was official monetary policy, reflecting cumulative inflation that had rendered the underlying denomination effectively worthless before the ink was dry on the original print run.

The 1990 series coincided with the final months of the Sandinista government and the monetary reforms that followed the Chamorro election victory. A new córdoba oro replaced the inflated currency shortly after, making these overprinted notes short-lived in circulation.
