Currency in Indonesia is the Rupiah. As a rule of thumb, we use 1 USD equal to 10,000 Rupiah...another relatively worthless currency. Give the money changer a hundred dollars...become an instant millionaire. As value of the dollar has been slowly increasing, it's getting cheaper to live here...but not much. The cost of living for expatriates is far from cheap. Currency continues to slide. When I arrived, the Rupiah was about 9,600 to the dollar. The US Fed was buying back debt and the Rupiah slide to over 11,000 to the dollar. Since the Fed stopped buying back debt, the Rupiah is expected to stabilize.
