Exchange rate regime Managed float
Bank Indonesia has applied a floating exchange rate system to the rupiah since 14 August 1997, when the crawling intervention band was abandoned during the Asian financial crisis. The rate is market-determined, but Bank Indonesia intervenes to stabilise the rupiah — in August 2026 through offshore non-deliverable forward, spot and domestic non-deliverable forward transactions — so the regime operates as a managed float.
About the Indonesian Rupiah
The Indonesian Rupiah (IDR) is the official currency of Indonesia, issued by Bank Indonesia, the country's central bank, and legal tender throughout the territory of the Republic of Indonesia. Its symbol is Rp, written before the amount; domestic notation uses a dot as the thousands separator, as in Rp100.000. The rupiah formally divides into 100 sen, but sen coins no longer circulate, and the smallest denomination in everyday use is the Rp100 coin.
Indonesia has applied a floating exchange rate system to the rupiah since 14 August 1997, when speculative attacks during the Asian financial crisis forced Bank Indonesia to abandon its crawling intervention band. The exchange rate is determined by market supply and demand, but Bank Indonesia actively stabilises it: in August 2026 the bank held its policy BI-Rate at 5.75% and reaffirmed that it continues to intervene across onshore and offshore foreign-exchange markets to keep the rupiah stable.
The first rupiah paper money, the Oeang Republik Indonesia (ORI), was issued by the government of the newly proclaimed republic on 30 October 1946. Bank Indonesia itself was established on 1 July 1953 under Act No. 11 of 1953, succeeding the nationalised De Javasche Bank. Amid hyperinflation that would peak at 635.3% in 1966, Presidential Edict No. 27 of 1965 redenominated the currency, replacing Rp1,000 old rupiah with Rp1 new from 13 December 1965.
In the Bank for International Settlements' 2025 Triennial Survey, conducted in April 2025, the rupiah ranked 22nd among the world's most traded currencies, appearing on one side of 0.7% of global foreign exchange turnover with daily trading averaging about USD 64 billion, up from a 0.4% share in the 2022 survey. Since 20 May 2013 Bank Indonesia has published JISDOR, a volume-weighted benchmark for the USD/IDR spot rate computed from real-time interbank transactions.
The 2022 banknote series comprises seven denominations from Rp1,000 to Rp100,000 and has been legal tender since 17 August 2022, the 77th anniversary of Indonesian independence; the Rp100,000 note bears the proclamation leaders Soekarno and Mohammad Hatta. Coins of the 2016 series circulate in values of Rp100, Rp200, Rp500 and Rp1,000. All rupiah banknotes and coins issued earlier remain legal tender throughout Indonesia until Bank Indonesia withdraws them from circulation.

IDR quick facts
- Bank Negara Indonesia, founded 5 July 1946, was originally meant to be Indonesia's circulation bank, but in practice it operated as a commercial lender, leaving that role to the nationalised De Javasche Bank until Bank Indonesia's founding in 1953.
- The word "rupiah" itself predates independence: Japanese occupation authorities renamed the currency unit from gulden to rupiah in September 1944, when a five-denomination note series from 50 sen to 100 rupiah replaced the earlier occupation money.
- The government formed the De Javasche Bank Nationalisation Committee on 2 July 1951 under Law No. 24 of 1951, buying 97% of the bank's shares on the Dutch stock exchange at 20% above par value, two years before Bank Indonesia's founding law took effect.
- The 2022-series Rp100,000 note measures 151 by 65 millimetres and is printed on cotton fibre; its reverse depicts the Betawi Mask Dance set against the Raja Ampat archipelago, alongside the Moon Orchid.
- Indonesia's currency law (UU No. 7/2011) makes refusing to accept rupiah as payment within Indonesia, barring doubts about its authenticity, a criminal offence carrying up to one year's imprisonment and a Rp200 million fine.
