1000 Rupiah

Bank Indonesia has issued 1000 Rupiah notes continuously for decades, but the 2022–2023 dating places this squarely in the post-reform series that followed the 2016 redenomination discussions — discussions that ultimately went nowhere, leaving the existing nominal structure intact. Perum Peruri, the state security printer established in 1971 and based in Karawang, West Java, handles the entire Indonesian currency print run domestically, an arrangement that has been a point of deliberate economic policy since the Suharto era.

Watermark-only security at this denomination reflects the note's low purchasing power — roughly six US cents — making sophisticated anti-counterfeiting measures economically unjustifiable against the cost of production.
