100 000 Rupiah

Indonesia's switch to polymer for high-denomination notes came directly out of the 1997–98 Asian financial crisis, when the rupiah lost roughly 80% of its value and counterfeit paper notes flooded the market. The 100,000 rupiah denomination was the hardest hit by forgery, making it the logical first candidate for the new substrate.

The printer attribution for this note is genuinely contested. Note Printing Australia held the polymer technology license and is the more likely producer, but Bank of Thailand Note Printing Works appears in some catalog records. The two facilities printed different issues across the broader Indonesian polymer program, and misattribution between them is common in reference literature.
