The rupiah floats freely, so its rate against the dollar and the dirham is set by the market and by Bank Indonesia policy.
Exchange-rate regime
Free-floating. Bank Indonesia abolished the rupiah’s trading band on 14 August 1997 during the Asian financial crisis, moving to a free-floating rate. Bank Indonesia now targets inflation and intervenes only to smooth volatility, not to defend a level.
The issuing central bank
Bank Indonesia, the central bank in its modern form since 1953, is the sole issuer of the rupiah and sets monetary policy.
