100 Intis

The Inti replaced Peru's Sol de Oro in February 1985 at a rate of 1,000 to 1 — a redenomination that acknowledged, without solving, the hyperinflationary pressure already tearing through the economy. This 100 Inti note was a high denomination at launch; within two years, inflation had made it effectively petty cash. By 1990, when the Inti itself was replaced by the Nuevo Sol, the cumulative inflation over the currency's short lifespan had exceeded two million percent.

Local printing by the Banco Central de Reserva was a cost and control measure but limited the sophistication of available security features — the watermark being essentially the only anti-counterfeiting element of note.
